Siebtechnik Tema B.V. products

The SIEBTECHNIK TEMA CONTURBEX screen scroll centrifuge is a machine concept for demanding tasks that has been proving its worth for decades. The CONTURBEX is a continuously operating filtration centrifuge for a broad range of applications. We achieve this flexibility by means of a centrifuge scroll driven at a differential speed.

The Siebtechnik Tema SHS pusher centrifuge has established and proved itself as a modern high-performance machine in many areas of industry. It does its separating work in crystalline applications reliably. Siebtechnik Tema is also among the leading suppliers of pusher centrifuges in polymer products.

With the SIEBTECHNIK TEMA HSG vibrating centrifuge, you can continuously dewater the largest quantities of solid material in the world.
Coarse salts, sea salt, potash, coal, sand or whatever: the HSG continuously dewaters the largest quantities of solid material reliably, fully automatically and self-regulating. Even with fluctuating feeds the HSG does its work at the lowest possible energy cost. Steady and continuous operation and a maintenance-friendly construction are the results of over 70 years of consistent further-development of SIEBTECHNIK HSG centrifuges.

The SIEBTECHNIK TEMA decanter centrifuge is a continuously operating solid-bowl worm centrifuge in tunnel or pedestal bearing design. Our decanters are individual, functional and versatile. They offer highly efficient separation of even the finest solid materials together with a nearly complete clarification of the liquid phase.

The SIEBTECHNIK TEMA TWINCONE decanter centrifuge is a decanter centrifuge with a second bowl cone fitted downstream.

The SHORTBOWL decanter centrifuge is designed overhung-mounted. Because of the special geometry of the rotating parts it is highly suited for the separation of fine solid particles having a specific gravity that is very different from the liquid phase. The design principle with its strict separation of process and drive unit makes this decanter ideal for applications in pharmaceutical or food manufacturing operations (CIP standard). This machine concept also means that the decanter can be used in high-temperature areas or for pressure-tight processes. From laboratory standard through to rough work in the primary materials industry the SBD decanter is ideally suited. Versions in special materials, explosion protection and inert gas overlay or hot gas blanketing have been part of our offering for over 50 years. We also increase operational reliability by fitting oil-circuit lubrication for all bearings, including gear unit and scroll bearings. 

The vibrating screen centrifuges from Siebtechnik Tema use eccentric weights to produce a uniform vibration behavior, resulting in less power consumption to save you money. The vibrating screen centrifuges offer more capacity thanks to adjustable axial vibrations and amplitude The vibrations are generated by 2 counter-rotating imbalance weights.This gives vibrations in the resonance range, slightly less than natural vibrations. The amplitude of the empty machine can be adjusted by setting the bias on the rubber buffers. As a result, the amplitude is automatically increased, which reduces downtime due to normal product shocks. Table with specifications for available models:

State-of-the-art coal centrifuges designed and developed from decades of experience. The Screen / Worm coal centrifuges (Conturbex) from Siebtechnik Tema are designed for fine coal dewatering with considerably more capacity per energy unit than other competing models. The patented, worm design ensures less particle breakage, prevents balance issues through uniform material distribution and extends the life of the screen. Siebtechnik Tema have developed this machine design into an extremely versatile screening centrifuge that is suitable for a wide variety of separation requirements.

A variety of microbial reduction techniques are routinely employed within the industry for reduction of pathogens. These techniques include: fumigants (ethylene oxide and propylene oxide), steam, and irradiation. Each technique has advantages and limitations in effectiveness, quality impact, and consumer acceptance.

Rolled baking oven belts are a special product when it comes to material quality, spiral structure, tolerances and applicational requirements, thus helping you to reach easy installation and maintenance with low costs as well as a long operational lifetime. Apart from that it is the only Z-belt for which a special cleaning device, making brush systems more efficient, has been developed. The spiral structure of our rolled baking oven belts is equal, with good angularity and always with the same number of spirals along the whole belt length. This advantage of the invariable mesh number is used by CLEANBELT?® in breaking the dirt in the belt’s mesh structure without missing a mesh. The oven’s brush systems to follow can then, if used adequately, remove the dirt better and more effectively.
