The heat of mining in recent years has made the crusher industry rise rapidly, and crusher companies have been established one after another. But all kinds of crushers are dazzling, how to choose the one that suits you? Here, mining crushing equipment factory china introduces you to the common classification of crushers and their respective uses.
The following is a brief introduction to the eight most commonly used crushers
The first type: Jaw crusher is the first choice for first-level crushing. It has the characteristics of large crushing ratio, uniform product size, simple structure, reliable operation, easy maintenance, and economic operating costs. Crushers generally handle larger pieces of material, and the product size is coarser, usually larger than 8 mm. The product particle size is fine, up to 0.074 mm, or even finer.
The second type: impact crusher, commonly known as sand making machine, is the use of the famous "stone stone" crusher principle and technology, suitable for medium and fine crushing of various ores and rocks of different hardness, such as iron ore, non-ferrous metal ore, emery , High-hardness materials such as bauxite, quartz sand, brown corundum, perlite, basalt, etc., are the domestic and international construction, mining, metallurgical industries and highways, railways, bridges, hydropower, mineral grinding field and mechanism sand The core equipment of the industry. The crusher (is an ideal production equipment for construction sand, road construction sand, cushion material, asphalt concrete and cement concrete aggregate, so it is widely used.
The third type: Impact Crusher, which can handle materials with a side length of less than 100-500 mm, has a compressive strength of up to 350 MPa, has a large crushing ratio, and the materials after crushing are cubic particles, etc. advantage. Widely used in construction materials, ore crushing, railways, highways, energy, transportation, energy, cement, mining, chemical industry and other industries for medium and fine crushed materials. The discharge size can be adjusted, and the crushing specifications are diverse.
In the industry and silicic acid industry, it is suitable for crushing various ores and rocks with medium and above hardness. This machine has the characteristics of large crushing force, high efficiency, high processing capacity, low operating cost, easy adjustment, and economical use.
Fifth type: Compound crusher is a new type of high-efficiency fine crushing equipment that combines hammer breaking and impact breaking. It has a large crushing ratio, high crushing moisture content, and is ideal for processing materials with high moisture content. The granularity of the material can be adjusted arbitrarily, without the setting of sieve strips, materials with a large amount of sediment will not be blocked, and unbreakable materials can be automatically discharged into the machine body without causing damage to the equipment. The equipment has first-class crushing materials, high production efficiency, unique structure, stable operation, low noise, and easy maintenance.

Sixth type: hammer crusher, the crushed materials are coal, salt, chalk, gypsum, bricks and tiles, limestone, etc. It is also used for crushing fiber structure, scrap wood with strong elasticity and toughness, paper or crushed asbestos cement waste to recover asbestos fibers, etc. In addition, the hammer crusher can be used not only for crushing production lines and sand production lines, but also for replacing cone crushers in mineral processing production lines.
The eighth kind: pair roll crusher, pair roll crusher is also called double roll crusher, pair roll crusher, pair roll crusher, pair roll crusher (double roll crusher) it is suitable for feeding granularity less than 80mm, The granularity of the finished product requires a fine crushing operation of 50 mesh to 20 mm. Such as the use of cobblestones and construction waste to make sand artificially; mining finely crushed iron ore, quartz stone; ceramic industry crushed raw materials. It is suitable for coarse and intermediate crushing of brittle bulk materials in industries such as cement, chemical industry, electric power, mining, metallurgy, building materials, refractory materials, coal mines, etc. It has a large input particle size and an adjustable output particle size, which can resist compressive strength ≤160MPa The material is broken. Especially in the coal industry, using this machine to crush raw coal can be directly crushed as long as it is iron-removing, impurity-removing, and without gangue removal. The crushed material has uniform particle size and low excessive crushing rate, which simplifies the coal preparation process and reduces Investment and production costs.
