Built to the Highest Standards
Designed and manufactured under the strictest ISO 9001:2008 quality management system, filter presses from Evoqua provide solutions specifically for your unique mining application. Whether you require higher solids throughput for mineral concentrates, tailings, or a high rate filtration application, we have a high performance filter press in our portfolio for you.
Higher Throughput from Faster, Automated Cycles
With a mineral concentrate press cycle of 8–12 minutes depending on the model and number of plates, the MC Press® filter press provides an exceptionally high throughput rate. Feed times typically range from 1.5–2.5 minutes, with filter plates linked together accordion-style for rapid cake discharge. These efficiencies allow the press to complete as many as 150 cycles per day without interruption. The MC Press filter press also benefits from a complete automation and instrumentation package, eliminating the need for an operator. A feed flow meter and pressure transmitter indicate press fill completion, and load cells determine the solids production rate while controlling moisture during cake air blow.
Backup Cake Discharge Mechanism
The MC Press filter press employs a dual system to ensure discharge of all dewatered filter cakes. Filter cloths suspended by spring-supported bars are pulled down by the weight of the filter cake, stopping suddenly at the end of their travel, and shearing the cake from the cloths. The springs then return the bars to their normal raised position. Should the cakes fail to discharge, the cloth support bar remains in the lowered position. After a photo-eye verification of the discrepancy, a vibration bar engages it to ensure complete filter cake discharge. If the cloth support bar continues to remain in the lowered position, the press cycle stops and an alarm sounds, ensuring the press does not operate with cakes remaining in their filter chambers. As a critical step to ensure maximum cloth life and proper press sealing, a cloth wash system removes all remaining solids after each cake discharge cycle.
Three Frame Designs to Match Your Capacity Requirements
The MC Press® filter press is available in three unique frame designs, with plate sizes of 1.5 m x 1.5 m and 1.5 m x 2.0 m. All are available in a range of cake thickness and operating pressures to meet a wide variety of applications and production requirements. Each press can be further customized with either recessed chamber or membrane squeeze plates depending on your individual needs.
The H model incorporates a single, long stroke, hydraulic cylinder to close and clamp the plate stack and move the plates for cake discharge. Plates are linked together, allowing the filter cakes to discharge simultaneously as the press is pulled open by the hydraulic cylinder. The H model is available with up to 50 filter chambers for a throughput capacity of up to 65 tonnes/hour on a typical mineral concentrate.
The S model incorporates four short stroke hydraulic cylinders to clamp the plate stack and a plate traveler mechanism to retract the follower. Plates are moved by a mechanical chain drive system and are linked together, allowing the filter cakes to discharge as the press is pulled open by the drive assembly. The S model is available with up to 64 filter chambers for a throughput capacity of up to 90 tonnes/hour on a typical mineral concentrate.
Ideal for larger operations, the D model incorporates many of the same features as the S model, with four short stroke hydraulic cylinders, a mechanical drive system for cake discharge, and linked plates. Both ends of the D model press move simultaneously, further increasing efficiency by speeding cake discharge. The D model is available with up to 130 filter chambers for a throughput capacity of up to 170 tonnes/hour on a typical mineral concentrate.
