Abstract

The invention discloses a circulating type cement clinker crushing device. The device comprises a lump material crushing sleeve and a lump material crushing screw coaxially arranged in the lump material crushing sleeve, spiral crushing blades are arranged on the lump material crushing screw, and each axial end of the lump material crushing sleeve is respectively provided with a to-be-crushed lumpmaterial inlet and a crushed lump material outlet; the device also comprises a vertical conveying screw, a separation and conveying inner sleeve and a crushed particle separation outer sleeve, whereinthe vertical conveying screw, the separation and conveying inner sleeve and the crushed particle separation outer sleeve are coaxially sleeved arranged from inside to outside, spiral conveying bladesare arranged on the vertical conveying screw, and a plurality of separation screen holes are arranged in the separation and conveying inner sleeve; the upper end of the separation and conveying innersleeve communicates with the to-be-crushed lump material inlet, and the crushed lump material outlet communicates with the lower end of the separation and conveying inner sleeve. According to the device, high-efficiency and uniform crushing of the large-size lump cement clinker can be realized, and the lump cement clinker which is not crushed thoroughly can be sent back to the crushing device again.

Description

technical field [0001] The invention relates to the technical field of a cement clinker grinding device, in particular to a circulating cement clinker crushing device. Background technique [0002] Cement clinker needs to be ground to a suitable particle size, so as to increase the hydration area of ​​cement products and accelerate the hydration speed of cement, so as to meet the speed requirements of cement paste coagulation and hardening during use. For large pieces of cement clinker, grinding rollers are usually used for crushing, but due to the large volume difference of cement clinker, the grinding rollers have the problems of large jump and uneven crushing effect; and screw crushing is more effective than grinding roller crushing. High efficiency and lower energy consumption, and can avoid the problem of uneven crushing effect of grinding rollers. [0003] In addition, the blocky cement clinker forms granular cement clinker after preliminary crushing. In order to sepa...
