Dustless sieving and crushing integrated machine

Abstract

The invention relates to a dustless sieving and crushing integrated machine which comprises a machine frame and crushing cavities, wherein the crushing cavities consist of a primary crushing roller, an impact plate and a primary impact roller, a secondary crushing roller and sieving rollers, and a tertiary crushing roller and sieving rollers respectively; a rubber plate at the bottom of the dustless sieving and crushing integrated machine and a conveyor belt form a compact cavity body; a material inlet and an air draft opening are further formed in the top of the dustless sieving and crushing integrated machine respectively; an air draft dust removal device is arranged outside the air draft opening. The dustless sieving and crushing integrated machine is dustless sieving and crushing integrated mechanical equipment capable of realizing continuous crushing, continuous sieving and efficient crushing without dust.

Description

technical field [0001] The invention relates to a dust-free screening and crushing integrated machine. Background technique [0002] Existing crushing equipment includes ring hammer crusher, double-roll crusher, and hammer crusher. When these types of equipment are used to crush materials, there is no screening function, the material distribution is uneven, and the gear plate, ring or hammer head wear quickly. The discharge particle size is difficult to control, and the size is different. If it is used to crush coal, the coal particles will be sent to the fluidized bed boiler for combustion. The fluidized bed boiler does not burn well, which will reduce the combustion efficiency of the boiler, and it is easy to cause coking at the bottom of the furnace, which will affect the performance of the boiler. burning effect. In addition, the dust leaks out during the operation of the equipment, which pollutes the environment; the energy consumption is high; the maintenance labor in...
