Modern screw conveyors

Screw-conveyor feeders are universal machines commonly used in the agricultural industry as well as in grain storage, construction, and many other economic sectors. Their main purpose is to transport seeds, fodder, cement, alternative fuels, pea coal, fine coal, and any other type of loose material (but not only) over short distances. Commonly, they are used as crucial elements of production lines and technological chains. Devices differ from each other by the working length, capacity, work angle, travel, outer diameter, drives type, etc. FMK Sp. z o.o. owns a modern machinery park that is used to produce screw conveyors with parameters adjusted to particular applications. In order to satisfy customers’ requirements, we opened a material transport laboratory, so that we are able to test prototypes of screw conveyors in order to optimize them in terms of energy consumption or to determine the required working characteristics.

Cold forming

We own a CNC machine that allows forming blades through cold forming. As a result, we are able to provide a screw conveyor with blades that offer a wide range of parameters. We create elements that feature unique precision and repeatability. Devices meet the rigorous standards included in the currently applicable European directives, which is confirmed by the attached certificates. We provide screw conveyors made of stainless steel, heatresisting steel, or even acid resistant steel. Transport with a screw is performed horizontally, at a specific angle, or vertically. The modular construction of those devices facilitates adjusting them to specific functions, i.a.: feeding, selecting, and dosing. We use powder coating to paint industrial perpetual screws with a selected RAL color.

Types of screw-conveyor feeders

With regard to structure and type of application, we can distinguish several basic types of industrial perpetual screws:

With regard to structure and type of application, we can distinguish several basic types of industrial perpetual screws. Tray screw conveyors are equipped with a special enclosure the shape of which resembles letter U or V. Removable lids allow easy access to the perpetual screw, so this type of feeders is used at any place that involves the risk of transporting elements getting wedged or stuck. Devices are produced in several load versions: light, medium, and heavy. Upon request, they can be adjusted to the ATEX standard.

Pipe screw conveyors have an enclosure in the shape of a pipe inside of which the perpetual screw operates. They are tight and made of wear resistant materials, which guarantees long service life. The high-quality construction reduces vibrations and, as a result, tiresome noise. This type of screw conveyors is very often used in the mining industry, at cement plants, for production of limestone and gypsum, and in foundry. We offer a rich selection of inlet and outlet holes as well as methods for shaft sealing.

Our offer also includes the Archimedean screw turbine. It consists of a closed or open pipe with screw-shaped rotor bar inside it. It uses the kinetic energy of a water stream or river. What is important, this solution is environmentally friendly (fish and other small aquatic life can be safely transported in the water), so it can be applied in all places that require compliance with strict environmental standards. It also features low operating costs and high reliability.

High-quality devices for material transport

Transport with a screw dispenser takes place at a minimum level of power consumption. It also features high efficiency at low rpm. The lack of screws and nuts inside the dispensers greatly decreases requirements for maintenance. Eventual repairs can be performed within a short period, which helps avoid cost-intensive downtimes at the plant. Among others, this is the reason why screw transport has currently been one of the most popular solutions in many industrial fields.

What is more, spiral conveyors have been designed in a way that allows transport of various types of non-homogeneous materials, such as screenings, food processing waste, or paste. Screw conveyors also feature a high level of self-cleaning.

Each ordered screw conveyor can be produced in many options, with the use of accessories that expand its functionality. We apply various types of liners and drive transmission methods. As a result, we can offer an advanced transport with screw conveyors, compliant with individual expectations, to a wide group of customers.
