High-pressure Micro-powder Mill

Feed particle size:≤15-≤25mm Processing capacity:0.2-21t

Applicable Materials:Kaolin, limestone, calcite, talc, marble, barite, gypsum, iron oxide red, iron oxide green, aluminum hydroxide, pigments, bentonite, clay, coal, activated carbon, carbon black, etc.

Application Scope:Processing of materials in industries such as metallurgy, building materials, chemicals, mining, agriculture, and chemical engineering.

The high-pressure grinding mill is suitable for the fine grinding of over 280 materials in industries such as mining, metallurgy, chemical engineering, and building materials, including barite, limestone, ceramics, and slag. These materials must have a Mohs hardness of no more than 9.3, a humidity level below 6%, and be non-flammable and non-explosive. The finished product's particle size can be adjusted within the range of 80-425 mesh (with a minimum of 1000 mesh). By adding a special device inside the machine, it can also produce coarse powder with a particle size of 30-80 mesh.

Structural Features of High-Pressure Micro Powder Mill

The high-pressure mill mainly consists of a main machine, a blower, an ultra-fine analyzer, a finished cyclone powder collector, a bag filter, and connecting air duct pipes. Based on user requirements, auxiliary equipment such as an elevator, storage bin, electrical control cabinet, feeder, and crusher can be equipped. Inside the grinding chamber of the micro-powder mill, the roller assembly is suspended on the roller hanger frame through a horizontal shaft. The roller hanger frame is fixedly connected to the main shaft and the scraper holder. The pressure spring tightly presses against the outer cantilever end of the roller bearing housing via a tension rod. Using the horizontal shaft as a support point, the spring pressure forces the grinding roller to press tightly against the inner circular surface of the grinding ring. When the motor drives the transmission device, the scraper mounted on the scraper holder rotates synchronously with the grinding roller. The grinding roller rolls along the inner circular surface of the grinding ring while rotating on its own axis. The analyzer drives the rotation of its impeller through the motor transmission device, and the speed adjustment of the analyzer determines the fineness of the output powder.

Performance Characteristics of High-Pressure Micro Powder Mill

1. It has a wider range of applications compared to jet mills.

2. Compared with other similar mills, the grinding pressure of the roller on the material is increased by 800-1200 kg under the action of the high-pressure spring.

3. Energy-saving: Under the same output and fineness, the system energy consumption is only one-third of that of an air jet mill.

4. Low investment, high returns. Under the same output and fineness conditions, its price is only one-eighth that of an air jet mill.

5. Large feed particle size, with the average particle size of the discharged material reaching ultrafine powder of 6.5um in a single pass.

6. Overlapping multi-stage sealing and grinding device, with excellent sealing performance.

7. The dust removal effect fully meets the national dust emission standards.
