Instruction:
Choosing the appropriate variety,standard and quantity glass beads according to the viscosity,hardness, dispersed particle size of grinding materials(abrasive materials) and grinding requirements.
Before grinding,clean the glass beads and grinding machine barrel inner wall
First put the materials need to be ground into the grind machine barrel,then put into right quantity glass bead. After the grinding machine running,gradually add the glass beads. Usually the filling quantity is 70%-85% of the grinding machine barrel volume.
Do not make the glass beads operate for a long time in the condition of the grinding machine are lake of materials.Or the glass beads will be mashed easily in the high speed operating grinding machine.
Adding glass beads properly after operating for a period to guarantee the grinding quality and efficiency.
