=='''Design'''== | |||
The | The Filter Dryer designed to separate solids from liquids, it is totally enclosed and is normally operated under pressure or under vacuum. Additionally, the equipment is fitted with a stirrer mechanism which efficiently agitates the slurry during cake washing, smooths and squeezes the cake during filtration and assists in the automatic discharge of the cake. It comprises of a pressure vessel in which a main shaft rotates and also moves in the vertical direction. Specially designed stirrer blades are mounted on the shaft, capable of performing various function. A side discharge arrangement is provided, closing and opening through hydraulic/mechanical means. A filter plate is located at the base of the vessel in level with the discharge port. The filter medium, usually a filter cloth, is fitted on the filter plate which is replaceable type. | ||
