Drum-Type Screening Machine

Product Overview

The drum-type screening machine is a device specially designed for grading and screening materials across multiple industries. It features an optimized anti-clogging structure particularly suited for household waste and moist, easily clogging materials, achieving a screening efficiency of over 90%. The equipment mainly consists of a transmission system, a cylindrical drum, a frame, a protective cover, and inlet and outlet openings. By rotating the inclined drum, the material is turned and rolled, enabling precise separation of materials according to different specifications. At the same time, it can effectively eject materials stuck in the screen holes, reducing the screen blockage rate by 80%, with a failure rate of less than 5%. The machine operates smoothly with low noise, and its fully enclosed design effectively prevents dust, making it suitable for various applications such as waste treatment, organic fertilizer production, building material processing, and mining operations.

Working Principle

The core working logic of the drum-type screening machine relies on the rotation of an inclined drum: the drum continuously rotates at a set speed, and after materials enter through the inlet, they are constantly turned and rolled along with the drum’s rotation, moving downward under gravity. During this process, materials that meet the screen hole specifications pass through the holes and fall into the lower collection area, while those that do not continue toward the outlet, completing the grading and screening process. Meanwhile, the continuous tumbling and rolling action inside the drum promptly ejects any material lodged in the screen holes, fundamentally preventing blockages and thoroughly solving the industry challenge of clogging encountered when using circular vibratory screens or linear screens to handle moist materials, thus ensuring the equipment’s sustained and stable operation.

Core Performance Advantages

1. Anti-Clogging Design: Leveraging the tumbling and rolling motion of materials within the drum, it automatically ejects debris trapped in the screen holes, reducing the screen blockage rate by 80%. This makes it especially suitable for screening moist, easily clogging materials without frequent shutdowns for cleaning.
2. High Screening Efficiency: With a screening efficiency exceeding 90%, it quickly processes large volumes of materials, boosting overall production efficiency and reducing material accumulation and waiting times.
3. Low Failure Rate and High Reliability: Featuring a simple structure and stable core component design, the equipment has a failure rate of less than 5%, low daily maintenance costs, and can operate continuously for extended periods, ensuring seamless production flow.
4. Environmentally Friendly and Quiet Operation: Equipped with a fully enclosed dust-proof cover, it effectively prevents dust dispersion during screening, while operating smoothly with low noise, creating a more environmentally friendly and user-friendly working environment.
5. Flexible Adaptability: The screen mesh is replaceable, allowing adjustment of mesh size based on specific material requirements, and customizations are available for external dimensions and the transmission system, accommodating diverse job sites and production process needs.

Applicable Material Range

This equipment can efficiently screen a wide variety of materials, including household waste, moist and easily clogging materials, sand and gravel aggregates, wood chips, organic fertilizer granules, and more. Whether it’s high-moisture kitchen waste, highly viscous organic fertilizer raw materials, or hard rock and gravel from mines, this machine can perform efficient grading and screening, meeting the material-handling needs of different industries.

Target Customer Groups

Waste treatment plants: Used for sorting household waste, enabling preliminary separation of recyclables, food waste, and other types of garbage, thereby improving overall waste management efficiency; Organic fertilizer producers: Screen both raw materials and finished granular products to ensure uniform product specifications; Building material companies: Grade sand and gravel aggregates to meet the varying raw material requirements of different construction products; Mining enterprises: Screen mined ores and tailings to enhance resource utilization.

Typical Application Scenarios

1. Household Waste Sorting: In waste treatment facilities, mixed household waste is screened to separate items of different sizes and types, providing pre-processing support for subsequent incineration, landfilling, recycling, and other processes;
2. Organic Fertilizer Granule Screening: During organic fertilizer production, fermented raw materials are screened to select qualified finished granules, while larger unfermented chunks are separated for secondary processing;
3. Sand and Gravel Aggregate Grading: In building material processing or mining operations, excavated and crushed sand and gravel aggregates are graded to obtain products of varying particle sizes, tailored to the raw material needs of concrete, road base construction, and other applications;
4. Wood Chip Screening: In wood processing or biomass energy production, wood chip raw materials are screened to obtain uniformly sized chips, ensuring stability for subsequent processing or combustion.

Solving Industry Pain Points

1. Clogging During Moist Material Screening: Traditional screening equipment often suffers from severe screen blockages when handling moist materials, leading to sharp drops in screening efficiency and even necessitating shutdowns for cleaning. The drum-type screening machine’s anti-clogging design reduces screen blockage rates by 80%, eliminating the need for frequent stoppages and ensuring uninterrupted operations;
2. Low Screening Efficiency: Conventional screening machines tend to experience material buildup and incomplete screening when processing large quantities, whereas this equipment achieves over 90% screening efficiency, rapidly completing material grading and boosting production efficiency;
3. Dust Pollution: Open-style screening equipment generates substantial dust, contaminating the work environment and posing health risks to operators. This machine employs a fully enclosed dust-proof cover, effectively containing dust dispersion and complying with environmental standards;
4. Screen Mesh Wear: Some screening equipment features poorly designed mesh structures that wear out quickly when processing hard materials. This machine’s replaceable mesh and drum-based design minimize direct impact between materials and the screen, extending mesh life and reducing maintenance costs.

5. Applicable Materials: Household waste, moist and easily clogging materials, sand and gravel, wood chips, organic fertilizers, etc.

Frequently Asked Questions (FAQ)

Q1: What advantages does the drum-type screening machine have over a circular vibratory screen?
A: The drum-type screening machine features an anti-clogging design—materials tumbling and rolling inside the drum automatically eject debris stuck in the screen holes, reducing the screen blockage rate by 80%. It is particularly well-suited for screening moist materials, whereas circular vibratory screens often become severely clogged when handling moisture, requiring frequent cleaning. Additionally, this machine operates more smoothly with lower noise levels, and its fully enclosed dust-proof design is more environmentally friendly.
Q2: What types of materials can this equipment process?
A: It can handle various household wastes, moist and easily clogging materials, sand and gravel aggregates, wood chips, organic fertilizer granules, and more, making it suitable for waste treatment, organic fertilizer production, building material processing, mining operations, and other industries.
Q3: Can the screen mesh be replaced?
A: Yes, the mesh can be swapped out to suit different material specifications, and users can also customize the external dimensions and transmission system to fit their specific operational needs.
Q4: What is the equipment’s failure rate?
A: With its simple structure and stable core component design, the equipment boasts a failure rate of less than 5%, low daily maintenance costs, and the ability to operate continuously for long periods, ensuring smooth and consistent production processes.
