The crusher industry belongs to a traditional machinery industry. Today, there are dozens of types of crushers. In the stone production line, crusher equipment is indispensable, so how to choose a suitable crusher for your own production line is very important. Scientific and reasonable crusher equipment can bring economic benefits to our production. Today we will teach you how to choose the suitable crusher equipment.
1. The purpose of the crusher
The first thing to consider when choosing a crusher is what the final product is to be produced by the whole set of crusher equipment. In stone production, there are generally nothing more than crushed stone production lines and sand production lines. The main difference lies in the size and use requirements of the final product.
2. The nature of the raw materials of the production line
The hardness, gradation, mud content and water content of the raw materials of the production line are very important parameters. Different raw materials should choose different crushing equipment. If the hardness of the raw material is relatively large, we generally choose a jaw crusher for the primary crushing and a hammer crusher for the secondary crushing. For materials with average hardness, a hammer crusher can be used directly. The gradation of raw materials will also affect the overall parameters. For rocks produced directly from the quarry by blasting, the crusher should be selected according to the particle size of the rock; for the sand and pebble layer, the primary crusher should be selected according to the gradation curve; When the mud content and water content are high, the crushing equipment that can handle wet materials should be considered. In general, the process flow of the equipment and the productivity of each part should be selected according to the particle size of the raw materials, and the form of the coarse crushing equipment should be selected according to the hardness of the raw materials.
3. Product quality requirements
A stone production line has different quality requirements for its products according to its products. The quality of the product includes granularity, gradation, grain shape, etc. The processing quality of the product is related to the crushing machinery and production process. When the product size is small, the crushing ratio of the crusher is relatively large. The more the product size, the more complicated the equipment. In order to obtain various grades of crushed stone, an independent sieving machine must be specially set up for classification. In many projects, the dust content in the product should not be too high, which is harmful to the quality of concrete. When the dust content exceeds the standard, a cleaning process must be added to the production line.
4. Output of the production line
The production output of the production line is an important parameter for selecting crushing and screening equipment. The target output is an important factor in deciding which type of crusher to choose. The specific model of the crusher can be based on the output, so that the entire crushing production line can reach the output without causing waste.
