Industry Leading Company of Vertical Stirred Mills

For over 60 years of experience in the mineral processing industry, CITIC Heavy Industries (CITIC HIC) has been always committed to increase the grinding efficiency of minerals by constantly searching for ways to improve and develop energy-saving high-efficiency ore grinding equipment. CSM series vertical stirred mill was jointly developed by a combined R&D team of foreign and domestic experts. With independent intellectual property right, this vertical stirred mill is an ideal wet grinding solution for global customers who are looking for safe, reliable and energy efficient stirred milling machines.

Features of Vertical Stirred Mill

Vertical stirred mills are a fine grinding equipment that covers advantages of low rotation speed, high reliability and long life cycle. The significant advantages that the vertical stirred mills have over the ball mills are smaller size, less auxiliary equipment required, more simple system and more options of processing methods. Powder flow behaves continuously in the stirred mill, and it can be operated in both open- and closed-circuit operation.
Vertical stirred mills are also characterized by low noise, vibration and heat that are generated. The grinding media moves orderly in the vertically stirred media mill thereby resulting in more efficiency on grinding performance and much less power consumption. Since it is operated with wet grinding method, the vertical stirred mill does not require any cooling system due to the low speed operation.
In addition, vertical stirred mill features a small footprint without any external rotating parts. The helical agitator achieves the force balance, enabling the foundation to bear only the combined forces of mill, slurry and grinding media. This simple foundation contributes in a short installation period.

Investment Cost Small footprint No any external rotating parts Less auxiliary equipment required Simple foundation Easy installation, short installation period Operation & Maintenance High efficiency, energy saving Low wear ratio, less cost Minimal maintenance More Advantages Strong adaptability to ore characteristics Adjustable fineness of grind Good normal distribution More options of system Low rotation speed, high reliability Low low noise, vibration and heat Why Choose CITIC HIC's Vertical Stirred Mill High cost-effectiveness

Providing the best solution of vertical stirred mill selection through minerals testing, process simulation and optimization

Vertical stirred mill test Levin test Bond work index test JKSimMet simulation software Simulation With finite element analysis modeling, simulation analysis of coupling behavior between particle and fluid is carried out to optimize equipment operating parameters thereby increasing grinding efficiency. Strength Finite element analysis is employed for strength calculation of helical agitator, transmission shaft, barrel and upper body to identify the optimal structure, and seismic analysis is performed to ensure the reliability of the stirred mill. Transmission Three transmission modes are available according to the motor power:
Direct starting with squirrel cage motor
Variable frequency starting with VFD
Liquid resistance soft starting with wound rotor motor Auxiliary equipment Our vertical stirred mill can be configured with helical path unit, jacking system, spiral conveyor, hydraulic wrench, grinding media adding unit, etc. Control PLC system is adopted to achieve low-pressure control and system protection. Monitoring system is used to visually inform the operator of the system status including temperature, pressure, flow rate, pressure difference and vibration rate via touc screen display.
