Abstract

The invention provides a material crushing and fine grinding device. The device comprises a crushing box and a grinding box; a feed port is formed in the right side of the upper surface of the crushing box; a rotating roller is arranged in middle in the crushing box; the outer surface of the rotating roller is fixedly connected with an impact hammer; a first impact plate and a second impact plateare arranged on the upper side in the crushing box; a fixed block is arranged on the left side in the grinding box; the right side of the fixed block is fixedly connected with a grinding plate througha buffer spring; grinding rollers are uniformly and movably connected to the right side in the grinding box; grinding wheels are arranged on the outer surfaces of the grinding rollers; a filter screen is arranged on the lower side in the grinding box; and a discharge port is fixedly connected under the filter screen. The device overcomes the defects in the prior art, and is reasonable in design and compact in structure; through coaction between the impact hammer and the first impact plate, the second impact plate, materials are crushed through continuous collision; and through the effect of movable connection between the grinding wheels and the grinding plate, the materials are finely grinded.

Description

Technical field [0001] The invention relates to the technical field of material crushing, in particular to a material crushing and fine grinding device. Background technique [0002] The mining, cement, chemical and building materials industries all require powders of different particle sizes, which usually undergo crushing and fine grinding; therefore, crushing and fine grinding devices are required to complete this process. [0003] At present, the most commonly used fine grinding device is a ball mill, which is composed of a cylinder, a steel ball, and a support. This kind of ball mill mainly completes the powder through the continuous squeezing and grinding of the powder between the steel balls and between the steel ball and the cylinder. For larger agglomerated materials, the device will be damaged during fine grinding, and the fine grinding efficiency is not high. Summary of the invention [0004] (1) Technical problems solved [0005] In view of the shortcomings of the prior ...
