Bucket Elevators

PPM bucket elevators lift a wide range of dry, free-flowing products such as nuts, snacks, cereals, pet food and confectionery. They are built either with an open tubular frame or with sanitary solid wall plates, in stainless steel or carbon (mild) steel. Units are assembled from modular sections, which makes initial installation simple and allows later changes such as horizontal and vertical extensions.

Buckets and chain

Heavy-duty one-piece buckets, up to 48″ wide, in polypropylene or polycarbonate, have overlapping (not interlocking) flanges at the fill point to prevent spillage between buckets. At discharge the buckets turn completely over and stay face-down until they return to the fill position, so they can be cleaned while moving. Heavy-duty extended-pitch roller chains with large rollers run on tracks instead of sliding, which reduces friction, wear and power demand; they are available in mild or stainless steel, and Delrin rollers with pre-lubricated, impregnated bushings can be supplied where lubrication is not possible.

Sanitation and cleaning

• Stainless or carbon steel construction
• Open tubular frame or solid wall
• Complete bucket turnover at discharge, returning upright at the fill position
• Optional washing system for automatic bucket cleaning between shifts
