Device for improving composition of clinker phase in ball milling process

Abstract

The embodiment of the invention discloses a device for improving composition of a clinker phase in a ball milling process. The device for improving the composition of the clinker phase in the ball milling process comprises a moisture emission chimney, an induced draft fan, a hollow cylinder reamer and a ball mill body which are connected in order; and the device for improving the composition of the clinker phase in the ball milling process further comprises a rotary joint and a rotary air jet opening, an air inlet of the rotary joint is connected with an air outlet pipeline of the induced draft fan, a central rotary shaft located at the internal axial end of the hollow cylinder reamer is slidably connected to the right end of the rotary joint, the outer wall of the central rotary shaft isarranged as a hollow structure, spiral hinged blades are further fixedly connected to the outer surface of the central rotary shaft, the rotary air jet opening is connected to the right end of the hollow cylinder reamer, the rotary air jet opening is formed in the ball mill body, and a feeding hole is formed in the outer wall of the upper side of the hollow cylinder reamer. According to the devicefor improving the composition of the clinker phase in the ball milling process, the content of anhydrous gypsum A3 in calcined gypsum is reduced, the water paste ratio during gypsum board productionis further reduced, so that energy consumption is reduced, and the action of improving panel bonding and strength is achieved.

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 ...
