Types of Screening Machine by Application & Design | Ruijie China Screening Machine Factory

When it comes to reliable screening equipment, a professional China screening machine factory is your top choice. With the booming demand for screening solutions in mining, construction, and waste recycling industries, China has become a global hub for high-quality, cost-effective screening machines.

Trommel Screen

Trommel screens are highly versatile, with classifications based on design type, application fields, and customized specifications. As a professional China screening machine factory, Ruijie provides tailored trommel screen and dewatering screen solutions for different industries, matching each application's unique needs.

I. Types of Trommel Screen by Design: Dry & Wet

1. Wet Trommel Screen

Designed specifically for wet, muddy, or sticky materials that are prone to clogging traditional screens. It works with water washing systems to flush away impurities and prevent screen blockage, ensuring continuous and efficient operation.

Commonly used in sand washing plants, mineral processing, sludge de-sliming, and wet scrap metal pretreatment. Ruijie's wet trommel screen features corrosion-resistant materials and adjustable water flow, adapting to various wet material processing needs.

2. Dry Trommel Screen

Suitable for dry, loose materials such as soil, gravel, waste plastics, metal scrap, and dry ore. It requires no water during operation, which not only saves water resources and energy but also reduces environmental pollution.

It is the most widely used type in solid waste sorting, scrap metal pretreatment, and dry mining operations. Ruijie's dry trommel screen has an anti-clogging drum design and adjustable rotation speed, improving screening efficiency and stability.

II. Trommel Screen Applications: Industry, Agriculture & Mining

1. Industrial Application

Widely used in industrial waste treatment, scrap metal recycling, and construction waste sorting. For example, in scrap metal recycling, dry trommel screens sort mixed metal scraps by size; in construction waste treatment, they separate concrete blocks, bricks, and gravel for reuse.

2. Agricultural Application

Applied in agricultural product processing, such as sorting grains, seeds, and agricultural waste. Dry trommel screens can separate impurities (e.g., soil, stones) from grains, while wet trommel screens are used for cleaning and grading wet agricultural materials.

3. Mining Application

A core equipment in mining and aggregate processing. It grades ores, gravel, and sand into multiple specifications in one pass, improving the quality of finished products (e.g., construction sand, ore concentrates). Ruijie's mining trommel screen adopts high-strength steel drums, suitable for heavy-duty work in harsh mining environments.

III. Customizable Screen Holes for Trommel Screens

As a professional China screening machine factory, Ruijie offers customizable screen holes for trommel screens, tailored to the materials being sorted:

- Single-size holes: Used for simple size screening, separating materials into two categories (e.g., large and small metal scraps).

- Multi-specification holes: Realize multi-level grading in one pass, sorting materials into 2-4 different sizes (e.g., gravel grading in aggregate plants).

- Small-size holes: Suitable for removing floating garbage in wet screening, ensuring the purity of target materials (e.g., sand washing and sludge treatment).

IV. Vibrating Dewatering Screen

Vibrating dewatering screen usually equipped with trommel screen.

What is vibrating dewatering screen ?

Vibrating dewatering screen adopts the principle of exciting force, generating high-frequency vibration to separate moisture or sludge from materials. It has a wide range of applications, covering both agricultural and industrial fields.

Application of vibrating dewatering screen

In agriculture, it is used for dewatering agricultural products such as grains, fruits, and vegetables, reducing moisture content to facilitate storage and transportation, and preventing mold growth.

In industry, it is mainly used for impurity removal and dewatering of sand, mineral concentrates, and sludge. For example, in sand and gravel yards, it reduces the moisture content of sand to below 15%, improving sand quality; in wastewater treatment plants, it dewaters sludge to reduce volume and facilitate disposal.

As a reliable China screening machine factory, Ruijie can customize trommel screens (dry/wet, screen holes) and vibrating dewatering screens according to your specific materials, application scenarios, and processing needs. Contact us for a tailored solution and free quote.
