The type of cryolite

The ratio of the crystal of cryolite to the molecular ratio of sodium fluoride and aluminum fluoride can be divided into high polymer than cryolite and low molecular ratio cryolite.
Most of the domestic electrolytic aluminum smelters use low molecular ratios of 1.8~2.2 to electrolyte electrolyte for aluminum electrolysis.
Due to the use of polymer than cryolite in environmental protection and economic benefits, etc are better than that of low molecular cryolite, so China's electrolytic aluminium plant widely used polymer cryolite aluminium electrolytic electrolyte.
Cryolite can be divided into sand crystal, granular cryolite and powdery cryolite according to its physical properties.
It is characterized by low melting point and fast melting speed, which can shorten the time of entering normal working state.
The molecular ratio can be adjusted in a larger scope, and it can adapt to different requirements of the molecular ratio of cryolite in different periods of electrolysis.
Low water content, low fluorine loss;
The granule shape, good fluidity, good for conveying;
The raw materials are readily available and the production cost is low.
The characteristics of granular cryolite are: good fluidity, dust pollution, suitable for mechanization;
The high yield in electrolytic production can reduce the cost of electrolytic aluminum.
The molecular ratio is between 2.5 and 3.0, which is especially suitable for the opening of electrolytic aluminum.

Most of the particles are 1~10mm.
