How does the Solid Waste Pellet Machine Work?

Solid waste pellet machine, as the core equipment to realize the densfication treatment of bulk waste, converts the disordered waste into high-value ordered particles through precise mechanical compression technology. The system integrates multi-stage pre-pressing system, ring molding roller forming unit, thermal control module and hydraulic gap adjusting mechanism, which promotes the innovation of solid waste treatment technology with unique design concept and working principle.

The solid waste pellet machine shows great adaptability in the material preparation phase. The mixed wastes are firstly crushed and screened to form the particle size meeting the requirements, and the moisture content is strictly controlled within the plasticizing window through precise drying or spraying operation.  in this process, that fibrous material undergoes helical shear in the pre-compression cham, creating a fibrillating effect that exposes more binding site.

Compression molding is a core link of a solid waste granulator, in a dynamic extrusion space formed by a ring die and a compression roller, a tapered through hole of a rotary ring die is matched with a hydraulic compression roller to form a progressive compression area, so that materials entering a wedge-shaped channel sequentially complete particle rearrangement, elastic deformation and plastic flow, extrude, rub and thermally soften organic matters and activate a natural adhesive; During bonding and consolidation, organic substances are melted and cooled to form a bridge frame, inorganic particles are subjected to cold welding, water forms a liquid bridge, and the forming quality is guaranteed by multiple mechanisms; and the formed strip-shaped objects are cut to a fixed length, vitrification transformation is completed in air-cooled conveying to form a hardened shell, and finally, unformed broken materials are separated by a vibration screening device, so that closed circulation of materials is realized, and efficient utilization of resources is achieved.

How to deal with the composition fluctuation leading to the decrease of molding rate?

The difference in compressibility of that raw material is flexibly compensate by dynamically adjusting the gap between the die roll. Precise optimization of binder phase melt viscosity with closed-loop temperature control.  the load current of that main motor is monitor in real time, and the plasticizing state of the material is reversely calculate, so that the self-adaptive adjustment of the running parameters of the equipment is realized.
