The comprehensive range of wet grinding systems from Polysius comprises of:
. Autogenous and semiautogenous mills,
. Ball mills,
. Rod mills,
. Scrubbers.
Polysius offers dry grinding systems comprising of the following equipment :
. AEROFALL type dry SAG mills,
. Dry grinding ball mills,
. Air separators,
. Dryers,
. POLYCOM® high-pressure grinding rolls.
High-pressure grinding rolls can be supplied to work in dry grinding as well as in wet grinding plants. They can be used for green field plants as well as for plant upgrades.
The crusher plant supply
Our organisation is designed to handle system supply on a turnkey basis. We can draw upon professionals in offices all around the world to provide process engineering design & layout, contract management, inspection, shipping, expediting, purchasing, equipment erection, start up, training and customer service.
Simulation of grinding circuits
The capability to design entire grinding circuits with aid of state-ofthe- art simulation tools allows Polysius to design and build complete grinding lines to meet the high standards demanded by our clients in the minerals and cement industries.
The in-house expertise allows Polysius to provide application-specific solutions for economical, reliable and energy efficient grinding of ores, cement clinker, coal and other materials. Polysius has been successfully designing and building grinding plants since 1880.
The resulting global know how of process and plant technology, together with the extensive grinding test facilities in our research and development centre provide the basis for an optimum design. Grinding plants from Polysius have a long track record in wet grinding applications. They are operating in open or closed circuit mode. Polysius grinding mills can be of the overflow type or of grate discharge design.
In 1976 Polysius adopted the design of shell-supported grinding mills using slide shoe bearings. Since this time, the design has been perfected based on the experience of more than 180 units operating all over the world in various industries. Today Polysius grinding mills are exclusively built as shell-supported units.
The design offers such benefits as:
. Elimination of castings and the structural risk associated with them.
. Feed and discharge designed to process requirements rather than to restrictions imposed by trunnion bearings.
. Minimised risk of feed blockage through short trunnions.
. Quick accessibility to mill interior.
. Lighter weight and lower number of flanges for ease of transport and erection.
. Lower space requirement for less foundation and civil cost.
. Ideal for ring motor drives.
Polysius grinding mills can be driven via ring gear pinion drives or the COMBIFLEX® drive for drive capacities of up to 16,000 kW. Higher drive power is reliably transmitted via ring motor drives.
