Spiral Engineering products

Shaftless spiral conveyors are the best way to transport sticky and sludgy materials.  Versatile and economical, they are simple and trouble-free.

Shafted spiral screw conveyors have been used for conveying bulk material since the industrial revolution. Simple, economical and reliable, this old principle invented by Archimedes is still the best way to transport free-flowing materials.

The Spiral Press is composed of a shaftless spiral screw that conveys material in a pressing zone for compacting and dewatering. The spiral screw applies pressure within the press zone which is enclosed in a wedge wire basket. Material is retained at the end by a press door using weights, spring hinges or cylinders. Presses are inclined installations and have a drainage zone for extracted water.

The Spiral Compactor is composed of a shafted spiral screw that conveys material in the compaction area. The spiral screw applies strong pressure within the compaction zone, pushing the material into a friction pipe. The end of the spiral shaft is supported by compacted material. Some models also have a drainage zone to extract water.

Spiral Mixers are ideal for dry materials or material with substantial liquid contents. Rapid and gentle fine mixing of small percentages of ingredients with bulk material is achieved with one or two spiral of type paddle or ribbon. Operation is clean and dust-free, and ensures a continuous thorough tumbling for a homogeneous mixing.

The Spiral Sand Separator is designed to collect grit or other types of heavier sediment particles and separate them from water and organic material. Water to be cleaned passes through the charging inlet and is let into the decantation hopper, where an underflow baffle will create an even laminar flow for the sedimentation of solid particles. The shaftless spiral screw will transport the washed sediment sand at a low speed of rotation to a collection container, and the treated water comes out of the discharge spout.

Archimedes was a mathematician and an inventor from Ancient Greece. He left his mark on his era with such inventions as the catapult, the lever and the screw. Archimedes was able to show that when a screw turns in a cylinder, it transports the material in front of it. This proven principle leads to a trouble free design which can transport slushy and sticky material with ease. Over the past years, SPIRALENGINEERING has refined and optimized the manufacturing processes for its Spiral Screws. We are now manufacturing ourselves screws of virtually all sizes. The spirals are in general made of high strength low alloy steel at different flight thickness, but other materials can be used like AISI, ASTM, 4140, 8620, SS304L, SS316L, incoloy, hardox and even aluminium, to name a few.

SPIRALENGINEERING provides various replacement parts for conveyors and spiral-related equipment. The high quality and precision parts are manufactured according to the characteristics of the equipment it’s made for, specifically to the needs of our clients.
