Description

Technical Field

[0001] The utility model relates to the field of cement production, in particular to a novel mill interior partition device. Background Art

[0002] In the second half of the year, the mixed materials (water slag, black slag, etc.) of our company increased by about 10% compared with the original, and the moisture content was relatively high, and the partition board was easily blocked, which affected the ventilation and output of the mill. The output of the mill dropped significantly, and the grinding head often blew dust and was fully ground. At that time, the output of the mill was about 100t / h (mineral powder) at 42.5 cement units, and about 75t / h at 52.5 cement units (mineral powder, the grinding fineness was 0.045, and the sieve residue was about 48%. During the production process, the moisture content of the materials changed more, and the poor ventilation in the mill was more serious. The ventilation capacity could not effectively improve the grinding conditions in the mill. First, during the grinding process, the water vapor in the mill could not be discharged in time, resulting in an increase in the temperature in the mill, static electricity was adsorbed on the surface of the grinding balls and linings, and a buffer layer was formed, which reduced the grinding efficiency and aggravated the ball sticking phenomenon; second, the wind speed between the first warehouse and the second and third warehouses did not match, resulting in excessive grinding in the first warehouse, and the second and third warehouses did not play their actual efficiency, which ultimately increased power consumption and increased costs.

[0003] In the existing technology, although a certain cement partition effect can be achieved during use, there are defects: the existing cement mill internal partitions lack the effect of efficient ventilation and the function of convenient disassembly, which leads to reduced cement production output and affects the construction period. In view of this, we propose a new type of mill internal partition device to solve the above problems. Utility Model Content

[0006] When used, this device can make up for the shortcomings of previous partitions and achieve large-scale ventilation without affecting the processing of cement. In addition, this device has a convenient disassembly function, which is convenient for regular cleaning and maintenance, and is equipped with a retaining frame to achieve a reinforcement effect. It can occupy a unique position in the existing group of cement partitions.
