The Solution To Broken Beads
A Equipment
Dispersion disc: Dispersion disc is installed backwards, loose or cracked
Separation device: There is a gap in the dynamic screen ring, and the screen is damaged
Feed Pump: After the gear pump is abruptly turned off, the pressure inside the sand mill back-presses the beads into the pump. This can be avoided as much as possible by adding a one-way valve, while maintaining regular cleaning of the feed pump
Inner cylinder: The inner cylinder has defective points
B. Production operation
Mixed use of large and small beads: This kind of situation shows signs of improving grinding efficiency at first, but with the increase of grinding time, the situation of large beads grinding small beads occurs, and then the deformation and even breaking of small beads are accelerated. The solution is to try to use beads of uniform particle size.
Mixed use of different brands of beads: Due to the inconsistent hardness and density of various beads, it is easy to cause hard beads to eat soft beads, so this form should be avoided.
The viscosity of the slurry is too thin or too thick: relative to the grinding beads of a certain density, it is so easy to cause the accumulation of the beads and the direct contact with the wear parts of the sand mill to accelerate the wear and tear of the beads
The flow of the material is too fast: This will cause the beads to accumulate at the material outlet, which will accelerate the wear of the beads and the accessories of the sand mill. The solution is to first loosen the backlogged grinding beads by intermittently starting the machine, and redistribute them evenly, and then adjust the flow of materials.
