The liner of the ball mill is an indispensable part of the ball mill. The liner of the ball mill can protect the cylinder from the direct impact and friction of the grinding body and materials. However, the lining plate is a vulnerable part. During the operation of the mill, the lining plate will be constantly impacted and abraded by steel balls and materials, and will also be corroded by pulp. The lining plate will be constantly worn and damaged. What is a good way to solve the wear problem?
The steel ball and lining plate shall be selected reasonably. In case of low load operation, timely adjust the coal feeding amount of the ball mill. The fixing and tightening wedge holes of the lining plate shall be designed into a circular arc to avoid stress concentration. Strictly control the medium, reduce the content of gangue and improve the grindability coefficient of coal. For the ball mill with newly replaced lining plate, according to its characteristics, first use the steel ball with lower hardness for 1-2 months, and then use the steel ball with higher hardness after the hardness and toughness of the lining plate have been improved to a certain extent, so as to improve the service life of the lining plate.
Timely eliminate equipment defects, prevent the expansion of lining plate damage, and ensure the safe and economic operation of the unit. Strictly control the installation quality of the lining plate. If the liner does not match the cylinder, the liner can be replaced or the cylinder can be partially patched. In addition, after the installation and commissioning of the lining plate, the bolts for fixing the lining plate shall be re tightened, and the fixing bolts shall have a certain pre tightening force to prevent the bolts from loosening during operation.
The performance and service life of the liner is one of the technical and economic indicators concerned by users. The material selection, structural form, installation points of the liner are the key points of product design concerned by the ball mill designers. SMMVIK Machinery provides you with wear-resistant ball mill liner, please feel free to purchase.
