Introduction to Stone Crusher:

Stone crusher, also known asStone crusher，Stone sand making machineWait. There are many types of stone crushers commonly used in crushing production lines, such as:Jaw crusher、Hammer crusher、impact crusherWait, what is the stone crusher we will introduce to you todayRoll Crusher.
The stone crusher (roller crusher) is an equipment that has evolved from years of wind and rain to the current high-efficiency processing capability. It can process ore materials and other non-metallic materials with relatively high hardness, reducing the particle size of the finished materials to meet the high and low application needs in other fields, or to undertake the next step of application needs. It is widely used in the market and has been well used, meeting the needs of an industry and manufacturers with a demand for ore materials, and making a contribution to the development of China's industrial economy.
Stone crusher (roller crusher) is suitable for processing materials with feed particle size less than 80mm. The stone crusher is suitable for coarse and intermediate crushing of brittle block materials in industries such as cement, chemical, power, mining, metallurgy, building materials, refractory materials, and coal mines. It has a large input particle size and adjustable output particle size, and can crush materials with compressive strength ≤ 160MPa. The crushed material has uniform particle size and low crushing rate, which simplifies the coal preparation process and reduces investment and production costs.
Roller crushers can be classified according to the number of rollersRoll Crusherandfour-roll crusher.
Double roll crusher: It consists of two rotating rollers and a jaw plate; Suitable for laboratory crushing of various medium and low hardness ores or rocks in geological, metallurgical, power, building materials, chemical, coal, mineral processing, research institutes and other units;
Four roll crusher: made by overlapping two double roll crushers

Structure and working principle of stone crusher

Working principle diagram of double toothed roller crusher

The stone crusher is mainly composed of rollers, roller support bearings, clamping and adjusting devices, and driving devices.
The stone crusher (roller crusher) drops the crushed material into the space between two rollers through the feeding port for squeezing and crushing, and the finished material naturally falls down. When encountering hard or unbreakable objects, the rollers of the stone crusher can automatically retreat by the action of hydraulic cylinders or springs, increasing the gap between the rollers and causing the hard or unbreakable objects to fall, thereby protecting the machine from damage. The two rollers rotating in opposite directions have a certain gap, and changing the gap can control the maximum discharge particle size of the product. A stone crusher (roller crusher) uses a pair of circular rollers that rotate in opposite directions for crushing operations.

Technical parameters of stone crusher

Note: The equipment model parameters are constantly being improved. If you cannot find the required model in the parameter table, you can contact us directly. Our technicians will configure the equipment that best suits your production needs and site requirements according to your requirements.

Performance characteristics of stone sand making machine
1. The stone sand making machine is equipped with dust-proof plates inside, which have good sealing performance.
2. The stone sand making machine has a simple and compact structure, occupies a small space, and is easy to operate.
3. The stone crusher has the advantages of long service life, low damage, and easy maintenance.
4. The stone sand making machine is lightweight, small in size, produces less dust, has low working noise, requires less maintenance, and has low cost.
5. The structure is simple and reasonable, with low operating costs, smooth operation, high efficiency and energy saving, high crushing efficiency, and adjustable discharge particle size.

Roll skin and vulnerable parts of roller sand making machine

When the stone crusher is working, special attention should be paid to the following matters:
1. We need to strengthen the iron removal work for mines. Non broken objects (such as drill bits) falling between the double rollers can damage the crusher and cause parking accidents. So an iron removal device should be installed before the crusher.
2. Viscous materials are prone to clogging and crushing spaces. When dealing with blockage faults, the vehicle should be stopped for handling and mining should not be carried out during operation.
3. When dealing with materials containing a large amount of large chunks, it is important to note that large chunks of ore can easily be squeezed out of the crushing space to prevent injury or equipment damage.
4. After running for a long time, the double roll crusher may experience excessive wear on the roller surface, which can cause the product particle size to become too fine. At this time, attention should be paid to adjusting the discharge port or conducting equipment maintenance.
5. Strengthen the inspection of the double roll crusher equipment, lubricate the lubrication parts of the equipment on time, and maintain good lubrication status of the equipment.

Introduction to Stone Sand Production Line
The stone is evenly fed by a vibrating feeder to the jaw crusher for coarse crushing. The coarse crushed material is sent by a belt conveyor to the stone sand making machine for further crushing. The finely crushed material is transported to a vibrating screen for screening. The material that meets the required particle size for the finished product is sent to the sand washing machine for cleaning. After cleaning, it is output by the finished product conveyor belt as the finished product; Materials that do not meet the particle size requirements of the finished product are returned from the vibrating screen to the stone sand making machine for reprocessing, forming a closed loop with multiple cycles. The particle size of finished products can be combined and graded according to user needs. If the dry production process is chosen, a coarse and fine powder separator and dust removal equipment can be equipped.
