Problems solved by technology

The partition plate in the prior art generally forms a partition after fixing a plurality of grate plates around a central plate at the working position to separate the grinding body. When multiple grate plates are fixed around the central plate, the gap between adjacent grate plates The gaps are spliced ​​together, and when the ball mill is working, the grinding body collides with the partition plate. After a long time of use, gaps are prone to appear at the joints of adjacent grate

Abstract

The invention discloses a novel UHPC (Ultra High Performance Concrete) partition plate, comprising six grid plates and a center plate. The six grid plates are spliced into a 360-degree circular plate around the center plate; each grid plate is provided with a plurality of first filter grooves; the center plate is provided with a plurality of second filter grooves; and one end of each grid plate is fixedly connected with a clamping plate. The novel UHPC partition plate has the advantages that in the working process of the novel UHPC partition plate, every two adjacent grid plates are stably connected, gaps are not prone to occurring at the connecting positions of the grid plates, and the situation that after gaps are generated between the adjacent grid plates, cracks are generated due to external force, and consequently use of the partition plate is affected is avoided; meanwhile, in the working process of the partition plate, the stability of connection between the center plate and the grid plates is high; and when a ball mill works and a grinding body collides with the partition plate, the center plate is not prone to being separated from the partition plate, and the situation that normal use of the ball mill is affected due to leakage holes in the partition plate is avoided.

Description

technical field [0001] The invention relates to the technical field of ball mill accessories, in particular to a novel ultra-high-strength concrete UHPC compartment board. Background technique [0002] Ball mill is the key equipment for crushing materials after being crushed. It is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation, glass ceramics and other production industries. Dry or wet grinding with other grindable materials. After the materials are coarsely ground in the first chamber of the ball mill, they enter the second chamber through the partition board. The chamber is inlaid with a flat liner and contains steel balls. The material is further ground, and the powder is discharged through the discharge grate plate to complete the grinding operation. The partition plate in the prior art generally forms a partition after fixing a plurality of grate plates around a ce...
