Preparation device using waste plasterboard for preparing coagulation accelerating agent

Abstract

The invention discloses a preparation device using a waste plasterboard for preparing a coagulation accelerating agent. The preparation device comprises a whirlwind dust collecting and power selectingsystem and a ball mill system, an airflow whirl mill is connected to an input end of the whirlwind dust collecting and power selecting system and used for performing millstone treatment on plaster particles, the whirlwind dust collecting power selecting system discharges the plaster particles after the millstone treatment according to the differences of the grain sizes, the ball mill system is used for performing machining treatment on the separated plaster particles, and a feeding hopper is connected to an input end of the airflow whirl mill. A two-step method is adopted for preparing the coagulation accelerating agent, the coagulation accelerating agent with the grain sizes being relatively uniform can be prepared, the superior coagulation accelerating effect can be achieved, and the quality and the production efficiency of the coagulation accelerating agent are improved.

Description

technical field [0001] The invention relates to the technical field of gypsum board production, in particular to a preparation device for preparing coagulant by using waste gypsum board. Background technique [0002] The current preparation process of the coagulant is to put the scrapped gypsum board into the ball mill to make the coagulant after being crushed by the crusher, because there are a lot of face-protecting paper dust in the crushed gypsum particles, which will reduce the production efficiency of the ball mill , and the prepared coagulant contains a large amount of paper pieces, resulting in uneven particle size distribution of the coagulant, resulting in unsatisfactory coagulation effect. With the expansion of the gypsum board market, the production capacity of gypsum board needs to be increased urgently. In this case, the production speed must be increased to obtain greater production capacity. The setting time is a key indicator that limits the increase in prod...
