Why choose Gyratory Combination Multi-Layer Screen

One machine replaces three – save space and electricity

Gyratory combination multi-layer screen breaks through the traditional screening mode:Traditional screening equipment is either a single-layer vibrating screen.

Which requires multiple devices to be connected in series to complete multi-level screening (for example, wheat cleaning requires three devices: large impurity screen, medium impurity screen, and fine impurity screen), or a single-layer screen that “screens all the way to the bottom”, and the impurities are not completely separated.

ACME gyratory combination multi-layer screen innovation lies in the collaborative design of “multi-layer screen + gyratory motion”: the screen drum has 3-5 layers of adjustable screens built in (the number of layers is customized according to material requirements).

During the gyratory process of the screen drum, the material is stratified due to gravity and centrifugal force. Large impurities are thrown to the screen wall and fall into the first layer of impurity discharge port, and medium impurities pass through the first layer of mesh and fall to the second layer.

Finally, the clean grain is discharged from the last layer of screen – one device can complete the three or even four levels of screening of “large impurities → medium impurities → fine impurities”.

It is equivalent to compressing the work of three traditional devices into one, directly saving 60% of the equipment space and 40% of energy consumption.

Actual measured data from a feed factory showed that after using it to replace the original single-layer vibrating screen + flat screen combination, the workshop space utilization rate increased by 35%, and the power consumption per ton of grain sorting dropped from 1.2 degrees to 0.7 degrees.

Drum primary screen VS gyratory combination multi-layer screen

The cylindrical primary cleaning screen is a “single-layer coarse screen” that relies on the rotation of the screen drum to remove large impurities (such as straw), but cannot handle broken wheat and fine dust;

The gyratory combination multi-layer screen is a “multi-layer fine separation” that filters through 3-5 layers of screens, and the large, medium and fine impurities are returned to their respective positions, and the net grain impurity rate is reduced from 1% to below 0.3% (in line with high-end flour standards).

More importantly, its screen can be quickly disassembled and replaced (a set can be replaced in 5 minutes). When cleaning corn, a large-hole screen can be replaced, and when processing soybean meal, an anti-sticking screen can be replaced. The flexibility is far superior to the “fixed screen hole” of the cylindrical primary cleaning screen.

Working principle of gyratory combined multi-layer screen

Gyratory combination multi-layer screen is composed of a frame, a screen body, a drive transmission system, a suspension system, a grain feed box and an output box, a screen mesh and an air suction channel, etc. It works in a plane rotation motion and has appropriate screen holes and screen plates to remove impurities from the product or to grade one grain with different particle sizes to another.

The material enters from the high end of the screen drum and spirals down with the 6-10 rpm gyration of the screen drum. Large impurities are thrown toward the screen wall due to their large size and fall into the first-layer impurity discharge port;

Medium impurities pass through the first-layer mesh and fall to the second layer, where they are intercepted by smaller meshes; clean grain and fine dust continue to pass through the third-layer screen;

Finally, clean grain is discharged from the last-layer discharge port, and fine dust enters the dust collection system through the last-layer mesh – the whole process is like a “screen tower” filtering layer by layer, completing multi-level sorting in one go.

Gyratory combination multi-layer screen features

— The feed end, equipped with a multi-channel distributor, evenly distributes material onto the screen plates, ensuring a stable and evenly distributed material flow rate, enhancing screening and grading performance.
— The metal screen frame offers a thin, high-strength, and rigid surface, ensuring a flat screen.
— The screen frame and body side panels are bolted together, integrating the screen frame and screen box into a single unit and providing superior overall strength.
— The screen plates are easily assembled and disassembled, and the same mesh size is interchangeable.

Application scenarios of gyratory combined multi-layer screen

In addition to traditional grain processing, the potential of Acme’s gyratory combination multi-layer screen is extending to more fields.

In a nut processing factory in Henan,gyratory combination multi-layer screen used to sort walnut kernels – the first layer of screen intercepts shell debris, the second layer screens out broken kernels with a diameter of less than 5mm (for processing walnut powder), and the third layer retains complete walnut kernels (for packaging finished products). The sorting efficiency is 10 times higher than manual picking;

Gyratory combination multi-layer screen The three core values

1.Efficient multi-stage screening, doubling production capacity

The multi-layer screen mesh operates synchronously, completing coarse, medium and fine multi-level classification at one time, eliminating multiple screening processes; the rotary design accelerates material flow.

The processing capacity of a single device is increased by more than 30%, greatly shortening the production cycle and meeting the high-efficiency needs of large-scale grain processing.

2. Accurate grading and quality control to enhance value

Gyratory combination multi-layer screen specifications and number of layers of the rotary combined multi-layer screen can be customized (such as flexible adjustment of 2-5 layers), realizing millimeter-level particle size differentiation (such as 2mm/5mm/8mm multi-level);

Precisely separate broken rice, impurities and complete grains, help to price grain by grade (such as 15%+ premium for first-grade rice), and directly increase product added value.

3. Durable and reliable, cost-saving and long-lasting

Optimized rotary structure + anti-blocking screening design to reduce frequent downtime caused by material blockage; key components adopt high-strength wear-resistant technology to adapt to high-humidity and high-mix conditions commonly seen in grain processing;

Maintenance only requires simple cleaning or replacement of wearing parts, which reduces the maintenance frequency by 40% compared to traditional equipment, and the comprehensive cost of long-term use is more controllable.
