Unique tumbling type motion
The adjustment of the machine in response to the product to be screened provides an exactly defined three dimensional eccentric motion pattern with radial and tangential inclination. During operation of the tumbler screening machine the radial inclination causes the product on the screen to move from the centre towards the edge of the screen while the tangential inclination leads to a circular motion of the product on the screen. The combined impact of both of these forces causes the product in a helical motion of upon the surface of the screen and therefor to a relatively long retention time. This provides an optimized result on fraction separation while at the same time minimizing the amount of remaining outsize particles.
ATEX approvals
ATEX approved machine models are available i.e. when operating the machine with explosively hazardous dust products or operating the machine in explosively hazardous areas further in presence of explosively hazardous atmospheric ambient outside or inside of the machine. Following explosion proof design certifications can be issued as per EC-type examination certificate IBExU12ATEX1095X according to RL 94/9/EG:
• For dry screening: II 1 / 2 D c T X
• For dry screening with additional Category 2G related to the equipment outside: II 1D / 2DG c IIB T X
• For dry screening in presence of combustible gases/vapours (hybrid-mixtures): II 1DG c T3 / 2DG c IIB T X

Our largest machine
The tsi 290 is our largest tumbler screening machine. Providing a screen diameter of almost 3 metres the tsi 290 offers an extra screening area
of 20% in comparison to the TSM 2600 model. In addition the low overall height makes the tsi 290 the most economical solution in many applications
when expanding plants where the previously available screening capacity is no longer sufficient.
Continuous mesh cleaning guarantees highest screening quality
Due to its round body and its unique drive system the tumbler screening machines are particularly suitable for operating with various types of mechanically driven rotating mesh cleaning
devices.
The screen is continuously cleaned during the screening process ensuring high screening quality and a constantly high product flow.
Bouncing balls
The bouncing ball mesh cleaning device available in several variations is the universal cleaning system for numerous granular products.
Ultrasonic
Ultrasonic screen cleaning is particularly suitable for applications with fine mesh apertures ranging from 20 to 1,000 μm.
Combined ultrasonic and balls
For a maximum of product throughput trough the screen and permanent mesh cleaning.
Air Flow
The impact of high speed air flow provided by rotating arms placed directly under the screen is blowing out particles caught in the mesh which is an ideal solution i.e. for sticky products.
Combined ultrasonic and air
Applicable when processing products extremely critical to screen such as fine plastic powders etc.
Conical rolling brushes
Rotating conical brushes placed right under the screen clean gentle and with low-wear. Typically used for spherical products blinding the mesh.
Combined air and brushes
This is an effective cleaning system i.e. for greasy or electrostatically charged products.
Passing/straining unit
Allow gentle straining i.e. disagglomeration
of products like instant coffee by using steel or
plastic spatulas, rotating on top of the screen.
