Tumbling Screen Machine for Mineral Powders with Pneumatic Lifting Device

Overview of Tumbling Screen Machine for Mineral Powders with Pneumatic Lifting Device​:

The tumbling screen machine is also known as tumbler screen, tumbler screener, tumbler screening machine etc. It is typically used to sieve extremely ine and/or lightweight products, such as food flour, micronised materials, mineral powders, plastic powders etc.

  When using a typical vibrating screen equipment, you may notice that the product would rebound and tend to remain suspended, hardly coming into contact with the sieving mesh. This would result in the inefficient separation of the different particle sizes and anyway in extremely low hourly rates. 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.

  Tumbler screening machine is an efficient sieving machine, which is designed to meet the large output capacity, high-density sieving of the manufacturer. The simplest screening is using your hands with the staring of your eyes. Tumbler screening is the mechanical simulation for the simplest one, it is the most effective method to stimulate the principle of artificial screen movement (screening accuracy, efficiency, life of screen mesh are 5 to 10 times than the common circular screen). It conforms to all range of fine and ultra-fine powder and particle materials, especially suitable for processing hard materials.

Working Principle of Tumbler Screening Machine for PVC Plastic Powder​​:

  The tumbler screener utilizes the humanoid screening principle. To imitate the movement of artificial screening action and do three-dimensional circular motion, skillfully combine the sieving (planar circular motion) and winnowing (upward parabolic motion), establish horizontal and throwing three-dimensional tumbling movement, make the material in the screen surface appear involute spiral movement. The material takes a relatively long distance across the relative area, and the landing screen time of the material is more than 85%, improving the screen through rate. The screening accuracy is as high as 90%~99%, increasing the yield.

  According to the physical properties of the material and the different screening requirements of customers, we can adjust the independent and adjustable rotate speed, eccentricity, radial force, tangential force, so as to change the material stay time on the screen surface and the moving route to achieve the best screening effect.

1. The basic rotary motion is similar to the manual screening. The eccentricity is adjustable from 25 to 40mm, and the low-speed V belt drive is adjustable from 120 to 360rpm.
2. The stay time of each product can be adjusted by the radial and tangential direction of the tumbler screening.
3. Therefore build horizontal level and throw three - dimensional rolling motion. The material is distributed evenly throughout the screen from the center to the outside edge, and then the screw travels to the axial transmission. Thus, the small particles complete the screening process.
4. The horizontal and vertical acceleration increases with the motion of the particles, and the particles close to the size of the mesh are successfully separated. The larger particles are transported to the exit and the outlet is controlled by a adjustable guide device, which is another factor that controls the duration of the material's stay.
5. And the process is repeated between each sieve.
