Siebtechnik continuous centrifuges and industrial screening equipment in global engineering

SIEBTECHNIK GmbH has designed and manufactured heavy-duty machinery for solid-liquid separation and bulk solids grading since 1922.

Operating globally under the SIEBTECHNIK TEMA umbrella, the enterprise provides continuous decanters, filtration centrifuges and heavy vibrating screens for mineral processing, chemical synthesis, metallurgical refining and industrial recycling facilities worldwide.

Each machine series is engineered for continuous multi-shift production under heavy mechanical stresses and aggressive chemical exposure.

High-strength stainless alloys, specialized tungsten wear protection and tuned isolation springs ensure dependable process availability and long maintenance intervals in demanding production circuits.

CONTURBEX screen scroll filtering centrifuges: operating principle and differential drive kinematics

CONTURBEX continuous screen scroll centrifuges provide efficient filtration and mechanical dewatering of crystalline, granular and polymeric suspensions.

The core kinematic configuration features a conical screen basket and an internal conveying scroll rotating coaxially at a regulated differential velocity driven by heavy-duty planetary or cycloidal gearboxes.

Controlling scroll differential speed establishes optimal solids retention time across the dewatering and washing zones of the basket.

Conveying scroll flights are reinforced with sintered tungsten tiles, while conical screen baskets incorporate precision slotted wedge wire segments with tailored apertures.

SHS pusher centrifuges: multi-stage filtration and cake washing for crystalline materials

Siebtechnik SHS single-stage and two-stage pusher centrifuges are built for high-capacity dewatering of free-draining crystalline and granular solids requiring intensive purity washing.

The unit comprises a rotating cylindrical slotted basket paired with an axially reciprocating pusher plate actuated by an integrated hydraulic cylinder.

The reciprocating pusher strokes gently advance cake along the cylindrical screen surface toward discharge without grain breakage. Integrated multi-port spray headers apply uniform washing liquor across the solids bed to displace mother liquor efficiently, optimizing chemical separation performance.

TS solid-bowl decanters and Conthick hybrid separation units for fines and sludges

Solid-bowl scroll decanters of series TS and DZ provide continuous centrifugal sedimentation of fine slurries, generating clarified centrate and thickened sludge cake.

Conthick hybrid machines integrate an initial solid-wall sedimentation drum with a final conical screen basket section for mechanical dewatering of delicate solids.

Centrifugal sedimentation under high G-forces requires durable protection across product-contact areas.

Rotor journals are supported by heavy-duty spherical roller bearings with forced oil lubrication, while solid cake discharge ports feature replaceable tungsten carbide sleeve liners to counter abrasive erosion.

Circular and linear motion screening machines: heavy-duty grading of bulk solids

Siebtechnik circular and horizontal linear motion screens deliver precise sizing, grading and dedusting across mineral and chemical aggregate applications.

Vibration is generated by box-type unbalance exciters featuring forced gear synchronization to maintain dependable oscillation strokes under surging feed rates.

To isolate dynamic vibrational forces from surrounding support structures, screening decks are suspended on heavy steel coil springs or elastomeric air buffers.

Decks accommodate modular polyurethane panels, molded perforated rubber mats or longitudinal tensioned wire cloths with quick-acting clamping bars.

Electronic elliptical motion screening machines and routine predictive servicing

Elliptical vibrating screens with electronic speed and throw angle adjustment represent an advanced development allowing operators to modify stroke dynamics without mechanical counterweight adjustments.

This capability permits rapid tuning to accommodate variations in feed moisture, sizing distribution or throughput demands.

Routine servicing of centrifuges and screening decks involves vibration trend monitoring, basket slot gap measurement, bearing temperature verification and seal renewal.

Selecting matching parts by nameplate serial codes prevents unexpected downtime and maintains processing productivity across operating facilities.
