Coal Screening And Crushing Bucket

1. Multi-Scenario Adaptable Structure

Equipment Compatibility: Can be flexibly mounted on mainstream engineering equipment such as excavators and loaders, without the need for additional power systems. It directly reuses the main hydraulic power source, adapting to the diverse operational equipment needs of coal mines.

Modular Functional Design: Integrates screening, crushing, and mixing as core functions. Through adjustable screen gaps and crushing toothed roller structure, it achieves integrated operation of lump coal grading (0.5mm-300mm) and ultra-large particle coal crushing.

Durable Material Configuration: Adopts a combination of high wear-resistant steel and polyurethane screen plates, optimized for the abrasiveness and high moisture content characteristics of coal (withstanding 21% moisture content), reducing the risk of screen clogging and equipment wear.

2. Intelligent Control System

Parameter Adjustability: Supports precise adjustment of screen angle (15°-25°), vibration frequency (750-1500rpm), and amplitude (4-12mm). Separation parameters are optimized for different coal types such as anthracite and lignite, ensuring a stable screening efficiency of over 92%.

Safety Protection Mechanism: Features a built-in "hydraulic spring integrated balance retraction" system. It automatically retracts and resets when encountering uncrushable materials such as gangue, preventing equipment jamming and damage, and improving the reliability of continuous operation.

1.Efficiency and Precision Advantages:

High Throughput Processing Capacity: A single unit can process 320-680 tons per hour, a 40% increase compared to traditional trommel screens, suitable for the continuous production needs of large coal mines exceeding 500 tph. Low Overcrushing Rate: Utilizing selective crushing technology, only oversized coal particles are instantly split, while qualified coal particles are directly screened through, reducing fine powder production by 35% and improving coal utilization.

Precise Grading: Employing a dual-motion vibration mode (linear + elliptical vibration), a separation accuracy of over 95% is achieved, meeting the stringent requirements of circulating fluidized bed boilers for coal particle size (6-50mm).

2. Economic and Environmental Value:

Significant Cost Reduction and Efficiency Improvement: Compared to the traditional combination of crushing and screening equipment, investment costs are reduced by 40%, labor requirements by 60%, and energy consumption is only 1.2 kW·h/t, 30% lower than the industry average.

Controllable Maintenance Costs: The modular screen design allows for rapid replacement within 45 minutes (87.5% shorter than the industry standard), extending the service life of vulnerable parts to 18 months, reducing annual maintenance costs by 22%, and compressing the investment payback period to 14-17 months.

Low-carbon operation characteristics: Operating noise is controlled below 75dB, reducing dust spillage and equipment exhaust emissions, meeting the green production standards for coal mines.

3. Flexibility and adaptability

Strong site adaptability: No fixed installation foundation is required; it can operate in multiple scenarios such as underground mining faces and surface coal washing plants, especially suitable for the decentralized processing needs of small and medium-sized coal mines.

Multi-condition compatibility: It can achieve dry separation of lump coal and coal powder, and can also participate in wet screening as part of coal washing machinery. It is also compatible with auxiliary processes such as coal slime dewatering and tailings recovery.

1. Coal mine front-end processing

Raw coal grading and screening: Raw coal is directly graded by particle size at the mining site. Qualified lump coal is directly transported to the coal storage yard, and oversized coal is crushed on-site before screening, reducing ineffective transportation costs.

2. Coal Slurry Treatment and Recycling: For high-moisture coal slurry produced by coal washing plants, solid-liquid separation is achieved through high-frequency vibrating screening. The recovered coal powder has a moisture content reduced to below 15%, allowing it to be directly mixed into marketable coal for sale.

3. Coal Pretreatment

Power Plant Coal Preparation: Customized screening and crushing services are provided for circulating fluidized bed boilers to ensure uniform coal particle size, reduce boiler dust emissions and energy consumption. After application in one project, coal utilization increased by 17%.

Coal Chemical Raw Material Purification: Precise grading of coal for gasification removes fine powder and gangue impurities, improving raw material purity and reducing the risk of slagging in the gasifier.

4. Environmental Protection and Recycling Fields

Coal Gangue Separation: Gangue is simultaneously screened and removed during coal mining, reducing the load on subsequent washing and beneficiation processes. The separated gangue can be directly used for roadbed filling, realizing the resource utilization of solid waste.

Contaminated Soil Remediation: In coal gangue dump remediation projects, the mixture of contaminated soil and coal gangue is screened and crushed to achieve separation and treatment of soil and pollutants.
