How many types of vertical mills are there? Which one is better to choose?

Compared with horizontal grinding mills, vertical grinding mills save more space and are very popular among people in the industry. However, there are many kinds of vertical grinding mills on the market, which makes many friends choose and buy vertical grinding mills. I was dazzled by the powder machine. So today I will introduce to you some of the more commonly used vertical mills on the market, and compare which one has better quality, so that you can choose in the future.

Introduction to commonly used vertical grinding mills

1. Ultra-fine vertical grinder
Ultra-fine vertical mill is suitable for ultra-fine grinding of more than 100 kinds of materials such as non-flammable and explosive, non-metallic minerals, such as limestone. The hardness of the processed materials should be below level 7, the humidity should not exceed 6%, and the output should be one time The particle size of the finished product is between 0.038mm-0.02mm, and the finest can reach 0.005mm.

2. Vertical roller mill
Vertical roller mills mainly focus on the three major fields of coal powder, slag and non-metallic ores. One machine has multiple functions. It can not only grind powder, but also classify, crush, dry, etc. It is suitable for grinding raw materials and clinker, and can also be used as a pre-grinding and subsequent mill to greatly increase output.
When the moisture content of the finished product is required to be smaller than the moisture content of the raw material, hot air can be directly passed through, and the drying capacity is strong, which can save a dryer.

3. Raymond mill
Raymond mill is suitable for processing more than 280 kinds of non-flammable, non-explosive and non-food materials. The hardness of the processed materials should not exceed 9.3, and the humidity should be below 6%. It can be slightly higher, but it cannot exceed 10 %. If the moisture content is too high, dry it naturally if the output is small. If the output is large, a dryer will be required. The particle size of the finished product is between 0.125-0.044mm, which can be adjusted arbitrarily according to requirements; the production capacity is about 1-120t/h.

Raymond mill can be divided into 3R, 4R, 5R and other models according to the number of grinding rollers. R represents the number of grinding rollers. Generally, ordinary Raymond mills below 93 (Raymond 62, high-strength 66-92) have 3 rollers. , 93 and above (high strength 93, 97) are 3 or 4 rollers; 4119 is 5 rollers, 4525 is 4, 5, 6 rollers.

If you need a vertical mill with less noise pollution, you can choose a vertical roller mill;
If you need to grind the finished product coarsely, and the working site is small and the investment budget is small, you can choose a Raymond mill;
If you want to get it right in one step without setting up a dryer, you can choose a vertical roller mill or an ultra-fine vertical mill, both of which have their own drying systems.
If you need a small output, you can choose a Raymond mill; otherwise, you can choose the other two.
