Description

Technical Field

[0001] The utility model relates to the technical field of equipment for crushing and processing oyster shells, and specifically refers to an oyster shell crushing main machine, which can perform sufficient crushing operations on oyster shell materials by gradually applying pressure. Background Art

[0002] Ring roller crushing equipment is the most commonly used equipment for crushing and processing oyster shells. It mainly includes a housing, a crushing main machine arranged at the bottom side of the housing, and a material extraction and discharge mechanism arranged at the upper part of the housing. The oyster shell materials after feeding are crushed step by step by the crushing main machine, and then the crushed materials are extracted and discharged to external powder collection equipment for collection through gas extraction.

[0003] Existing oyster shell crushing main machines generally include a turntable driven by a drive shaft. By arranging several layers of grinding rollers on the periphery of the turntable, a cooperation is formed with a grinding ring fixed on the crusher housing to crush the falling materials step by step. To ensure the uniformity of material distribution, corresponding material distribution plates are fixedly arranged on the upper and lower parts of the turntable of the existing oyster shell crushing main machine. Since the installation and operation methods of the grinding rollers of the existing oyster shell crushing main machine are the same, the step-by-step crushing operation can only improve the crushing rate of the materials, and its effect on improving the crushing effect of the materials is relatively limited.

[0004] Therefore, on the premise of not affecting the installation and operation stability of the grinding rollers, the research purpose of the present utility model is to design an oyster shell crushing main machine that can effectively increase the roller grinding force on the materials step by step to gradually improve the crushing effect of the materials.
