Crushing system for phosphorus-containing gypsum

Abstract

The invention discloses a crushing system for a phosphorus-containing gypsum. The system comprises a working platform, wherein a feeding port is formed in one side of the working platform, and a feeding pipeline is arranged at the bottom end of the feeding port; a rotating motor is arranged at one side of the feeding port, and a control panel is arranged at one side of the rotating motor; a crushing groove is formed in the bottom end of the working platform; a first rotating shaft and a second rotating shaft are arranged in the crushing groove; a first blade is arranged on the surface of the first rotating shaft, and a second blade is arranged on the surface of the second rotating shaft; a transverse plate is arranged at the bottom end of the crushing groove, and a discharging port is formed in the middle part of the transverse plate. According to the system, the crushing groove is provided, and two rotating blades are arranged in the crushing groove and are staggered and engaged witheach other during being rotated, so that the phosphorus-containing gypsum can be completely crushed, and both time and force can be saved; a motor is connected to the working platform through a bolt,and the blades can be replaced in any time. The system is reasonable in design, simple in structure, safe, reliable, and convenient to use.

Description

technical field [0001] The invention relates to a crushing device, in particular to a phosphorous gypsum crushing system. Background technique [0002] Phosphogypsum: refers to the solid waste generated when sulfuric acid is used to treat phosphate rock in the production of phosphoric acid, and its main component is calcium sulfate. The main components of phosphogypsum are: CaSO4·2H2O, and it also contains many other impurities. Phosphogypsum is generally powdery, and its appearance is generally grayish white, grayish yellow, light green and other colors, and it also contains organic phosphorus, sulfur and fluorine compounds, with a bulk density of 0.733-0.88g / cm3 and a particle diameter of 5-15um. Its main components are Calcium sulfate dihydrate, its content can generally reach about 70-90%. The secondary components contained in it vary with the origin of phosphate rock, and generally contain rock components Ca, Mg, phosphate and silicate. my country currently discharges...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome that the existing phosphogypsum crushing device is difficult to completely crush it during the crushing process, which makes repeated work, time-consuming, uneven size, low production efficiency, and relatively large volume of crushed materials. Large, low-efficiency treatment problems, providing a phosphorus-containing gypsum crushing system
