Pls first check the technical specification for our high alumina grinding media ball as the following:

1) 92% alumina grinding ball

Al2O3: 92% Min.

Fe2O3: 0.25% Max.

Mohs Hardness: 9

Water absorption: 0.02% Max.

Density: 3.60 g/cm3 Min.

EWT: 0.15 Max.

2) 95% alumina grinding ball

Al2O3: 95% Min.

Fe2O3: 0.20% Max.

Mohs Hardness: 9

Water absorption: 0.02% Max.

Density: 3.65 g/cm3 Min.

EWT: 0.10 Max.

If your grinding work mode is batch grinding, then 92% alumina grinding ball is O.K., if your grinding work mode is continuous grinding, then 95% alumina grinding ball is most recommended.

Dear Mr. Morag,

Cyclotec can provide dry quartz grinding P50 18-20 microns, and P80 45 microns

WITHOUT CLASSIFICATION

( 96% silica content, silica sand feed F80 630 microns, topsize 5 mm)

The biggest mill we have can provide 3 ton/hour capacity at mentioned above specs.

Also if to turn the product to second mill run = P50 9-10 microns, P80 25 microns

WITHOUT CLASSIFICATION

Total power consumption will be 15-18 kW/ton for each mill run

See film demo at link below

Please let me know if you need further info.

For quartz sand grinding you can choose quartz sand grinding mill,but before grinding ,you may have to crush the stone into proper size,so crusher machine are needed.

For quartz sand classifying, spiral classifier is a good choice. ■

Quartz of narrow fraction 10µm-50µm.

New data of grinding balls and mill lining consumption was obtained while grinding crystalline quartz in the PCM Leotec.

Feed material - quartz F90 = 100 microns (Kyshtym mining processing plant).

Two final products:

1. P90 = 13 microns - 85% of feed material.

2. P90 = 2.11microns - 15% of feed material.

Grinding balls consumption - 1 kg / ton of a source product.

Lining wear - 240 grams / ton.

Dear Mr. J. MORAG

Quartz is hard material (8 on Moose scale) and requiers a lot of energy while grinding. We offer best and most effective mills: continous action planetary mills. Energy consumption of grinding in the planetary mill is 20-100 times lower than in the ball or vibration mills. For example grinding of such hard material as quartz to a size P(98)=20 microns requires less than 50 kWh / tonne.

Other advantages of technology are:

• Reduction of production and capital costs. Grinding costs 5-10 times lower than any of the existing methods.

• Grinding in dry and wet modes.

• Ability of complete cleaning of the mill.

• Small size, mobility.

• Minimum need for expendables. High performance with small overall dimensions can reduce the cost of liners and grinding media.

• Sustainability, no vibrations. The mill does not require a foundation.

• The best opportunities for mechanical activation. The technology allows to change the properties of many materials, revealing their new opportunities
