Abstract
1331927 Hoppers USI ENG Ltd 22 Feb 1972 8200/72 Heading B8S [Also in Divisions B2 and F2] A comminuting apparatus comprising a base 4, Fig. 1, cutting means 6, a motor 12, an inlet 8 and exit 10, has a combined sound-absorbing hopper 60 Fig. 4 and enclosure 26. The hopper and enclosure comprises an elongate tubular structure with outside and inside composite walls which are spaced apart to provide an air space between them. The outer walls form the enclosure 26 and the inner walls the hopper 60. Means 80 space the walls apart. The outer wall comprises an outermost sound attenuating layer 46, e.g. of aluminium brass or copper, and inner layers 48, 50 and 52 of foamed plastics lead and foamed plastics respectively suitably adhered by e.g. epoxy resin. The hopper 60 comprises side, back, bottom, top and front walls 70, 72, 74, 76, 77, 78 reinforced with plates 82 and covered with a sound damping material 61 of, e.g. clay-epoxy resin mixture or vermiculite. The structure is hinged at 28 Fig. 1, to the base 4 to permit access to the inlet of the comminuting apparatus. The inlet is soundinsulated by curtains 86 comprising pairs of flexible elastomeric sheets, 88, 90. The drive shaft is insulated by a pad 106, Fig. 3 and the pulley drive 18 and belts 22 by a shroud, 96. A discharge bin 110 is removably secured by a bracket 114 and dog 116 to the underside of a slanting upper table 32 of the base of the machine.
