The screw conveyor is a mechanism that uses a rotating helical screw blade, usually within a tube, to move liquid or granular materials. Screw conveyors are used in many bulk-handling industries. In modern industry, screw conveyors are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates , and many other materials. Screw Conveyor ApplicationsThe screw conveyor is one of the most economical conveyor types available for moving bulk materials. It is completely enclosed to contain the moving material and its atmosphere. The standard unit, with variations in design, is suitable for solving a variety of bulk material handling problems. ![]() Screw Conveyors How to Properly Operate a Screw Conveyor1.Screw conveyors shall never be operated unless the conveyor housing completely encloses the conveyor moving elements. All necessary housings, covers, safety guards, railings, gratings and power transmission guards must be in place. If the conveyor is to be opened for inspection clenning or observation, the motor driving the conveyor is to be locked out electrically in such a manner that it cannot be started by anyone, however remote from the area unless the conveyor housing has been closed and all guards are in place. The housings, covers, and guards are necessary to prevent anyone from entering, reaching, or falling into the machinery, which may result in many serious personal injury. 2.If the conveyor must have an open housing as a condition of its use, the entire open conveyor is then to be guarded by a railing, fence or rugged safety grating. 3.Feed opening for shovel, front end loader or other mechanical equipment shall be constructed in such a way that the conveyor is covered by a rugged grating. If the property of the material is such that a grating cannot be used, then the exposed section of conveyor is to be guarded by a railing and there shall be warning signs posted. 4.Do not place hands or feet in any conveyor opening, to avoid being caught between the rotating conveyor screw and the conveyor housing. 5.Do not walk on conveyor covers or gratings or power transmission guards, to avoid falling into or against the rotating conveyor screw. 6.Do not poke or prod material in the conveyor with a bar or stick, to avoid being struck by the bar or stick. 7.Do not overload conveyor or use it for anything but its intended use.
