Brief introduction:
In industries such as chemicals, mining, and minerals processing, process conditions are often extremely challenging. Facing high-concentration, high-viscosity, or highly corrosive materials, reliable dewatering and product recovery are directly critical to maintaining continuous and efficient production. Addressing this industry pain point, TONCIN has leveraged decades of technical expertise in horizontal vacuum belt filter (DU) technology to deliver a filtration solution that combines high throughput capacity with low residual cake moisture, while effectively controlling operating costs and helping customers achieve both economic efficiency and production stability.
Product Description
A Cost-Effective Solution for Dewatering and Product Recovery
TONCIN horizontal vacuum belt filters offer multiple advantages for process plants:
High-Throughput Dewatering and Cake Washing: Outstanding processing capacity per unit area, suitable for large-scale continuous production.
Reduced Downtime Due to Innovative Design: Optimized critical structures enable convenient maintenance and ensure long-term stable operation.
Global Testing Facilities: Leveraging comprehensive testing platforms to validate process parameters in advance and reduce project risks.
Increased Flexibility Due to Modular Design: Flexible configuration based on site conditions and process requirements, offering strong adaptability.
High-Throughput Dewatering and Cake Washing Application Example
A horizontal vacuum belt filter with a filtration area of 20 square meters has been successfully applied in a graphite concentrate dewatering project, demonstrating exceptional high-throughput processing capability and stable cake washing performance.
Engineering Solutions for Optimized Designs
TONCIN possesses fully integrated engineering capabilities, utilizing advanced engineering tools to achieve precise design and ensure optimized equipment sizing and footprint. Key engineering capabilities include:
CFD Analysis
3D Modeling
FEA Analysis
Additionally, a wide variety of construction materials combined with a bolted frame structure enable modular customization according to specific customer requirements, balancing strength, corrosion resistance, and installation convenience.
Washing Applications: High Extraction Efficiency Driving Profitability
In washing processes for materials such as gold, uranium, phosphoric acid, copper, and alumina, extraction efficiency directly impacts project profitability. TONCIN horizontal vacuum belt filters utilize plug flow displacement and multi-stage counter-current washing across the filtration area to achieve wash efficiencies exceeding 99.8%, providing reliable support for efficient recovery of high-value materials.
Materials of Construction: Designed for Demanding Conditions
For complex operating conditions involving corrosive, abrasive, and high-temperature filtration applications, TONCIN offers a full range of material solutions—from high-quality stainless steels to FRPs and plastics. The filter frames are manufactured using open channel and angle sections, effectively avoiding the liquid accumulation and corrosion issues commonly associated with box-section structures in corrosive environments, thereby significantly extending equipment service life.
Cake Discharge and Transporter Belt
In most applications, cake discharge occurs spontaneously by gravity. For wet, sticky products, TONCIN can equip the filter with cake scrapers or water slides to ensure complete cake removal and prevent material buildup that could affect operational efficiency. TONCIN has successfully manufactured extra-wide filters utilizing 4.8-meter rubber belts, with belt materials selected from natural rubber, SBR, neoprene, or EPDM based on process requirements. All TONCIN transporter belts feature a carcass-free center zone design, preventing contact between the filtrate and the belt carcass, effectively resisting corrosion and significantly extending belt service life.

Innovative Technology: Vacuum Box Lifting Device
To further enhance equipment performance and maintenance convenience, TONCIN has developed the vacuum box lifting device. This device simplifies the traditionally high-risk task of vacuum box maintenance and can be retrofitted to filters of any brand or size, reducing vacuum box maintenance downtime by over 30%.
Dual Cloth Tensioning System
TONCIN filters are designed with a dual cloth tensioning system, incorporating both static and dynamic tensioning. This system maintains efficient operation even if the filter cloth experiences abnormal stretching, while the use of movable rollers significantly simplifies filter cloth installation and replacement, reducing maintenance complexity.
