SPAANS screw conveyors

History

Approximately 100 years ago. Mr. Spaans, a local blacksmith, made his first screw pump to convey water. Since then, Spaans has manufactured more than 100,000 installations world-wide, conveying all kinds of products from sticky waste water sludge to products for the food and chemical industries.

In June 2004, Van Tongeren Kennemer took over the company’s activities concerning screw conveyors and associated equipment, including all know-how and personnel.

SPAANS special conveyor applications

Besides conveying material, other functionalities can be integrated in the design of a conveyor, such as dosing, extracting, cooling, heating, mixing, separating, diagonal and vertical conveyance.

Because of our vast experience in conveying bulk products, we can provide you with the best solution for every situation.

We have available a wide range of solutions to optimise conveyor systems for a specific application to prevent wear, leakage, breakdown, etc.

Dewatering Screw

Dewatering Screw

Dewatering screw conveyors are used to remove surface water.

Diagonal screws are used to remove water with gravity.

Pressurised screw conveyors are used to remove water with pressure.

Screw conveyor

Screw conveyor

Screw conveyors are used to transport bulk materials in horizontal, vertical or diagonal directions. Material and optional variables are the following: carbon steel, stainless steel, wear-resistant or low-friction screw blades, including discharge valves, flap valves, discharge sluices, intermediate bearing systems and much more.

Mixing, retention, conditioning, cooling, and heating screws

Mixing, retention, conditioning, cooling, and heating screws

Options / variables are the following: screw conveying, paddle mixers, ribbon mixers, perforated screw blades, internal flow for cooling and heating, pressurised mixers.

Design variables at your needs

The actual configuration of a screw conveyor or mixer depends not only on the type of (bulk)material to be handled, but also on aspects such as humidity, temperature, Atex zoning and the actual process requirements.

VTK/Spaans conveyors can be equipped with a range of blade types (full blade, ribbon, paddle blade or a combination of these), blade configurations (wear resistant, perforated blades, synthetic coating) as well as pitch and diameter variations. Furthermore, the screw conveyors are available with a range of inlet and discharge systems, and various types of housing (carbon or stainless steel, flexible housing, pressure-vessel design). Below are just 4 of many possible screw designs.
