Henan San Kuang Machinery Technology Co., Ltd. introduces our latest high-performance High-Capacity Mining Centrifugal Dewaterer, engineered specifically for coal slime dewatering with a processing capacity of up to 50 tons per hour. With over a decade of manufacturing expertise since 2014 and a factory spanning 10,000–30,000 square meters, we deliver robust solutions that reduce moisture content effectively, enhance solid-liquid separation, and minimize operational costs. Our centrifugal dewaterer combines advanced mechanical design with intelligent control, ensuring reliable operation in harsh mining environments.
This equipment is designed to handle fine coal slime (typically 15%–20%, depending on feed characteristics. It utilizes a rotating drum and screw conveyor to generate high G-force, forcing water out through a screen while solids are discharged continuously. Key components are manufactured from abrasion-resistant materials, extending service life and reducing maintenance frequency.
Key Features & Technical Advantages
- High Capacity: Up to 50 t/h feed rate, ideal for large-scale coal preparation plants.
- Low Moisture Content: Achieves 15%–20% final moisture in coal slime, improving thermal value and reducing drying costs.
- Heavy-Duty Construction: Drum and scroll made of wear-resistant alloy steel, lined with ceramic tiles for extreme durability.
- Automated Operation: PLC-controlled system with touch screen interface, real-time monitoring of speed, torque, and vibration.
- Energy Efficient: Variable frequency drive (VFD) adjusts speed based on load, saving up to 20% power compared to fixed-speed models.
- Easy Maintenance: Quick-open access covers and replaceable screen panels reduce downtime.
- Customizable: Available with different screen gaps (0.25–0.5 mm), motor options, and base frames to suit specific site requirements.

Frequently Asked Questions
-
Q: What type of coal slime can this machine handle?
A: It is designed for fine coal slime with particle size typically less than 0.5 mm, including flotation concentrates, tailings, and other fine coal slurries. For coarser materials, we recommend our screen scroll centrifuge series. -
Q: What is the expected moisture content after dewatering?
A: Under normal conditions, the final moisture content ranges from 15% to 20%, depending on feed solid content and particle size distribution. We can provide a laboratory test to estimate performance for your specific material. -
Q: How long does it take to install and commission?
A: Typical installation takes 5–10 working days with our on-site supervision. Commissioning and operator training are included in the service package. -
Q: What maintenance is required?
A: Routine maintenance includes checking bearing lubrication, screen condition, and belt tension every 500 operating hours. The machine is designed for easy access to all wear parts. -
Q: Can the capacity be adjusted for different throughput requirements?
A: Yes, the VFD allows speed adjustment to match feed rate. We also offer different drum sizes and motor powers to meet your specific capacity needs within the 50 t/h range. -
Q: Does the machine come with a control panel?
A: Yes, each unit includes a PLC-based control panel with HMI touchscreen, providing real-time data on speed, torque, temperature, and vibration alarms. -
Q: What spare parts do you recommend keeping in stock?
A: We suggest keeping a set of screen panels, a set of sealing rings, and a spare bearing cartridge. A complete list is included in the operation manual. -
Q: Is pre-sales testing available?
A: Absolutely. We can arrange a small-scale pilot test using your coal slime sample at our factory or provide a rental unit for on-site trials.
