Compound chemical fertilizer production process

Abstract

The invention discloses a new process for producing blended compound chemical fertilizers. Existing processes are complex in flows, the cost of equipment in assembly lines is high, the production cycle of the chemical fertilizers is long and the efficiency is low. The process is characterized in that the flow is as follows: filling powdery materials into a tank and conveying the powdery materials from the tank to a feeder; introducing hot air into the feeder, conveying the powdery materials in the feeder to a drying mixer via the hot air and enabling the hot air to tangentially enter the drying mixer and rotate in the drying mixer; spraying liquid nitrogen fertilizers into the drying mixer, enabling the rotating hot air to drive powdery and liquid materials to rotate together to crystallize, dry and mix the materials and conveying the obtained compound chemical fertilizers to a collecting machine. The process has the beneficial effects that a plurality of steps are omitted and the amount of equipment used in the process assembly line is reduced, so that the cost of the assembly line is low, the production cycle is short and the efficiency is high.

Description

technical field [0001] The invention relates to the production of compound fertilizers, in particular to a process for producing blended compound fertilizers. Background technique [0002] The process steps of the existing compound fertilizer production line include crushing, metering, crystallization, mixing, granulation, polishing, drying, cooling, screening, baling, weighing, etc. The process is complicated and the cost of equipment in the assembly line is high , large area, large power consumption, high operating costs, large maintenance, high failure rate and other disadvantages; the production cycle of chemical fertilizers is long and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned prior art, and provide a new process for producing compound fertilizer without multiple steps such as granulation, polishing, cooling, etc., so as to simplify the process...
