Material crushing and grinding device

Abstract

The invention discloses a material crushing and grinding device which comprises a machine shell. A crushing chamber and a grinding chamber are arranged in the machine shell. A first motor is mounted above the crushing chamber. The output end of the first motor is connected with a stirring rod. The outer side of the stirring rod is fixedly connected with stirring blades. Cutting mechanisms are arranged between the stirring blades and mounted on the outer side of the stirring rod. A spiral rod is fixedly connected to the bottom end of the stirring rod. Nail plates are connected to the two sidesof the inner wall of the crushing chamber. Open grooves are formed in the two sides of the grinding chamber. Under drive of a drive device, a grinding roller and grinding plates in the grinding chamber grind crushed materials; and through the arrangement of air cylinders, supporting plates can ascend and descend, meanwhile, the grinding roller is driven to ascend and descend, the distance betweenthe grinding roller and the grinding plates is adjusted, and therefore the size of particles in the grinding process of the materials is adjusted, and particles of different required diameters can beground out during grinding production.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a material crushing and grinding device. Background technique [0002] A pulverizer is a machine that pulverizes large-sized solid raw materials to the required size. The pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of the pulverizer in the form of high-speed impact. Using wind energy to form powder at one time, the traditional screening procedure is cancelled. Mainly used in mining, building materials and other industries. According to the size of the crushed material or crushed material, the crusher can be divided into coarse crusher, crusher and ultrafine crusher. There are four kinds of external forces applied to the solid in the pulverization process: shearing, impacting, rolling and grinding. Shearing is mainly used in coarse crushing and crushing operations, suitable for the crushing o...

Problems solved by technology

[0003] Some materials need to be polished after being cut and crushed. It is troublesome to divide the cutting and crushing into two steps for two processing, and the particle size of the material is difficult to control. Therefore, a material crushing and grinding device is provided to solve the above problems. question is very necessary
