Screw conveyors are the most suitable conveying equipment for conveying free-flowing material between two points over a short distance, either horizontally or slightly inclined, where no change in direction is necessary. The conveying operation is carried out by the thrust of the screw. The Screw Conveyor consists of a shaft and mounted screw rotating in a U-shaped trough between the end bearings. To prevent any accumulation of material, an emergency outlet called overflow flap is provided at the end of the conveyor. A limit switch is also provided mounted on it so as to avoid tripping of the motor.
The Bucket Elevator is used for conveying the material from lower level to higher level in the plant. The material entering at the bottom inlet is carried to the top by the bucket and discharged centrifugally in the outlet of the elevator. It consists of a rubber belt fitted with buckets at required intervals vertically and top and bottom pulley inside a fabricated steel casing (troughs). The top pulley is rubberized to provide drive without any slip. Pawl-and-ratchet type back stop is provided on the top pulley to prevent reverse rotation due to the weight of the material on the active side of the belt.
The Chain Conveyor is used to convey different dry free-flowing materials from point to point using the least power and the smallest size of conveyor chain. The chain speed ranges from 0.5 Meter per second to 1 Meter per second.
The Rotary Valve is a device which performs a vital function in the feed milling and food processing industries that is to discharge powdered materials from the cyclones of pneumatic systems without allowing air to leak past the openings. In a pressure system, it permits material to be injected in the conveying system at the feed point where there is consequently a tendency for the air to leak to the atmosphere. Besides loss of pressure, this results in considerable dust nuisance and necessitates a larger air pump and a higher power consumption than would otherwise be required. In order to overcome this problem, a rotary valve is used as an air lock. It either feeds materials into the conveying system or discharges materials from it without allowing the conveying air to lock nut.
Vibratory Bin Discharger is ideal for the uniform discharge of non-free-flowing materials such as high-oil-content flours, baby foods, high-protein blends, etc., from storage bins or silos. Special flexible rubber connections isolate vibrations completely from the main discharge bin while permitting unrestricted movement of the discharger cone. The Vibratory Bin Discharger is available in capacities ranging from 1 TPH to 15 TPH, in either Mild Steel or Stainless Steel construction, depending upon the application
