Introduction to Stone Crusher：

Stone crusher, also known asStone crusher，Stone sand making machine，Stone sand making machine，Stone crusherWait. The stone crusher (roller crusher) uses two sets of separately driven roller shafts to crush materials by generating squeezing force and grinding shear force through relative rotation.

After the material enters the crushing chamber of the machine, it is subjected to the meshing force of the rotating roller shaft, forcing it to pass between the two rollers while being squeezed and sheared by the roller shaft. The material begins to shatter, and the fragmented small particles are thrown down the machine through the gap between the two roller shafts along the tangent line of the roller rotation. Large particles exceeding the gap continue to be crushed into small particles and discharged.
According to the customer's crushing fineness and production capacity, in addition to using a twin roll crusher, a four roll crusher can also be used for crushing.four-roll crusherIt has many advantages such as finer crushing fineness and greater production capacity.

Application of stone sand making machine
Stone crusher (roller 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, coal mines, etc. Its feed particle size is large and the discharge particle size is adjustable. It can crush materials with compressive strength ≤ 160MPa. Especially in the coal industry, when using this machine to crush raw coal, it can be directly crushed as long as it undergoes iron and impurity removal without the need for gangue removal. The crushed material has uniform particle size and low over crushing rate, simplifying the coal preparation process and reducing investment and production costs.

Suitable materials for stone sand making machine

cobble	calcite	quartz	marble
pebble	stone	iron ore	limestone

River pebbles, calcite, quartz, marble, pebbles, bentonite, iron ore, bluestone, mountain stones, water slag, limestone, weathered sand, diabase, granite, basalt, etc.

Working principle of stone sand making machine

Working principle diagram of double toothed roller crusher

The stone sand making machine (roller crusher) drops the crushed material through the feeding port into the space between two rollers for squeezing and crushing, and the finished material naturally falls down. When encountering hard or unbreakable objects, the rollers of the roller crusher can automatically retract by the action of hydraulic cylinders or springs, increasing the gap between the rollers and preventing the hard or unbreakable objects from falling, thus 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. The double roll crusher uses a pair of circular rollers that rotate in opposite directions, while the four roll crusher uses two pairs of circular rollers that rotate in opposite directions for crushing operations.

Advantages of stone sand making machine
1. The stone sand making machine is equipped with a hydraulic automatic retreat device, which can effectively prevent the damage of iron blocks to the toothed roller and the harm of wooden blocks and flexible objects to the normal operation of the toothed roller.
2. The stone crusher is equipped with an intelligent cleaning device, which can automatically remove the adhered materials on the chamber wall of the crusher at intervals of working conditions.
3. This stone sand making machine has become the preferred equipment for replacing imported crushing equipment in thermal power plants due to its advantages of high efficiency, energy saving, and environmental protection.
4. The stone crusher adopts multiple protective devices and interlocking devices such as mechanical, electrical, and hydraulic, effectively protecting the motor, crusher, and the entire system.
5. Compared with other types of crushers, the stone sand making machine has the advantages of high crushing ratio, no requirement for moisture content of crushed materials, no stickiness or blockage, less over crushing, low noise, low vibration, less dust, low energy consumption, small footprint, and simple and convenient maintenance.

Introduction to Stone Crushing Production Line
Large stones are uniformly fed into the jaw crusher by a vibrating feeder through the material bin for coarse crushing. After coarse crushing, the stones are transported by a belt conveyor to the stone crusher (roller sand making machine) for further crushing. The stones from the stone crusher (roller sand making machine) are transported by a belt conveyor to the vibrating screen for screening, and several different sizes of stones are screened out. The stones that meet the particle requirements are sent to the finished material pile by the finished product belt conveyor. The stones that do not meet the particle requirements are returned by the belt conveyor to the stone crusher (roller sand making machine) for further crushing, forming a closed loop with multiple cycles. The particle size of the finished product can be combined and graded according to the user's needs. To protect the environment, auxiliary dust removal equipment can be configured.
