Alumina Grinding Media
Product Introduction
Alumina grinding media refers to the use of bauxite, roll powder, alumina and high temperature calcined α alumina powder as raw materials, and need to go through the mixing, grinding, grinding, molding, drying, sintering process. It is mainly used for grinding media and is widely used, and can also be divided into aluminum ball, high aluminum ball and high aluminum ball according to the different content of alumina.
Advantages
Alumina grinding ball because of its low price is accepted by most ceramics factories for the grinding of ceramic billets. In addition, due to its high strength, high hardness, high wear resistance, small size, high temperature resistance, corrosion resistance performance is widely used in different types of ceramics, enamel, glass, chemical and other factories of thick hard materials and deep addition.
Application
Application in cement factory
Various chutes
Ore crushing system, raw material grinding system, cement grinding system, all kinds of chute, hopper, daily processing capacity is large, material hardness is high, equipment wear serious. Previously, in the absence of any anti-wear measures, 10mm steel often wear within a week; Use 30mm manganese steel lining board, a few months wear. Frequent equipment wear not only increases the maintenance burden, but also seriously affects the normal operation of the equipment. Site dust pollution is serious, the staff suffered serious injuries.
V-select shell and broken plate
Pipe lining of various shapes
It is very effective to use toughened alumina wear-resistant ceramics instead of wear-resistant steel plates. Alumina wear-resistant ceramics can also be made into a set of broken plates, not only greatly improve the wear resistance, but also very convenient replacement.
Fan impeller
In the new dry process production line, the powder transport is mainly powered by the fan. The high speed rotation of the fan causes the relative movement of the dust-containing two-phase particle air flow with the blade, which makes the impeller wear seriously. After using alumina wear-resistant ceramics, wear resistance increases and service life increases.
Application in power plants
Conveying line lining
The wear of pulverized coal grinding system in coal-fired power plant is mainly caused by pulverized coal collision and impact wear. Similar to the air pipe elbow of the powder selection system in cement factory, the high-speed pulverized coal air flow to the pulverizing equipment of the coal mill outlet, the inlet and outlet of the coarse and fine powder separator, the primary air pipe elbow. In the grinding system, glue and alumina wear-resistant ceramic plate are usually pasted on the steel plate after processing.
