Product details
The CXM ultrafine ring roller mill is a newly developed ultrafine grinding equipment by Zhida Heavy Industry based on years of production and research and development experience. The machine has comprehensive mechanical crushing performance such as rolling, grinding, and impact, and is widely used for ultrafine grinding of various non-metallic minerals with Mohs hardness below 7 and humidity below 6%, such as talc, calcite, calcium carbonate, dolomite, potassium feldspar, bentonite, kaolin, graphite, carbon, etc. It is a truly efficient, energy-saving, and particularly suitable ultrafine grinding equipment for deep processing of non-metallic minerals.
Product advantages
1. It has the advantages of high fineness, high yield, low energy consumption, and low investment. The crushing capacity of the HCH ultrafine ring roller mill is more than twice that of similar equipment.
2. The equipment system is complete and can simultaneously complete the two processes of ultrafine grinding and ultrafine classification.
3. The fineness of the finished product can be adjusted freely between 0.04-0.005mm (400-2500 mesh), and the products produced with different fineness can better meet market demand and improve the competitiveness of the enterprise.
4. Environmentally friendly production: The equipment operates with low noise, high dust removal efficiency, and no dust pollution.
5. The equipment installation is very convenient and does not require large-scale civil engineering projects. Once the equipment is installed, it can be put into production immediately.
6. The equipment runs smoothly, has reliable performance, can produce continuously and normally, has high precision in product fineness grading, and good product quality.
7. Low wear: The vulnerable parts are made of special wear-resistant materials, which effectively extend their service life.

Working principle
Material managementcrusherCrushed into materials smaller than 10 (mm), lifted to the storage hopper by a bucket elevator, and then quantitatively fed into the main machine cavity for grinding by an electromagnetic vibration feeder. The grinding roller installed on the turntable in the main machine cavity rotates around the central axis, and there is a large movable gap between the grinding roller and the grinding roller shaft. Under the action of centrifugal force, the grinding roller swings horizontally outward, causing the grinding roller to press the grinding ring, and the grinding roller rotates around the grinding roller shaft at the same time. The material is crushed and ground through the gap between the grinding roller and the grinding ring due to the rolling of the grinding roller. The grinding roller is arranged in 4 layers, and the material is first crushed between the first layer of grinding roller and the grinding ring, and then crushed through the second, third, and fourth layers. Therefore, the material is fully crushed and ground, and the resulting product has a fine fineness.
The ground powder falls onto the chassis due to gravity and is blown by the airflow of the blower to the classifier above the main machine for screening. Those that are too fine or too coarse still fall into the main machine for regrinding, while those that meet the specifications flow into the pulse dust collector with the wind. After collection, they are discharged through the discharge valve to obtain the finished product. The purified airflow flows into the blower through the residual air duct above the pulse dust collector, and the air path is circulating. Except for the positive pressure from the blower to the grinding room, the airflow in other pipelines flows under negative pressure, and the indoor hygiene conditions are good. Due to the moisture contained in the material evaporating into gas during grinding, the gas leaked into the flange joints, feed ports, and other locations in the pipeline increases the air volume in the circulation air path. These increased air volumes are discharged into the atmosphere through the air box interface between the blower and the host.
