LASTA MC Filter Press

LASTA MC ‐ Typical Flow

LASTA MC – Process Mechanism Feed slurry 6. Cloth Washing 1. Plate Closing 2. Slurry Feeding Compressed water 3. Compression 5. Cake Discharge 4. Plate Opening

LASTA MC ‐ Mechanism 1. Press Close 2. Feeding 3. Compression Feed slurry Pressurized water All filter plates are closed Slurry is fed from the top feed Pressurized water (air) is injected simultaneously by Plate channel into each filter chamber, into the inside of diaphragm. the Travel motor and clamped filtered by two filter cloth and filter cake is further compressed by hydraulic cylinders. then formed the filter cake. and dewatered. compressed air is Once the plates are clamped Filtrate is discharge out from the applied for less than 0.7MPa together, slurry feed channel filtrate chute positioned on the compression. Higher compression is formed at the top of plates. bottom core of each plates. applies to compressed water. (Top Feeding)

LASTA MC ‐ Mechanism 4. Plate Opening 5. Cake Discharge 6. Cloth Washing After compression process, At the same time with press After cake discharge process dripping pan is opened and open, dewatered cake is is completed, dripping pan is hydraulic cylinder is clamped discharge out of each closed and then all filter cloth off and all plates are opened chamber simultaneously. are washed simultaneously simultaneously by Plate Undischarged cakes are by spray nozzles positioned Travel system. monitored and forcibly at the center and both sides discharged with vibration of the cloth support bar. mechanism.

LASTA MC ‐ Mechanism (option) Cake Wash Back Wash Air Blow In order to remove unnecessary dissolved substance from the cake or Compressed air is fed into extract the dissolved precious materials as filtrate, Cake Wash the chamber from one side of Process is applied as option. The wash water penetrate and replace filtrate channel and blow out the dissolved substance in the cake with wash water. Replaced liquid the remained filtrate out of is discharged out as filtrate. filter cake.

LASTA MC ‐ Advantages 1 Simultaneous All Chambers Open & Close System All filter chambers simultaneously opened and closed by Plate Traveling System, which make possible to discharge the cake simultaneously and shorten process cycle time. It results in higher production capacity than conventional Filter Press.

LASTA MC ‐ Advantages 2 Cake Discharge monitoring system with back-up Mechanism Undischarged cake is monitored by cloth support bar position detective sensor and then forcibly discharged by cloth vibration mechanism, which result in no need labors for cake discharge.

LASTA MC ‐ Advantages 3 Simple Structure, Easy Maintenance The main maintenance work for Filter Cloth is replacement of filter clothes. LASTA MC makes possible to replace the filter cloth very easily and quickly due to its simple structure. Filter cloth replacement time shall be a min per chamber, which shortens down time and save labors cost.

LASTA MC ‐ Advantages 4 Efficient Filter Cloth Wash System In every cycle, all Filter Cloths are washed simultaneously by the spray nozzles mounted on the cloth support bars, which doesn’t leave the cake residue. The efficient cloth wash contribute to high and consistent performance of LASTA MC. Robust and Simple Design for 24hrs fully automatic operation LASTA MC is mechanically simplified and designed with robust and less moving parts, which leas to 24hours fully automatic operation under severe operating conditions.
