Brazilian High Purity Agate Grinding Balls
Product Details
Product Introduction
It is made of imported agate raw material. It not only has high strength and toughness, but also high wear resistance. Can be used in all kinds of ball mill, long life and can reduce the cost, reduce the wear of the ball in the production and processing,the impact on the environment is small.

Number and Size of the Balls
1. Pregrinding the coarse, hard material with large balls 2. Use of many small balls will increase the fine fraction if the running time is increased 3. A higher mass (spec. weight) of the grinding balls will accelerate the grinding 4. Size of the Grinding Balls | |
Type of feed material | Ball diameter |
Hard samples feed particle size <10 mm | 30 mm or 40 mm |
Medium piece size (<5 mm) | 20 mm |
Fine material (0.5 mm) | 10 mm or 5 mm |
Homogenisation of dry or liquid samples | 10 mm |
Homogenisation of viscous samples | 20 mm |
These are just clues: the size of grinding jars and grinding balls should be determined experimentally if necessary. | |
Advantages
* A large, high strength, high grinding efficiency, will shorten the processing time.
* Ball really high, smooth surface, the distribution of small diameter, high-precision products can be broken and scattered.
* The use of high purity raw materials to a high wear resistance, minimal limits of impurities mixed.
* Good wear resistance, long life, without frequent added agate grinding ball, reduce production costs.
* Significant than viscous and the smashing of wet grinding and dispersion, may also play a greater power.
* Stir in the use of the ball mill grinding process, need not worry about the ball rust corrosion.
Application
* Piezoelectric ceramics, insulation materials, electronic materials, magnetic materials and scattered smash.
* Paint, ink (ink), paint, and the crush spread.
* Medicines, food and smash.
* Precision Ceramics dispersed and decentralized smash.
* Other: chemical, electronics, ceramics, ink, paint and other mechanical grinding supporting the ideal grinding media.
Note the Use of Agate Grinding Balls
1. According to the viscosity grinding materials, hardness, ball mill capacity to divert grinding and particle size, choose varieties accordingly, specifications and quantities of agate beads.
2. Before grinding, polishing and cleaning agate beads tube wall; Cleaning can use water, or brine manual cleaning methods.
3. First to grinding materials into grinding machine tube and then into modest agate beads. After grinding machine running,gradually inserted agate beads. According to fill in the proportion of grinding and polishing materials density to fill. The volume for grinding cylinder is 65% -75%.
4. Never agate beads grinding machine shut in the long run under the conditions. Otherwise, agate beads in high-speed operation of the grinding machines easily smashed.
5. Grinding machine running for some time, to add appropriate agate beads, in order to ensure the quality and effectiveness of grinding.
