u31ee_132816.jpgTube Belt Conveyors
These tube belt conveyors are engineered for stationary applications requiring the transfer of high volumes of bulk materials without exposure to the environment. The tube design provides the highest capacity for a given belt width allowing slower belt speeds to minimize product damage. Anti-static UHMW bed liners are utilized for abrasive products that would normally require roller bed conveyors and also to reduce coefficient of friction to minimize power requirements. Multiple standard conveyor designs are available, including flat and troughed, slider and roller bed frames for horizontal and incline applications, corrugated sidewall belts for steep incline applications, and flat wire and powered rollers. Chantland-MHS, Humboldt, IA 515-332-4045

u326c_132817.jpgFlexible Screw Conveyor
This flexible screw conveyor is easily installed for transporting dry, solid materials between two points either horizontally or at an incline. The unit consists of a fabricated inlet and outlet head of either mild steel or stainless steel. Between the inlets and outlets is a continuous length of UHMW polyethylene tubing, which clamps to the inlet and outlet via standard compression-type couplings. At the outlet head is a direct coupled helical gearbox and electric motor. Connected to the drive shaft is a flexible and shaft-less auger, which extends down and into the inlet head. The shaft-less auger is a continuous coil of either plain steel or stainless steel. Carolina Conveying Inc., Canton, NC 828-235-1005

u3264_132831.jpgScrew Conveyors for Dried Sludge
CEMA-type screw conveyors are made of 300 series stainless steel. The stainless steel protects the conveyor against the acid content of dried sludge granules, while the replaceable liner protects the trough from extensive wear and can be easily replaced when it is needed. A screw conveyor without intermediate hanger bearings is ideal for conveying sludge, however where it is not possible, the conveyors run with a 30% maximum trough fill to avoid a strong impact on these bearings. WAM Inc., Fort Worth, TX 817-232-2678

u327e_132827.jpgPipe Conveyors
To receive material, the belt is open like a conventional belt conveyor in the feeding area of the pipe conveyor. After a certain distance, which depends on the pipe diameter or belt width, special belt forming rollers mould the belt into the desired closed shape. The rollers smoothly roll in the belt, avoiding friction between the belt surfaces. From this point on, the closed belt runs along the entire conveying distance, through what are known as panels and partition plates. Six rollers are installed in a staggered arrangement on each of these panels for the upper and lower strands. The tubular shape of the belt makes it possible to maneuver horizontal and vertical curves without additional transfer stations. At the end of the conveying line, the belt opens on its own and discharges the material like a conventional troughed belt conveyor. Beumer Corp., Bridewater, NJ 732-560-1155

u3276_132826.jpgCentrifugal Discharge Elevator Bucket
The Tiger-Tuff industrial-duty elevator bucket is a direct replacement for any AA style elevator bucket, and adds longer life and more capacity. The bucket is built with a thicker front lip, corners, and walls to increase elevator bucket life and maintain maximum capacity. The Tiger-Tuff averages approximately 30% more capacity than same-sized AA style elevator buckets. It is available in nylon, urethane, and polyethylene materials. Nylon is the most commonly used material for industrial applications, possessing excellent abrasion and impact resistance. It easily operates in temperatures up to 300ºF.
