The influence of feed speed on the work of impact crusher
The impact crusher has high crushing efficiency and good product shape. It is used as an indispensable equipment in the construction of highways and high-grade highways. Therefore, its production capacity and efficiency have a great impact on the production of the production line. The rotor feeding speed is a very important parameter, which has a great influence on the production capacity and crushing efficiency of the crusher.
The influence of the rotor feeding speed on the production capacity of the crusher:
The increase of the rotor speed must correspondingly increase the speed of the material entering the rotor, otherwise there will be negative effects such as over-crushing and excessive return of the material. In the process design, different rotor feeding speeds can achieve different production capacities. The required production output can be obtained by adjusting the rotor feeding speed, and this adjustment capacity can reach nearly 60%.
The influence of the rotor feeding speed on the efficiency of the crusher:
The feed speed of the impact crusher material when it enters the rotor should have a reasonable range, that is, it should meet the maximum and minimum speeds. In the actual application process, if the material has good crushability, a high speed should be used, and if the material has a poor crushability, a small speed should be used. In any case, its value cannot exceed the calculation range.
The influence of the rotor feeding speed on the wear of the blow bar:
The feeding speed of the rotor will affect the number of times the blower impacts the material. In the design and selection of the equipment, the feed speed of the equipment will affect the number of times the blower impacts the material. In the actual work process, the flow rate of the material in the process is required to be stable. If the feeding speed is small, the number of blows will be more. The sharp corners of the working face of the hammer are quickly ground into rounded corners. This state makes a large amount of material punch up, and the result is that the material is always repeatedly crushed in the first crushing cavity, which not only increases The number of blows of the blow hammer aggravates the wear of the blow hammer, and aggravates the over-crushing phenomenon of the crushed materials in the counter-attack, resulting in excessive powder. In severe time, the feed cavity is blocked and the production capacity is drastically reduced.
