The Atritor Dryer-Pulveriser has been in continuous manufacture for 80 years. It has a quite unique design with pulverising occurring predominantly by attrition. The mill is a very compact air-swept flash dryer and temperature differentials of over 500° C ensure high evaporative capacity and thermal efficiency.

Internal wear parts are manufactured from abrasion resistant irons produced in our own foundry. They are extremely quick and easy to change through the hinged door of the mill.

The size of the feed can be up to 50mm with grinding capacities as high as 20t/h.

The mill incorporates an integral product particle size controller for consistent product quality, which, unusually, is unaffected by processing rate.

The newly developed "B" series extends the evaporative capacity of a single unit to 6t/h. These are of lighter duty construction, designed for operation on non-abrasive materials and where drying is the major function.

An extensive range of materials are processed by these mills, examples are:

Activated bentonite
Barytes
Bentonite
Burnt lime
Cellulose acetate
Chalk
Coal
Cocoa
Coffee grounds
Dyes
Fluorspar
Industrial sludges Graphite
Iron oxides
Limestone
Paper wastes
Slaked Lime
PCC
Petroleum coke
Pigments
Sewage sludge
Starch
Talc
Ultramarine
Wood Pulp

In its facilities in Coventry, UK, Atritor produces a broad range of drying and milling equipment to serve the process industries. We are active across the spectrum of minerals, chemicals, food, pigments, pharmaceuticals, energy and waste processing operations.

From its earliest days, when the first 'Atritor' Dryer-Pulveriser was developed for the cement industry, the Company has sought to produce high quality equipment specifically for the production of fine, dry powders. The fact that we continue to maintain machines that have been in service for more than seventy years is testament to the quality of our products.

Our fully integrated quality system is audited to the strict requirements of ISO 9001. As a process engineering company we bring to you the benefit of over ninety years of unique experience in this sector. We design and build turn-key plant specifically tailored to suit your needs, for all industries. Primary machinery is manufactured in our own foundry and machine shops and we work closely with associates and specialist suppliers to provide ancillary equipment.

Our modern pilot plant is equipped with the full range of our products which we use to evaluate and optimise process parameters for full system design.
