Description

Anti-blocking mechanism for grinding of cement mill

Technical Field

The utility model relates to a cement industry equipment technical field specifically is a cement grinds out and grinds and prevent blockking up mechanism.

Background

The grinding speed and quality of the cement mill can be directly influenced by the grate plate, the grate plate comprises a grate, a central sieve plate, a support plate and the like, the grate plate comprises a plurality of sector ring panels, a plurality of grate holes are formed in the panels, ground clinker in the bin can be discharged to the next intermediate bin in time, and materials are discharged by a lifting plate on the support plate, so that the accumulation of the materials is avoided, and the normal work is influenced; the holes between the grating plates can play a role in ventilation and heat dissipation, so that the temperature in the mill is reduced, and the working efficiency of the mill is improved.

At present, most grate plates of production lines are cast by wear-resistant alloy cast steel, the width of a grate seam is 6mm-10mm, grinding bodies and fragments with the size close to the grate seam are generated in the grinding process and are easily clamped in the grate seam, and the grate seam is blocked after long-term accumulation because the thickness of the grate seam reaches about 60 mm. The blockage of the grate slots causes the material passing in the mill and the ventilation area to be reduced, and even the material is forced to be discharged from the central hole, and the ventilation resistance is increased.

Because the diameter of the central hole is limited, when the yield of the mill is high, the discharge amount at the central hole can not meet the yield requirement of the mill, the excessive material storage amount in the mill causes the phenomena of reduction of the grinding efficiency in the mill, poor ventilation, easy full grinding of the mill, dust emission or material return of a grinding head and the like, and the yield operation is forced to be reduced. Meanwhile, after the grate plate is blocked, the ventilation in the mill basically and completely passes through the central hole, and the wind speed at the central hole is higher, so that a central wind tunnel effect is formed, the result that the fineness of the mill is easy to be coarse is caused, and the capacity of the mill is seriously restricted from being exerted.
