HDC Series – Centrifugal Wet Dust Collector

Manual Sludge Removal

This arrangement uses a flat-bottom hopper designed for periodic manual sludge removal. It is suitable for applications with light dust loading or non-continuous operation where sludge accumulation remains limited.

The structure provides maintenance access doors and sufficient internal clearance to allow safe and convenient cleaning. This solution offers a simple mechanical design, reduced equipment height, and lower initial investment compared with automated discharge systems.

Typical applications

• Light dust collection systems
• Metal polishing and finishing exhaust
• Packaging and weighing stations
• Chemical process ventilation

Scraper Sludge Removal

This arrangement uses a drag-chain scraper system to automatically remove sludge from the hopper while allowing effective dewatering during discharge. It is designed for moderate to heavy dust loads and continuous industrial operation.

A geared motor drives a wear-resistant chain and sprocket assembly to ensure reliable performance. The steep hopper geometry minimizes material build-up, while the slow scraper movement improves sludge dewatering and helps reduce fresh water consumption.

Typical applications

• Continuous production processes
• Foundry and abrasive treatment systems
• Grinding and surface preparation lines
• Bulk material handling systems

Hydraulic Sluicing Discharge

This arrangement uses a pyramid hopper combined with a hydraulic flushing system to transport sludge continuously or intermittently to a designated discharge point. It is suitable for applications requiring minimal manual intervention.

The system maintains proper water level through controlled make-up water and drainage. This design enables stable long-term operation and is particularly suitable where continuous sludge evacuation is required.

Typical applications

• Mining crushing and screening plants
• Chemical processing facilities
• Conveyor transfer point dust control
• High dust load process exhaust systems

Hydrogen Safety Monitoring

For applications involving light metal processing such as aluminum, magnesium, or titanium, the HDC series can be equipped with a hydrogen safety monitoring package. This includes a hydrogen concentration sensor and an automatic venting device mounted on the collector top. The system continuously monitors gas levels and automatically releases accumulated hydrogen when the fan stops, reducing explosion risks and improving operational safety.
