The invention provides a fine grinding device for materials. The fine grinding device comprises a crushing box, a coarse grinding box and a fine grinding box, wherein a feeding port is arranged abovethe crushing box, and crushing rollers are arranged in the crushing box; material guide plates are arranged in the coarse grinding box, and coarse grinding rollers are arranged below the material guide plates; a grinding plate is arranged in the fine grinding box, a motor is fixedly installed on the left side face of the coarse grinding box, the right side of the motor is movably connected with adriven rod and a grinding roller through a driving rod, and the external surface of the grinding roller is fixedly connected with a grinding wheel; a filter screen is arranged on the right side of thegrinding plate, and an induced draught fan is arranged on the surface of the right side of the filter screen; and a material collecting hopper and a discharging port are arranged below the grinding plate. The fine grinding device overcomes the shortcomings of the prior art and is reasonable in design and compact in structure, the crushing rollers can play a primary role in crushing the materials,the materials can be preliminarily ground through the coarse grinding rollers, and the materials can be finely ground by the grinding roller and the grinding wheel.
Description
technical field [0001] The invention relates to the technical field of material fine grinding, in particular to a material fine grinding device. Background technique [0002] Mining, cement, chemical and building material industries all require powders of different particle sizes, which usually need to be crushed and finely ground; 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 consists of a cylinder, steel balls, and a bracket. This ball mill mainly completes the powder by continuously squeezing the powder between the steel balls and between the steel ball and the cylinder. Grinding; for larger agglomerated materials, the device will be damaged during fine grinding, and the fine grinding efficiency is not high. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present inventi...
