MacGregor screw conveyors MacGregor horizontal and vertical screw conveyors operate with the helical screw flight driving and throwing bulk material forward by rotational force with capacities of up to 1,500 m³/h. Their rigid, heavy-duty construction reduces wear and enables easy maintenance, which is only required at infrequent intervals.

Screw Conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. It is important to understand, however, that as the angle of inclination increases, the allowable capacity of a given unit rapidly decreases. A standard Screw Conveyor inclined 15° upward ...

Screw Conveyors Hazards: Screw conveyors are troughs with a revolving shaft with a spiral or twisted plate. In‐going nip points for the entire length of the screw conveyor exist between the revolving shaft and trough. Because the trough may not be covered and the conveyor may be located at or
5 CONVEYOR PULLEY SELECTION GUIDE Pulley/Core Diameter – The outside diameter of the cylindrical body of a conveyor pulley, without coating. Finish Diameter – The outside diameter of a coated pulley (core diameter + 2 times the coating/wrap thickness). Face Width – The length of a pulley's cylindrical body.This area is intended to act as the contact surface for the conveyor belt.
shaft and screw assembly known as screw conveyor receives power via the reduction gear box and runs in a journal bearing. The screw on the conveyor is 77 mm apart on the shaft and tapered from 12.5 mm at the feed entry point to 10.5 mm at the discharge end. The screw conveyor and housing provide the shear and compressive forces needed to crush the

Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors. As the degree of incline increases, conveying efficiency is reduced and horsepower requirements increase due to the effects of gravity and bulk material fall back.
Design SCREW CONVEYOR DESIGN PROCEDURE Establish Known Factors 1. Type of material to be conveyed. 2. Maximum size of hard lumps. 3. Percentage of hard lumps by volume. 4. Capacity required, in cu.ft./hr. 5. Capacity required, in lbs./hr. 6. Distance material to be conveyed. 7. Any additional factors that may affect conveyor or operations.
