As a new generation of high-tech screening equipment with excellent screening capability and precision, it is one of the highly-efficient large screening equipment which can compete with German screening technology. It possesses features of low fault rate, low breakdown rate, low utilization cost, high production capability, high precision and high efficiency. It is applied to the granular level between 1mm and 25μm and can be used in eight layers at most to product nine granular sections at most, which makes it more suitable for highly-precise screening of refined powder.
It is modeled after manual screening principles, super-long non-fault operation time, possess very excellent screening precision;
It can be equipped with brush, air-brush, scraper, ultrasonic vibrator and bouncing balls to avoid net blockage and guarantee the continuity of screening process;
It can ascend or descend gas cylinder to make it more convenient for replacing screening net;
Round building-block assembly structure makes it easy for assembly and disassembly;
The material discharging outlet can rotate in 360°;
Various screening net structures, which can be assembled and wholly stuck together;
Flexible tumbling screening will not damage the original granular structure of materials;
It will not easily produce static electricity and is applicable to screening of materials which are inflammable, combustible and easily produce static electricity;
The screening net is more durable than that of vibration screener and has a longer useful life;
The noise is reduced to 75dBa. The enclosure makes it more environmentally friendly.
Balance is very important
Adhered screening net and enclosure structure
AAREAL Tumbler screener is modeled after the manual screening principle and simulates manual screening motion to make three-dimensional round movement. It elaborately combines screening (planar round movement) with winnowing (upward projecting movement). The combination of round movement and upward projecting movement establish the horizontal and projecting three-dimensional rotating movement to make the materials move in an open spiral direction. Consequently, the materials will travel longer distance in the same area. The time for the materials to land on net is normally greater than 85%, which improves net penetration rate and increases the screening precision high to 90-99%, thus bringing up the production amount.
Relevant independent and adjustable rotating speed, eccentric distance, radial force and tangential force can be adapted according to the material’s physical properties and client’s various screening requirements to change the residence time and movement trajectory on the screening net in order to achieve optimal screening effect.
Screening parameter control figure
Only when the optimal operation setting parameters are memorized, optimal operation can be achieved repeatedly at any time to guarantee your product quality and achieve optimal screening effect.
Advanced and various anti-blockade technologies as well as diverse cleaning methods prevent the screening net from blockade to guarantee the continuity of screening process.
1) Bouncing ball cleaning equipment
Hole plate is placed under the screening net. Silica gel balls and PU rings are placed between the hole plate and the screening net in order to bounce and support the net as well as bounce out the materials blocking the net.
2) Rotating brush cleaning equipment
Rotating brush is rotating below the screening net driven by decelerator to bounce out the materials blocking the net.
3) Compressed air cleaning equipment
The compressed air or other gases are led to the air-injection rotating arm below the screening net through the air flow room at the center of screener. The air flow blows the materials from downwards with a speed of 120m/s to bounce out the materials blocking the net. It is applied to adhesive materials which produces static electricity and are difficult to be screened.
4) Rotating brush and compressed air cleaning equipment
5) Elastic scraper cleaning equipment
Elastic scraper is rotating on the screening net driven by decelerator to destroy powder mass and fake granules in order to screen materials.
6) Ultrasonic cleaning equipment
Ultrasonic high-frequency vibration is added to the screening net, which can effectively clean the screening net.
Special screening structure satisfies special purposes
1) Avalanche screening
There are two layers of screening nets with the same structure. Materials enter the first screening net for screening. Those materials which are not yet screened in the first layer will enter the middle place of the second screening net through channels. Consequently, the screened materials travel a longer distance on the net, which increases the screening precision.
2) Pre-screening+avalanche screening
One or two layers of coarse screening nets can be placed on the avalanche screening net to pre-screen large granules. The fine screening process will be accomplished by avalanche structure.
3) Double amount screening
Materials are allocated to two screening nets with the same structure through special material tube and are divided into granules of two levels to accomplish the screening requirements for larger production amount.
4) Assembly screening net
Screening net is divided into many small parts to facilitate installing and replacing screening net.
