Feature Overview
The spiral tower mill is a proven multipurpose type with many
advantages over conventional ball mills.
The maximum feed particle size of spiral tower mill can reach 6mm,
and the particle size of grinding product can reach less than 20
microns. The standard specification ranges from 11kW to 5222kW.
High-Efficiency and Energy-saving Grinding
The spiral tower mill is recognized as an energy-efficient grinding
equipment. The grinding efficiency is higher than that of the ball
mill, with the maximum feeding particle size of 6mm and the product
particle size of less than 20 microns. In addition to grinding
efficiency, it also has the characteristics of low consumption of
grinding medium, low installation cost, low maintenance
requirements and low liner wear. Therefore, Vang Vieng spiral tower
mill has a low total operation cost in many applications and can
continuously improve the profitability of the concentrator.
Main Features
♦ Magnetic Cylinder Liner – Permanent Solution.
♦ Bearing automatic greasing device.
♦ Simple automatic process control.
♦ Good operating flexibility for 20% power consumption makes it
ideal for regrinding and other high converter applications.
♦ High-efficiency high-torque motor.
