The overflow ball mill is an efficient grinding equipment that achieves material crushing and grinding through a rotating cylinder. Its core structure includes the cylinder, feeding part, discharging part, transmission part, and support device. During operation, the cylinder rotates horizontally, lifting the grinding media (steel balls) to a certain height before dropping them, crushing the material through impact and grinding actions. The slurry is finally discharged by overflow. This equipment is widely used in mining, building materials, chemical industries, and is a key device for ultra-fine material processing.
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 clinker, and classification treatment of concrete aggregates.
3. Chemical Industry: Dispersion grinding of materials such as pigments and fillers to achieve high fineness processing.
4. Ore Dressing Process: Used in conjunction with grid ball mills for the second stage fine grinding in two-stage grinding.
Product Features
1. Overflow Discharge Method: Slurry freely overflows without the need for discharge grates, reducing blockage risk and suitable for fine particle processing (different from grid ball mills).
2. High Output and Energy-saving Design: Optimized gear transmission system (such as the yellow gear in the picture) reduces energy consumption by more than 15%.
3. Stable and Reliable: The cylinder is welded with thick steel plates, support rollers distribute the load, enabling continuous operation for over 300 hours.
4. Easy Maintenance: Hollow shaft neck uses wear-resistant liners, extending the life of wear parts by 30%, and integrated lubrication system design (lubrication pipelines visible in the picture).
5. Strong Adaptability: Can handle clay ores with high moisture content, supporting wet processing.
Product Functions
1. Efficient Grinding: By optimizing cylinder rotation speed and media filling rate, material particle size is reduced from millimeter level to micron level.
2. Particle Size Control: Overflow discharge automatically achieves classification, fine particles overflow first, coarse particles return for further grinding, ensuring uniform product particle size.
3. Continuous Operation: Spiral feeding at the feeding part and overflow at the discharging part work together to achieve uninterrupted material processing.
4. Intelligent Monitoring: Can integrate variable frequency speed control, temperature monitoring, and other systems for real-time adjustment of operating parameters.
5. Environmentally Friendly Operation: Wet processing reduces dust pollution, with noise levels below 85 decibels.
Note: Technical parameters such as cylinder size, processing capacity, and motor power need to be customized according to specific models.
