Alumina Ceramics:
The working principle of alumina rotary kiln. The calcined alumina powder is input into the tail end of the kiln body with a certain inclination and slow rotation (the high end of the cylinder), and the kiln head cover from the kiln head (lower end of the cylinder) is sprayed with a spray gun The clean flame is sprayed into the kiln, and the alumina powder is dehydrated and calcined. After being dehydrated at a high temperature of about 1650 ° C, the calcined alumina powder is tumbling in the circumferential direction and in the axial direction by means of the inclined rotary kiln body. Move from high-end to low-end, gradually complete the dehydration and calcination process, enter the cooling machine through the flap discharge valve in the lower part of the kiln cover, and the cooled and sieved material is the high-temperature alumina finished product. Calcined alumina rotary kiln production line equipment is popular in Henan manufacturers. The powder used for metal mirror polishing is classified into alumina and silica. Silica is generally used for the mirror treatment of aluminum alloys due to its low Mohs hardness and low particle size, and it does not provide sufficient cutting force for cousin treatment such as stainless steel or iron. Therefore, the mirror surface treatment of the metal surface is mainly based on alumina.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
