Volume reduction of bulky materials and items is all done using the shredder machine. shredding machines can be of many forms depending on the material being shredded. When designing a shredding machine, several factors are taken into consideration, including the material to be shredded, the volume of material to be shredded, the area in which the shredder will operate (on a farm, in an office, outdoors, indoors, etc.), the available space set apart for the machine, the frequency at which the shredding machine will be utilized, and client budget. Shredding machines consist of feed shafts (for industrial applications), a feed zone into which materials are placed, crushing gears or slicing blades, a motor to spin the blades, and a chute (also for industrial) which transports the materials onto a conveyor for more handling or into a container for disposal.
