Embodiment Construction

[0039] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0040] Such as figure 1and Figure 7 As shown, the phosphogypsum crushing and drying powder production line includes a rotary kiln 3, a crusher, a frying furnace and a ball mill. The finished gypsum powder is obtained by kiln calcination and ball mill grinding. The rotary kiln 3 is installed between the kiln head cover 1 and the kiln tail smoke chamber 2. Tropical zone 3.1, transition zone 3.2, firing zone 3.3 and cooling zone 3.4.

[0041] As an improvement, such as figure 1 As shown, the rotary kiln 3 is set as a high-temperature rotary kiln for anti-blocking material phosphogypsum. The inner walls of the preheating zone 3.1, the transition zone 3.2 and the firing zone 3.3 of the anti-blocking material phosphogypsum high-temperature r...

Abstract

The invention discloses a phosphogypsum crushing and drying powder production line. The phosphogypsum crushing and drying powder production line comprises a rotary kiln (3), a crusher, a frying furnace and a ball mill. A phosphogypsum wet base is dried and dehydrated in the rotary kiln (3), sent to the crusher (3) to be crushed, and then calcinated and grinded through the frying furnace and the ball mill correspondingly to prepare the finished gypsum powder, the rotary kiln (3) is installed between a kiln hood (1) and a kiln tail smoke chamber (2), the rotary kiln (3) is a anti-blocking material phosphogypsum high temperature rotary kiln, and the frying furnace is a blast type phosphogypsum powder frying furnace. An anti-blocking screw for avoiding blocking is arranged in the rotary kiln, a flow deflector which can improve the conveying speed is arranged in the baking section of the rotary kiln, a cooling belt is provided with a water cooling structure for cooling the material by replacing a cooler, the structure of the frying furnace is improved to increase the processing phosphogypsum efficiency of the production line, production cost is reduced, and the enthusiasm of enterprises to use the phosphogypsum is improved.

Description

technical field [0001] The invention relates to the field of phosphogypsum processing equipment, in particular to a phosphogypsum crushing and drying powder production line. Background technique [0002] Monoammonium phosphate is a good flame retardant and fire extinguishing agent, widely used in fire retardant of wood, paper and fabric, and also used as dispersant in fiber processing and dye industry, glaze for enamel, compounding agent for fireproof coating , dry powder fire extinguishing agent, medicine and printing industry, etc. are also used. According to the manufacturing process, there are wet method production of monoammonium phosphate and thermal method production of monoammonium phosphate. With the strict control of energy use by the state and departments at all levels, the production energy consumption of wet method phosphoric acid is lower than that of thermal method phosphoric acid, and the product index can To meet various requirements, wet-process phosphoric...
