Silicon micro powder and micro silicon powder, what kind of substance are they? What is the difference between them? Let’s take a look:

Main ingredient

Silicon micro powder: The main component is silica, containing more than 99% silicon, and the powder has a large particle size of 200 mesh, 600 mesh, 800 mesh etc.

Micro-silica powder: The main component is also silica, but the silicon content is between 80-92%, the fineness is less than 1μm, and the average particle size is from 0.1μm to 0.3μm.

Preparation Process

Silicon micro powder: It is processed by natural quartz or fused silica through multiple processes such as crushing, grinding, flotation, pickling and purification.

Micro-silica powder: A large amount of highly volatile SiO2 and Si gas is produced in the hot-melt furnace of ferrosilicon and industrial silicon smelting, and is rapidly oxidized and condensed and precipitated with air.

Raymond mill

The main purpose

Silicon micro powder: It can be used in the manufacturing of ceramics, silicone rubber, paints etc. It can also be used for insulation casting of ordinary electrical components, plastic packaging materials for electronic components and so on.

Micro-silica powder: It can be used as a blending material in the concrete industry to improve the cohesiveness and bleeding of concrete; adding micro-silica powder to cement can reduce particle friction and improve the processability of cement; The preparation of refractory materials improves performance and durability.

And for silicon micro powder grinding, we recommend you HD series high efficiency Raymond Mill from Guilin Hengda Mining Machinery Co., ltd, the output size is  from 80 to 600 mesh and it has the following features.

HD Series Raymond Mill features:

1.High capacity and low consumption, the output is increased by 20%-30% compared with traditional Raymond machine, impeller type fan is used, which efficiency is higher than straight blade type fan, once oil can be used for 30-45 days;

2.Powder classification accuracy is higher, without coarseness missing, the accuracy is 80-600 mesh, classification efficiency of 99%;

3.Efficient and stable, grinding roller and grinding ring always contact during operation; environmental protection, low vibration, low noise.
