Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] Such as image 3 As shown, the invention provides a kind of preparation method of high-efficiency coagulation accelerator, comprises the steps:

[0060] Step 100, setting an abrasive mechanism between the desulfurized gypsum one-step drying mechanism and the two-step calcination mechanism;

[0061] Step 200, when the preparation raw material in the abrasive mechanism is insufficient, lower the drying temperature of the one-step drying mechanism from th...

Abstract

The invention discloses a preparation method and system of an efficient coagulant. The system comprises a drying mechanism which is provided with a first discharge hole and a second discharge hole; a calcining mechanism which is connected with the first discharge hole; and a grinding mechanism which is connected with the second discharge hole of the drying mechanism, and is used for grinding the dried desulfurized gypsum to obtain a coagulant finished product. The drying mechanism is internally provided with a first cavity and a second cavity, the first cavity and the second cavity are used for forming different drying temperature areas, the first cavity and the second cavity are controlled to be communicated or not communicated through an intercommunication piece, the first discharge hole is connected with the first cavity, and the second discharge hole is connected with the second cavity. The method and system can be directly applied to a two-step calcined gypsum board production factory, the raw material for preparing the coagulant of the grinding mechanism directly uses the desulfurized gypsum one-step clinker, there are no impurities such as waste paper pieces, and the purity of the raw material is high.

Description

technical field [0001] The invention relates to the technical field of gypsum board production, in particular to a preparation method and system of a high-efficiency coagulant accelerator. Background technique [0002] The coagulant for gypsum board generally uses dry dihydrate gypsum with a taste of more than 80% as raw material. This dihydrate gypsum mainly accelerates the coagulation of gypsum by increasing the number of crystal nuclei in the gypsum slurry. [0003] With the expansion of the demand for gypsum board, the production capacity of the corresponding gypsum board production line continues to expand. In the process of increasing the speed of gypsum board production, the amount of coagulant is continuously increased. At present, the raw materials used for the preparation of coagulant are mainly waste gypsum board. Corner dust collection powder, etc., the production process is offline, the raw materials need to be ground with powder and ink tools, and then added to...
