What is the difference between grinding mill and crusher? When do I use the grinder? When will the crusher be used?
Many people wonder if the two kinds of equipment, the
grinding mill and the
crusher, are used together? What's the difference?
In fact, these are two different types of equipment, but both belong to one kind of mining machinery, which are used to crush and grind stone.
However, their appearance, working principle and incoming and outgoing materials are very different, and the principle and fineness of material crushing are also different.
Next, let's have a detailed understanding of the difference between the grinder and the crusher. When is the mill used and when is the crusher used?
Is the mill and crusher used together?
These two types of equipment can be used together.
When we want to build a grinding production line, we may need to use these two types of equipment at the same time.
But when we build the crushing production line, we only need to use the crusher. The pulverizer is used to
grind small particles of ore into powder with fineness similar to that of flour, generally including
Raymond mill,
micro powder mill and
ultra-fine mill; The crusher also has a variety of models, which need to be used together to break large ores into small particles. Common crusher models include
jaw crusher,
cone crusher and
impact crusher;
The working principles of the two types of equipment are different.
The structures and working principles of the two types of equipment are very different. The grinder is mainly used for grinding materials with grinding roller and grinding ring. Crusher mainly uses impact force, hammering force and squeezing force to crush ores. In terms of production capacity, the output range of the pulverizer is smaller than that of the crusher. The output of the pulverizer is only a few hundred tons, but the output of the crusher is generally hundreds or even thousands of tons. The feeding requirement of the mill is 15-30mm, and the finished product fineness is very fine. The range of finished products of the crusher is relatively wide, with a wide range of finished products, including coarse, medium and fine crushing. I believe you have a basic understanding of these two devices.
When our material processing fineness is relatively fine and reaches the powder state, we need to use a pulverizer. However, when we build a pulverizing production line, if the material is too large, we may also need to use a crusher to process the material first. When our requirements for finished products are stones or sand, we need to use a crusher and a sand machine. The sand machine is also called an impact crusher, which belongs to a type of crusher. To build a crushing production line, a variety of crushing equipment, including coarse crushing, medium crushing and fine crushing, are required to be used together to produce qualified products
How to select a suitable grinding mill?
The grinder is widely used in various fields, such as processing of non-metallic minerals, chemical raw materials, advanced ceramic raw materials, fine abrasives, etc. In recent years, equipment such as ultra-fine grinding and fine classification process has been developed rapidly. There are more than 100 manufacturers of various ultra-fine grinding and fine classification equipment, with different scales and equipment quality. In addition, because the country has not yet formulated a unified performance bid, testing specifications and quality standards for ultra-fine grinding and fine classification equipment, various manufacturers have different descriptions of their equipment performance indicators. In the face of numerous mill equipment, how should customers choose a mill?
1. Whether the product fineness requirements are met;
2. Whether the output or scale requirements are met. The production capacity of a single equipment is mainly considered, and the principle is to minimize the number of equipment on the premise of meeting the production requirements;
3. Whether the unit energy consumption is low. The specific energy consumption (kw. h/T) is lower. The lower the unit energy consumption, the lower the product production cost, and the stronger the market competitiveness of the product;
4. Whether the wear of equipment is small. On the one hand, the wear of equipment will reduce the service life of the main parts and components of the equipment and the whole machine, and increase the cost; on the other hand, it will affect the quality or purity of the product. When selecting equipment, the working strength, material and wear resistance of the worn parts should be compared.
5. Whether the quality monitoring means are perfect. Perfect quality control means can ensure the stability of product quality and improve the efficiency of crushing and grading operations;
6. Whether the supporting performance of the equipment is good, and whether the process system is simple. The equipment with good supporting performance and simple process shall be selected as far as possible;
7. Whether the environmental protection indicators are up to standard. The equipment with dust emission and noise meeting the requirements of national environmental protection, labor, safety and health standards shall be selected;
8. Whether the classification efficiency of classification equipment is high. Equipment with high classification efficiency shall be selected as far as possible;
9. Products from manufacturers with guaranteed mechanical manufacturing and sound service system shall be selected to ensure reliable quality.
