experimental study on the grinding rate constant of solid

The grinding rate constant, in the widely accepted first-order expression of grinding rate, is one of the important factors required to evaluate a grinding process particularly for its initial grinding stage of various mill types.

In this study, we conducted grinding tests on silica glass, limestone and gypsum using a laboratory ball mill, and measured the grinding rate constant of the feed size reduction. We investigated the effects of feed size and ball diameter on the grinding rate constant of the materials used when the mass of balls, mass of feed, and the mill's rotational speed were constant.

The results indicate that the variation of the grinding rate constant with feed size of the materials can be expressed by revising the equation proposed by Snow. For the grinding rate constant of each material, empirical equations were developed to express it as a function of feed size and ball diameter.

Raw materials are stored in the raw material storage. One belt weigher is set at the bottom of the raw material storage for weighing the raw materials. The weighed raw materials will be transported to the vertical mill system by the belt conveyor.

The limestone from the raw material system is fed into the vertical mill by rotary feeding valve for drying and pulverization. The raw materials fed into the mill are extruded by the grinding roller on the rotating grinding disc. Being crushed under a certain load, the ground materials is sent to the powder concentrator at the upper part of the vertical mill by hot air for sorting into coarse powder and fine powder; the fine powder is the final products, which will be collected by the high efficiency bag filter and sent to the final product system via the chute and bucket elevator.

The coarse powder fell on the grinding disc for re-grinding. In order to save energy, some of the coarse powder is discharged from the vertical mill and is returned to the vertical mill for re-grinding through the belt iron separator, bucket elevator and belt conveyor.
