In our production will use a lot of liner products, if the operation will be due to improper wear off the liner, specifically because of what can wear the lining of the powerful? There is a problem to understand the problem, so as to be in the course of the operation so that our liner with longer.

(1) the impact of the grinding coefficient of coal

Grinding coefficient is too small, that can be poor grinding, aggravating the wear of the ball mill liner.

(2) the design and manufacture of unreasonable and the impact of the quality of installation

Fixed ball mill liner bolt hole for the square, resulting in the stress concentration, prone to break the site. The quality of the liner installation is critical to the safe operation of the ball mill.

(3) liner with the ball with the wear and tear

Ball mill liner and ball is a wearable piece of ball mill. When the mill is working, the liner is worn by the drop of steel balls and material, and is also slid by the ball. In addition, the wear resistance of the liner increases as the hardness of the material increases. At the same time as the ball and liner is a pair of friction to pay, one side of the increase in hardness is accelerated. So the correct choice of liner and ball with the work in order to make the ball wear and tear at the same time the least wear on the liner.

(4) liner material and heat treatment process does not meet the requirements

High manganese steel liner strength of the lower strength, in the work of the mill in the steel ball, coal impact, grinding under the prone to plastic deformation. It is precisely because of this, so that the ball mill square head bolts by a large shear force, resulting in fixed liner with the bolt is often broken.

(5) the impact of operating conditions

The grinding of coal into the ball mill is not timely, will cause the ball mill less coal, part of the steel ball directly with the liner friction impact, the impact is much larger than usual, so that liner wear, The service life has a direct impact.

(6) did not promptly eliminate defects

Ball mill liner once broken off or fixed bolt break, if not found in time and does not eliminate, it will bring disaster to other liners, serious lead to deformation of the cylinder and so on.

Above are liner manufacturers to introduce you to the liner easy to wear reasons, we should pay attention to the actual operation of the process, the production of the product is not only a thorough understanding of the liner, as well as broken walls, board hammer, etc. products To help you get machined faster and better.
