Table of Contents
Calcite ultrafine vertical grinding mills are a new type of ultra-fine industrial ore grinding equipment that integrates grinding, grading, powder collection and conveying.
It has high grinding efficiency, low energy consumption, uniform particle shape, narrow particle size distribution, good fluidity, and strong product adaptability. It is an ideal non-metallic ores powder making equipment.
1. The finished powder has strong diversity and high added value
The main machine is equipped with a high-efficiency multi-rotor powder concentrator, the finished product has a wide range of particle size, 2um powder content up to 70%, D97=4-5um, specific surface area 21000cm2/g, the main machine powder can reach D97=8.5um for two times The powder selection system can choose 4-5um powder.
The finished powder has a narrow particle size distribution, adjustable 2um content, good particle shape, and high added value of the finished product.
2. High grinding efficiency and low power consumption
The optimized design of grinding rollers, grinding discs and internal airflow guidance greatly improves the grinding efficiency. The productivity is 30% higher than similar products, and the power consumption is 30%-60% lower than that of the ball mill.
3. Intelligent control system, stable and efficient operation
The internal uses PLC intelligent control, the external uses the touch screen to display and adjust the system parameters in real time. Modular excuses are reserved, and the scalability is strong, which can quickly realize the connection of the front-end grinding aid adding system, the back-end powder modification system and the packaging system to ensure the automatic control of the entire process.
4. Long service life and low maintenance cost
The wear-resistant parts of the main engine are made of high-wear-resistant synthetic steel, which effectively prolongs the service life of the wear-resistant parts, reduces the iron content of the finished product, and reduces maintenance costs.
5. Green Environmental protection
With the new structure design and the principle of grinding, the equipment has low vibration and low noise.
The equipment is sealed as a whole, the system works under negative pressure, and the dust points are controlled by pulse dust collectors, no dust spills, and environmentally friendly and clean.
The main engine of Calcite ultrafine vertical grinding mill is mainly composed of motor, reducer, machine body, grinding roller device, grinding disc device, pressurizing device, powder separator, lubricating station, hydraulic station, etc.
4. The grinding roller and the grinding disc are not in contact, and the mechanical limit device is adopted to avoid damage, impact and vibration
5. The multi-rotor high-efficiency cage powder separator has high powder separation efficiency and is easy to adjust and control, and can quickly produce a variety of finished products
1. Grinding rollers and discs are made of highly wear-resistant materials, with long service life and low maintenance costs
2. The grinding zone between the grinding roller and the grinding disc adopts a special grinding curve design to ensure the stable operation of the host and effective grinding
3. The pressure of the grinding roller adopts a hydraulic tension rod with adjustable elastic coefficient to ensure the continuous pressure of the grinding roller on the material
The main motor drives the grinding disc to rotate through the reducer.
The materials fall into the center of the grinding disc through the elevator, screw conveyor, star-shaped feeding valve, and feeding screw, and move to the edge of the grinding disc under the action of centrifugal force. When passing through the grinding zone between the grinding roller and the grinding disc, it is crushed by the pressure of the grinding roller and the shearing force between the grinding disc and the grinding roller.
The pulverized material continues to move to the edge of the grinding disc until it is brought into the multi-rotor powder concentrator at high speed by the airflow from the high-pressure fan on the edge of the grinding disc for classification.
The powder that does not meet the requirements falls into the grinding disc and re-grinds. The powder that meets the requirements is collected by the airflow into the dust collector, and sent to the finished product warehouse by the lifting system or the pneumatic conveying system.
| Product name | Product performance | Equipment performance |
|---|---|---|
| Raymond mill | 2um content is about 6% or more, the highest fineness is 45um, low-end finished powder. | Production of coarse powder and general fine powder above 45um, stable operation, high cost performance and high noise. |
| Ring roller mill | 2um content is about 20% or more, the highest fineness is 8-10um, middle and high-end finished powder. | Produce 10-15um powder, stable operation, short life of wearing parts, high noise and low output. |
| Ball mill | Generally produce 45um thick body; ultra-fine ball mill can produce 10um powder; ceramic ball mill has high whiteness and the lowest iron content. Good grain, spherical. |
It is suitable for a wide range of materials, a wide range of particle size of the finished product, a wide selection of grinding media, high energy consumption and high noise. Producing different specifications of powder, long switching time. Difficulty in fineness adjustment. |
| Jet mill | 5um powder can be produced, jet pulverization, the whiteness of the finished powder is the best. High-end food grade finished powder. |
Mechanically crushed, the powder has the highest fineness. It is only suitable for high-end or high value-added powders. High energy consumption and low output. |
| Ultrafine vertical grinding mill | The content of 2um is 30%-70%, D97=4-45um, the fineness of powder can reach 8.5um at one time, and the specific surface area is high | There is no contact between the roller and disc, the vibration is small, and the operation is stable. Low energy consumption and large output. The production of finished products of different specifications can realize rapid switching. The products are highly professional, and the initial investment is relatively large. |
