Ultra Fine Vertical Roller Mill Overview

Ultra fine vertical roller mill not only can effectively refine the material particles, but also integrates the functions of crushing and grading, which can greatly improve the production efficiency and product fineness. The innovative design of ultra-fine vertical roller mill makes it able to replace the traditional Raymond mill, which is suitable for some industries that require high precision crushing.

Working Principle of Ultra Fine Vertical Roller Mill

Combines the action of several physical forces. After the material enters the crushing chamber through the charging screw, it enters the gap between the grinding rolls and the grinding ring fixed on the grinding roller frame by the pin shaft. Driven by the main shaft, the grinding roller presses towards the grinding ring under the action of centrifugal force and rotates around the pin shaft. At this time, the material is subjected to the strong impact of the rollers and the grinding ring, crushing and grinding, and gradually be crushed into fine particles.

The crushed material is sent into the rising airflow through the dumping disk and enters into the grading room. In the grading room, qualified fine powder enters the product outlet through the turbine rotor, and enters the collection system for collection. And the coarse powder that does not meet the requirements is returned to the crushing room through the airflow, and continue to grind until it meets the requirements. In this way, the ultra-fine vertical roller mill realizes the integrated function of crushing and classifying, which greatly improves the production efficiency.

Features and Advantages of Ultra Fine Vertical Roller Mill

• High-efficiency crushing: the equipment combines the three forces of impact, crushing and grinding, and can quickly crush the material to ultra-fine state, with high crushing efficiency.
• Independent operation: crushing and grading are carried out in separate areas, but can be efficiently completed in the same body. Its structure is compact, reducing the footprint, easy to install and maintain.
• Adjustable fineness: through the adjustment of the gap between the grinding roller and the grinding ring, control the crushing granularity, the product fineness range can be adjusted to adapt to different production needs.
• High classification efficiency: turbine speed is controlled by frequency converter motor to realize stepless speed regulation, which can flexibly adjust the crushing and classification speed according to the production needs. Through the frequency conversion speed control and secondary wind combination adjustment, grading efficiency is significantly improved to ensure that the product size distribution is more uniform.
• Energy saving and consumption reduction: the use of advanced airflow classification technology, reducing the excessive crushing of materials, avoiding energy waste, and improving the overall energy efficiency.

Application Areas of Ultra Fine Vertical Roller Mill

• Mineral processing: used for ultrafine crushing of various ores, such as quartz, feldspar, barite and other minerals, widely used in metallurgy, chemical industry and other industries.
• Chemical raw material crushing: in chemical fertilizer, paint, rubber, plastics and other chemical industries, ultra fine vertical roller mill can be used for all kinds of raw materials ultrafine crushing, to provide high quality powder raw materials.
• Food and pharmaceutical: the equipment can be used for drugs, food additives and other materials crushed, such as ginseng, algae, spices and other natural plant processing, in line with the industry’s high standards for fineness requirements.
• The field of environmental protection: ultra-fine vertical roller mill can also be used for waste, slag and other environmentally friendly materials for the refinement of the processing, which contributes to the recycling of resources and waste minimization.
• Building materials industry: in the production of cement, lime, gypsum and other building materials, ultra-fine vertical roller mill can help reduce energy consumption, while ensuring stable powder quality.

To summarize, ultra fine vertical roller mill has become an indispensable and important equipment in many industries by virtue of its structure and efficient crushing performance. Through its accurate classification and flexible adjustment function, it can meet the market’s strict requirements for fineness and quality, which is an important technological breakthrough in the field of ultrafine crushing.
