Vertical roller mill in green silicon carbide production process

Vertical roller mill are a key component in the production of green silicon carbide (SiC). Vertical roller mill are used to grind the raw materials, which are typically silica sand and coke, into a fine powder. The powder is then used to produce green SiC, which is a precursor to sintered SiC.

Vertical roller mill have several advantages over other types of grinding mills for green SiC production. First, they are more efficient, requiring less energy to grind the same amount of material. Second, they produce a finer powder, which is important for the subsequent sintering process. Third, they are more versatile, and can be used to grind a wider range of materials.

The Vertical roller mill grinding process for green SiC production typically involves the following steps:

1. The raw materials are preheated to a temperature of around 1,000 degrees Celsius. This helps to break down the silica sand and coke into smaller particles.
2. The preheated materials are fed into the Vertical roller mill. The Vertical roller mill is a cylindrical chamber with two or more rotating rollers. The rollers grind the materials as they pass between them.
3. The ground materials are then discharged from the Vertical roller mill. The ground powder is typically collected in a cyclone separator.

The size of the Vertical roller mill used in green SiC production depends on the desired capacity of the plant. Smaller plants may use a Vertical roller mill with a capacity of 100 to 200 tons per day. Larger plants may use a Vertical roller mill with a capacity of 1,000 tons per day or more.

Vertical roller mill are an essential part of the green SiC production process. They provide a reliable and efficient way to grind the raw materials into a fine powder that is suitable for the subsequent sintering process.
