Introduction to the main production equipment of modified silica micro powder

Modified silicon micro powder is made of natural quartz or fused silica (natural quartz is amorphous SiO2 after high temperature melting and cooling) through crushing, purification, grinding, grading and other processes.

Powder quantitative conveying system, gas quantity control and mixing device, gas fuel high-temperature flame spray gun, cooling and recovery device.

The powder quantitative conveying system uses pneumatic conveying to continuously and uniformly transport the powder to be processed into spherical silicon micro powder according to the specified feeding amount

Sent into a high-temperature flame.

The gas quantity control and mixing device can adjust and control the gas quantity and combustion supporting gas quantity according to the flame temperature, flame length, and stiffness, and fully mix the gas with the combustion supporting gas before sending it to the high-temperature flame spray gun.

The gas fuel high-temperature flame spray gun sprays a mixture of fuel gas (mixed with combustion supporting gas) and non spherical silicon micro powder material simultaneously. After ignition, a high-temperature flame is generated, melting and dispersing the silicon micro powder into spherical silicon micro powder.

The cooling and recycling device rapidly cools the melted and dispersed high-temperature spherical silicon micro powder to avoid crystallization, and recovers the cooled spherical silicon micro powder in the collector.
