XZM Ultrafine Grinding Mill
Input Size: ≤20mm
Capacity: 0.5-25 T/H
XZM series ultrafine mill are a ideal milling machine with advanced technology, which could produce 325mesh to 3000mesh with single classification. Its inner structure is relatively simple, which compromises the less downtime and easy for maintenance. The classifier is equipped with VFD to easy adjust the rotary speed of classification rotor, which makes convenient to get the requested powder size by setting on electric control panel. The produced mineral powders are widely used in paint, PVC, plastic, paper, chemical industries.
The product fineness of XZM Ultrafine Grinding Mill can be adjusted arbitrarily between 325 meshes and 2500 meshes, and can reach D97 < 5 micron at one time.
To produce same powder under the same power, the XZM is 40% higher on efficiency and 70% lower on energy consumption than air-flow mill and stirring mill.
There are no rolling bearings and screw in the grinding chamber. There is no problem of bearing and seal vulnerability and the hidden danger of screw loosening destroying.
XZM Ultrafine Grinding Mill adopts high-efficiency pulse dust collector and muffler. It has no dust pollution and noise pollution and fully meets the national environmental protection standards.
We offer customized EPC turnkey grinding engineering services, providing end-to-end guidance—from initial project initiation and process design to final commissioning—supported by a professional design institute team, thereby meeting the construction requirements for integrated sand and powder production lines.
Prioritize the investigation of the following three core causes: first, a wide variation in feed particle size combined with the presence of metallic foreign particles, which leads to instability of the material bed; second, a mismatch between the hydraulic loading pressure and the hardness of the material; third, an imbalance in the system's air flow rate, resulting in an excessively thin or thick material bed; these issues can be rapidly mitigated by adjusting the feeding rate, pressure, and air flow parameters accordingly.
Utilizing the material-bed extrusion crushing principle, this system achieves a grinding efficiency 1.65 times that of a ball mill, reduces power consumption by approximately 30%, and features high equipment integration—eliminating the need for multiple auxiliary units—thereby significantly lowering overall operational energy consumption.
It is widely used in applications such as the preparation of specialized aggregates for dry-mixed mortar, large-scale production of high-quality sand and gravel, pre-milling of ores in metallurgy and mining operations, preparation of pulverized coal for blast furnace injection, and resource recovery from industrial waste residues, spanning multiple industries including building materials, metallurgy, and chemical engineering.
The main motor drives the grinding disc to rotate, causing the material to enter the grinding roller compression zone under the action of centrifugal force. The material undergoes grinding via inter-particle crushing within the material bed; the crushed material is then graded by external classification equipment, with oversized particles recirculated for further grinding, ultimately yielding qualified sand powder.
It is suitable for processing brittle materials with a Mohs hardness below 7, compressive strength below 260 MPa, and non-flammable, non-explosive, and non-corrosive properties; it covers dozens of common ores, including limestone, quartz, granite, coal gangue, dolomite, and others.
