WAM Minimum Residue Tubular Screw Feeders allow quick and efficient cleaning of all conveyor parts, as well as minimum material residue inside. To great extent, this is due to minimum clearance between the screw …

Screw feeders are well suited for use with bins having elongated outlets. These feeders have an advantage over belts in that there is no return element to spill solids. Since a screw is totally enclosed, it is excellent for use with fine, dusty materials. In addition, its fewer moving parts mean that it requires less maintenance than a belt ...

A screw conveyor with tubular housing and reduced pitch screw (1/2 or 2/3) and larger diameter is recommended for most applications. Increasing the speed of the screw …

Tubular Trough. Tubular troughs can accommodate larger screw diameters and contain and protect bulk materials from weathering, dust, and contaminants. They operate at higher speeds with a higher capacity per revolution and conveying jumps of 1% to 2% based on minute to minute weighed samples. Tubular troughs can be used with inclined screw ...

Advantages of Using Vertical Screw Conveyors. Ideal for handling dry to semi-fluid materials from free-flowing to slighlty sluggish. Capacities available up to 6,000 cubic feet per hour. Ability to elevate bulk materials up to 30-feet without use of internal bearings. Totally enclosed design for dust and vapor-tight requirements.

The tubular screw is intended to maintain continuous operation of the process. The easyclean version ensures fast and effective cleaning, while the flexible version can easily avoid obstacles in a restricted …

Mass Flow Screw Feeders for Rare Earth Elements. KWS utilizes mass flow or cone screw design as the most efficient way of metering the REE from hoppers. ... Placement of Hanger Pockets on Tubular Trough Screw Conveyor. When adding hanger pockets to a tubular trough screw conveyor, ensure the hanger pockets do not interfere with trough flanges. ...

The tubular screw feeders are supplied with split housing for ease of maintenance and easy inspections. Horizontal and vertical screw conveyors available for specific applications. Typical dimensions of the screw conveyors vary from 6" (150NB) to 20" (300NB) flight diameter. Standard lengths do not exceed 6 meters.

Description EASYCLEAN are specialised Screw Conveyors and Feeders entirely manufactured from stainless steel.
