1. Tumbler Screening Machines Introduction
Basically the movement of a Tumbler Screening Machine can be compared to natural hand screening. For the control screening, fractionating and de-dusting of dry, powdered and granular products. Particularly suitable for high feed rates and multi-deck separations of fine, lightweight products which are difficult to screen.
1) Description
Tumbler sieve is a kind of evolving from artificial screen. The movement of circular motion and toss (upward parabolic movement) are fully embodied. By adjusting the Radial angle and Tangential angle to change the amplitude of circular motion and toss. Advanced technology and design for better performance in round screen ! The motion of tumbler sieve is double pendulum movement that generated by ordinary vertical motor drives eccentric wheel. The material forms a regular gradually grounding parabolic motion by adjusting the radial angle and tangential angle.
2) Customers are to be found in all sectors with a widely varying range of products such as:
Animal feed
Building materials
Chemicals
Fertilizer
Food, beverages and tobacco
Metals
Minerals
Pharmaceuticals
Plastics and rubber
Recycling
Wood

4. Options:
1) ATEX version
Use in a potentially explosive plant environment.
2) Bouncing ball cleaning
Use with grainy products. There are balls located between one perforated floor and the screen fabric, which strike the screen fabric from below.
3) Brush cleaning
Use with crystalline or spherical products. Rotation under the screen.
4) Ultrasonic cleaning
Use in the ultrafine mesh range. The ultrasound is input into the screen using resonators.
5) Air cleaning
Use with sticky products. Air blowing out of rotating nozzle arms clears the screen fabric.
6) Lifting devices
Quicker access to the screening inserts.
7) Hygienic design
Machines are available with a high-quality "pharmaceutical finish".
8) Air brush cleaning
Use with greasy or electrostatically charged products.
9) Special outlets
Individual adaptation to upstream or downstream machinery.
5. Projects On site:
1) Rubber powder screening at 45 mesh
2) Rice flour screening
