I. Working Principle of Vertical Mills
Vertical mills are widely used grinding equipment. Their operation primarily involves an electric motor driving a reducer, which in turn rotates the grinding disc and rollers. Under centrifugal force, materials are flung to the periphery of the grinding disc, where they undergo grinding between the rollers and disc. A classifier separates the fine powder, while coarse particles return to the grinding disc for reprocessing. This cycle continues until the desired fineness is achieved.
II. Technical Features
1. High Efficiency & Energy Savings: Utilizing aerodynamic and mechanical transmission principles, the vertical mill achieves low-energy, high-efficiency grinding operations.
2. Controllable Fineness: The classifier grades ground materials, enabling precise control over particle size distribution.
3. High Automation: Equipped with automated control systems, it supports remote monitoring and intelligent operation to enhance production efficiency.
4. Compact Structure: With a small footprint and streamlined design, the vertical mill significantly reduces factory construction costs.
5. Easy Maintenance: Its modular design facilitates quick and convenient maintenance, substantially lowering upkeep expenses.
III. Application Scenarios
The 20-50 ton/hour water slag fine powder vertical mill is primarily used in cement, metallurgy, chemical, and power industries. These sectors require large-scale production of powdered materials with varying fineness, such as grinding limestone and gypsum in cement production, grinding iron ore and non-ferrous metal ores in metallurgy, grinding barite and fluorite in chemicals, and preparing coal powder in power generation. Vertical mills play a vital role in these fields, offering significant advantages in substantially improving production efficiency, reducing energy consumption, and minimizing environmental pollution.
IV. Technical Advantages of SBM Vertical Mills in Water Slag Processing
1. Technological Leadership with Low Investment Costs
SBM vertical mills integrate crushing, grinding, drying, classification, and conveying into a single unit. They support direct hot air feeding, feature compact layouts, and can be installed outdoors, significantly reducing investment expenses.
2. High Grinding Efficiency and Superior Product Quality
The unique roller-disk structure design incorporates a hydraulic automatic pressure adjustment system for rollers, maximizing grinding surface area and powder efficiency. The finished product exhibits uniform particle size distribution, high quality, and enhanced reactivity.
3. Reliable Quality and Stable Operation
The transmission system employs advanced planetary gear reducers for high load capacity and stable operation. Hydraulic pressure systems and limit switches prevent direct contact between grinding rollers and discs, minimizing vibration. Automatic slag discharge ensures safe equipment operation.
4. High Drying Capacity, Wide Adaptability
Air inlet temperature is controlled based on finished powder moisture requirements and raw material moisture content. Utilizing hot air for material conveyance, it accommodates feed moisture ≤15%, offering broad adaptability and making it the preferred choice for bentonite powder production.
5. High Automation Level
The SBM vertical mill employs an automated control system enabling remote operation, interlock protection, reliable performance, and simplified operation. This reduces operator workload and enhances efficiency.
6. Easy Maintenance, Low Operating Costs
Rollers utilize forced oil lubrication and are equipped with a hydraulic roller tilting device. During maintenance, the hydraulic system tilts the rollers out of the machine, providing ample access space without requiring disassembly—ensuring quick and convenient servicing.
7. Energy-Efficient, Low-Consumption, and Environmentally Friendly
Continuously optimized grinding technology and process design ensure the entire production line operates with minimal noise, low energy consumption, and no dust leakage, meeting the latest national environmental protection requirements.
