Dryer-Pulverizer

Application

In one step, for humid products down to a final corn size of 90µ.

Most usual products :

• Minerals (coal, lime stone, gypsum, kaolin, pigment, talc-clay, ...)
• Mud,
  
• Filtercakes,
  
• Agglomerate powders, ...

Working principle

1. Pulverizing

• First pre-grinding section, with swing hammers, for a feed corn size upto 50 mm,
  
• Second grinding chamber, between fix and module pegs,
  
• Internal classification (larger residence time) to adjust the final corn size.

2. Drying

• Hot air (max 600°C) is introduced in the feeding chute and succed through the mill body, by an exhaust fan. A bag filter collects the fines. Evaporation capacity up to 4 TPH water (Serie A) or 6 TPH water (serie B).

Construction

• Fabricated body, internally machined with a large hinged access door,
  
• The main rotor consists of a steel disc, where swing hammers and mobile pegs are mounted on.
  
• Each part can be easy handled.

Option

• Serie A: carbon steel
  
• Serie B (light) stainless steel - No pre-grinding chamber
  
• Internal exhaust fan

Test

Each product may be tested in a semi-industrial scale unit, to issue a performance guarantee and the wear resistance.
