Types of vibrating screens include coarse screens (linear vibrating screens), fine screens (rotary vibrating screens, ultrasonic vibrating screens, and oscillating screens), and mining screens (mining vibrating screens, circular vibrating screens, and banana screens). For even finer screening, there are also ultra-fine screens (airflow screens and test sieves). These are commonly used for screening, filtering, and removing impurities from powders, granules, and bulk materials. The following provides a detailed introduction:

How many types of vibrating screens are there?

Coarse Screening Equipment

Linear vibrating screens are used for rough impurity removal and classification of non-sticky dry powders and granules within 400 mesh. They are commonly used for screening and grading medium-to-coarse granular materials such as sawdust, quartz sand, ore, coal, peanuts, soybeans, sesame seeds, activated carbon, fertilizers, plastic pellets, and river sand. Hourly throughput ranges from 0.12 to 30 tons, with screening efficiencies as high as 96%. The models of linear vibrating screen can be divided into type 515 (500mm*1500mm), type 520 (500mm*2000mm), type 525 (500mm*2500mm), type 612 (600mm*1200mm), type 1025 (1000mm*2500mm), type 1030 (1000mm*3000mm), type 1224 (1200mm*2400mm), type 1525 (1500mm*2500mm), type 1530 (1500mm*3000mm), etc. More models can also be customized according to needs; the screen has 1-5 layers to choose from, which can screen the material into 2-6 different specifications. The material is carbon steel or stainless steel.

Fine Screening Equipment

When fine screening is required, rotary vibrating screens, ultrasonic vibrating screens, and tumbler screens are suitable. These devices can screen, remove impurities, and filter materials within a 10-623 mesh range. Ultrasonic vibrating screens can handle fine powders, sticky materials, or easily agglomerated particles that are difficult for rotary vibrating screens to screen. Tumbler screens are the preferred choice for high-volume fine screening.

Rotary vibrating screens can screen powders, granules, and liquids within a 500 mesh range. They are suitable for processing starch, soy milk, soy sauce, MSG, resin powder, coatings, traditional Chinese medicine powder, electromagnetic materials, plastic granules, laundry detergent, and other materials. Capacity ranges from 100 kg to 3,000 kg. Using a vertical vibrating motor as the excitation source, the material undergoes three-dimensional motion on the screen surface: horizontal, vertical, and tilted, achieving high screening accuracy. Rotary vibrating screens are available in carbon steel, stainless steel, and plastic. Common models are categorized by screen diameter: 400mm (15”), 600mm (24”), 800mm (31”), 1000mm (39”), 1200mm (47”), 1500mm (59”), 1800mm (70”), and 2000mm (78”). They are also available with one to five screen layers (though three layers offer the best performance).

Ultrasonic Vibrating Screen integrates an ultrasonic screen cleaning system with the Rotary Vibrating Screen. High-frequency vibrations break down the surface tension of fine powders, with a vibration frequency of up to 36,000 vibrations per second (compared to 1,460 vibrations per second for standard models). This effectively solves the screening challenges of ultrafine powders below 20μm that are highly adsorbable, prone to agglomeration, exhibit high static charge, are highly refined, and have a low specific gravity. It can be used for screening and removing impurities from materials prone to electrostatic attraction, such as nanomaterials, graphene, pharmaceutical powders, battery materials, alloy powders, and electromagnetic powders. Its models and levels are the same as those of the rotary vibrating screen.

Tumbler Screen utilizes an anti-artificial screening principle, with the material undergoing a planar rotary motion on the screen surface. This gentle screening method is particularly suitable for screening and removing impurities from fragile, sticky, spherical, flaky, and irregularly shaped materials such as flour, powdered sugar, and resin granules, maintaining particle integrity and preventing breakage. With a throughput of up to 50 tons/hour, it is the highest-capacity fine screen. Common models range in diameter from 600mm to 2600mm, and are made of stainless steel and carbon steel.

Mineral Screening Equipment

When processing large, high-hardness mining materials with particle sizes ranging from 5-300mm, we offer mining vibrating screens, circular vibrating screens, and banana vibrating screens. These meet the harsh working conditions of the mining and metallurgical industries.

Circular vibrating screens are available in two series: the YK and YA. They utilize a circular motion trajectory with adjustable amplitude and are available with 1-8 screen layers. They can process a variety of mineral materials, including ores, alloy powders, welding rod powder, manganese dioxide, electrolytic copper powder, refractories, kaolin, lime, alumina, and quartz sand. The YK circular vibrating screen has a mesh size range of 5-150mm and a processing capacity from 80t/h to 150-650t/h (3YK3070 model). The YA model has a slightly smaller processing capacity of 50-280t/h.

Banana screen (also known as a banana-type vibrating screen) features a screen surface with multiple inclination angles (gradually decreasing from 34° at the feed end to 10° at the discharge end), maintaining a stable material flow rate. This design increases the processing capacity by 1-2 times compared to conventional screens of the same surface area. It is commonly used for screening materials with particle sizes under 300mm, such as sintered ore, coal, limestone, crushed stone, gravel, and metallic and non-metallic ores. The ZXD series banana screens have a processing capacity ranging from 80-400 t/h (ZXD1560) to 300-1350 t/h (ZXD3690). They feature high vibration intensity (9-12mm), screening efficiencies exceeding 95%, and can accommodate up to six screen layers.

Fine Screening Equipment

For ultra-fine screening and laboratory particle size analysis, we recommend the Centrifugal Sifter and Test Sieve.

Centrifugal Sifter can be used to sieve powder materials within 800 mesh, primarily removing unwanted particles and breaking up clumps. Its high-speed rotation generates a powerful centrifugal force to separate materials that do not meet the required size requirements. It is commonly used for ultrafine powders with fiber, high viscosity, low specific gravity, and static electricity, such as heavy calcium powder, flour, hawthorn powder, traditional Chinese medicine powder, graphite powder, and rubber powder. Hourly output ranges from 1 to 15 tons, and materials available include carbon steel and stainless steel.

Test Sieve is a laboratory device used for particle size analysis and classification of materials or samples such as powders, bulk materials, and suspensions. It can quickly and efficiently measure solid particle sizes from 125 mm to 20 microns. Available with 1 to 13 screen layers, it can separate materials into 2 to 14 particle size segments. Common models include diameters of 75 mm, 100 mm, 200 mm, 300 mm, and 400 mm. Screens include woven metal, perforated plate, and electroformed mesh, with round and square openings. It is commonly used for testing materials such as cement clinker, coffee, chemicals, fertilizers, abrasives, flour, grain, metal powder, minerals, nuts, plastics, sand, seeds, and soil.

Different types of vibrating screens have varying prices. The most expensive is the banana screen, costing over $100,000, while the cheapest is the test screen, costing only a few dozen dollars. The choice depends on the material properties and product requirements. We can also customize our products to meet your needs.
