Purpose of the machine:
the sorter is designed to homogenise the maximum size contained in the flow of the inlet process material.
The machine brings to the desired size that remaining fraction of larger-sized particles, maximum 5-10% of the total, contained in the flow of the material, in order to avoid clogging the dosing devices of the downstream process system.
Sorter Description:
the sorter essentially consists of:
– two counter-rotating rotors, each individually controlled by its own drive train consisting of electri motor, gearbox and hydraulic coupling
– two grids (crushing plates), one for each rotor, manually adjustable to limit the maximum through size
The rotors are composed of:
– a series of cutting segments, made of steel with high resistance to wear and stresses, which can be replaced without having to remove the transmission shafts
– a contaiment and support structure for the mechanical elements, equipped, in the areas affected by the flow and contact of the material, with anti-wear steel guards
– two transmission shafts, one for each rotor, equipped with supports and bearings at each end
– automatic overload protection systems
– a carrier wheel system for fast transfer from the working position to the maintenance position
– gearbox oil cooling control unit
Field of use:
For materials with a grinding index according to Bond up to about Wi=7 or up to a compressive strenght of material of about 300 MPa
Advantages of the App Size Sorter:
– crushing rotor shafts supported independently from gearboxes
– crushing segments that can be replaced without having to remove the relative shafts
– supports with metal and grease seals
– low speed crushing so in without vibrations, noise and dust emissions
– insensitive due to the fouling of wet material because self-cleaning
– possible operation even of a single rotor to ensure system operation
