Advantages of Ultra-fine Grinding Mill in Processing Quartz

High Grinding Efficiency

Adopting the "material layer grinding" principle, the grinding roller and grinding ring work closely together to efficiently squeeze and shear materials. The energy utilization rate is higher than that of traditional impact crushing, and the energy consumption per unit product is reduced by about 20% - 30% compared with other similar equipment.

Wide Range of Fineness

By adjusting the rotation speed of the classifier, products with fineness from 80 mesh to 800 mesh or even finer can be produced, meeting the diverse needs of different industries for the fineness of quartz powder.

High System Integration

Integrating crushing, grinding, classification, and collection, it has a compact layout and high automation degree. The floor area is reduced by about 30% - 50% compared with traditional equipment, saving site rental costs and improving production efficiency.

Environmental Protection and Cleanliness

The entire system operates under negative pressure, with little dust leakage. Equipped with an efficient pulse dust collector, the dust emission concentration can be controlled below 30mg/m³, which is much lower than the national standard.

Long Service Life of Wear Parts

Core grinding components such as grinding rollers and grinding rings are made of wear-resistant materials such as high-chromium alloy steel and ceramic materials. Taking high-chromium cast iron as an example, its service life is about 2 - 3 times longer than that of ordinary materials, reducing the number of maintenance and repair costs, and improving the continuity and stability of production.

Process of Processing Quartz with Ultra-fine Grinding Mill

Coarse Crushing

The jaw crusher initially crushes the quartz ore to below 50mm.

Medium Crushing and Cleaning

The cone crusher or impact crusher further performs medium crushing, and at the same time, water washing or flotation is used to remove impurities on the surface of the quartz.

Drying

The dryer removes the moisture of the quartz after water washing, creating conditions for subsequent processing.

Magnetic Separation

The dry magnetic separator initially removes iron to reduce the iron content of the quartz.

Fine Crushing/Grinding

The ultra-fine grinding mill plays a key role, with the grinding roller and grinding ring rolling and crushing the quartz particles.

Classification

The classifier accurately classifies the crushed materials. Qualified fine powder enters the collection system, and coarse powder returns for re-grinding.

Collection

Cyclone separators and pulse bag filters collect the finished quartz powder to ensure that the gas is discharged up to the standard.

Packaging

The collected finished powder is packaged and then put on the market.

Key Points in Processing Quartz with Ultra-fine Grinding Mill

Equipment Wear

The high hardness of quartz causes rapid wear of processing equipment, and the service life of grinding rollers and grinding rings may be only one-third to one-half of that when processing ordinary materials. Selecting wear-resistant materials is crucial. For example, grinding rollers and grinding rings are made of high-chromium cast iron or ceramic composite materials, and the inner lining of pipelines and fan impellers is made of wear-resistant ceramics or wear-resistant steel plates.

Product Purity

Many fields have strict requirements on impurities such as iron content in quartz powder, and equipment wear will introduce iron pollution. In terms of material upgrading, ceramic or high molecular polyethylene linings are used in parts in contact with materials such as the grinding chamber, classification wheel, and pipeline; in terms of magnetic separation and iron removal, multiple high-intensity magnetic separation processes are carried out on raw materials and products before and after crushing.

Energy Consumption Issue

Quartz has high hardness, making grinding difficult and energy consumption high. In some large-scale enterprises, energy consumption costs account for 30% - 40% of the total cost. Multi-stage crushing can reduce the load of the mill and lower energy consumption. For example, after optimization in a project, the feed particle size is reduced from 50mm to 15mm, the energy consumption of the ring roller mill is reduced by about 25%, and the production efficiency is increased by 20%; optimizing the air system can improve classification efficiency and avoid energy waste, which can reduce energy consumption by 10% - 15% in actual production.

Summary

The ultra-fine grinding mill has many advantages in processing quartz. The process covers multiple links. The key points in processing lie in paying attention to equipment wear, ensuring product purity, and solving energy consumption problems.
