Abstract

The invention discloses a novel vertical mill with a lower air inlet function and a built-in combined high-efficiency powder selection function. The novel vertical mill comprises a powder selecting unit and a grinding unit; the powder selecting unit comprises a first-stage powder selecting part and a second-stage powder selecting part, the first-stage powder selecting part includes a central chamber located under the second-stage powder selecting part and edge chambers equidistantly distributed in the circumferential direction of the central chamber at equal intervals, the outer end of each edge chamber is provided with a feeding opening and an air inlet, the upper end of the second-stage powder selecting part is provided with a fine powder discharge port, and the lower end of the second-stage powder selecting part is provided with a coarse powder discharge port; and the grinding unit is fixed to the lower end of the central chamber, and the coarse powder discharge port is downwards inserted into the grinding unit. The novel vertical mill is more compact and reasonable in structure, smaller in occupied space, high in powder selection efficiency and lower in cost, and the novel vertical mill and a mill can be assembled together.

Description

technical field [0001] The invention relates to the field of classification and grinding of powdery materials, in particular to a combined dynamic powder selection and grinding machine. Background technique [0002] At present, in the cement raw material and grinding system, the high-efficiency and energy-saving process system composed of roller press or vertical mill, ball mill, V-type separator and fine separator has the characteristics of low energy consumption and convenient operation. The industry is becoming more and more popular. However, in the current process system, there are generally problems such as large installation site and low powder selection efficiency, which cause the grinding system to fail to meet production standards, and the cost is high. Especially for the retrofit project of energy-saving technology for old lines, the available space and funds are limited, and the owners have strict requirements, etc., which often cannot be met by traditional proce...
