About Silicon Carbide
Silicon carbide, is a kind of inorganic substance, chemical formula is SiC, is the quartz sand, petroleum coke (or coal coke), wood chips (the production of green silicon carbide need to add salt) and other raw materials through the resistance furnace high temperature smelting.Silicon carbide powder fineness uniformity, good quality, high sorting accuracy, due to its own chemical properties, high thermal conductivity, thermal expansion coefficient is small, good wear resistance, there are four main application areas, functional ceramics, refractory materials, abrasives and metallurgical raw materials.
What does silicon carbide do
The third generation of semiconductor high-power power electronic devices represented by SIC is one of the fastest growing power semiconductor devices in the field of power electronics. As a typical representative of the third generation of semiconductor materials, silicon carbide is also one of the most mature and widely used semiconductor materials in crystal production technology and device manufacturing level, and has formed a global material, device and application industry chain. It is an ideal semiconductor material for high temperature, high frequency, radiation resistant and high power applications.Because silicon carbide devices can greatly reduce the energy consumption of electronic equipment, it is often used in lighting, all kinds of motor systems, new energy vehicles and other fields. In addition to being used in household appliances, semiconductor silicon carbide materials play a superior role in energy saving and environmental protection in the field of power electronics such as high-speed rail, solar energy, wind energy, electric energy, and power transmission.
With its excellent physical and chemical properties, silicon carbide has been widely used and rapidly occupied the semiconductor material market. With the continuous decline in production costs, the excellent performance of silicon carbide in the power device industry to achieve the gradual replacement of silicon semiconductor.
Silicon carbide production process
The hardness of silicon carbide is very high, the Mohs hardness is 9.3~9.5, and it is hexagonal crystal. For this property, the choice of Jaw crusher, Raymond mill and other powder production equipment is more suitable, in the additional machinery, we match you with bucket elevator, powder separator, dust collector and other equipment to form a production line.
Specific production process is：
1.The use of forklift or manual silicon carbide into the jaw crusher, grinding to enter the mill particle size, adjust the discharge port, easy to smooth discharge. 2.The small pieces of pulverized silicon carbide are sent to the silo by the bucket elevator, and then evenly quantified into the Raymond mill by the vibration feeder for grinding in the grinding room.
3.The pulverized silicon carbide powder is graded by the separator, and the unqualified powder is graded by the separator and returned to the host machine for re-grinding.
4.The silicon carbide fine powder that meets the requirements is separated and collected by the air flow through the pipe into the dust collector, and the collected finished powder is sent by the conveying device through the discharge port into the finished product warehouse, and then unified packaging.
Mill introduction
Jaw crusher
Output sive : 65~160mmFeed sive : 480mm
Capacity : 1~140 t/h
Equipment advantage :
1.Low noise and less dust.2.The crushing ratio is large, and the product size is uniform.
3.The structure is simple, the work is reliable, and the operating cost is low.
4.The lubrication system is safe and reliable, the replacement of parts is convenient, and the equipment maintenance is simple.
5.The crushing cavity is deep and there is no dead zone, which improves the feeding capacity and output.
6.Equipment energy saving: single machine energy saving is 15%-30%, system energy saving is more than doubled.
7.The adjustment range of the discharge opening is large, which can meet the requirements of different users.
Raymond mill
Capacity : 0.2-50 t/hMax feeding size : 35mm
Processing ability : 0.2-50 t/h
Equipment advantage :
1.The grinding force is large. The grinding roller assembly of the Raymond grinding mill adopts a high-pressure spring device to increase the grinding force. The grinding force of each grinding roller assembly can be increased by 500Kg on the original basis, which greatly improves the milling efficiency.2.The grinding area is large, and the grinding height of the grinding roller and grinding ring is increased from 160mm to 200mm.
3.High classification accuracy.
4.The main engine adopts a buffer device, and the structure of the main casing is optimized to ensure stable operation and low noise.
5.The main engine and analysis machine adopt quick-change pressing device, which is convenient for maintenance.
6.The residual wind is collected by cloth bags, and there is no dust pollution.
