The hardness of the stone is different, so when we choose the crushing equipment, we also need to consider a factor. The new cone crusher will be suitable for crushing different ores and rocks with medium hardness and above.
Cone crushers are divided into standard type and short head type, which are generally used for medium and fine crushing. Standard type, generally used for secondary crushing, that is, medium crushing. The short-head type is generally used for fine crushing, that is, to terminate. There are four types of cavities for cone crushers. They are too thick, thick, medium and fine.
How to choose a new cone crusher, Qingzhou Jianyuan Machinery Co., Ltd. gives you sincere suggestions as follows.
The principle of selection is to look at the size of the incoming and outgoing particles. If the feed amount is larger, the product size is coarser.
The standard cone crusher is mainly used for open circuit, while the short-end crusher is mainly used for closed circuit. When choosing a lining board, users generally have to consider three factors: the output, power consumption and wear resistance of the lining board; generally, it should be carried out according to the following principles: large feed size; particle size change; feed size distribution; material hardness; material Abrasion resistance. The longer the liner, the higher the power consumption. Use short liner for hard materials and long liner for soft materials. In terms of material distribution, use short liners for fine materials and long liners for coarse materials. Generally speaking, at the closed side discharge port, the feed size distribution is less than 10% of the material. When it is greater than 10%, the power consumption increases and the product particle size becomes thinner. The increase in the moisture content of viscous materials will affect the throughput of materials. Generally speaking, the water content of the material is less than 5%. In terms of power usage: the standard cone crusher should achieve 75% to 80%, and the short head cone crusher should achieve 80% to 85%.
Due to its harsh environment, large dust, and poor maintenance by some users, various problems often occur during operation. The following issues should be paid attention to during the operation of the new cone crusher to realize the normal operation of the machine. When the cone crusher is working, the feed is even and there is no segregation. If the feed is uneven, the production capacity will drop, the product size will be too large, the spring action will be frequent, the bowl bearing pressure will be high, and the power consumption will increase. There should be an iron removing device to prevent the crushing chamber from over-ironing. If the spring is too frequent, it may cause a broken shaft accident.
