What Is a Tumbler Screening Machine?
The Tumbler Screening Machine, also known as the swing vibrating screen or shaking screen, is a screening equipment designed to meet high production and high-precision screening requirements. It is primarily used in industries such as chemicals, food, pharmaceuticals, mining, building materials, and recycling. It employs a low-frequency screening principle that mimics manual shaking, generating horizontal and throwing three-dimensional rolling motion through a low-speed V-belt drive. This motion imitates manual screening actions, enabling uniform dispersion of materials and spiral axial propagation. The eccentricity is adjustable from 25 to 40mm, and the low-speed V-belt drive speed is adjustable from 120 to 360rpm to adapt to different material properties.
The equipment uses bounce balls, rotating brushes, or ultrasonic screen-cleaning devices to prevent screen hole blockage. The screening efficiency reaches 90%-99%, with a relatively large processing capacity per unit area. It supports multi-layer screen configurations (typically 1-5 layers). During operation, it has a low acceleration and noise level, usually below 75 decibels (some models can maintain 60-70 decibels). It features a fully enclosed dust-proof structure and a quick screen-changing system.
What problems can the tumbler screening machine solve for you?
In short, if you are facing challenges such as high material breakage rates, high production requirements, and short sieve mesh lifespan, the Jiarui tumbler screening machines can help you address the following issues:
- The tumbler screening machine replaces manual sieving. It sieves gently, minimizes damage to materials, and results in a low material breakage rate.
- The tumbler screening machine can achieve a sieving accuracy of 90% to 95% and can easily process ultra-fine powders as fine as 500 mesh (0.028mm).
- It has a large unit processing capacity and high efficiency. The unit area processing capacity is 3 to 5 times that of a conventional vibrating screen, and one machine can replace 3 to 5 machines.
- It can be paired with various net-cleaning devices such as bounce balls and ultrasonic cleaners to fundamentally solve the screening challenges of high-viscosity and easily clogging materials.
- Operates more smoothly, with a sieve life span 5 to 10 times that of conventional equipment, significantly reducing operating costs.
Working principle
Instantaneous motion is a combination of radial displacement and circular motion around this displacement (helical motion). An adjustable eccentric exciter generates nonlinear three-dimensional motion, causing the material to undergo similar approximate manual operation motion, thereby achieving the screening purpose. With the operation of screening accessories, a more ideal screening effect can be obtained; it is suitable for spherical and cylindrical.
Ways to clean the sieve
- Bouncing Ball Cleaning: Food-grade rubber or silicone balls bounce on a perforated plate beneath a screen, striking the metal mesh to reduce clogging of the screen holes. This system is simple to use and easy to maintain, suitable for most granular materials.
- Ultrasonic Cleaning: High-frequency ultrasonic waves are transmitted to the screen, cleaning it while significantly increasing production capacity. It is suitable for most fine, high-volume, and difficult-to-screen materials.
