Sand mill overview Sand mill, also known as bead mill, is mainly used for wet grinding of chemical liquid products. According to the performance, it can be roughly divided into vertical sand mill, horizontal sand mill, basket sand mill, Rod type sand mill and so on. Mainly by the body, grinding cylinder, disperser, bottom valve, motor and feed pump, the feed speed is controlled by the valve. The grinding media of the device are generally divided into glass beads, zirconia glass beads, zirconia beads, and the like. Feed pumps generally use gear pumps, diaphragm pumps, and other thick slurry feed pumps.
Sand mill sand mill is a kind of high-efficiency grinding and dispersing equipment widely used in industrial fields such as paint, coating, cosmetics, food, daily chemical, dye, ink, medicine, magnetic recording material, ferrite, photographic film and so on.
Compared with grinding equipment such as ball mill, roller mill and colloid mill, sand mill has the advantages of high production efficiency, strong continuity, low cost and high product fineness. The process conditions vary greatly and fineness can be adjusted by adding or subtracting grinding media.
The use and maintenance of the sand mill First, test 1, make preparations before the test.
2. Check if the components are firmly installed.
3, the direction of rotation of each machine should be in accordance with the direction of the arrow operation (should try the direction of the test).
4, check whether the cooling water is smooth.
5. The triangle belt adjustment is suitable for restarting. After 50 hours of work, it is adjusted again.
6. Add grinding media from the top of the barrel.
7. Start the feed pump first, and enter the material to be screened and discharged before starting the host.
8. After stopping for a long time, when it is restarted, it is often because the solid particles in the material and the grinding medium are settled to “tighten†the disperser, especially when the viscous material is at a lower temperature, the “brake†phenomenon is particularly serious. At this time, when the jog motor cannot be started, the hand is used to assist the spindle pulley “rotating the disc†to input a small amount of solvent having the capability of dissolving the material, so that the material is loosened and loosened before starting. In short, it cannot be forced to start, so as not to damage the electrical appliances and the body.
9. If the parking time is long, clean the materials in the sieve.
10. The disperser can only be rotated slightly and intermittently, because the disperser and the grinding media can quickly wear and break in the cleaning fluid.
11. When using the new grinding media, sifting should be carried out to remove foreign materials such as impurity fragments.
Second, fault 1, feed pump does not start or stop during work:
A: The power is on; B: The fuse is blown.
2, the host can not start or stop during work:
A: Whether the fuse is blown; B: Whether the feed pump feeds;
C: Whether the triangle belt is too loose; D: Whether the diffuser is stuck.
3, the motor load is too large:
A: Is the material viscosity too high?
B: Whether the grinding media is too much;
C: Is the electrical wiring normal?
4, feed pump does not feed:
A: whether the pipeline leaks; B: whether the feed pipe is blocked;
C: The feed pump has been seriously worn; D: The material viscosity is too high.
5, production efficiency decline:
A: Is the grinding medium too small?
B: The disperser has been excessively worn;
C: Whether or not the grinding media is broken in a large amount.
