Full Function Filter Press Equipment

Backed by 16+ years of experience, expert knowledge and continuous improvements, we deliver optimal filtration outcomes for diverse applications.

Filtration Equipment for Diverse Applications

The ENPROTEC full-function filter press is designed to achieve the best results in mining and mineral slurry dewatering. All ENPROTEC filter presses offer full functionality, including automatic opening and membrane squeeze. This is made possible by our machines’ highly specialised innovation and design, as well as the use of the highest-quality engineered components. Our filter technology is applied in various industries, the most important of which is the dewatering of multiple minerals in concentrates and tailings. We also specialise in Mobile Filtration Units.

Feeding Philosophy

ENPROTEC has developed and employs a highly specialised filter feeding philosophy which optimises the feeding and filtration step of the filtration cycle. Making use of flow and pressure control, this philosophy achieves “flash fill” of the chambers, minimising feeding times and maximising solids recovery through the instantaneous creation of a secondary filtration boundary layer (feed material solids) against the filter cloths. This feeding philosophy is fully automated and is controlled by the PLC (Plant Logic Controllers).

Simplified Material Handling

Achieving consistent minimum moisture filter cakes is crucial for material handling within the filtration facility as well as for downstream processes. Dry and competent filter cakes enable guaranteed cake release from the filter press and eliminate downstream blockages of conveyor transfer points and bulk material handling machinery. Additionally, ENPROTEC has developed a PCR (Positive Cake Release) system for highly tenacious sticky cake applications, effectively eliminating the risk of cake holdup during the press opening step of the filtration cycle.

Effective Liquid-Solid Separation

This double layer filtration process, filter cloth as well as the formed feed material packed bed layer, ensures the highest possible material recovery as well as solids free filtrate. Directly returning this filtrate to the upstream processes greatly reduces make up water requirements through achieving a closed loop water system.

Broad Commodity Spectrum

Our solutions have been developed across most minerals and materials, such as Lithium, Zinc, Copper, Coal, Heavy Mineral Sands, Gold, Vanadium, Iron Ore, Rare Earth Minerals, to name a few.

Consistent Minimal Moistures

Through the application of ENPROTEC’s innovative filtration systems such as the feeding control philosophy, membrane squeeze and cake blow, the lowest mechanically achievable filter cake moistures are ensured, cycle after cycle, irrespective of fluctuating feed material characteristics.

Local Technical Support

Our local technical team exemplifies reliability and precision across all aspects of equipment support, ensuring uninterrupted operations and maximising availability.

Technically Engineered

Filtration Rate

The filtration rate is determined by the filter media’s permeability, the pressure applied, and the slurry characteristics. At ENPROTEC, we optimise filtration rates by operating our presses at controlled pressures and flows and using filter cloths with appropriate aperture sizes.

Plate Design and Material

ENPROTEC utilises filter plates made from high-quality virgin polypropylene. Polypropylene plates are lightweight and resistant to chemical corrosion, suitable for a wide range of applications. Our plates are durable and ideal for various temperature and pressure processes. Through our specialised plate designs, which include recessed and membrane plates, to ensure optimal filtration efficiency and cake dryness.

Automation and Control Systems

Our modern filter presses at ENPROTEC are equipped with PLC (Programmable Logic Controller) systems that automate the entire filtration cycle, from filling to pressing and cake discharge. Advanced control systems monitor real-time parameters such as pressure, flow rate, and cycle time, adjusting the process to optimise performance. Features like automatic cloth washing, plate shifting, and remote monitoring enhance operational efficiency and reduce manual intervention.

Cake Discharge Mechanism

Efficient cake discharge mechanisms are essential for minimising downtime and ensuring continuous operation. ENPROTEC’s filter presses incorporate automatic plate shifters, which sequentially separate the plates to release the filter cake with positive cake release systems that aid in cake detachment. The choice of mechanism depends on the nature of the filtered material and the required level of automation, ensuring reliability and efficiency.
