17、ith waterpresses areintended for grinding food waste, food service paper andcardboard products, food service plastic products, documentsincluding computer printouts, general office and retail storepaper, and cardboard waste. Materials are ground in a water-filled tank (pulper) to produce a slurry wh

18、ich is then passed tothe waterpress to be de-watered. Pulpers are not intended to beused for grinding glass, china, metal, wood, clam, or oystershells. Any small pieces of metal inadvertently placed in thepulper, such as cardboard box staples, aluminum refreshmentcans, or tin food cans, shall be rem

19、ovable from a trap in thepulper tank.3.2 Definitions of Terms Specific to This Standard:3.2.1 pulperthe pulper tank has a motor driven grindingdisk to grind and cut waste material, and mixes this materialwith water to produce a slurry that is pumped to the waterpressthrough a sizing screen. Pulpers

20、may consist of the followingprinciple parts: tank, motor, grinding disk, particle sizing ring,trash box, legs, feed chute, stationary, and rotating cutters.3.3 waterpressthe waterpress de-waters the slurry gener-ated in the pulper by use of a vertical, inclined, or horizontalscrew and perforated scr

21、een, then discharges the pulp down achute to a waste container. Water removed during this processis pumped to the pulper tank in order to conserve fresh wateruse.
