Large Capacity Tumbler Sifter Three Dimensional For Amino Resins Moulding Plastic

Overview of Tumbler Screening Machine:

What is a tumbler screening machine? The tumbler screening machine is also called tumbler screen, tumbler screener, tumbling screen, tumbling screener, tumbler sieve, swinging screen, swinging sieve, rocking sieve, shaking sieve machine etc. Tumbler vibrating screen machine is a new and high-efficient sieving machine machine which is designed to meet the requirements of large output and high-density sieving. It make use of artificial sieving movement successfully (its sieving precision, sieve efficiency and sieve life is 5~10 times of common sieve machine), and suitable for all the fine, ultra-fine powder and special materials, particularly suitablefor materials which are difficulltto deal with.

Unlike a typical vibratory or gyratory screening machine, the tumbler screening machine incorporates a unique three-dimensional tumbling motion providing the gentlest screening possible. This motion prevents delicate, friable material from being broken resulting in less undesirable fine generation and dust levels. Even the most difficult materials, which tend to blind screens, are screened efficiently by utilizing the proper anti-blinding systems including motor driven brushes and/or air knives that are unique to tumbler type screening machines.

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.

The tumbler screening machines are used for bulk material grading, safety screening, and dedusting in all industrial sectors. They are particularly well-suited to the fine and extremely fine screening of dry bulk materials and precise grading with up to 6 particle sizes.

Working Principle of Tumbler Screening Machine:

While the tumbler screening machine is running, its radial inclination ensures that the material being screened moves from the center of the screen outwards, while its tangential inclination makes the material move in circular fashion on the screen. The interaction between the two resulting forces makes the particles being screened move in a spiral pattern on the screen fabric, ensuring that the particles stay a long time on the screen. This, in turn, enables the machine to achieve an optimum level of grading accuracy with respect to the particle size ranges while simultaneously minimizing oversize and fines contamination.

The movement of a tumbler screener is usually compared with simple hand screening. The product is continuously fed into the center of the top screen, from where it spreads out evenly to the outside across the entire screening surface. The finer particles fall through the screen near the center and the coarser ones successively towards the periphery. The material is moved in a spiral pattern with increasing acceleration of the particles the further they are from the centre, with the result that even those particles which are almost the same size as the screen mesh are screened. All the separated fractions are discharged through the lateral outlets. The screening process is repeated again and again on each deck.

Features and Characteristics of Tumbler Screening Machine:

1. Large capacity than normal vibrating screen.
2. The accurate is six stage separation, and screening efficiency is highly from 95% to 99%.
3. Using silicone rubber ball, ultrasonic device such as efficient clean network system.
4. Without blocking mesh net,Sealed dust and safe operation.
5. The acceleration is 4.5 times lower than the vibrating screen,so the screening parts life increase and reduce maintenance.
6. With low noise which is less then 75 db. Optimize the weight balance, foundation dynamic load is low.

Pneumatic Lifting Device BALANCE IS IMPORTANT !!
