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…

What Model Of Double Roller Crusher Is Used For A Production Capacity Of 200 Tons/Hour?
2025-03-08For a double roll crusher with an hourly output of 200 tons, it is essential to first confirm the type of material being processed, as differences in hardness will influence the selection. Then, the feed particle size and required discharge particle size become critical parameters for equipment choice. For instance, larger feed particle sizes may necessitate larger roller specifications or adjustments to the roller gap. Double roll crusher models are typically named based on roller diameter and length. For example, a 2PG1200×800 model indicates a roller diameter of 1200mm and a roller length of 800mm. In terms of output capacity, different models vary in throughput, while material hardness and moisture content also affect actual production rates.
