A device for improving clinker phase composition during ball milling

Abstract

The embodiment of the invention discloses a device for improving the phase composition of clinker in the ball milling process, including: a moisture discharge chimney connected in sequence, an induced draft fan, a hollow cylindrical reamer and a ball mill body, and a rotary joint and a rotary air jet , the air inlet of the rotary joint is connected to the air outlet duct of the induced draft fan, the right end of the rotary joint is slidably connected with a central rotating shaft located at the inner axial end of the hollow cylinder reamer, and the central rotating shaft The outer wall is set as a hollow structure, and the outer surface of the central rotating shaft is also fixedly connected with a spiral hinge, and the right end of the hollow cylindrical reamer is connected to the rotating air jet port, and the rotating air jet port is arranged inside the ball mill body. The upper outer wall of the hollow cylindrical reamer is provided with a feed inlet, the whole device not only reduces the content of anhydrite A3 in the plaster, but also reduces the water-to-plaster ratio in the production of gypsum boards, thereby reducing energy consumption, It plays a role in improving the bonding and strength of the board.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of gypsum board production, in particular to a device for improving the clinker phase composition during the ball milling process. Background technique [0002] During the calcination process of desulfurized gypsum by calcination equipment, dihydrate gypsum is dehydrated into hemihydrate gypsum, but a small amount of anhydrous gypsum A3 is inevitably produced at the same time. For gypsum board production, what is needed is hemihydrate gypsum, the higher the content of hemihydrate gypsum, the more stable the production process and product quality. However, the existence of a small amount of anhydrous gypsum A3 increases the water demand and increases the water-to-plaster ratio, which affects the production process of gypsum boards and affects the bonding and strength of gypsum boards. [0003] Therefore, in the production process of plaster powder, we should use the characteristics ...
