A garbage recycling machine must be able to handle huge amounts of waste, separating, shredding and compacting, so it is ready for repurposing. Most reclamation facilities are sprawling centers of high activity. Housed in these centers, hundreds of feet of conveyors crisscross and carry different forms of waste to different processing areas. Before they are ready to be processed, though, the waste must be separated into paper, glass, plastic and metal. This is done using clever applications of magnetism, gravity, air pressure and mechanical force.
At the processing center, huge trucks unload tons of recyclable material every hour. This material is loaded onto conveyors which carry it to different separation devices. Every garbage recycling machine complex needs several separation methods to ensure that everything is sorted out thoroughly. Without precise separation, the repurposed material will contain impurities that affect its usefulness. Fortunately, modern facilities have access to reliable separation methods. Metal and glass are separated from paper and light plastic first using blasts of pressurized air. These controlled blasts suspend the paper and light plastic, while metal and glass proceed unhindered to another part of the facility. The metal is removed from the glass later down the line using a series of powerful electromagnets. Eddy currents may also be installed along the conveyors, and these are effective at removing nonferrous metals from glass or ferrous metals.
Lighter plastic is removed from the paper using mechanical force. The aggregate material is channeled over an oscillating panel which bounces the plastic onto another conveyor. The paper is unaffected by this oscillation and continues elsewhere. Once everything is sorted using these methods, a garbage recycling machine like a shredder can size reduce the material for further processing. Industrial shredders like those produced by UNTHA are capable of handling tons of material every hour. Huge single, dual or quad shaft shredders can chew through everything, from loads of paper to huge chunks of wood to full size appliances. Reducing everything to a uniform, smaller size is an important part of the reclamation process. Without shredding, it would impossible to precisely separate material or to ready the waste for easy baling, transport and reprocessing.
Once reduced in size, a garbage recycling machine like a compactor presses the paper, plastic, metal and glass into huge bales for easy storage and transport. These bales are several tons heavy each and are sold to processing plants for pennies on the dollar. At these plants, the material is melted down (if metal, plastic or glass) or chemically treated (if paper) and restored to usable material. At metal reclamation centers, heavy duty magnets are typically used to move around huge loads of ferrous metals.
Other forms of reclamation, like rubber and wood, require a garbage recycling shredding machine. Rubber and wood are more difficult to repurpose because they can’t usually be returned to their original state. However, they are both highly useful as alternative fuel sources, bulk structural material or lining material for playgrounds, sports arenas or other structures. However, before rubber and wood can be used again, it must be shredded down to a small uniform size, something that can only be done with a powerful shredder like those manufactured by UNTHA.
