Hydraulic Crusher – The Definitive FAQ Guide

Hydraulic crusher guide provides you with a series of questions that will help you better understand this excavator attachment. This guide contains information on hydraulic crushers, applications, materials, maintenance requirements, the role of hinges, reasons for failures, and much more. Even you are a pro or a novice, and this guide will provide you with some real insights about the hydraulic crusher.

1. What is a hydraulic crusher?

A hydraulic crusher is used for crushing various rocks in civil engineering to produce aggregate for use in construction. They use hydraulic pressure to split materials by squeezing them between the two anvils. The rotation of each anvil is controlled by a hydraulic cylinder that responds to signals from an operator cabin, which helps determine how much anvil movement will occur.

This leads to the desired result of splitting material based on the size and hardness of the material. They are used in mines, quarries, construction sites, recycling plants, or even garages to help break down rocks into smaller pieces before being shipped offsite for further processing.

2. What is the working principle of a Hydraulic crusher?

The working principle of the hydraulic crusher is based on hydraulics. The hydraulic crusher is attached to the excavator’s arm with the help of a hydraulic coupler. The hydraulic crusher is attached to the hydraulic lines, and these lines supply pressurized hydraulic fluid through the hydraulic pump.

This fluid powers your hydraulic crusher. It helps the upper and lower jaw of the hydraulic crusher to apply force to the material needed to be broken. The jaw has teeth of various sizes and shapes, and this depends on the type of material you want to handle with your hydraulic crusher.

These teeth help split or rip apart the materials; the conical shape of teeth has a more significant impact on the easy breakage of different materials.

3. What are the applications of a hydraulic crusher?

Hydraulic Crushers are used in mining, quarrying, construction, and other types of demolition work. They can compress the material into smaller pieces or break large items down into smaller ones. Hydraulic Crushers are also one of the machines used to crush rock. Hydraulic Crushers can be found in many different forms.

This is because they are often designed to fit the specific needs of the operation that they are being used for. Some common types that you will find include impact crushers, cone crushers, and hydraulic crushers. The Hydraulic Crusher is the ideal crusher for metallurgic processes, pelletizing, and mineralizing.

The hydraulic crusher is widely used in building material, chemical industry, and other industries and has the advantages of a large crushing ratio and high capacity under small volume.

4. Which material is used in making a hydraulic crusher?

The material used in making a hydraulic crusher depends on several factors. The main factors include the type of material you need to handle, the material size, material strength, or hardness. The material widely used in making hydraulic crushers is alloy steel or forged steel, and this is because this type of material has greater hardness associated.

For additional strength, some additives are also used in the primary steel like carbon, manganese to bear the impact of extensive hard materials.P VC pipelines are used in supplying the pressurized hydraulic fluid to your hydraulic crusher. The bolts and screws are made up of cast iron to impart the necessary component joining strength.

5. How would you define the manufacturing process of a hydraulic crusher?

The manufacturing process of the hydraulic crusher is as follows. The material from which it is made is subjected to high heat treatment. After this, a series of steps are followed in the hydraulic crusher manufacturing line. These steps include molding, machining, milling, and at the end coating.

The molten material is put inside the mold is of a shape similar to the hydraulic crusher. Then the molded component is processed through milling and machining steps. After this step, the impact resistance is tested to ensure your hydraulic crusher’s durability and maximum strength.In the end, the coating is performed to prevent oxidation, resulting in resisting the impact of the harsh and challenging working environment.

6. How did I know my hydraulic crusher is terrible?

There are several reasons why your hydraulic crusher is terrible. Some of the main reasons are as follows:

• Inadequate hydraulic fuel supply from your excavator hydraulic pump due to the leakage in any specific line. This will result in loss of power in your hydraulic crusher.
• Damaged or worn-out seals in the hydraulic system of your hydraulic crusher.
• The improper installing method is utilized in the installation of your hydraulic crusher.
• Cracks in the excavator hydraulic crusher body due to facing the disproportionate impact of complex materials.
• If the material gets stuck between the teeth of a hydraulic crusher, this will also indicate that your hydraulic crusher is terrible.

7. Which materials can a hydraulic crusher break?

Hydraulic crushers can break a variety of materials. The material can break depends on the pressure or power developed by the pressurized hydraulic fluid. The particular materials it can break also depend on the size of the hydraulic crusher and the design specifications.

Hydraulic crushers can process high hardness, medium hardness, and brittle materials, such as limestone, coal gangue, barite, gypsum, chalk, granite, ceramic clay (kaolin), quartz (sand making stone), marble, basalt.

Generally, hard materials should be crushed in hard steel crushers, while soft materials should be discouraged in smooth steel crushers. But the operating pressure varies according to the material’s hardness.

8. How much does a hydraulic crusher cost?

The cost of a hydraulic crusher depends on several factors. Some of the main factors include the weight of the hydraulic crusher, design specifications, material with which it is made, and life associated. The cost of a 1500 kg hydraulic crusher with a warranty of 6 months lies in the range of $2500 to $12000 per piece.

The price of a hydraulic crusher weighing 1400 kg with a pin shaft of chromium-molybdenum lies in the range of $4800 to $5800 per piece. The cost mentioned above varies depending on the type of hydraulic crusher you will choose for your particular application. As the size of material and material hardness increases, the strength demands also increase.

9. How long does a hydraulic crusher last?

A hydraulic crusher is typically made of high-quality steel for safety. Its impacts are resistant to protect the unit from damage incurred through high operational pressures. In general, the life associated with hydraulic crushers lies in the range of 2 to 3 years. This life varies depending on several factors.

The main factors that affect your hydraulic crusher’s lifespan include the frequency of usage, operating environmental conditions, and material that is being crushed. If you follow the proper maintenance measures for your hydraulic crusher, it may last longer than the improper maintained hydraulic crusher. Also, properly operating your excavator hydraulic crusher will lead to enhanced lifespan and increased efficiency.

10. What is the role of teeth in a hydraulic crusher?

The teeth of the hydraulic crusher play an important role in grabbing and crushing the desired material. Different shapes of teeth have an extra level of impact in grabbing and crushing the materials. The high manganese steel teeth are specially made for hard stone crushing, and they are sharp enough to guarantee the crusher under high efficiency.

Tooth height, tooth thickness, and tooth tip size are boldly designed according to the capacity required to ensure all materials are over-crushed over time. These parameters are adjusted during the optimization of the crushing process. The phase angle 20~ 30 degrees is suitable for different crush materials like limestone, basalt, granite, natural marble stone, limestone mining, etc.

11. What are the maintenance requirements of a hydraulic crusher?

The maintenance requirements for a hydraulic crusher are essential in the grand scheme of things. If you cannot correctly maintain your hydraulic crusher, you will likely experience an equipment failure that could have been completely avoided. To get maximum value from the machine, maintenance should be done on it regularly.

This means that regular checks should ensure no blockage in the pipes, and all the mechanical parts, including the teeth and couplings for grinding and so on, should be maintained perfectly. Hydraulic fluid should also be changed every 50 hours of working time and checked for oil viscosity and solid content.

12. How to install a hydraulic crusher on your excavator?

The procedure to install a hydraulic crusher on your excavator is as follows. First, you need to align the excavator hydraulic crusher on the flat surface. Take your excavator close to the hydraulic crusher, now first attach the quick hydraulic coupler to your excavator’s arm. Then add your excavator hydraulic crusher to your excavator quick coupler. Install the bolts and screws with the help of a suitable tool kit.

Then you need to install the hydraulic lines to your hydraulic crusher with the help of a nut located at the end of hydraulic lines. Make sure to tighten the nut and screws at optimum torque to avoid any noise or vibrations associated. In the end, test your installation to make sure everything is fine and your hydraulic crusher is crushing materials optimally.

13. What is the role of hinges on the hydraulic crusher?

The hinges on the hydraulic crusher are mainly used for adjusting and fixing the gap between the upper and lower jaw. Doing this will ensure the relative moving conditions of the upper and lower jaw follow the actual size of the material to be crushed. Therefore, during the grinding process, it is required to adjust the gap on the hinge of a vertical shaft on both sides of the vertical shaft connecting with the longitudinal axis.

By adjusting, the size of the gap can be changed, while this gap should not exceed 0.2mm to protect crushing equipment from being damaged due to fine particles that might enter into the gaping hole.

14. What role does a quick hydraulic coupler play in a hydraulic crusher?

A quick hydraulic coupler is a key component without which you cannot operate your hydraulic crusher on your excavator. As the name describes, a quick hydraulic coupler is used to connect and disconnect your several excavator attachments quickly.

This allows you to connect the hydraulic lines and hold your hydraulic crusher with ease on your excavator. The hydraulic coupler is the link between the hydraulic system and the crusher’s drive components.  It is usually mounted on the mainframe or the excavator arm base of the machine. The coupler lever handle is a snap to open and close with a quick pull up or down.

15. Is noise associated with the hydraulic crusher?

Yes, hydraulic crushers cause a moderate amount of noise. The size and power of the motor and operation of the hydraulic system contribute significantly to the decibel (dB.) level. The hydraulic pressure applied to the chamber walls and the impact of the individual cylinder piston compressing against it produce a sound. Still, in normal operating conditions, the sound level is in the range of 70-80 dB.

The noise level is affected by some factors, including the type of machine, feed rate, material being crushed, and the general condition of the device itself. For instance, a hydraulic pressure down to 50 psi means less vibration, and dampening equals less noise.

16. What type of oil goes into the hydraulic crusher?

The hydraulic crusher uses 15W40 engine oil. Its operation is permanently suspended to avoid overload.15W40 engine oil, 20W50 engine oil, and 10W30 motorcycle oil can be used as lubricants for this machine. Different manufacturers specify different types of oils, so it’s essential to be familiar with the requirements of your specific hydraulic crusher before assuming what kind of oil should be used in this equipment.

The type of oil used in hydraulic crushers is mostly synthetic or mineral-based; each oil has its specific characteristics. The special additives in these oils let your hydraulic crusher operates at maximum efficiency.

17. What are the problems associated with the hydraulic crusher?

Here are some of the problems associated with it: The complexities of hydraulics mean maintenance costs are high due to the frequency of wear and tear on many small parts. There’s also a possibility of failure to meet operational expectations. High costs for both material and power mean this design tends to be expensive compared to other crushing systems.

Hydraulic components may not be fitted to existing equipment. Pumps are expensive because they must be built to very high or very low pressures, which are extremely hard to maintain over time. The hydraulic crusher is very unsafe, and the pressure is too high to be around. The high-powered motor can cause severe injury or death if it gets stuck or goes out of control.

18. What characteristics are embedded in hydraulic crusher oil?

The oil is made of high-quality base oil, and sulfur additives developed to meet customers’ drawing on a molecular level. Sulfur additives can effectively depress the temperature under extreme conditions and provide stable viscosity. The main characteristic of hydraulic crusher oil has high wear resistance. It also serves as an emulsifying agent which assists in the concoction process.

Hydraulic Crusher Oil uses 100% synthetic base oil that resists oxidation, thermal breakdown, and foaming to withstand the challenging demands of harsh crusher environments. Plus, Hydraulic Crusher Oil does not leave oily deposits to contaminate pipes or other machinery.

19. How to choose a hydraulic crusher?

Whether you want a small surface mining hydraulic crusher or a large underground hydraulic crusher, there are many factors to consider, including the type of rock being crushed, the application, and the surface overburden. When choosing the hydraulic crusher, you should pay attention to the operation costs, motor horsepower requirement, installation requirements, cutting workpieces, etc.

What power a hydraulic crusher can produce, and what type of material it can be ripping apart. The maintenance requirements and life associated with your hydraulic crusher also play a role in selecting the correct type of hydraulic crusher.

20. Is friction associated with the hydraulic crusher?

Static forces like friction and inertia exist in any system. For example, when a hydraulic motor turns or operates, this causes friction and pressure that will resist the movement. This can cause hydraulic motors to fail prematurely because of the motors’ pressures to endure from these forces.

The Hydraulic Crusher uses the pressure created by the pump to crush material. This pressure is developed by fluid (oil) circulated through an internal chamber, which raises the tension. Friction occurs when the rotor or crushing cage rubs against internal or external surfaces inside the chamber.

This friction adds heat to the system, which must be dissipated. If heat is not removed, lubrication will suffer, and internal components will become damaged.

21. What do you mean by the Hs code of the hydraulic crusher?

The Harmonized System is a naming and classification process for traded products. Customs authorities around the world use this system to identify items and assess their duties and taxes. The Harmonized System also provides statistics for each product. It is a code containing numbers of digits ranging from 6 to 10 and varies from product to product.

It provides information about the quantity of product imported, importation date and time, price per unit, location from where it is imported, etc. The Hs Code helps you in inventory management and relieves you from running out of inventory stock.

22. What causes the failure of a hydraulic crusher?

The failure of a hydraulic crusher is often caused by the incorrect design, selection, and installation of its major components, i.e., hydraulic motor, pump, or other equipment. Hydraulic crushers fail because of the high operating pressure and high impact forces, which can cause permanent deformation or failure of the materials when applied.

The failure of this complex machinery arises from incorrect maintenance and usage. Since there are several hydraulics involved in breaking rock, the risk of failure is higher than that of a simple transporting mechanism. The most common are down pressure on lumps, which damage the teeth, mantle, or bushings.

Another common cause is wearing the pinion gears, especially when crushing concrete with soft aggregate. However, crusher failures may occur because of incorrect tooth space selection, particularly when the crushes are stacked too high in stages.

23. What is the role of angle in hydraulic crusher tines?

Hydraulic crushers are used for crushing hard or abrasive materials.When picking the right tines for your hydraulic crusher, the first thing to consider is what types of materials you intend to crush. Generally, 90 degree turns will work best on small pieces of rock.

If you intend to crush rocks over six inches in diameter, 55 degrees tines are recommended. However, if you are mainly crushing limestone, the tines do not need to be as thick. Applied pressure, or stress, results from the force applied perpendicular to the surface of an object multiplied by the area of that object. Angle has to do with how the tines are shaped, size is how large they are, and spacing is how far apart they are.

24. What is the role of the pointed edge in the hydraulic crusher?

The pointed edge fulfills the role of breaking up material as it is entering the crusher chamber. The pointed edge serves two purposes. First, it gives more weight to the machine, thus creating more force to crush the material. Second, the pointed edge allows the operator to position where they want the rock to be crushed before striking it with large machines.

This saves time and energy needed to move the machine over various striking points across the rock. When the material is loaded into the feeding chute, the pointed edge rolls upward from top to bottom, generating torsional force. Then, the torsional force will be transformed into kinetic energy due to the material’s resistance which will exhaust all of its potential energy, thus resulting in materials breakage.
