Introduction to Marble Natural marble is a metamorphic rock formed by the high temperature and high pressure inside the Earth's crust from pre-existing rocks. Belonging to medium hard stone, mainly composed of calcite, limestone, serpentine, and dolomite. Its main component is calcium carbonate, accounting for more than 50%. Other materials include magnesium carbonate, calcium oxide, manganese oxide, and silicon dioxide. Due to the presence of impurities in marble ..

Introduction to Marble Crusher

Marble crusher (roller crusher), also known asMarble crusher, marble sand making machineWait. Mainly used for fine crushing operations with ore particle size less than 80mm. It has the advantages of small size, high crushing ratio, low noise, simple structure, and easy maintenance. The crushed material has uniform particle size, low over crushing rate, and the finished product particle size is between 0.5-40mm.

Marble crusher (roller crusher) is a pair of cylindrical rollers installed horizontally parallel to each other on the frame. The front and rear rollers rotate in opposite directions, and the material is added to the feeding box and falls on top of the rotating rollers. Under the frictional force on the surface of the rollers, the material is pulled between the rotating rollers and crushed by the compression of the rollers. The crushed material is pushed out by the rotating roller and discharged downwards. Therefore, the crusher operates continuously and has the function of forced unloading, and the crushing of sticky and wet materials does not cause blockage.

Method for adjusting the discharge particle size of a roller crusher: A wedge-shaped or shim adjustment device is installed between the two rollers, and the top of the wedge-shaped device is equipped with an adjustment bolt. The size of the discharge particle can be adjusted by adjusting the bolt: when the adjustment bolt pulls up the wedge block, the wedge block pushes the movable roller wheel away from the fixed wheel, that is, the gap between the two rollers increases, and the discharge particle size increases. When the wedge block is lowered, the gap between the two rollers of the movable roller wheel decreases under the action of the compression spring, and the discharge particle size decreases. The gasket device of the roller crusher adjusts the particle size of the discharge by increasing or decreasing the number or thickness of gaskets. When adding gaskets, the gap between the two rollers increases, and when reducing gaskets, the gap between the two rollers decreases, resulting in a smaller discharge particle size.

Marble crusher is suitable for materials

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

The marble crusher is mainly composed of rollers, roller support bearings, clamping and adjusting devices, and driving devices.
Working principle of marble crusher:

The marble crusher (roller crusher) is driven by two motors using two rollers, which rotate in opposite directions. The crushed material is dropped between two rollers through the feeding port for extrusion crushing. Due to the smooth surface of the rollers in the roller crusher, it not only has the function of crushing but also has the function of grinding. At the same time, under the squeezing and shearing of the roller shaft, the material begins to shatter. The fragmented small particles follow the tangent line of the roller rotation, pass through the gap between the two roller shafts, and are thrown downwards by the machine. Large particles exceeding the gap continue to be crushed into small particles and discharged.
