LASTA MC

LASTA MC is a horizontal Filter Press, which has been designed for relatively easy to discharge filter cakes as with Mineral Applications. 

To meet the increasing demands of mining industry slurry dewatering applications, ISHIGAKI, based on years of experience and practical how-how, developed a press to provide high discharge consistency, reliability and performance, coupled with a greatly reduced maintenance requirement.

Features

1. Fully Automatic Operation

LASTA MC is designed for 24 hrs operation, with a Cake Discharge Monitoring System and a Back-Up Mechanism for Fully Automatic Operation. In the event some cakes remain in the chambers, this System activates automatically for perfect Cake Discharge.

2. High Production Capacity

LASTA MC is designed for high production capacity. All functions including Simultaneous Open & Close, Simultaneous Washing and Double-End Feeding Design lead to short cycle time and subsequent high production capability of LASTA MC.

3. Excellent Performance

All filter cloths are washed simultaneously from above the plate pack, leaving no cake residue. 

The efficient cloth wash helps contribute to high and consistent performance of LASTA MC. 

In addition, Cake wash and Air blow are possible due to the Top Feed Port. 

4. Robust and Simple Design

LASTA MC is mechanically simplified and has been designed with fewer moving parts, which leads to easy maintenance even under severe conditions. Especially the filter cloth for each individual chamber can be quickly and easily replaced.

Operation Sequence

Efficient Filter Cloth Wash System

One of the key factors to high press availability and low cloth maintenance lies in the ability to wash the filter cloth efficiently. 

With the cake doors closed and the press open, the stationary shower bars are actuated, washing the exposed cloths. 

The wash water flows down the face of the cloths efficiently cleaning. The shower bars and nozzles are positioned above the chambers to eliminate the potential of clogging from filter cake and do not obstruct filter cloth replacement.

Cloth Support Assembly

The cloths, which are hung from support bars at the top of each plate, can be readilyand individually changed by one person in a few minutes, requiring no skills or tools. 

The support bars are located by springs which are designed to compress under cake load. No adjustments are required during cloth installation.

Discharge Minitoring System and Back-Up Mechanism

If abnormalities in the operating process arise and result in incompletecake discharge after press opening, a photo-electric beam will detect itspresence and a back-up discharge mechanism will be automatically activated. Two vibration rails running the full length of the press are mounted to lifting cylinders. Upon activating the mechanism, the rails are raised coming into contact with the lowered cloth support assembly and its attached cake. 

A vibration force is transmitted to dislodge the filter cake. 

After a preset time the vibrators are turned off and the rails return to their "down" position.
