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.
