The raw material is loaded into the container via self vent vacuum sys(in case this option selected),or other loading sys as requested;and mechanically fluidized inside the container under the impeller force,which realizes the perfect mixing performance.Loading the binder into the container and starts the chopper;The material coheres together by the binder which forms the binder bridge for form the core granules.Under the mechanical energy conversion.the qualified granule grows up and formed.
