UK-based International Innovative Milling Technologies Ltd (IIT) has developed new low energy milling technology for waste glass processing applications.

The new M350 milling system extends the company’s ‘m-series’ range of vertical roller mills and allows close control of particle size distribution to meet the needs of many size reduction applications for glass powders and waste product streams.

The M350 is specifically designed to accommodate an output capacity range of up to 4.5t/hr for single pass applications and up to 500Kg/hr for finer products requiring classification.

As such it is ideal for cullet reprocessing and additionally suitable for a glass sand and powder processing applications including process validation, small tonnage batch processing, research and development, material preparation and pre-processing routines.

Accurate control of particle size distribution changes can be achieved by smooth operating adjustments to the rotational speed of the mill to provide true ‘one pass’ milling and fines control. As a result m-series mills benefit the entire plant through reduction of contaminant, and furnace build up problems.

With the growing market value of waste glass for a range of applications, the controllable operation of the M350 means output can be adjusted to deliver almost any particle size distribution required at the touch of a button.

As a result, the ability to minimise undersize or oversize components in the final milled glass powder product means plant operators can achieve required performance with single equipment sets and sieve mesh aperture changes rather than entirely different process routes or equipment combinations.
