What’re the storage and feed system of cements of concrete batching plant?
This system of concrete batching plant includes a cement bin and a screw conveyor. The cements are transported from the screw conveyor to the weighing hopper for weighing.
a) Cement bin
It’s a cylindrical steel structure with maximum capacity of100 tons of cements.
An arch-flushing device is mounted on the bottom cone of the bin, which is controlled by an air valve. The device is used to blow out the possible cement arch with an “air cushion” to ensure a stable discharge of material.
A strain type level meter is mounted on the cement bin, through which the level inside the bin can be accurately displayed in the operator’s room. The dust collector is on the top of the bin, which removes the dust caused by flushing of cement “arch” and pumping of cement so as to meet the environmental standards.
The feeding port is about 14m high above the ground level. The cements are fed through air compressor to the bin.
b) Screw conveyor
It is installed between the cement bin and weighing device for cements. Cements are transported from the feeding port to the weighing hopper by a thrust force of the blade caused by rotating of the screw driven by a gearbox with a 11KW motor..
(4) Water supply system
This system is composed of a water pump, a one-way valve, and a manual valve.
A water tank or water pool is to be chosen by users on the basis of different situations.
