High G-Force (up to 50 g’s)
Dry screening raw coal down to 3mm, drive speed is 800rpm
² Principle of Operation
The special feature of this screen is the dual vibration principle. With the aid of resonance, one drive provides two vibration movements that is a fundamental oscillation (rotating eccentric) and an overlaid vibration (floating deck). In this process, the screen panel continues expanding and contracting (over 800 times per minute) so achieve a high acceleration rates (up to 50 g) and prevent the screen panel openings from plugging.
There are over 300 Bivitec screens currently dry screening coal at coal mines and steel mills in China， India, South Africa, Korea & Western Europe at cut points down to 3mm. There are over 2000 Bivitec screens currently operating worldwide in mines, rock quarries, steel mills, cement plants etc.- screening sand, aggregates, iron ore, limestone etc.
Ø Bivitec polyurethane screen panels are a special design which have a long service life.
Ø The drive speed is 800rpm, the acceleration to the material can be up to 50g.
Ø Screen mats are fixed without screws guarantees a gentle screening as well as a fast change.
Ø Ox-horn design insures no wear of the side plates and no misplaced material in
Ø No need to clean the screen mats after shut down due to its good self-cleaning ability.
Ø The machine is seated on hollow springs made of rubber cause little noise and provide a high service life.
Ø Floating deck stroke is adjustable from 12 to 18mm.
Ø G-Force adjustable from 10-50 g’s .
Ø The cut point down to 3mm for coal or 0.2mm for other application.
Ø Less moving parts, high reliability, low maintenance, high availability.
² Machine Data
