Common stone crusher and fine crusher belong to stone crushing equipment strictly, whose function is to crush materials. However, many users have strict requirements and limits on discharge during material processing, so they do not know which equipment to choose? This paper introduces two kinds of equipment in detail combined with application practice.
1、 Analysis of similarities
1. Both equipment are stone crushing equipment, which can directly or indirectly crush materials, and can be used in various production lines, and in the actual application process, they have particle size adjustable, and the two equipment can be the same if conditions permit.
2. Can handle medium hardness materials, and in the production and operation are quite simple and convenient, usually, the crusher is generally default jaw crusher, jaw crusher can be divided into coarse and fine, and fine is the traditional sense of the fine crusher.
3. These two types of equipment have the advantages of environmental protection, which is mainly reflected in the fact that they will not produce any noise or cause any harm to the environment in the process of work. Therefore, these two types of equipment can keep pace with the times, conform to the trend of development of the times, and inject new vitality and vitality into the future development of the mining field.

2、 Analysis of differences
1、 In terms of discharge, the fine crusher is more refined than the crusher, and in terms of output, the crusher has higher capacity than the fine crusher, which is determined by the internal structure of the equipment. The user needs to make a reasonable choice in the process of equipment selection, so as to achieve a more satisfactory effect.
2. In the production line, the crusher (jaw crusher) is mainly used as the front-end crushing equipment, also known as the first-class crushing, while the fine crusher is usually used as the second-class crushing equipment, so they are quite different in function, performance, function and other aspects. As for which equipment to choose for crushing, the user needs to make reasonable purchase under the guidance of professionals.
