Hammer Mill
Input Size: 0-50mm
Capacity: 8-70T/H
HM series hammer mills are a new generation of grinding equipment for producing 0-3mm coarse powder. This mill adopts a partial working priciple of crushers and makes up the disadvantage of uneven particle size of finished products in traditional coarse powder mills. Now, it has become the core equipment for production of coarse powder particles, which are widely used in dry mortar, animal feed, agriculture, construction material, etc.
Hammer Mill has the advantages of good grinding performance. It has higher output and grinding ratio.
Hammer Mill has optimized cavity design and unique operating principle. The performance of this mill is excellent and stable.
Hammer Mill has high cost-effective, simple working process. It takes only a little space, saving costs for foundation base.
The casing with high manganese steel lining has higher abrasion resistance and longer service life.
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.
