FIELDS OF APPLICATION

hammer mill coal

hammer mill

Hammer Mills are utilized for primary as well as secondary crushing of numerous types of material in just about all industrial sectors.

FEED MATERIALS

Difficult coal and lignite within coal processing vegetation, coking coal for that iron and metal industry, limestone as well as gypsum rock or even other related gentle to medium-hard mineral deposits, as well as various kinds of salt.

MODE ASSOCIATED WITH OPERATION

The feed materials is distributed within the whole width and fed towards the machine by various kinds of conveyor techniques. The high rotational speed from the beater heads creates a closed signal. The feed materials strikes the beater mind from above and it is hurled between the beaters and also the impact wall while passing with the machine. This repeating process helps to ensure that the feed materials is crushed towards the desired product dimension.

The flexible suspension from the beater arms about the rotor ensures how the Hammer Mill is actually insensitive to damages brought on by any hard foreign particles which may be in the give food to material. The beater mind are wear parts and may easily be changed. Adjustment of the actual grinding wall towards the crushing radius (gap width) as well as rotor speed (m/s) tend to be major factors within determining the decrease ratio and item size.

SPECIAL FEATURES

The rotor is forged in a single pieoe, the fixing holes for that beater arms are arranged inside a special device. The precisely balanced design from the opposing beater hands and beater mind ensures smooth operating. The beater arms are constructed with high-quality steel and therefore are easy to substitute. The beater heads are produced from alloy steel or even compound casting.

Hammer Mills are made to be driven from either constant or even variable rotor rates of speed. Inspection flaps and also the hinged housing make sure easy maintenance.

DESIGN

The non-reversible Sludge hammer Mill (type 1211) enables the beater heads to become reversed when 1 side is worn-out.

The reversible Sludge hammer Mill (type 1212) enables bi-directional operation to ensure that both sides from the beater heads may be used.

VERSATILITY

Depending about the application, various configuration choices and/or additional structural elements may be used:

  • reversible as well as non-reversible: Hammer Mill The actual reversible version enables the beater heads to become utilized to their own optimum by curing the direction of drive and never have to reverse the mind themselves. A quantity of different drive concepts can be found. The Hammer Mill could be driven at possibly constant or adjustable speed.
  • mechanically flexible impact walls: For compensating put on and achieving the required product size.
  • hydraulically flexible impact walls: For tasks which frequently vary with regards to product quality as well as particle size submission.
  • pressure surprise resistant design associated with housing: As the protective device whenever processing hazardous give food to materials.
  • with encircling impact wall: For very damp feed materials having a tendency to block.
  • with warmed impact walls (electric, vapor or heat move oil): To improve materials flow when processing materials having a tendency to block.
  • with replaceable grate: In order to limit oversized feed. Not suitable with regard to moist, sticky as well as clayey feed supplies.
  • for mixed grinding and drying out: To reduce dampness content while mashing the material simultaneously in one period.

ADVANTAGES

  • high and constant capacity
  • high availability
  • long lifetime
  • easy replacement of wear and spare parts
  • broad range of application
  • high reduction ratio

SCOPE OF APPLICATION

  • feed size: up to approx. 300 mm
  • product size: up to < 1 mm depending on type and size of feed material
  • capacity: up to 5000 t/h
  • reduction ratio: up to 1:30
  • required power: up to 1800 kW
