Description
Technical Field
[0001] This utility model belongs to the technical field of mining equipment, and specifically relates to a crushing roller with replaceable teeth for a mining crusher. Background Technology
[0002] After mining, the stone needs to be crushed to facilitate subsequent processing or collection. A roller crusher consists of two rollers, each driven by a separate motor, rotating in opposite directions. The ore is fed in from the top, and crushing takes place in the gap between the two rollers. The crushed material is discharged by gravity. When crushing certain harder ores, the teeth of the crushing rollers may wear down.
[0003] A search revealed that Chinese Patent Publication No. CN219647633U, authorized on September 8, 2023, discloses a replaceable tooth crushing roller for a mining crusher. The roller includes two end plates, with a mounting shaft fixedly connected to the axis of the opposite sides of the end plates. Several mounting plates are positioned between the two end plates, with the length of each mounting plate matching the distance between the end plates. These mounting plates are evenly distributed circumferentially around the axis of the end plates. By placing several replacement seats as needed on the surface of the mounting plates, ensuring a suitable distance between them, and fixing them with bolts, the mounting plates are then sequentially placed between the two end plates and fixed with plug-in components. The mounting plates are then evenly distributed circumferentially around the axis of the end plates. Finally, the mounting shaft is installed into the equipment for use. For replacement, only the replacement seats need to be disassembled individually.
[0004] However, the device still has the following drawbacks: Although the above embodiment achieves individual cone head detachability, the entire mounting plate detachability, and adjustable cone head spacing, reducing replacement costs and improving practicality, during use, crushed stone pieces are prone to falling into the equipment gaps. If the crushed stone pieces get stuck in the equipment gaps, it will cause deformation of the equipment, thereby affecting the crushing efficiency of the crusher and impacting the use of the equipment.
