Shape characteristics of PE compartment liner

Aug 02, 2019

A flat lining is used for the fine grinding bin, and the rising height of the grinding body depends on the coefficient of static friction with the tree slab.


2 The bead lining is used for a silo to raise the grinding body higher and has a larger impact energy.


The 3 rib liner is similar to the bead liner.


4 Wave liners for baseball mills.


The 5 step liner is suitable for crushing warehouses and is widely used. Has the following three advantages:


a) The height of the lifting of the same sphere is uniform.


b) Uniform wear on the surface of the board.


c) The dragging ability of the lining acts on the abrasive bodies of the other layers, reducing the sliding wear between the lining and the outer grinding body, and also preventing the sliding and abrasion between the different levels of the grinding bodies.


6 hemispherical lining for smashing bins.


7 corrugated lining, boltless lining for fine grinding, with small peaks and tightness.


8 graded lining, which can automatically grade steel balls.


The shape of the barrel liner has a great influence on the work of the ball mill. When handling coarse-grained materials, the lining of the ball mill cylinder should be undulating (such as wave shape, convex shape, lap shape and stage shape). This shape liner has the ability to raise the grinding media to a higher height, thereby enhancing the impact of the medium and increasing the productivity of the ball mill. Often used for a section of grinding.


Fine grinding (often referred to as two-stage grinding) is mainly caused by grinding and peeling. The smooth-shaped lining is easy to slide the steel ball, and the grinding and peeling action is strong, so the fine-grinding ball mill cylinder adopts a smooth lining.
