Product Introduction
Overview
The Dual-Power Pin Mill is a high-efficiency ultrafine grinding machine. Its core feature is two sets of pin discs in the grinding chamber rotating at high speed in opposite directions, with a maximum relative linear velocity of up to 250 m/s. With this exceptionally high impact velocity, the equipment can easily meet the ultrafine grinding requirements of difficult-to-process materials, including crystalline and needle-shaped particles, as well as wet, high-oil-content, and highly viscous materials.
Working Principle
This machine is an impact grinding device. In the dual-rotor wide-chamber pin mill, materials are subjected to the intense impact, shearing, and friction generated by two sets of oppositely rotating pin discs, achieving rapid particle size reduction. The continuous centrifugal force field generated by the relative motion of the pin discs prevents materials from easily adhering to the chamber wall, ensuring a continuous and efficient grinding process.
Technical Advantages
-
Ultra-Fine Grinding
With a relative speed between the two discs of up to 250 m/s, it enables ultrafine grinding, achieving a finished product fineness as low as D90 ≤ 5 μm (i.e., 90% of particles have a size of 5 microns or less). -
Screenless Design for Complex Materials
No screen is required, fundamentally eliminating screen blockage caused by wet, oily, and viscous materials, making it an ideal choice for processing high-oil-content, highly viscous, and high-moisture materials. -
Efficient Heat Dissipation to Prevent Adhesion and Buildup
The spacious grinding chamber provides ample space for dissipating heat generated during high-speed operation, effectively reducing the chamber temperature while preventing materials from adhering and accumulating due to overheating. -
Optional Low-Temperature Grinding Mode
The equipment can be connected to a cooling medium, such as liquid nitrogen or cooling water, for low-temperature grinding, making it particularly suitable for processing heat-sensitive, low-melting-point, or easily oxidized materials. -
Fully Enclosed, Dust-Free Operation with Extremely High Yield
The system operates in a fully enclosed manner with no dust leakage, meeting environmental protection and production safety requirements; material yield can reach 100%, with no loss. -
Convenient Cleaning and Simple Maintenance
The mill door can be opened without special tools, and the spacious grinding chamber makes cleaning, inspection, and replacement of components highly convenient, effectively avoiding the risk of internal coating residue and blockage. -
Significantly Reduced Energy Consumption
For certain materials, energy consumption can be reduced by more than 50% compared with conventional grinding methods, significantly saving operating costs. -
Flexible Process Adjustment
Parameters such as pin disc speed, rotation direction, system airflow, and feed rate can be freely adjusted according to material characteristics and target fineness; cooling media are also supported to meet diverse and customized grinding process requirements.
