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.

1. Screw conveyor design : methods How to size a screw feeder ? Screw conveyors are among the most widespread equipment for transporting and dosing bulk solids. It is thus required in many projects to calculate the size of a screw conveyor in order to reach a required capacity.

Inclined screw conveyors typically operate from slightly above the horizontal position to 45 degrees from the horizontal position. Above 45 degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the CEMA guidelines for vertical screw conveyors.

Roberts Emeritus Professor and Director, Centre for Bulk Solids and Particulate Technologies, The University of Newcastle, Australia. SUMMARY. This paper is concerned primarily with screw conveyors with fully enclosed tubular casings.

JHS800 Screw conveyor. Jansen & Heuning produces screw conveyors for many products like flour, grain, salt, fertilizer, protein, waste products etc. For special applications like sticky products, shaft-less blade screws are used. Available as a U-trough or pipe screw for horizontal, sloping or vertical transport.

The vertical screw conveyor/elevator is useful in the transport of semi-solids, bulk, and semi-fluid materials up and down a vertical shaft with the use of a screw-shaped shaft known as an auger. They take up a very small footprint and are best at regulating a uniform rate of materials. They are commonly used in wastewater facilities, chemical ...

Vertical screw conveyors are designed based on proven technology and allow for efficient elevation of bulk materials without any restriction to product flow. KWS …

Material is fed through the screw conveyor's inlet, passes through the conveyor via the turning auger, and is taken out via the discharge end. Screw conveyors can be configured in a horizontal, vertical, or inclined arrangement. The simplicity of the screw conveyor design allows it to be used in many different applications.

A vertical screw conveyors conveys material upward in a vertical path. It requires less space than some other types of elevating conveyors.Vertical screw conveyors are also referred as 'Lifts' or 'Elevators'. Vertical screw conveyor can handle most of the bulk materials provided there is no large lump.

Flexible screw conveyors can convey in any direction – from horizontal to vertical, routed around fixed obstacles and equipment, and from one room to another. Additionally, flexible conveyors are ideal for lifting materials from bag dump stations or storage bins.

A horizontal screw conveyor is the most distributed version of a screw conveyor because of its simple and easy-to-use design. These conveyors can transport materials at 15-45% through loading, which means that up to 45% more material may be transported than what could have been on other types of designs in the past due to how much easier it was made for operators.

Screw conveyors can be designed to be vapor-tight or hold an internal pressure. This is very important when conveying toxic or hazardous products such as those in the chemical industry. Screw conveyors can provide an air lock between upstream and downstream equipment. Photos 1.1 VERTICAL SCREW CONVEYOR

Screw conveyors are compact in design and easily adapt to congested locations for conveyance of materials in a horizontal, inclined, or vertical screw conveyor. Inclined screw conveyors are widely used, however they are not recommended for inclines over 25 degrees. Once the incline of the screw conveyor exceeds 25 degrees, issues with product "fall-back" and gravity require a …

Options include trough type screw conveyors, to fully enclosed tubular screws, shaftless screws, vertical screws, bio-mass screws and a variety of product specific screw conveyors such as the prolific WAM ES cement screw conveyor. The modular design of WAM equipment is such that screw conveyors are very competitive, and spare components are ...

Many years of experience in the design and practical application of screw conveyors has resulted in the refinement of conveyor design. This design procedure, outlined in the Engineering Section of this catalog, makes it possible to calculate size, speed and required power with a minimum of mathematical calculations.

Thus TSHP is calculated as follows: TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.
