Improving the output of ball mills is the common wish of every user and manufacturer. After years of research and simulation experiments, Yingkuang Machinery has found the best parameters and optimized the existing models and specifications. In addition to changing the material type, particle size and moisture content, the optimization options are mainly the optimization of the internal structure and grinding body. At the same time, according to the flow rate of the material, how to optimize the ball mill structure to improve the output of the ball mill? Let's ask the technical staff of Yingkuang Machinery to give us a detailed introduction.

1. Strengthen the ventilation in the energy-saving ball mill

The ventilation in the energy-saving ball mill has a significant impact on the production quality. Good ventilation can not only discharge the fine powder from the mill in time to avoid over-grinding, but also take away the heat of grinding, reduce the temperature in the mill, reduce gypsum dehydration and tail warehouse paste ball blocking. It can be improved by opening a vent at the feed inlet, improving the feed inlet spiral, making the material chute into a stepped shape, enlarging the center hole of the partition plate and the discharge grate plate, and strengthening the air lock at the discharge port. It not only solves the blocking phenomenon, but also increases the ventilation area.

2. Partition plate and discharging grate plate

The screening partition plate is a new type of partition plate that can classify the materials passing through the partition plate. Its main function is to screen the materials entering the fine grinding chamber and prevent the coarse particles from entering the fine grinding chamber, creating conditions for the fine grinding chamber to use micro-grinding bodies with large specific surface area and high grinding efficiency. That is, the new partition plate not only increases the function of controlling the material flow and balancing the crushing capacity of each chamber, but also can achieve the classification of coarse and fine particles and the role of forced lifting of materials, so that the finer materials can enter the fine grinding chamber for grinding as soon as possible.

3. Activation device

In order to give full play to the grinding potential of the energy-saving ball mill, an activation device can be added to the mill to create three-dimensional movement conditions for the micro-medium, strengthen the grinding capacity, and make more full use of the kinetic energy of the grinding body, thereby greatly improving the grinding efficiency. Depending on the different requirements of the product, 2~5 paths are installed along the axial direction of the energy-saving ball mill, and one is installed every other display along the longitudinal direction and the liner of the energy-saving ball mill. Due to the activation device, the grinding body not only moves in a circular motion along the liner of the energy-saving ball mill, but also moves in an axial direction. At the same time, the retention area where the grinding body far away from the cylinder liner cannot be effectively driven by the liner of the energy-saving ball mill and the movement degree is weakened can be eliminated due to the activation device.

4. Liner
In addition to its protective function, the liner is mainly used to adjust the dynamic distribution and movement trajectory of the grinding body. Its form must match the speed of the energy-saving ball mill and the material characteristics. The use of various new liners has greatly improved the adjustment of the movement state of the grinding body and the adaptability to the material. The tail bin of the energy-saving ball mill uses a hyperbolic liner, which has inclined surfaces in both the axial and circumferential directions, which can not only increase the lateral distribution of the steel balls, but also improve the grinding efficiency of steel forgings and steel balls.
