Dust removal and transport In conjunction with its dust-extraction systems, Deichmann Filtertechnik has also developed matching dust-conveying systems to enable effective and profitable removal and exploitation of dust as a raw material. Conveyor screws installed in pipes and troughs are among the primary systems used to remove dust from the extraction units. Conveyor screws by Deichmann can be effectively used in horizontal or slanting configuration to remove bulk material from industrial processes, and to ensure continuous conveying. All these conveyor screws are coordinated to the requirements of the material being transported. Transport distances beginning at 6m are already considered standard. Long transportd istances can be spanned by customized system designs. • Dust conveyor screws • Cellular wheel sluice • Double fiap valves with gravity or motor operation

ILCHMANN screw conveyors are engineered for a wide range of applications and are available with constant pitch for standard conveying duties, with progressive pitch for controlled discharge applications (e.g. silo extraction), or as plug screw conveyors for extractor/toaster feeding, or force feeding duties such as press feeding. Screw conveyors are suitable for horizontal or inclined conveying. For operation in potentially explosive atmospheres, gas-tight versions in accordance with ATEX requirements are available.

Our screw conveyors are highly versatile, compact in design and individually tailored to material properties, conveying capacities and the structural installation conditions. They are suitable for fine to coarse bulk materials and enable controlled, continuous material transport – even in confined spaces.

Screw conveyors are implemented for extracting and conveying nearly all bulk materials including fibrous and past-like products. They transport bulk goods by a rotating helical screw blade in a trough or tube. The advantages of screw conveyors are their low fault liability and economy, their reduced place requirement as well their dust-free conveyance. They also offer the possibility to feed and withdraw transport material along the haul road. SCHRAGE screw conveyors can be implemented in all industry sectors. The SCHRAGE range covers various types of screw conveyors such as trough and tube screw conveyors, twin screw conveyors and tempering, cooling and heating screw conveying units as well as mixing screw conveyors and bunker extraction screws. All facilities are dustproof and product sealed. Waterproof and gastight as well as pressure surge protected models are also possible. SCHRAGE Plant Engineering produces high quality screw conveyors, facilities up to 12 m length are deliverable also without centre bearing (depending on scale and design). As a norm the screw conveyors run by an attachable gear motor or spur gear system with coupling, special designs on demand.

Rigid - but still flexible! … It is under this heading that tried and trusted Wutra screws are supplied for use, even in most difficult conditions. - Robust construction to withstand the heaviest loads over long periods of time - Flexible system integration using 3D planning - Short delivery periods due to standardised modular constructions, as far as possible - Conveyor lengths up to 60 m - Conveyor capacity up to 800 m³/h A screw conveyor may be used for several associated process steps joined together to form one system. - Dosing - Mixing - Separating and sieving - Stuffing - Discharging - Washing - Cooling and heating

Tubular-, Trough-, Shaftless- and Vertical Screw Conveyors

The new srew packer BSP 25 is a compact machine for filling valve bags (optional also open bags) with powdry, heavy-flowing or fine ground bulk materials. The machine consists of a stable basic frame, a gross weigher with srew dosing unit, integrated agiator and a dust extraction system. The machine can be adjusted to different bag sizes. Benefits: - compact design - low height - transportable design - suitable for heavy-flowing products - integrated agitator - clean bottling - replaceable filling nozzles - Power up to 80 bags/hour at 25kg

Our screw technology offers innovative, goal-oriented and customised conveyor equipment specially designed to meet your needs.

Application areas: ##Measurement of continuous mass flows ##Weight-controlled filling of tanks, containers and similar Weighing product: All well flowing materials such as cement, rock powder, quartz sand, cereals, granulates. Accuracies: Between 0.1% and 1% depending on type and material feeding. Outputs: 200 kg/h to 40 t/h depending on screw size. Advantages: ##Small installation dimensions ##Universal application ##Can be retrofitted in existing systems Mode of operation: In the infeed area, the screw is pivoted horizontally transverse to the conveying direction. A force measuring device in the form of a measuring cell for weight measurement is generally installed in the area of the discharge. The product to be weighed is weighed during the transport from the infeed to the discharge. The accuracy of the screw weigh feeder basically depends on the filling level of the screw. Therefore there is an upstream dosing device (e.g. screw, rotary feeder, vibrating trough) before the screw weigh feeder.

KÖLLEMANN Screw-Conveyors have their field of application within the conveying of dusty, grainy and free flowing bulk-solids. They exploit their strengths with well flowing bulk-solids like sand, cement, granulate, ashes etc., but also face tough tasks like explosive, abrasive or adhesive bulk-solids. We will support you in any way in solving your conveying-problems. With our ingenious engineering as well as our rich experience, KÖLLEMANN Screw-Conveyors are suitable even for products which under normal circumstances would not be conveyable with screw-conveyors – this is ensured by means of our well-proven KÖLLEMANN Self-Cleaning-System.

KÖLLEMANN Screw-Heat-Exchangers have their field of application within the thermal treatment of bulk-solids, we offer specialized products for each particular field of application. KÖLLEMANN Screw-Heat-Exchangers cover the whole spectrum of process-technology, starting with cooling of bulk-solids like for e.g. bed-ashes from drying of sludges or pastures up to heating of for e.g. petcoke for the anode-lines of the aluminium-industry. Based on their design, KÖLLEMANN Screw-Heat-Exchangers differ significantly from the usual on the market available ones, as they use the proven Hollow-Flight-Principle, which unifies serveral advantages within: an significantly enhanced heat-exchanging surface, leading lower thermal-stress on the screw-flight – especially during cooling-applications as well as forced heat-transfer-medium guidance inside the shaft. The temperature range of the KÖLLEMANN Screw-Heat-Exchangers reaches from colling down from 1200°C up to heating to more than 200°C with heat-transfer-medium temperatures above 350°C. KÖLLEMANN produces the Screw-Heat-Exchangers in accordance with standards such as AD2000 or ASME BPVC Sec.8 div.1 to ensure an maximum of safety during the handling of the heat-transfer-medium.
