Roller Crusher: The “Efficient Scissor” For Sand And Stone Production
2025-03-27I.What is a roller crusher? The roller crusher, also known as a double-roller sand making machine, is a device that makes sand by squeezing materials through two rotating roller wheels. It has a simple structure, consisting of roller wheels, bearings, adjustment devices, and driving motors. It is widely used in fields such as construction waste treatment and sand and stone production, and can turn large pieces of material into uniform sand particles. II. Crushing process: Crushing materials like scissors Material enters between the two rolls from above. Into the crushing chamber: the rolls rotate towards each other, and the friction force “pulls” the material into the crushing area. Compression and shearing: the material is compressed and rubbed by the rolls, and is crushed like scissors. Hard objects are repeatedly crushed until they break. Discharge: The crushed sand particles are discharged from the bottom, and the particle size is controlled by the gap between the rolls. How to adjust the size of the sand particles? Wedge adjustment: Turn the bolt, lift the movable roll, increase the gap, and the sand particles become coarser. Gasket adjustment: Increase or decrease the number of washers to change the gap; the more washers, the coarser…
