Abstract

The invention discloses a phosphate fertilizer preparation device and method, and belongs to the field of phosphate fertilizer production. The phosphate fertilizer preparation device comprises a barrel, a crushing mechanism, a supporting frame, a turnover mechanism, a bottom plate and a grinding mechanism, The crushing mechanism is mounted in the barrel to cut and crush a dephosphorized steel slag; the supporting frame is rotationally connected to the lower end of the barrel, so that the barrel rotates to enhance the crushing effect on the dephosphorized steel slag; the turnover mechanism is mounted at the lower end of the supporting frame, so that turnover of the barrel is achieved, and discharging and feeding are facilitated; the grinding mechanism is mounted at the upper end of the bottom plate to crush and grind the dephosphorized steel slag; and a sliding plate is slidably connected to the upper end of a box body, so that the box body is covered, and the dephosphorized steel slag is prevented from jumping out during grinding. The phosphate fertilizer preparation method comprises the following steps of crushing and grinding, adding hydrochloric acid and adding alkaline substances.

Description

technical field [0001] The disclosure belongs to the field of phosphate fertilizer production, and in particular relates to a phosphate fertilizer preparation device and method. Background technique [0002] With the continuous development of science and technology, the demand for phosphate fertilizer is increasing day by day. Phosphate fertilizer can be prepared from dephosphorized steel slag. With the increasingly strict requirements on phosphorus content in steel and the increase in phosphorus content in iron ore, many steel mills are The molten iron dephosphorization process is used in the steelmaking process. During the dephosphorization process of the molten iron, a large amount of dephosphorized steel slag will be separated. The dephosphorized steel slag is rich in phosphorus. Therefore, more and more fertilizer manufacturers use dephosphorized steel slag as raw materials. To produce and prepare phosphate fertilizer, the dephosphorized steel slag needs to be fully pul...
