SOLUTION

The core technology and equipment of Silicon Sand Grinding Mill mainly revolve around the grinding system, which aims to grind silicon blocks (usually 25-80mm) to specific particle sizes (usually 80-400 μ m) to meet industrial application needs, such as methyl monomer synthesis, casting, refractory materials and other fields. Below is an introduction to VEST’s core technology and equipment for Silicon Sand Grinding Mill:

1. Crushing equipment

The initial stage of a Silicon Sand Grinding Mill usually requires crushing equipment to crush large pieces of silica sand to a size suitable for grinding. Common crushing equipment includes:

Jaw crusher: used for coarse crushing, capable of processing materials with larger particle sizes, suitable for preliminary crushing of silica sand.

Cone crusher: used for secondary crushing, capable of producing a more uniform particle size distribution, suitable for fine crushing of silica sand.

Counterattack crusher: With high crushing efficiency and good particle size distribution, it is suitable for the medium and fine crushing of silica sand.

The selection of these crushing equipment needs to be configured according to the hardness, particle size, and production requirements of the silica sand.

2. Grinding equipment

Grinding equipment is the core of Silicon Sand Grinding Mill, and its main function is to grind silicon blocks to the required particle size. Common grinding equipment includes:

Vertical Roller Mill: With a simple process, good sealing, high dust collection efficiency, low noise, and low energy consumption, it is the preferred equipment for grinding silicon powder. The combination of raw material drying and grinding process can further save energy, and the grinding force can reach 20-200 mesh and sand powder below 3 millimeters.

Raymond mill: It has the advantages of stable performance, simple operation, large processing capacity, and adjustable product particle size. The range of grinding force is relatively wide, but the process flow is complex and the efficiency is relatively low.

Ball mill: VEST’s ball mill has the advantages of high crushing ratio, simple structure, and mature technology. Through friction and impact, silicon powder can be ground to the desired particle size.

3. Grading equipment

The grading equipment is used to separate the ground silicon powder according to particle size, ensuring that the particle size distribution of the final product meets the requirements. Common grading devices include:

Powder Classifier: used to classify the ground silicon powder according to particle size, ensuring that the particle size distribution of the final product meets the requirements.

4. Drying equipment

Drying equipment is used to remove moisture from ground silicon powder, ensuring the final product is in a dry state. Common drying equipment includes:

Drying machine: used for drying cleaned silica sand. Although it can also be omitted, the silica sand dried by the drying machine has a more uniform color compared to the silica sand dried by air.

5. Auxiliary equipment

In addition to the core equipment, the Silicon Sand Grinding Mill also requires some auxiliary equipment to ensure the smooth progress of the production process, including:

Feeding equipment: such as vibrating feeders, electromagnetic vibrating feeders, etc., used to evenly feed the crushed silica sand into the grinding equipment.

Conveyor equipment: such as conveyors, screening machines, etc., used to transport the ground silicon powder to subsequent grading and drying equipment.

Dust removal equipment: such as cyclone powder collectors, washing dust removal equipment, etc., used to remove dust generated during the grinding process and ensure a clean production environment.

Summarize

The core technology and equipment of Silicon Sand Grinding Mill mainly include crushing equipment, grinding equipment, grading equipment, drying equipment, and auxiliary equipment. Among them, the grinding equipment is the core, which determines the particle size and particle size composition of silicon powder. In the design and operation of Silicon Sand Grinding Mill processing, VEST’s equipment pays more attention to automation, environmental protection, and energy conservation to meet various production needs for high-purity and high particle size silicon powder.Welcome to contact us for relevant information.
