Different Types of Rock Crushers

Different Types of Rock Crushers

Crushers are primarily used for the crushing of rock and stones, the recycling of building debris, and aggregate production. The purpose of this device is to reduce significant solid raw material volumes to small rocks. They also aid in transforming waste materials into forms that may be easily disposed of or recycled.

A crushing device should crush the rock and offer methods for continuously presenting uncrushed material to the crushing zone and the continual discharging of crushed materials from the crushing area.

One of the biggest problems for businesses maximizing earnings and winning tenders is waste in a changing market. However, materials can be reused in various sectors of industrial applications with the correct crushing application.

Types of Rock Crushers:

Crushers are classified into three kinds; primary, secondary, and tertiary crushers. The feeding technique determines the type of Crusher. It’s these

1. Jaw Rock Crusher:

A jaw crusher is one of the most used primary crushers in a mining or ore processing facility. The rectangular or square aperture at the top of the jaws determines the size of a jaw crusher. Primary jaw crushers often have square openings, but secondary jaw crushers typically have rectangular openings.

A Jaw Crusher compresses big rocks or ore to decrease their size, mainly used as Industrial Rock Crusher. The stationary breaking surface is a fixed jaw placed in a “V” alignment, while the moveable jaw puts force on the rock by pushing it against the stationary plate. 

Due to their smaller physical size, jaw crushers are also excellent for local places, such as underground mining and portable crushing applications.

Newer jaw crusher types have a greater emphasis on safety and ease of maintenance. Hydraulic separation and separate lifting of shells are becoming more popular, creating a safer working environment for any personnel on-site who use the equipment.

2. Impact Rock Crusher:

An impact crusher is a machinery that reduces the material, size by hitting it rather than using pressure. Depending on whatever processing step the equipment is used in, impact crushers are classified as primary, secondary, tertiary, or quaternary rotor crushers. 

Impact crushers can be used as primary, secondary, or tertiary crushers, depending on the ultimate product size requirements of the Producer.

Impact crushers are offered in fixed, track, and portable versions to fulfil the needs of these sectors. In addition, since impact crushers have a tremendous running cost than other crushers, they create a more consistent particle shape ideal for hot asphalt makers and produce more fines. Horizontal Shaft Impactor (HSI) and Vertical Shaft Impactor (VSI) are two common types of impact crushers (VSI).

The new impact crusher models are designed for maximum feed size, desired output size, and overall capacity. The latest versions can produce building aggregate, artificial sand and stone elements, and run-of-mine material, mainly intermediate and tertiary crushing phases.

3. Cone Crusher:

Cone crushers are commonly used in secondary and tertiary crushing applications. A cone crusher operates similarly to a gyratory crusher in that the cone or mantle travels quirkily concerning the bowl. 

The main changes are that the cone moves across a considerably greater distance and works faster. In addition, the cone and bowl arrangement provides a significantly flatter crushing angle than the gyratory.

Cone crushers have two primary crusher designs: normal and short-head variants. There are several liner combinations for each: coarse, moderate, and acceptable for both the cone and the bowl. The pi will decide the first settings in throughput and the top size of the feed. 

Operations and maintenance staff can then analyze equipment wear, maintenance, and operating characteristics to see whether better performances can be reached by altering the shape of the liners.

4. Roll Crusher:

It is a subsidiary or reducing Crusher consisting of a hefty frame with two rollers placed on it. These are powered in such a way that they rotate in the same direction. The rock is fed in from above, crushed, then released at the bottom.

The newest versions include belt-driven Roll Crushers in four configurations: Single Roll, Double Roll, Triple Roll, and Quad Roll Crushers, which give a significant return on investment by running at a low cost and optimizing output by producing minor fines. 

The rigid design, which includes a steel structural base frame, can withstand the harshest mineral processing implementations while offering safe operation, such as a fully automated tramp relief system that allows uncrushable items to move while the Crusher is still in the procedure.

5. Gyratory Crusher:

The gyratory crusher, like the jaw crusher, has a crushing chamber with a continuous crushing aperture. An eccentric drive the crushing action by swinging the base of the crusher mantle about the bowl and concave.

When it comes to regulating input rates, gyratory crushers are more flexible than most other crushers. End dumps from haul trucks are often fed into the crushing chamber using gyratory crushers.

6. Ball-Mill Crusher:

A ball mill is a grinder used to grind, blend, and mix materials for use in mineral processing operations, paints, pyrotechnics, ceramics, and selective laser. 

It operates on the impact and attrition concept: size reduction is accomplished by impact as the balls drop from near the top of the shell. 

The machine’s newer versions are extensively employed in cement, silicate goods, new construction materials, corrosion products, fertilizer, glass ceramics, and other industrial purposes of all kinds of ores. Other grind-able materials may be dry or wet grinding.

7. Hammer Mill Crusher:

A hammermill is a rock crusher machine that uses a hail of hammer blows to shatter and shred various materials. 

The latest variants of this equipment produce high-quality cubical aggregates with improved soundness. 

The HammerMaster comes in three sizes, is well-known for producing high-quality asphalt chip material, concrete stone, general foundation material, and road rock. This Mill may also produce agricultural lime for pH management in agriculture fields.

8. Road Mill-Crusher:

Rod mills operate in tandem with the outer gear. Using input devices, materials are spiralled and uniformly fed into the crushing chamber along the hollow input axis. 

Steel rods of various sizes are placed in the crushing chamber. As a result, centrifugal force is created as the frame rotates. 

At the same time, steel rods are transported to a certain height before falling to grind and hit the material. The powder is released via an output material board after being crushed in the crushing chamber.

This machine’s latest variants are powered by a motor with a speed reducer and a big peripheral gear or a low-speed synchronous generator with a large peripheral gear. 

The grinding intermediate steel rod is placed in the raised cylinder, falling under centrifugal force and shear stress. 

The materials that enter the cylinder through the feeding inlet are ground by a moving grinding medium emptied by overflow and continually fed.

9. Tracked Impact Crusher:

The total capacity of portable impact crushers ranges from 100 to 500 tonnes per hour. Thus, mobile impact crushers are particularly well-suited for smaller-scale recycling, on-site recycling, and urban and roadside operations with limited space. 

These machines are trailer-transportable, drive off at the material area to be crushed, and begin to work faster.

 Portable impact crushers, with their capacity to generate accurately sized, cubical-shaped end products, operate well as stand-alone plants or may add substantial productivity to any operation when used in combination with a jaw crusher or screen unit.

10. Stationary Crushers:

Stationary crushers are a combination of several roller crushers and are an excellent choice for all crushing operations.

They have specifically designed teeth, protective devices, and scraper mechanisms ideal for handling clinging applications.

Stationary Crushers have capabilities of up to 13000 tons per hour, allowing you to maintain high production while generating high-quality products.

The newest versions are minor and take up little room. Depending on the application and input material, the crushing rollers are outfitted with crushing rings, segments, or crushing picks. 

The roll drive system is made up of separate electric motors for each roll and connections and gears. Standard components are utilized to save money and make maintenance easier.

How does a Rock Crusher Work?

Material is crushed by applying reciprocating pressure to a fixed and moving plate until the crushed product is small enough to pass through the gap between the crushing trays. 

We now understand how Rock Crusher Works. The second thing that comes to mind is, “How to crush rocks?” And the short answer is: there are many methods for crushing, some of which are discussed above. 

And some of which are: you can use a granite crusher machine, quarry crusher machine, and many rocks crushing companies: they have colossal rock crushing plants that can do the job for you, or they can provide you with rock quarry or crusher equipment.

What are Stationary Crushing Plants?

You can select between fixed and portable/modular crusher plants depending on the length of your project and how mobile your crushing equipment has to be.

Stationary plants have traditionally been favoured because they offer better efficiency and capacity, lower operating costs, and require less maintenance. They also have a reduced energy expense if you have on-site electricity, and no additional equipment is needed to transfer them from one location to another.

Kemper Equipment has the Crushers you need for your Operation:

Kemper Equipment provides high-performance crushing equipment that will work hard to efficiently create whatever final goods you intend to manufacture, such as sand, gravel, fertilizer, specialized mineral products, recycled asphalt, salt, coal, and slag.

How does a Gold Ore Crusher work?

The tiny rocks will be crushed into powder using a mortar and pestle made of stone or cast iron. Lastly, You can use a flour sifter to filter the dust from bigger particles. Finally, cover the rocks in a towel and lay them on a pretty hard surface to begin your gold recovery.

What Factors should be considered before choosing a Crusher?

Factors such as abrasiveness and hardness: It is critical to understand the material that will be crushed, particularly its abrasiveness and hardness.

The measurements: You must examine the maximum dimensions you may enter into the machine (length, width, and thickness).

A granulometry requirement is required: It is necessary to provide the grain size’s intended outcome after crushing.

The ability (throughput): You must determine the processing capacity (or throughput) required for your application. This is expressed in tonnes per hour.

Other Factors To Consider: While stationary crushers benefit from being more robust, it may be more advantageous to use a mobile crusher to bring the Crusher closer to where it will be needed. For example, a truck can transport wheeled crushers to a building site. 

Because these devices are typically self-contained, they do not require an extra diesel engine to function. Crawler crushers are intended to be continually relocated. They are smaller and lighter than mobile wheeled crushers.

Mobile crushers smash in the same ways that stationary crushers do. They also contain a feeder and conveyors to feed the Crusher and a second conveyor to remove the finished product for separation.


Manufacturers of crushing equipment like rock crushers and Kemper Equipment have expanded their product lines to provide new capabilities for these markets. Mobility and adaptability have been essential elements in creating new models, with many companies now providing new choices in the form of electric and hybrid propulsion systems.
