5. What is the expected productivity per 8 hr. shift?
The productivity shall depend on the speed with which the workmen load grids into the cassette and unload filled plates from the cassette. The min. productivity per eight hour shift shall be in the range of 600 to 800 nos. depending on plate size.
6. How exactly does the dust collector work?
The dust collector works very effectively pulling all dust away from the operators. The dust gets collected on the surface of the filter cartridges and clean air is exhausted out to the atmosphere. The blower fan remains ‘ON’ throughout creating the exhaust draft for the fine lead dust.
The dust collected on the surface of the filter cartridges is dislodged by means of reverse pulse jet of air at regular periodic intervals which is controlled by a timer using diaphragm valve. The dust is collected in a container at the bottom of the hopper. This container should be emptied periodically.
7. What exactly does the differential pressure gauge of dust collector indicate?
The differential pressure gauge indicates the pressure drop across the filter cartridge elements.
This differential pressure is an indicator of the condition of the filter elements. More the differential pressure - more the dust accumulated on the filter cartridge.
This pressure differential must be normally between 100 mm w.c. and 150 mm w.c.. The gauge has a full scale display up to 250 mm w.c. In case the indication exceeds 150 mm w.c. and remains there for long time you must check whether the exhaust flap is fully open. If yes, please close the flap up to 50% or more and check the gauge. In case the gauge indication is not as per recommendations and the suction of dust collector is not efficient / as required - remove the filter cartridges, clean it using compressed air and fit it in place again.
You can also try OFFLINE pulsing i.e. keep the blower ON for about 30 minutes or so after the production of filling has been stopped for the day.
