Ball mills and pulverizers are both mining grinding machines. Customers who are unfamiliar with the two products often don’t know how to choose when purchasing them. This article analyzes the two types of equipment and takes a look at the advantages of ball mills and pulverizers. What's the difference?

1. Differences in application fields

From the perspective of equipment categories, ball mills are mineral processing machinery, and grinding mills are industrial powdering equipment. Therefore, ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal mineral processing, and glass ceramics. and other production industries, for dry or wet grinding of various ores and other grindable materials. It is suitable for cement, cement bricks, refractory furnace materials, gypsum, limestone, calcite, gold ore, magnetite, and magnetic separation of iron ore. , slag, etc.

The grinding mill is mainly used for the high-fine grinding and processing of more than 280 kinds of materials in the mineral, chemical, construction and other industries with a Mohs hardness of no more than 9.3 and a humidity of less than 6%, such as gypsum and talc. , calcite, limestone, marble, potash feldspar, barite, dolomite, granite, kaolin, bentonite, medical stone, bauxite, etc.

2. Differences in equipment models

The ball mills produced by our company are divided into two types according to the ore discharge method: lattice ball mill and overflow ball mill. According to the shape of the cylinder, they can be divided into four types: short-cylinder ball mill, long-cylinder ball mill, tube mill and conical mill. Customers are choosing When selecting mineral processing ball mill equipment, the appropriate ball mill can be selected according to actual needs.

Our company produces a wide variety of grinding mills. Its representative equipment is Raymond mill, as well as ultra-fine grinding mills that require higher product fineness, high-pressure grinding mills with good pressure-bearing performance, and durable grinding mills. High-strength grinding mill with good grinding performance, as well as independently developed HGM German version grinding mill with advanced level.

3. Differences in working principles

The ball mill is a horizontal cylindrical rotating device. The material enters the bin evenly from the feeding device through the feeding hollow shaft. There are ladder linings or corrugated linings in the bin, which are filled with steel balls of different specifications. The rotation of the barrel generates centrifugal force to push the steel balls. It is brought to a certain height and then dropped, causing heavy impact and grinding to the material. After the materials reach coarse grinding in the warehouse, they enter the warehouse through the single-layer partition board. The warehouse is equipped with a flat lining plate and contains steel balls to further grind the materials.

The work of the grinding mill is to crush the large pieces of raw materials to the required feed particle size, then transport the materials to the storage bin by the bucket elevator, and then evenly send them to the grinding chamber of the host machine by the electromagnetic vibrating feeder. The material entering the grinding chamber is scooped up by the blade and enters between the grinding roller and the grinding ring to be ground. The blower blows the air from the diverter plate into the grinding chamber and sends the crushed powder to the analysis chamber. The speed-adjustable motor passes through the transmission device. The rotating analysis impeller is driven to sort, and the large particle materials fall back into the grinding chamber and are reground. The qualified fine powder enters the finished product cyclone powder collector with the air flow. After being separated from the air, it is discharged from the discharge port as the finished product. During the operation of the main machine, the blade system plays a very important role. It is located at the lower end of the grinding roller. When the blade and the grinding roller rotate together, the material is scooped up and thrown into the gap between the grinding roller rings to form a cushion layer. This layer of material is affected by the outward squeezing force generated by the rotation of the grinding roller to push the material. Crush it to achieve the purpose of making flour.

Of course, these differences cannot subdivide the two types of equipment. If you have the need to purchase such equipment, you can directly click on the online consultation. We will have a professional sales manager to recommend equipment suitable for you based on your actual production needs.
