Jaw crushers are mainly used for coarse and medium crushing, and their original design is to handle materials with larger particle sizes. When the particle size of the material is too small, the crushing ratio that the crusher needs to achieve will decrease, resulting in reduced crushing efficiency. This is because fine-grained materials stay in the crusher for a relatively long time and are not easily effectively crushed, which may increase the wear and energy consumption of the equipment.
Fine-grained materials tend to stick together to form larger clumps, which may get stuck in the crushing chamber during the crushing process, causing blockage and affecting the normal operation of the crusher. In addition, fine-grained materials may also adhere to the inner wall of the crusher, increasing the difficulty of cleaning.
Fine-grained materials will cause more serious wear on the jaw plate, liner, and other parts of the crusher during the crushing process because fine-grained materials have a higher specific surface area and more edges and corners, which will increase the contact and friction with the crushing parts.
If the fine-grained materials contain more hard impurities or foreign matter, these impurities may damage the key parts of the crusher, such as bearings, transmission devices, etc., during the crushing process, thereby affecting the overall performance and life of the equipment.
In order to avoid problems such as reduced crushing efficiency, increased equipment wear, increased operating difficulty, and maintenance costs, fine-grained materials should not enter the jaw crusher. In practical applications, appropriate crushing equipment should be selected according to the particle size and properties of the material to ensure the smooth progress of the production process and the long-term stable operation of the equipment.
