Vertical Roller Mill for Calcite —— The preferred equipment for processing ultrafine calcite powder

1. Product Introduction

Vertical Roller Mill is an advanced powder processing equipment integrating crushing, grinding, drying, grading and conveying, which is widely used in the field of deep processing of non-metallic minerals. Especially in the preparation of ultrafine calcite powder, Vertical Roller Mill has become one of the core equipment in the heavy calcium industry with its high efficiency, energy saving and intelligent characteristics.
Compared with traditional Raymond mill and ball mill, vertical mill not only performs well in powder quality and energy consumption control, but also can achieve higher output and lower operation and maintenance costs. It is an important technical equipment to promote the upgrading of calcium carbonate industry.

2. Equipment structure and working principle

Vertical Roller Mill is mainly composed of the following parts:
Mainframe (grinding roller, grinding disc, main shaft), powder selector, fan, dust removal system, transmission device, lubrication system, electronic control system, etc.
Brief description of the working process:
1. After being crushed, the calcite ore is sent to the silo by the elevator;
2. It enters the grinding chamber through the feeder and falls into the rotating grinding disc;
3. Multiple grinding rollers press against the grinding disc under the action of centrifugal force, repeatedly crushing the material into powder;
4. The high-speed airflow brings the powder into the powder selector for classification, and the qualified powder enters the collection system;
5. The coarse powder falls back and is re-ground to achieve an efficient closed-loop circulation system.

3. Applicable materials and application fields

Applicable materials:
• Calcite, limestone, marble, dolomite
• Talc, barite, bentonite, kaolin
• Quartz, fluorite, gypsum, coal powder, graphite, etc.
Typical application industries:
• Heavy calcium powder production (GCC)
• Filler-grade calcium carbonate (rubber, plastic, coating, papermaking)
• Food and pharmaceutical grade fine powder (requires ultra-clean system)
• Cement, metallurgy, building materials, refractory materials industry
