Description

technical field

[0001] The invention relates to a stone removing crusher. Background technique

[0002] In existing brick factories and manufacturers of silt ceramsite, it is necessary to use crushers to finely pulverize raw materials. Existing pulverizers mainly include hammer crusher and double-roll crusher. Hammer crusher has disadvantages such as complex structure and low crushing efficiency; currently used double-roll crusher includes a frame and two parallel rollers arranged on the frame. The frame is equipped with a power device that drives the two support shafts to rotate in opposite directions. The two support shafts are equipped with oppositely arranged gravel rollers. When the power device operates, the two support shafts are driven to rotate in opposite directions. Raw materials are put into the top of the rollers, and the two gravel rollers squeeze against each other to crush the raw materials. The double-roller crusher with the above structure is difficult to ...
