Abstract

The invention discloses a sieving and crushing integrated machine. The sieving and crushing integrated machine comprises a machine housing, a sieving and distributing machine (1) arranged at an upper part of the machine housing, and a sieving and crushing machine (35) arranged at a lower part of the machine housing, wherein the sieving and distributing machine (1) comprises a charge hole (2), an arc-shaped distributing plate (6), an iron remover (11), a transmission device, a flange type sieve shaft (4) and a filter sieve shaft (5); the sieving and crushing machine (35) comprises a main rotor, an arc-shaped counterattack sieve roller set, a particle size adjusting device and a transmission device; and a charge hole (36) of the sieving and crushing machine is positioned below a discharge hole (9) of the sieving and distributing machine. The sieving and crushing integrated machine has the following creative effects: the original two-stage crushing and one-stage sieving mode is changed to be a one-stage sieving and one-stage crushing mode, so that a system structure is simplified; problems of material adhesion and blockage, high iron content, low sieving and crushing efficiency, high power consumption, non-uniform ring hammer wear, unadjustable particle size, high difficulty in overhauling and replacement of spare parts, inconvenience in operation and the like are solved; and the sieving and crushing integrated machine is a major innovation of sieving and crushing equipment technology.

Description

technical field

[0001] The invention relates to the technical field of screening and crushing devices for materials with different particle sizes, in particular to a screening and crushing integrated machine. Background technique

[0002] It is well known that thermal power plants mainly use pulverized coal boilers and circulating fluidized bed boilers, and their fuels are all pulverized coal and coal gangue particles with a certain particle size. The particle size of the raw coal coming from the coal mine is uneven. Most of the particle size of the raw coal does not need repeated crushing. The screening and crushing machine can directly separate the qualified particle size, and the remaining large particle size material enters the Crusher crushed to qualified particle size. In the pulverized coal furnace screening system, the raw coal that accounts for more than 60% is usually screened out; the feed particle size is 0-500mm; the screening particle size is 30-50mm; the crus...
