The difference between hammer crusher and toothed roll crusher

The main mode of action of toothed roller crusher is splitting, accompanied by impact and bending. This crushing equipment can usually be divided into single tooth roller crusher and double tooth roller crusher two kinds. The power consumption of toothed roller crusher is low, and the pulverization degree of crushing products is low, energy saving and environmental protection. Gas shortage is unable to break hard materials, tooth roller is easy to wear, production efficiency is low. It is suitable for crushing bulk raw coal in coal preparation plant.

The main operation mode of the hammer crusher is the impact group of the high speed rotary hammer. It is suitable for the crushing of dry brittle materials, for example, the coal can be broken to 13-3mm below, and can ensure that the particle size of the product is uniform, not mixed with too large particle size of the product particles, in coal preparation plant is mostly used in coal crushing and fine crushing operation. According to the number of rotors, hammer crusher is divided into single rotor type and double rotor type two types, single rotor hammer crusher is divided into reversible type and irreversible type two. Compared with other types of crusher, hammer crusher has the advantages of simple and compact structure, large production capacity, large crushing ratio and less power consumption. The main deficiency is that the grate is easily blocked when the material moisture is high; Hammer head and grate wear faster; In addition, if the rotor is not balanced, it will produce harmful vibration when rotating at high speed. If the hammer head does not meet the requirements of strike balance, it will also produce harmful forces, additional energy consumption and reduced bearing life.
