Claims18
A trommel comprising:
- a frame comprising a pair of substantially circular spaced apart end rings and a plurality of longitudinally extending ribs, each rib extending between and attached to said end rings, each said rib defining a channel that faces outwardly;
- and
- a plurality of screen panels including a screening portion and an attachment portion, said screening portion having a plurality of sizing holes, said attachment portion including a radial arm extending inwardly from said screening portion and a lateral arm extending away from said screening portion and away from said radial arm at substantially a right angle thereto, wherein said radial arms and said lateral arms of adjacent screen panels are received within said channel and fastened therein.
A trommel comprising:
- a frame comprising a pair of substantially circular spaced apart end rings and a plurality of longitudinally extending ribs, each rib extending between and attached to said end rings, each said rib defining a channel that faces outwardly, said channel being comprising a base web and a pair of side webs, said side webs extending outwardly from said base web;
- a plurality of screen panels including a screening portion and an attachment portion, said screening portion having a plurality of sizing holes, said attachment portion including a radial arm extending inwardly from said screening portion and a lateral arm extending from said radial arm portion at substantially a right angle thereto, wherein said radial arms and said lateral arms of adjacent screen panels are received within said channel and fastened therein;
- and
- a plurality of clamp bars, wherein two adjacent screen panels are tastened to one of said ribs by a said clamp bar, said clamp bar being received within said channel between said radial arms of said adjacent screen panels such that said clamp bar clamps said lateral arms of said adjacent screen panels between said clamp bar and said base web of said rib.
