1. Process demand analysis

Ceramic raw material grinding has special requirements of high hardness and low pollution. When the production capacity demand is 1 ton/hour, the following parameters need to be considered:

Raw material characteristics: Alumina lining is recommended for ceramic powders with Mohs hardness of 7-8

Fineness requirement: d97≤10μm requires a classification system

Energy consumption standard: Dry grinding power should be controlled at 45-55kW·h/t

2. Key indicators for equipment selection

It is recommended to use MQG2740 model ball mill, with specific parameter configuration:

Cylinder size: φ2.7×4.0m (aspect ratio 1.48:1)

Working speed: 18-22r/min (75%-85% of critical speed)

Loading capacity: 12-15 tons of zirconia grinding media (filling rate 40%-45%)

Drive system: 132kW variable frequency motor + planetary reducer

Cooling system: Cylinder jacket water cooling device (temperature control ≤60℃)

3. Supporting system design

Feeding system: Electromagnetic vibrating feeder (GZ5 type, processing capacity 1.2-1.5t/h)

Dust removal system: Pulse bag dust collector (filtration area ≥120㎡)

Classification system: Optional turbine airflow classifier (processing capacity 1.2t/h)

4. Economic evaluation

The total investment of the equipment is about 100,000 US dollars, and the unit energy consumption is 18%-22% lower than that of traditional equipment, and the grinding medium loss is ≤0.8kg/t. It is recommended to adopt an intermittent operation mode, and the processing time of each batch is controlled at 3.5-4 hours, which can take into account both energy consumption and economy.
