Un-sufficient cake dewatering.
1. Too short de-watering timer.
2. Cake thickness below 2cm.
3. Too thin slurry.
4. Liquid outlet is lower than the level in the solution tank and without
check valve.
5. The chemical is not suitable for this machine.
6. Viscous slurry is not suitable for this machine (dry up by air).
Prior to semi-automatic running.
1. When the machine is running in automatic mode, you can press auto
stop button(Control panel #8) to shift to semi-aotomatic mode.
2. The semi-automatic mode will run single cycle and stop. It’s feeding,
de-watering, moving plate down, moving cake out.
3. Precipitation tank before the de-watering machine is recommended to
speed up the de-watering.
Capacity
With precipitation tank: 30% liquid, 70% sludge, 20~25Kg for each 10
minutes.
Without precipitation tank: 70% liquid, 30% sludge, 15~20Kg for each 15
minutes.
Slurry of higher specific gravity will slow down the capacity.
Slurry with coagulant is not suitable for this machine.
