Your simple, rugged and reliable solution to dewatering
Minerals filters must not only provide high through-puts and efficient solids capture, they must operate continuously in harsh environments, handling highly abrasive
materials with minimal attention from operations and maintenance staff. The heavy-duty design of our filter presses has been specially adapted for minerals service with several features designed to enhance their performance in these applications.
What we offer
High throughput, even in harsh environments or with abrasive or corrosive slurries
Our filter presses are designed with recessed or membrane/recess plates to produce minimum cake moisture. Filter plates are available in 1200, 1500, and 2000 mm square sizes.
The AFP IV™ Automated Filter design provides you with a simple, rugged and reliable solution to the special problems associated with solid-liquid separation processes.
These filters not only provide high throughput and efficient solids capture, but they also operate continuously, automatically, in harsh environments, and can handle abrasive or corrosive slurries. When coupled with simple systems and our operating philosophies, your operating costs are maintained at the lowest levels in the industry.
State-of-the-art
filter press technology, including efficient and almost maintenance-free
automatic features, help you achieve rugged and dependable performance for your
individual applications. Our filter presses are
operating in a multitude of conditions around the world, in countries such as
Australia, Brazil, Canada, Kazakhstan, Mexico, Peru, Philippines, South Africa,
United States, Uzbekistan and Zimbabwe.
Key benefits
Easy to operate and maintain
The Automatic Filter Press delivers a range of benefits from fully automatic cake discharge, easy operation and maintenance accessibility to lower maintenance costs and higher performance.
Automated operation
Various levels of automation can be achieved using PLC controller resident in the filter control panel. Customised instrument and control packages are available for integration with existing systems.
Reduced abrasive wear through washing
Thorough washing helps prevent media blinding and reduces abrasive wear on your sealing surfaces. Two wash headers run along the upper edges of the plate stack with nozzles positioned to completely wash every plate face and filter cloth. More advanced systems are also available.
Less time required for plate shifting and cake discharge
To reduce the time you need for plate shifting and cake discharge, our minerals filters utilise a long-stroke cylinder-driven crosshead to open and close the plate stack. More below in features.
Quick media change-out
With filter plates and media support frames designed for unobstructed lift out using a light-duty, overhead crane or lifting frame, you will benefit from fast and efficient change out. Cloths are changed offline while the filter continues to operate. Media cloths attach with a quick release rod and clip arrangement for fast, simple exchange.
Product features
Proven, high-performance design
Some of the key features of the AFP include push closure-cylinders mounted at centerline of press, rolling cross head for plate stacks longer than 50 chambers, automatic cloth washing apparatus, widespread beams and drip trays for liquid containment. Filter media is also available in a variety of materials and weave patterns.
Cloth shaker assists cake discharge
Vibratory discharge assist is provided
by a hydraulically actuated cloth shaker
that transmits a vibration directly to
the filter cloths when one or more
chambers fail to empty completely. To
minimise the effects of vibration on
other system components, the shaker
mechanism is supported on a separate
frame system.
Drip trays prevent rewetting
of discharged cake
Hydraulically operated drip trays
located beneath the filter prevent
filtrate leakage and cloth wash water
from rewetting previously discharged
cake. Both single slope and gable
designs are available.
Cylinder crosshead slashed cycle times
As mentioned, to cut the time you need for plate
shifting and cake discharge, our
mineral filters employ a long-stroke
cylinder-driven crosshead to open and
close the plate stack. Two short-stroke
closing cylinders are mounted in a
rolling carriage, which spans the filter
sidebars. A hydraulically actuated
chain drive or long-stroke cylinder
moves the crosshead and linked
plates quickly between open and
closed positions. With the crosshead
fully retracted, a uniform gap is
opened between each plate, allowing
all chambers to empty. The crosshead
then returns the plates to filtration
position where locking cylinders
anchor the carriage. Closing pressure
is applied to the plate stack and slurry
feed resumed.
All hydraulic operation
Power for plate shifting, crosshead
locking, filter closing, drip tray operation
and cloth shaking is supplied from a single
electrically driven hydraulic power unit. A
filter-mounted manifold contains all
required valves, switches, and gauges for
hydraulic control.
