Abstract
The utility model belongs to the technical field of building material machinery, and discloses a double-layer partition of a fine grinding bin of a ball grinder with a punched discharge grate plate. A discharge grate plate in the prior art is a cast piece, which means that the width of a strip-shaped grate hole cannot be very small (the minimum width is 6 millimeters). When the size of a steel-section grinding body (with a diameter of 10 millimeters) in the fine grinding bin is reduced to a value approximating or slightly smaller than the size of the grate hole due to abrasion, the grate hole of the discharge grate plate is clogged. The double-layer partition is characterized in that the discharge grate plate is a punched plate, the punched plate is formed in a manner that uniformly distributed strip-shaped grate holes are punched in a steel plate, and the widths of the strip-shaped grate holes range from 3 millimeters to 6 millimeters. The double-layer partition has the effects that during the normal replacement cycle of the steel-section grinding body, the grate holes in the discharge grate plate can be prevented from being clogged by the steel-section grinding body which is thinner due to abrasion; meanwhile, airflow can normally pass through the dry ball grinder, so as to avoid the phenomenon of coarse grinding.
