Autoclave is a container that undergoes physical or chemical reactions, with the standard code GB/T 32708-2016. 
The classification and material selection of reaction kettles can be divided into carbon steel reaction kettles, stainless steel reaction kettles, and glass lined reaction kettles (enamel reaction kettles), which are widely used in production users such as petroleum, chemical, rubber, pesticides, dyes, pharmaceuticals, food, and various research and experimental projects. The working principle of a reaction kettle is to stir the reactants through a motor driven stirring shaft to fully react and obtain the required substances.
Crushing machine is a machine that crushes large-sized solid raw materials to the required size. Crushers are widely used in various sectors such as mining, smelting, building materials, highways, railways, water conservancy, and chemical industry.  Commonly used crushing machinery includes jaw crusher, impact crusher, air separation crusher, hammer crusher, impact crusher, roller crusher, composite crusher, etc. The jaw crusher has the characteristics of large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance, and economic operating costs. The impact crusher can handle materials with a side length of 100-500 millimeters or less, and its compressive strength can reach up to 350 megapascals. It has the advantages of high crushing ratio and cubic particles after crushing; The impact crusher is suitable for crushing medium to hard materials, with the advantages of large production capacity and small discharge particle size.
Mechanical stirrer, which relies on the rotation of the stirrer in the stirring tank to stir the liquid, is a commonly used method for dispersing gas, liquid, or solid particles into the liquid in chemical production.
The commonly used stirring tank in industry is a cylindrical container, sometimes equipped with a jacket outside the tank or heat exchange devices such as coils inside the tank to heat or cool the materials inside. Several vertical baffles are often installed on the inner side of the groove wall to eliminate the liquid level depression vortex caused by high-speed rotation of the liquid, and to enhance the turbulence of the liquid flow and enhance the mixing effect. Agitators are usually installed at the end of the rotating shaft and are usually inserted into the liquid layer from the top of the tank (large mixing tanks also have a bottom extending type). Sometimes a cylindrical guide cylinder is set around the agitator to promote liquid circulation and eliminate short circuit and dead zone. For tanks with a large aspect ratio, in order to ensure good mixing of the entire tank liquid, several sets of agitators can be installed on the same shaft. The agitator shaft is driven by an electric motor through a reducer. If there are changes in the material properties during the process, it is best to use multi-stage or stepless speed changes. Another method of driving the stirrer is magnetic drive, which applies a rotating magnetic field outside the tank to rotate the magnetic components inside the tank, driving the stirrer to stir the liquid. The use of magnetic transmission can avoid high-pressure dynamic sealing, and the air tightness is very good.
