Material Characteristics:
Alumina is a compound with a high hardness of 2054 and a boiling point of 2980, ionic crystals that can be ionized at high temperatures, and are often used in the manufacture of refractory materials.
Applications:
It is used as a dehydration agent for analysis, an adsorbent, an organic reaction catalyst, an abrasive, a polishing agent, a raw material for smelting aluminum, and a refractory material.
Equipment selection:
It is a white solid that is insoluble in water, odorless, tasteless, hard, easy to absorb moisture without deliquescent (burned without moisture absorption). Alumina is a typical oxide, (corundum is a hexagonal dense accumulation, is an inert compound, insoluble in acid and alkali corrosion resistance [1]) soluble in inorganic acids and alkaline solutions, almost insoluble in water and non-sexual relative density (d204) 40；Melting point 2050, according to the characteristics of alumina, ZJ-QLM and ZJ-C series can be selected.
How ZJ-C works:
The material is transported to the main engine crushing chamber by the feeding device, and the material is crushed by impact, collision, friction, shearing and extrusion between the material and the high-speed rotary device and particles. The crushed material realizes the separation of coarse and fine powder through the grading wheel, the coarse powder flows into the crushing chamber and grinds again, and the purified gas is discharged by the induced draft fan.
Equipment features:
1. Low energy consumption: it integrates centrifugal crushing, impact crushing and extrusion crushing, and saves up to 40 50% energy compared with other types of mechanical crushers.
2. High fineness: equipped with self-splitting grading system, product fineness of 2500 mesh.
3. Large feeding range: the feeding particle size is 50mm, and the material only needs to be coarse.
4. Low wear: the crushed part of the wearing parts is made of composite * new material, which has a long service life and is used when processing materials with Mohs hardness of 5.
5. Strong mechanical stability: long-term 24-hour non-stop production.
6. Full function:
It can crush needle-like materials to achieve a finished product length diameter ratio of 15:1;
There is no temperature rise in the crushing process, which is suitable for the crushing of heat-sensitive materials
It can break up the sintered agglomerated ultrafine materials, and the particle size recovery rate is up to 100%;
It has the function of particles, which can effectively improve the bulk density.
Materials that can crush fibrous tissues;
It can crush materials with high moisture content and has the function of drying
It can crush materials with strong viscosity.
7. Negative pressure production, no dust pollution, excellent environment.
8. High degree of automation, strong stability and easy operation.
9. The whole system adopts automatic control, which can realize one-button start and stop, simple and convenient operation, and can be connected with the central control to achieve remote control.
