Abstract

The invention discloses a circularly breaking and sieving system, which comprises a breaking device and a secondary sieving machine. A fourth conveying belt for conveying materials broken by the breaking device to the secondary sieving machine is arranged under the breaking device, and a fifth conveying belt for conveying materials which are not sieved out by the secondary sieving machine to the breaking device is arranged between the secondary sieving machine and the breaking device. The technical scheme of the circularly breaking and sieving system and the method thereof controls grain size of sieved materials through pore size of a sieving machine without controlling the grain size through the breaking device. Grain size control is simple and reliable. Through control of first sieving and second sieving of the materials, the phenomenon of over-breaking is avoided, carbon content of fly ash is greatly reduced, energy consumption is reduced, and economic benefit of boilers is greatly improved. An original coal manufacturing system is changed into horizontal technological distribution from vertical technological distribution, a technological route is shortened and simplified, floor area is reduced, and cost for investment of capital construction is greatly saved.

Description

technical field [0001] The invention relates to a circulating crushing and screening system and method thereof which integrates coal taking, conveying, screening, crushing, re-screening and re-crushing. Background technique [0002] The existing coal-making system equipment process layout is that the bulldozer, loader or crane grabs the fuel into the coal belt, enters the crushing building through the trestle, and the fuel is screened and crushed (or directly crushed without screening) through the The coal belt enters the coal storage bunker. The commonly used process arrangements for screening and crushing are four process arrangements: one screen and one break, one screen and two breaks, two screens and two breaks, and only crushing without screening. The problems existing in the equipment process layout of the existing coal production system are; [0003] According to the technological layout of the coal feeding belt, screening and crushing equipment, the minimum height...
