|LASTA mineral concentrate filter press|
To remain cost effective today, a mine's daily filtration tonnage requirement needs to be met with fewer machines, providing high filter cake volumes, without operator intervention or frequent maintenance requirements.
Open & Close Time - 4 minutes
Filtration - 4 minutes
Cake Air Blow - 2 minutes
Polypropylene filter plates are designed for high flow top center feed. Concentrate is delivered from both ends. Filtrate discharges through large filtrate ports.
Cake air blow is via the filtrate manifold, delivered to the chambers via high wear replaceable filtrate port.
Cake Discharge - less than 1 minute
Cake discharge is fully automatic. The design of the filter chamber and separation of the cloth from the plate actuates discharge, any momentarily held cakes are dislodged by the cloth drop mechanism. Sticking cakes are sensed by the cloth hanger bar resting on the vibrator tube. This condition actuates a vibration frequency designed to discharge all remaining cakes.
Cloth Washing - 1 minute
Cloth washing is application specific and may be set for a total cloth wash:
•After each cake discharge cycle
•Rotating batches of cloth
•After a specific number of cycles for water conservation
A unique feed device, attached to the filter cloth provides excellent concentrate delivery into the chamber and a protective rubber layer is used to ensure a high number of cycles before filter cloths require changing.
This protection allows many more options for filter cloth designs to be selected.
The filter press can be configured with either recessed filter plates or combination membrane / companion recessed plates.
Membrane squeeze plates provide the option for squeezing at high pressure and can be used to shorten the cycle time and/or consolidate the filter cake for more effective air blow results.
In the case of membrane plates, additional equipment is required to provide high pressure water for squeezing.
Service and Testing
A critical component of any filter press application is after service. Without support when necessary, sophisticated equipment can become both expensive to maintain and unreliable.
With our support the LASTA-MC will remain as designed - efficient, cost effective, and highly reliable. Both Ishigaki Company LTD., and Micronics have partnered to provide spare parts, service and application assistance.
