2PGC-1370A型双齿辊破碎机在石灰石矿山中的应用与改进

Application and improvement of 2PGC-1370A double-toothed roll crusher in limestone mines

2PGC-1370A型双齿辊破碎机已成功应用于煤矿石的破碎。但在石灰石矿山,由于矿源相对偏硬且大块率较高,破碎机在应用过程中出现了齿冠易断、齿环断裂后难以更换、破碎辊轴承内圈易裂的问题。在生产维修过程中,采取以箱式齿冠、复合齿环代替原部件和加装破碎辊轴向止推装置等办法,解决了破碎机生产过程中出现的问题,提高了生产效率,降低了生产成本。

2PGC-1370A double-toothed roll crushers have been successfully used for crushing coal ore.Due to hard and big stone coal,some problems appear during the crusher employment such as the breaking of tooth crow,difficult to repair and replace while the toothed ring has broken,and cracking of the inner ring of bearing for crushing rolls.During the maintenance operation,case-shaped tooth crown and compound toothed ring is applied to replace originals and axial-fixed settings is added to crushing rolls,so as to solve the above problems.Thus,the productivity enhances,and the production costs decrease.
