Advantages and Disadvantages of Vertical Shaft Impact Crusher

The vertical shaft impact crusher is a fine crushing equipment, suitable for crushing and shaping soft, medium-hard and extremely hard materials. It has higher output and efficiency than other types of crushers. Compared with the previous hammer crusher and roller crusher Such equipment has the characteristics of high sand production rate and good grain shape of finished products.

Working principle: When the vertical shaft impact crusher works, the materials are sent from the top center feeding barrel to the rotor center, transported to each discharge chamber by the material distribution pile, and directly enter the high-speed rotating impeller. Under the action of centrifugal force, they are crushed with other materials. A part of the material shunted around the impeller in the form of an umbrella is impacted. The material is broken due to repeated eddy current impact and friction between the impeller and the casing, forming a closed-circuit crushing cycle. Finally, the material reaches the required level through screening control. Required finished material particle size.

Advantages: The optimized crushing cavity can increase the material throughput by 30%, and the equipment has both the functions of sand making and shaping; the modular design of thin oil type and grease type allows users to choose the lubrication method according to the actual situation to achieve Overall interchangeability, easy to operate; optional center or peripheral feeding methods, flexible adjustment, can avoid long adjustment time in practical applications, improve work efficiency; perimeter protection can be flipped up and down, extending the service life of the combined throw The head only needs to replace worn parts, which can reduce the use cost by 30%; the air flow in the vortex chamber is self-circulating, coupled with a pulse dust collector and a noise eliminator, to achieve green and environmentally friendly sand making.

Disadvantages: When the moisture content in the material is large, it is easy to adhere to the crushing cavity, which can easily cause blockage during the discharging and conveying process, resulting in a decrease in sand making capacity; due to the impact crushing principle, its striking parts, such as Blow hammers, throwing heads, peripheral protection plates, lining plates, etc. wear out quickly during use, which will increase the frequency and cost of replacement of accessories.
