Drums

Pronar MPB Trommel drums may be easily changed to suit material screening requirements. Pronar also produces screen drums compatible with other manufacturers’ machines.

Depending on the screened material: soil, compost, municipal waste, aggregate, biomass; different types of perforation are available, shapes include round or square, any size hole available.

There are 4 standard drum versions available:
• length 4,4 m & diameter 1,4 m
• length 4,7 m & diameter 1,8 m
• length 5,5 m & diameter 2 m
• length 7,2 m & diameter 2 m

There are 3 standard wall thickness versions: 6 mm, 8 mm and 10 mm.

Hole size, regardless of its shape, could be from 10 to 100 mm.

Star screen

Starscreen can be used instead of trommel. Utilising starscreen during works on wet material increases machine efficiency. The rotation speed of the stars can be steplessly regulated which allows for accurate setting of the separated fraction.

Destinated for:
• Municipal and industrial waste, compost,
• Shredder tree stumps, wood, bark,
• Contaminated aggregates: sand, gravel, clay, stones, soil, peat, coal,
• Materials for road or garden works

 

Available are starscreens for PRONAR MPB 20.55
