EFFICIENT WET STARCH PREPARATION SYSTEM FOR GYPSUM BOARD PRODUCTION

摘要

It include starch gypsum wallboard loss in weight feeder the present invention provides a kind of wet starch preparation system, venturi mixer, vacuum pickup unit, which is used to from feeder supply water dried starch with adj sp to venturi mixer, the first water pump, forms the starch and the second water pump of from about 2% to the about 10% weight % of predispersion of starch with adj sp to venturi mixer, for providing gauging water and starch pre-dispersion, system is controlled equipped with system appropriate. It is at least about 10% less than system that this system, which provides the pregelatinized starch for more effectively using starch to make the amount, do not make wherein starch in water before pre-dispersed plate mixer., the system can be used for manufacturing gypsum-containing products, including there is gypsum wallboard plate intensity to increase and plate weight.
