CPC Hammer Mills

CPC Hammer Mills

Application

• Hammer mills are used for crushing medium-hard and soft materials (coal, limestone, gypsum, clay, marl, salts, phosphates, etc.).
• The processing of feed material with increased moisture is also possible in CPC hammer mills.
• Grinding drying by feeding hot process gas (e.g. flue gas from a combustion) into the hammer mill

Mode of operation

• To break coarse grain, the feed material is caught by the impact hammers and thrown against the upper area of the grinding wall (impact wall).
• In the middle area of the grinding wall, the material to be ground is ground and shaped
• In the lower area, the material to be ground can be classified by using a grinding grate (usually bar grate depending on the application, optional)

Features

• Modular hammer design consisting of hammer handle and hammer head (separate replacement of hammer heads)
• Long service life due to bimetal hammer heads made of an extremely hard chrome alloy on a tough hard carrier material
• The rigidity of the rotor is achieved by high preload (several 100 to) during production, thus no deflection even at widths of up to 3 meters.
• The rotor is dynamically balanced according to DIN 1940 quality G6.3
• Drive by means of V-belt or direct drive
• Reversible direction of rotation, thus extending maintenance intervals, longer travel times and reduced spare parts costs due to use of the hammer heads on both sides
• The grinding gap can be adjusted from the outside.
• Very good accessibility due to hydraulically foldable grinding walls for inspection and maintenance.
• The adherence of moist adhesive material on the grinding walls can be prevented by heating with electrically heated thermal oil (option)
• A local operating station with control and monitoring function (PLC) is standard equipment.
• The bearings are lubricated by a central lubrication station.
• The hammer mill can be mounted on a base plate with vibration dampers (option)
• Optional sound enclosure for sound pressure level <80 dB(A), maintenance-friendly design with quick-release fasteners.
