Product Introduction

    Cement ball mill is the key equipment for crushing and crushing materials. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics. Dry and wet grinding with other abrasive materials. In addition to the existing cement ball mill equipment, Henan Zhengzhou Machinery Factory can also design and produce complete cement production lines according to user requirements, and our company will also send technical personnel to help users install and debug the mill on site until the trial production is successful.

    Classification and characteristics of cement ball mill

    (1) Ordinary cement ball mill: Most ordinary cement ball mills are used in circulating grinding systems, which are characterized by high grinding efficiency, large mill output, and low power consumption, especially when grinding slag cement. . The general mill output can be increased by 15-20%, and the power consumption can be reduced by about 10%. In addition, the temperature of the finished product can be reduced by 20-40 ° C, and the product fineness can be easily adjusted.

    (2) High-fine and high-yield cement ball mill: High-fine and high-yield cement ball mill is mainly used in open-flow grinding systems. Its features are simple system equipment and technological process, low investment, and small plant floor area. The mill adopts advanced special powder separation compartment device for internal powder selection, the fine grinding compartment has added activation device, and the tailing has special discharge. Plate, reduce the size of the grinding medium in the grinding chamber as much as possible, greatly improve the grinding efficiency, and achieve the purpose of high output and low energy consumption.

    Working principle of cement ball mill

    First, the material enters the first silo of the mill spirally through the hollow shaft of the feeding device through the feeding device. There is a stepped lining or a corrugated lining inside the chamber, which contains steel balls of different specifications. The centrifugal force generated by the rotation of the cylinder brings the steel balls to a certain level. Falling after the height, it has a heavy impact and grinding effect on the material. After the cement ball mill reaches the first bin for rough grinding, it enters the second bin through a single-layer partition board. This bin is inlaid with a flat liner and steel balls to further grind the material. The powder is discharged through the discharge grate plate to complete the grinding operation.

    Structural characteristics of cement ball mill

    The cement ball mill is composed of the feeding part, the discharging part, the turning part, and the transmission part (reducer, small transmission gear, motor, electronic control) and other main parts. The hollow shaft is made of cast steel, and the inner lining can be replaced. The rotary gear is processed by casting hobbing. The cylinder is equipped with a wear-resistant liner, which has good wear resistance. The machine runs smoothly, works reliably, saves energy and protects the environment.

    Note: Dry ball mill and wet lattice ball mill can be selected according to materials and ore discharge methods.

    Performance advantages of cement ball mill

     Good spindle performance and high throughput

    The main bearing uses a large-diameter double-row self-aligning stick bearing instead of the original sliding bearing, which reduces friction and energy consumption, and the mill is easy to start.

    The structure of the end cover of the ordinary mill is retained, and the large-diameter inlet and outlet ports have a large processing capacity.

     Simple structure and smooth operation

    The feeder is divided into a combined feeder and a drum feeder, which has a simple structure and is installed separately.

    There is no inertial impact, the equipment runs smoothly, and the mill shutdown and maintenance time is reduced, and the efficiency is improved.
