SPECIALIST MILLING TECHNOLOGY UPGRADED FOR THE FINE GRINDING OF ABRASIVE RAW MATERIALS
A patented milling system has been upgraded with special wear resistance linings and other improvements to meet the demanding fine grinding requirements of abrasive raw materials.
The UK-based International Innovative Technologies Ltd (IIT) has pioneered a vertical milling system for the fine grinding of a wide range of powders, bulk materials and industrial products.
These include aluminium oxide, silicon carbide and zirconia, fly ash and different types of slag, as well as high purity quartz, calcium carbonate, other minerals and coal.
Compact and powerful, the highly energy efficient IIT m-series mills have the capability to produce all grades of material down to very fine powders of sub 10 microns and with the ability to meet tight particle distribution specifications.
The latest rugged and durable version of the mill incorporates a number of special features designed to both reduce wear caused by hard materials and eliminate the dangers of contamination.
The centrifugal grinding mechanism of the m-series is extremely efficient with the vertical material flow path and special roller assembly ensuring that the force produced is translated into maximum particle grinding power.
To meet the specific requirements of demanding industrial applications and hard minerals, this feature has been further enhanced with a range of material options for the grinding rollers and rings, including abrasion resistant tool steels, high chrome iron and ceramic tooling.
The main grinding module body is now manufactured from heavy duty austempered ductile cast iron and internal wear resistant polyurethane coatings have been incorporated in the inlet and outlet feeds. A ceramic tile lining can also be used in the grinding module itself for effective long life wear protection and the avoidance of contamination.
The new milling system also incorporates pressurised oil cooling and lubrication for extended bearing life, enhanced sealing integrity and the cooling of critical assemblies. In addition, systems can also be provided with forced air circulation through the mill for product cooling and moisture removal where necessary.
The new upgraded system comes in a range of modular grinding options to meet the needs of different materials, particle size requirements and throughput volumes.
These options include a special twin mill system configuration, utilising two grinding modules operating in parallel from a common feed. Grinding modules can also be arranged vertically in series for multi-stage milling cycles for the production of certain grades of material.
In the twin mill configuration, each milling unit operates independently and can therefore easily be taken offline for repair or service periods. Simple engineering access, break down and reassembly features enable fast in-line maintenance and replacement of the grinding modules when necessary.
Fully integrated electronic control and process monitoring systems for the IIT technology have been developed in close collaboration with Siemens Industry in the UK. Siemens motors, drives and control and instrumentation systems are an integral part of the IIT milling and processing systems.
For complete abrasive material handling solutions, the m-series fine grinding technology can be linked with IIT’s c-series classifiers and s-series cyclones for effective close control of particle size distribution. More details at www.iituk.com
