supplyLining plate

What is the groove mill liner? The working surface of a single liner is a liner with several grooves. The lining board, installed in the mill, will form a ring groove, so it is also called the ring groove lining board. The grooves on the lining plate of the groove mill are designed so that the steel balls are stacked in a hexagon on the grinding lining plate. The coordination number of steel balls in this packing form is large, the density is high, and the effective collision probability between the balls is more. In addition, the contact between the ball and the liner is changed from the point contact with the flat liner or the convex liner to the line contact of 120°, and the grinding area is sharply increased.

Under this contact condition, the material between the ball and the liner is not as easy to splash around as when the flat liner or convex liner is installed, but forms a layer of material that is not easy to fall off, and is fully ground in the trench, so the grinding efficiency is high. Groove mill lining plate has three forms of ring groove, spiral groove and activated lining plate, which can produce reasonable classification of steel ball and improve grinding effect according to mill working conditions. The above is the introduction of the groove mill liner, you can use it as a reference to understand.
