Refined treatment method for chemical raw materials

Abstract

The invention belongs to the technical field of preparation of chemical raw materials, and particularly relates to a refined treatment method for chemical raw materials. The method adopts the following grinding equipment. The grinding equipment comprises a grinding barrel, a grinding motor, a sliding unit, a grinding unit and a returning unit, wherein the grinding barrel is cylindrical, the central axis of the grinding barrel is vertically placed, a feeding inlet is formed in the top of the grinding barrel, and a material taking port is formed in the side wall of the bottom of the grinding barrel; the grinding motor is mounted on the top of the grinding barrel; the sliding unit is arranged in the inner wall of the grinding barrel for being matched with the grinding unit to grind the chemical raw materials; the grinding unit and the returning unit are located in the grinding barrel, the grinding unit is located above the returning unit, the grinding unit is used for grinding the chemical raw materials and the returning unit is used for recovering chemical powder; and the chemical raw materials enter the grinding barrel through the feeding inlet, and under the action of the sliding unit, the grinding unit and the returning unit matched one another, the device cuts, grinds and recovers the chemical raw materials, so that the grinding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of chemical raw materials, and in particular relates to a refined treatment method for chemical raw materials. Background technique [0002] The relationship between human beings and chemical industry is very close, and it has spread to all aspects of life. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing and transportation to spiritual life such as culture, art and entertainment, chemical products are required to serve them. Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. [0003] At present, most of the chemical raw material grinding methods used in the market are raw material mills. The raw material mill has a single-chamber structure, and the inner lining plate of ...

Problems solved by technology

The raw material mill usually adopts the edge transmission mode. The material to be ground enters the raw material mill continuously and evenly through the feeder, and the motor drives the mill cylinder to rotate through the reducer. The material first spirals into the first grinding chamber along the hollow shaft. , the steel ball medium and the material in the mill are subjected to the friction and centrifugal force generated by the rotation of the cylinder, and the material is brought to a certain height under the action of the centrifugal force, and then it is thrown and dropped in the form of a material curtain, and then it is hit and ground by the steel ball , the crushed finished products are discharged from the mill to select qualified materials through the sorting equipment, and the unqualified materials in the circulating grinding system continue to return to the mill to be hit and ground by the grinding body until the fineness is qualified, but the general raw materials The vertical mill structure includes grinding discs, grinding rollers, a center frame and a hydraulic tension system. The composition structure is very complicated, and the size is relatively large, which is not convenient for transportation.
