Background

The crusher is a crushing machine in which the content of the particles with the particle size of more than three millimeters in the discharged materials accounts for more than 50 percent of the total discharged amount. Crushing operations are usually divided into coarse crushing, medium crushing and fine crushing according to the size of the feeding and discharging particle sizes. And (4) classification: the commonly used crushing machines include jaw crushers, gyratory crushers, cone crushers, roll crushers, hammer crushers, impact crushers, and the like.

The hammer crusher is a crushing machine which utilizes the high-speed impact action of a hammer head to carry out medium crushing and fine crushing operation on materials. The hammer is hinged on the rotor rotating at high speed, and the lower part of the machine body is provided with a grate bar to control the granularity of discharged materials. The material fed into the crusher is firstly impacted by the hammer head moving at high speed to be crushed for the first time, and simultaneously obtains kinetic energy, and the kinetic energy flies to the crushing plate on the inner wall of the shell at high speed to be crushed again. The material smaller than the gap of the grate bar is discharged out of the machine, and the material block larger than the gap of the grate bar is impacted and ground by the hammer on the grate bar again until the material block is smaller than the gap of the grate bar and then discharged.

The hammer crusher has the advantages of large crushing ratio, uniform discharge granularity, less over-crushed materials, low energy consumption and the like. But the application of the crushing of hard materials is limited because the hammer head is worn quickly; in addition, the grate bars are not suitable for crushing materials with high humidity and clay because of the fear of blockage. Such crushers are commonly used to crush brittle materials of sub-hardness, such as limestone, shale, coal, gypsum, chalk, etc. A ring-type coal crusher with a hammer head of the hammer crusher replaced by a steel ring is a modification of the hammer crusher. It utilizes the combined action of high-speed impact and low-speed rolling to break material, so that it can obtain thinner product, mainly can be used for breaking coal for power plant, but also can be used for breaking gypsum, salt chemical raw material and some medium-hard materials.

In the production process of preparing cellulose, raw materials need to be sent into a crusher for mechanical crushing, the prior art generally uses a hammer to crush the cellulose, but the hammer crushing equipment has limitations, the production energy consumption is large, the efficiency of preparing the cellulose is low, and the fineness and the viscosity of products cannot meet the production requirements.
