Technical Advantages

High Efficiency &High Quality of Finished Products

The grinding curves of the roller shell and lining plate are uniquely designed based on the ultrafine pulverization principle, which makes it easier to form material bed, improving the grinding efficiency and increasing the proportion of finished products from the primary grinding.

Advanced Separation Technology ＆ Energy Efficiency

The principle of multi-rotor powder classifiers is adopted, so the finished product fineness can be customized as selected range , with no low-grade material in existence. By adopting PLC control system, major parameters like grinding pressure, rotating speed of grinding disc and speed of classifier etc.

Intelligentized Control System ＆ Stable Operation

The control mode for pressure adjustment of grinding roller adopts PLC/DCS automatic control system, which ensures the accurate control of grinding pressure, high efficiency and stable operation. Automatic control system enables remote control and simple operation. Frequency-conversion speed regulation enables the mill to be used for materials.

Environmentally-friendly

Special structural design and operating principle of the mill ensure small vibration and low noise. The whole equipment is well sealed and the system operates under negative pressure. Therefore, powder and dust are prevented from flowing out of the system. It is environmentally-friendly and meets the national environmental protection requirements.

The ultrafine vertical mill has a wide range of applications in various industries due to its ability to produce high-quality, ultra-fine powders of various materials. Some of the common application fields of the ultrafine vertical mill are:

1. Pharmaceuticals: The ultrafine vertical mill is widely used in the pharmaceutical industry for the production of drugs and other medicinal products. It is used to grind and mill active ingredients, excipients, and other raw materials to create powders of a consistent particle size and shape.

2. Ceramics: The ultrafine vertical mill is used in the ceramics industry to produce fine powders of ceramic materials, such as alumina, zirconia, and silica. These powders are then used to create high-quality ceramic products, such as tiles, tableware, and electronic components.

3. Pigments: The ultrafine vertical mill is used in the pigment industry to produce high-quality pigments with a consistent particle size and color. These pigments are used in a variety of applications, such as paints, coatings, inks, and plastics.

4. Coatings: The ultrafine vertical mill is used in the coatings industry to produce high-quality coatings with a consistent particle size and thickness. These coatings are used in a variety of applications, such as automotive coatings, marine coatings, and industrial coatings.

5. Adhesives: The ultrafine vertical mill is used in the adhesive industry to produce fine powders of adhesive materials, such as resins and polymers. These powders are then used to create high-quality adhesives with a consistent adhesive strength and viscosity.

6. Food and beverage: The ultrafine vertical mill is used in the food and beverage industry to produce fine powders of various food ingredients, such as spices, flavors, and extracts. These powders are then used to enhance the flavor and aroma of food products.

7. Mining and minerals: The ultrafine vertical mill is used in the mining and minerals industry to produce ultra-fine powders of various minerals, such as gold, silver, and copper. These powders are then used in various applications, such as ore processing and metallurgy.

Components of Ultrafine Vertical Mill

1. Grinding chamber: The grinding chamber is the heart of the machine where the grinding beads and materials collide to produce ultra-fine powders. It is typically cylindrical in shape and is lined with wear-resistant material to protect it from damage.

2. Agitator: The agitator is responsible for moving the grinding beads around the chamber, creating a high-speed and high-pressure airflow in the chamber. It is typically a rotating shaft with paddles or arms attached to it.

3. Feed inlet: The feed inlet is where the materials are introduced into the chamber. It is typically located at the top of the machine and is designed to provide a steady flow of materials into the grinding chamber.

4. Discharge outlet: The discharge outlet is where the finished powders are collected. It is typically located at the bottom of the machine and is designed to allow the powders to exit the chamber while keeping the grinding beads inside.

5. Motor: The motor provides the power to the machine, driving the agitator and maintaining the pressure and speed in the grinding chamber. It is typically an electric motor that is connected to the agitator shaft.

6. Control system: The control system is responsible for monitoring and controlling various parameters of the machine, including the speed and pressure of the airflow, the size of the grinding beads, and the feed rate of the materials. It is typically a computer-based system that allows for precise control of the machine's operation.

7. Cooling system: The cooling system is responsible for maintaining the temperature of the machine and preventing overheating. It typically consists of a water-cooled jacket that surrounds the grinding chamber.

Each of these components plays a critical role in the operation of the ultrafine vertical mill, and they must work together in harmony to produce high-quality, ultra-fine powders.

Working Principle

The materials drop on the grinding plate center through the screw feeder and evenly move outwards under the action of centrifugal force of the rotating grinding plate driven by the reducer; Large materials are crushed and ground by the grinding rollers when passing through the grinding area, while smaller materials form a material bed by extrusion for further inter granular crushing. The crushed materials continue to move towards the mill edge until being taken into the classifier by the air flow from the air inlet. The powder particles failing to meet the particle size requirement fall back on the grinding plate for further grinding while the qualified powder particles are collected in the pulse dust collector with the air flow and discharged as finished products. However, the iron blocks and other sundries mixed in the materials move along with the materials towards the edge of the grinding plate due to their own weight. They fall into the lower chamber of the mill and then be discharged out of the mill through the slag discharge opening by the scraping plate.
