Grate plate used for coarse grinding chamber of cement ball mill

Abstract

The invention provides a grate plate used for a coarse grinding chamber of a cement ball mill. The grate plate includes a chamber-separation grate plate body mounted on a grate plate bracket, the chamber-separation grate plate body is formed through splicing of a plurality of grate-plate single bodies of a fan-shaped structure, and a grate seam and an installation hole are formed in each single grate-plate single body. Each grate-plate single body is of an integral structure, the inner arc surfaces of the grate-plate single bodies are provided with ball blocking plates, the inner arc surface of each grate-plate single body is provided with a rectangular groove, and excircles of the ball blocking plates are uniformly provided with a plurality of clamping blocks matched with the rectangulargrooves. The ball blocking plates adopt an integral structure, the annularly arranged clamping blocks are welded in the rectangular grooves, the phenomenon that grinding balls in the coarse grinding chamber can constantly hit against the chamber-separation grate plate body and the ball blocking plates welded on the grate plate bracket and the ball blocking plates can fall after long-time hitting of the grinding balls is avoided, the normal operation of equipment is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cement production and processing equipment, in particular to a grate plate for a coarse grinding bin of a cement ball mill. Background technique [0002] At present, ball mills with drying and grinding functions are widely used in the cement industry, and the operating rate of this equipment directly affects the quality and output of clinker fired in cement rotary kilns. The cylinder body of the ball mill is composed of three chambers: drying chamber, coarse grinding chamber and fine grinding chamber. The ball baffle is separated, the compartment grate plate is fixed on the grate plate support by bolts, and the grate plate support is fixed on the inside of the bin body by bolts. The ball baffle with ring structure is welded on the grate plate bracket and is located at the center of the grate plate in the compartment, which can prevent the grinding balls from entering the drying chamber from the coarse gr...
