How to measure the filling amount of the grinding media of the sander One

Sander media and its loading:

The sand mill can use glass balls, zirconia balls and steel balls as grinding media. Each medium should be cleaned and filtered before being loaded into the cylinder with a uniform particle size.

The use of a certain medium for grinding is selected according to the fineness and viscosity of the dispersed material. The principle is: the harder the material should be, the harder medium should be selected; the finer the product requirements, the finer the particle size of the medium and the corresponding increase in the loading amount; the coarser particle size of the material to be ground should be coarser.

The loading amount of the grinding media of the horizontal sander is about 85% of the volume of the cylinder. The specific amount of the grinding media should be determined according to the particle size of the medium, the sensitivity of the material to the temperature, and the material variety.

two. Note on the media loading of the sander:

If the temperature is too high during production, the loading should be reduced to control the grinding temperature in the desired temperature range. If the product outlet temperature is too low, consider increasing the medium to increase efficiency before increasing the speed.

three. The service life of the grinding media: to achieve the best efficiency, the medium in use should be replaced and added in time, and the broken parts of the broken and removed parts should be removed to supplement the corresponding new medium. The service life should be based on different material types to find out the law, and replace it at the right time. Fourth, the factors affecting the service life are as follows:

1. Material viscosity: It is recommended to increase the viscosity of the material as much as possible to reduce wear.

2. Speed: The higher the speed of the dispersion shaft, the faster the wear. Empty load: When cleaning the medium of the cylinder, try to shorten the time. Do not open the empty car before there is any material entering the cylinder.

4. Dispersion of the material itself: The high hardness of the material itself not only affects the life of the grinding medium, but also affects the life of the cylinder and the dispersion disc.https://www.wuxiorient.com/
