Terminology3.1 GeneralCommercial pulpers with waterpresses areintended for grinding food waste, food service paper andcardboard products, food service plas
17、tic 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 which is then passed tothe waterpress to be de-watered. Pulpers are not intended to beused for grinding glass, chin
18、a, 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 removable from a trap in thepulper tank.3.2 Definitions of Terms Specific to This Standard:3.2.1 pulperthe pulper ta
19、nk 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 may consist of the followingprinciple parts: tank, motor, grinding disk, particle sizing ring,trash box, legs, fe
20、ed 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 screen, then discharges the pulp down achute to a waste container. Water removed during this processis pumped to the
21、 pulper tank in order to conserve fresh wateruse. Waterpresses may consist of the following parts: shell,helical transport screw, perforated screen, gearbox, motor,compression cone, discharge housing, chute, and pump.4.
