The raw material mill is an efficient grinding equipment that achieves material crushing and grinding through a rotating cylinder. Its core structure includes the cylinder body, feeding part, discharging part, transmission part, and support device. During operation, the cylinder rotates horizontally, lifting the grinding media (steel balls or gravel) to a certain height before dropping them, crushing the material through impact and grinding, and finally discharging the fine material. This equipment is widely used in mining, building materials, chemical industries, and is a key device for achieving ultra-fine processing of raw materials.
Product Applications
1. Mining Processing: Wet fine grinding of metal ores such as gold, copper, and iron, as well as grinding of non-metallic minerals like quartz and feldspar.
2. Building Materials Production: Ultra-fine grinding of cement raw materials and concrete aggregates to enhance material reactivity.
3. Chemical Industry: Dispersive grinding of materials such as pigments and fillers to achieve high fineness processing.
4. Ore Dressing Process: Used with jaw crushers and classifiers to form a complete grinding and classification system.
Product Features
1. High Fineness Grinding: Optimized cylinder speed and media ratio, with over 90% of the output particle size reaching -200 mesh.
2. Energy Saving and Consumption Reduction: Uses variable frequency motor + gear transmission (such as the yellow gear in the picture), reducing energy consumption by 15% to 20%.
3. Stable and Reliable: Cylinder made of thick-walled steel plate welding, support rollers distribute load, continuous operation time exceeds 300 hours.
4. Easy Maintenance: Hollow shaft neck uses wear-resistant bushings, extending the life of vulnerable parts by 30%, integrated lubrication system design.
5. Strong Adaptability: Can handle clay ores with high moisture content, supports wet processing, reducing dust pollution.
Product Functions
1. Efficient Grinding: By optimizing the movement trajectory of the media, the material particle size is reduced from millimeter level to micron level.
2. Particle Size Control: Equipped with grates (in some models) or overflow weirs at the discharge end for automatic classification, ensuring uniform particle size.
3. Continuous Operation: Spiral feeder and discharge system work together to achieve uninterrupted material processing.
4. Intelligent Monitoring: Can integrate PLC control system to monitor temperature, vibration, current, and other parameters in real time.
5. Environmentally Friendly Operation: Wet processing reduces dust, noise reduction design keeps noise below 85 decibels, meeting industrial environmental standards.
