Which Is Better Between Ultrafine Mill And Vertical Roller Mill


Release date: 2021-09-04 17:23:00

Which is better, ultrafine mill or vertical roller mill? Which of ring mill and vertical mill is widely used? Vertical roller mill is a popular product of mine milling equipment in recent two years. It is efficient, energy-saving and green. Ring rolling mill is what we usually call ring roller mill. Because of its price advantage, it is an economic and practical product for processing ultra-fine powder, so it is loved by many enterprises.

 

(1)Comparison of ring mill and vertical mill in appearance

The vertical roller mill is mainly composed of main machine, feeder, classifier, blower, pipeline device, storage hopper, electric control system, collection system, etc. It is mainly vertical and covers only 50% of the ball milling area.

 

The ring rolling mill is mainly composed of main machine, feeder, classifier, blower, pipeline device, storage hopper, electric control system, collection system, etc. the grinding wheel and grinding ring are made of special wear-resistant steel with long service life.

 

(2) Which is convenient to install, ring mill or vertical mill

Both ring mill and vertical mill are installed vertically, with less system equipment, compact structural layout, small floor area, short cycle, convenient installation and low construction cost.

 

(3) Which working principle of ring mill or vertical mill is more energy-saving

The vertical roller mill uses a motor-driven reducer to drive the grinding disc to rotate, and the materials to be ground are sent to the center of the rotating grinding disc by the air lock feeding equipment. Under the action of centrifugal force, the material moves around the grinding plate and enters the grinding roller table. Under the pressure of the grinding roller, the material is crushed by extrusion, grinding and shearing.

 

The materials used in the ring rolling mill are crushed into materials less than 10mm by jaw crusher and lifted to the storage hopper by bucket elevator. Then it is quantitatively sent to the main machine cavity by the feeder for grinding. The grinding roller installed on the rotary table in the main machine cavity rotates around the central axis, and there is a large movable gap between the grinding roller and the grinding roller pin. Under the action of centrifugal force, the grinding roller swings horizontally outward, so that the grinding roller presses the grinding ring, and the grinding roller rotates around the grinding roller pin at the same time. The material passes through the gap between the grinding roller and the grinding ring and achieves the function of crushing and grinding due to the rolling of the grinding roller. The grinding roller is arranged in four layers (hch780 is arranged in three layers). The materials are crushed once through the first layer of grinding roller and grinding ring, and then crushed twice, three times and four times through the second, third and fourth layers. Therefore, the materials are fully crushed and ground to obtain the required product fineness.

 

4Comparison of drying capacity between ring roller mill and vertical mill

When grinding materials with large moisture content, the vertical mill can directly send hot air. These hot air will dry the materials. Materials with moisture below 15% do not need to buy an additional air dryer. The ring roller mill is generally not equipped with a hot air blower for air supply and drying.

 

5Product fineness ring roller mill or vertical mill

The finished product particle size of ring roller mill is 5-45 μ M can be adjusted arbitrarily. The equipment has 1-22t / h and various models can be selected. The product fineness can reach D97 ≤ 5 at one time μ m. The particle size of the finished product of the vertical mill is 22-180 μ M can be adjusted arbitrarily. There are 5-200T / h and various models of the equipment can be selected. If it is an ultra-fine vertical mill, the particle size of the finished product is 3-45 μ m. The equipment has 1-40t / h models to choose from.

 

6Which is more environmentally friendly, ring mill or vertical mill

The vertical mill adopts cyclone dust collector and explosion-proof bag breaking dust collector. The after-sales engineer will select secondary dust collection or single dust collection system for users according to different configuration schemes. The ring roller mill adopts the full pulse dust collection system, and the dust collection rate is as high as 99.9%, which effectively ensures the dust-free operation in the workshop.

HLM vertical roller mill integrates crushing, drying, grinding, grading and conveying. The residence time of materials in the mill is short, it is easy to detect the particle size distribution and chemical composition of products, and the mechanical wear iron contained is easy to be removed. When used for grinding white or transparent materials, the whiteness and purity of the product are high. Fineness of finished product 22-180μM can be adjusted arbitrarily, and various models with a capacity of 5-200T / h can be selected.

 

Guilin Hongcheng mineral powder grinding mill -HLM vertical roller mill

 

Product fineness〗:22-180μm

 

Production capacity〗:5-700t/h

It has the characteristics of high grinding efficiency, low power consumption, large feed particle size, easy to adjust product fineness, simple equipment process, small floor area, low noise, small dust, simple operation and maintenance, low operation cost, less consumption of wear-resistant materials, etc.

 

Comprehensive comparison, which is better, ring roller mill or vertical mill? The vertical mill has a large capacity, which is more suitable for large-scale and expanded production. The ring roller mill is suitable for the production of ultra-fine powder in small and medium-sized enterprises because of its energy-saving advantages, and the price is more affordable.
