Benefits of Crushing Equipment

Increased Efficiency
One of the primary benefits of using a crusher is increased efficiency. Crushers are designed to break down materials quickly and efficiently, which can save time and money in the long run. By reducing the size of materials, crushers can also make it easier to transport and store materials, further increasing efficiency.

Improved Safety
Another benefit of using a crusher is improved safety. Crushers are designed to be operated safely, with features such as safety guards and emergency stop buttons. This can help prevent accidents and injuries in the workplace, which can be costly and time-consuming to manage.

Reduced Environmental Impact
Crushers can also help reduce the environmental impact of mining and construction activities. By breaking down materials on-site, crushers can reduce the need for transportation and disposal of waste materials. This contributes to reducing the carbon footprint of these industries and promotes more sustainable practices.

Versatility
Crushers are versatile machines that can be used for a variety of applications. They can break down a wide range of materials, including rocks, concrete, and asphalt. This versatility makes them valuable across industries such as mining, construction, and demolition.

Types of Crushing Equipment

Jaw Crushers

Jaw crushers are one of the very first types of crushers. Primary jaw crushers are typified by their square opening design, with secondary jaw crushers usually having a rectangular design. Primary crushers take the biggest pieces of rock and break them up before they move onto secondary crushers, which further break up the pieces. Jaw crushers use compression as their means of breaking up rock. Rocks are pressed up against a stationary plate to crush the materials. These powerhouses of the crushing world can crush almost any material, including hard and soft rock. There are also many different types of jaw crushers designed for very specific materials and uses.

Impact Crushers

Impact crushers use striking to break up raw materials instead of compression like jaw crushers. These types of crushers are popular in all stages of crushing, including primary, secondary, and tertiary. Impact crushers can break up raw materials into specific sizes. The two main types of impact crushers are horizontal and vertical crushers. Horizontal impact crushers use a hammer in its rock breaking jobs, while vertical impact crushers use speed to break up rocks. Rocks are thrown up against a hard surface at precise velocities to break them up into the desired size for their intended use.

Gyratory Crushers

Invented by Charles Brown in 1877 and refined by Gates in 1881, the gyratory crusher is another type of crusher used to crush extremely tough rocks that require a lot of pressure to break apart. They are popular in surface crushing, screening, and crushing plants. Gyratory crushers have concave surfaces and a head shaped like a cone. A mantle gyrates within a concave bowl as compressive force is applied to the rock when the mantle and the bowl meet. These crushers can crush a lot of material in a very short amount of time, and they can crush odd sizes of materials, such as slab rocks, that jaw crushers cannot due to the shape of the feed opening.

Cone Crushers

Many people confuse cone crushers with gyratory crushers because they are very similar. A cone crusher uses the same general construction as a gyratory crusher, consisting of a mantle that rotates within a bowl. However, it is not as steep as a gyratory crusher and has a short spindle beneath the cone. In this case, the force to break the rock up is exerted between the gyrating spindle and the enclosed bowl liner. The cone crusher breaks up larger pieces of materials into gradually smaller pieces as they move through the machine. This process continues until the pieces are small enough to fall out at the bottom of the crusher. Cone crushers are commonly found in mining, aggregate, and recycling applications.

Mobile Crushers

Mobile crushers are track-mounted rock-crushing machines that are easily movable on and between production sites. They are widely used in aggregate production, recycling applications, and in mining operations. Mobile crushers can replace stationary crushing systems, which reduces the need for hauling and cuts operational costs.

Different Working Principles of Crushing Equipment

Extrusion

The material is broken by slowly increasing pressure between two working surfaces.

Grinding and stripping method

The shearing force applied when the material is rubbed by the moving workpiece, or the shearing action when materials rub against each other, causes the material to be pulverized.

Splitting method

The material is crushed by the action of a wedge-shaped working body.

Impact method

The material is pulverized due to impact force. This force is generated by the impact of the moving working body on the material, or when high-speed moving material impacts a fixed working surface, or when high-speed moving materials impact each other. The high-speed moving working body also causes suspended material to impact.

Daily Operation Guidelines for Crushing Equipment

Safety issues have always been a priority in our considerations, especially in production workshops, high-altitude operations, and exposure to chemical substances. Proper operation of crushing equipment and crushers can prevent many accidents. Here, we remind everyone to follow the instructions and conduct operations according to standards.

General Rules

(1) The operator of the crusher must undergo training and assessment, understanding the "three understandings" (structure, performance, principles) and possessing the "four abilities" (operational, maintenance, troubleshooting). They must also hold a valid work certificate.

(2) Coordinate effectively with operators of scraper conveyors and belt transport lanes, maintain unified signal communication, and adhere to orderly start and stop procedures.

(3) When feeding the crusher, avoid mixing large pieces of material to prevent equipment blockage or damage.

Pre-Test Run

(1) The equipment should be installed on a level concrete foundation and secured with anchor bolts.

(2) Ensure all connections such as motor, reducer, hydraulic coupling, head, and tail are complete, intact, and tightly fastened. Check for any oil leakage in the shaft joints of the reducer and hydraulic unit, ensuring oil levels are appropriate.

(3) Verify signal sensitivity and reliability; do not power on without a signal. Ensure the spray sprinkler system is in good condition.

(4) Prioritize vertical alignment and levelness during installation.

(5) Conduct a thorough check after installation to confirm readiness for test operation.

(4) Ensure the stability and reliability of the transfer machine's traveling trolley.

How to Select Suitable Crushing Equipment?

Whether in the field of sand and stone production or construction, efficient crushing equipment can significantly boost production efficiency with minimal effort. However, the market offers a wide array of crushing equipment, posing a challenge for first-time buyers. How should one choose suitable crushing equipment? When selecting a crusher, careful consideration should be given to the type of material, its hardness, inlet and outlet particle sizes, production capacity, and the construction site.

Hardness of Materials
Different materials vary in hardness, and generally, higher hardness levels indicate greater difficulty in crushing. For hard or medium-hard stones, a jaw crusher is recommended as primary crushing equipment. For medium-hard or soft stones, cone crushers, impact crushers, or hammer crushers can be used directly.

For large material sizes, a jaw crusher is suitable as the primary crusher. When smaller stone sizes and specific gradations are required, combined crushing and screening equipment such as jaw crushers paired with cone crushers, impact crushers, or hammer crushers should be considered.

Moisture Content of Materials
The moisture content of materials also influences crusher selection. High moisture levels can cause fine materials to adhere to coarse materials due to increased viscosity, slowing down discharge rates and reducing productivity. In severe cases, this can lead to blockages at the discharge port, disrupting production.

Degree of Ore Cleavage Development
The degree of cleavage in ores directly impacts crusher productivity. Ores with well-developed cleavage fracture more easily during crushing, resulting in higher crusher productivity compared to ores with dense structures that resist fracturing.

Particle Size of Incoming and Outgoing Materials
The particle size of incoming and outgoing materials determines the crusher model and crushing efficiency required:

A high proportion of coarse particles in the crushed material or a large ratio of ore size to feed opening width necessitates a higher crushing ratio, which may decrease productivity.

Conversely, a high proportion of fine particles or a smaller ratio of ore size to feed opening width requires a lower crushing ratio, potentially increasing productivity.

Large feed sizes with small discharge sizes often require secondary or multi-stage crushing. Smaller feed sizes may not necessitate multi-stage crushing.

Production Requirements
Production requirements significantly influence crusher selection. Higher production demands require larger crushing equipment specifications and increased input and output capacities.

Construction Site Considerations
Specific construction site conditions directly impact crusher selection, including site size and the precise placement of crushing equipment.

Components of a Crushing Plant

One of the fundamental materials in the building and construction sector is small stones, obtained by crushing large rocks. This process is carried out in a crushing plant, which consists of four main parts performing different tasks to efficiently crush stone, a task more complex than it appears. These parts are:

Bunker (Feeder)

The bunker (feeder) delivers processed material to the required area, feeding vibrating screens or crushers. It adjusts the output size and increases plant capacity. It comprises two parts: the chamber where stone material is stored and the feeder located just below it.

Primary Crusher (Jaw Crusher)

The jaw crusher is a powerful machine used to obtain hard materials required in production. Available in various sizes and engine powers, jaw crushers can crush and process all types of mines and minerals. They compress material with specially designed jaws and can adjust the gap.

Conveyor Belt

A conveyor belt transports materials obtained in the crushing plant from one place to another. It is commonly used in mines, mineral processing and enrichment plants, crushing, screening, and washing plants. Conveyor belts reduce the workload in crusher plants and minimize manpower use.

Vibrating Screen

The vibrating screen separates differently sized materials obtained after crushing in the crushing plant, ensuring outputs are segregated. This crucial part of the stone crushing and screening system achieves desired material sizes through circular movements during the screening process.
