Screw feeders or spiral feeders. Screw feeders or spiral feeders can be either continuous feeders or batching units. Continuous feeding is characterised by releasing a constant amount of product over a set time. Over a set time, the batching unit must release a set quantity of product over a series of programmable cycles.
Klinkenberg screw feeders do what they are designed to do, under all circumstances and with every imaginable product. The screw feeders are available in completely gas-tight versions for dosing very fine or hazardous powders and granulates. This means that hazardous vapours and noxious odours remain inside the system!
For this reason, PTN has developed its own feed systems ( feeder screw ). The details make the difference in this feeder screw manufactured entirely from stainless steel. The geometry of the shaft flight guarantees a uniform product flow. For use as dosing and conveyor screw for meal and granulates. Features Feeder Screw
With dosing screws, an exact volumetric dosage of bulk goods can be undertaken. This is achieved by a specific spiral geometry which is adapted to the product. The product flows from a funnel or silo into the screw conveyor and is transported carefully by it to the outlet. A frequency-controlled drive motor regulates the output.
1. What is a screw feeder. Screw conveyors are a very popular equipment in solids processing industry to move and / or dose products. Their principle allows a simple and quite robust operation, although the design must be well detailed in order to avoid issues that could lead to damages to the product and to the equipment itself (generation of foreign bodies).
By its nature, Gain-In-Weight dosing is a batch operation and therefore cannot be applied for continuous dosing. Wherever continuous dosing is required (feed of a mixer for example), it will have to be done by Loss-In-Weight feeders.
Fed via a bag opening hopper, a bulk bag discharger, or another feeding device, the SINT engineering polymer FLEXFLO body, with its particular geometry, ensures constant material flow and dosing through the feeder screw. To further facilitate material flow an …

A feeder is essential for controlling the flow rate of bulk solids from silos, bins, and hoppers. The feeder is an integral part of a storage system because it can have a major impact on the flow pattern in the storage vessel – it can either maintain reliable material flow or induce poor flow, segregation, or flooding of fine powders. Proper selection of a screw, belt, rotary valve (rotary ...

Application Installation for feeding & conveying activated coal for exhaust gas cleaning The system features a main screw conveyor which feeds 3 dosing/conveying units that consists of an gravimetric feeder (metering capacity: 3x10 kg/hour), a pneumatic conveying system with blower and venturi eductor (conveying distance approx. 40 metres) and a redudant blower unit (for emergencies).
Volumetric screw dosing machine mod. MF-DCV 5000 suitable for dosing particularly fluidified powder products. The rolling action of the dosing machine feeder screw on the product, allows the excess air to be eliminated, thus allowing it to be compacted in the bag during the discharge phase.
For dosing feed rate - a mathmatical formula is used to select the right pump flow rate for your chemical concentration and application. The required information for sizing a chemical feed pump includes: Chemical solution concentration in PPM (parts per million) Water pump (or feed flow rate) output in GPM (gallons per minutes

These materials are often best handled by a twin screw feeder with hopper agitation, such as Coperion K-Tron's ActiFlow TM. Fragile and friable materials, such as many food products and fibers must be handled carefully. Weigh belt feeders, vibratory feeders and loss-in-weight belt feeders are designed for gentle feeding of these products.
A typical volumetric feed system includes a bulk storage bin or silo, a feed hopper, and a metering device. The most common metering device is a helical screw or auger. The rotational speed of the screw determines the feed rate. Some powders tend to bridge, or "rathole," causing uneven feed.
