3) The other elements and the premixed trace elements are simultaneously put into a continuous forced mixer, so that the trace elements and the other elements are secondarily mixed.
As shown in fig. 5, the specific operation is that 211 parts of urea is put into a buffer bin from a feeding port 1, and then enters an integral mixing bin after being measured by a constant feeder; 330 parts of monoammonium phosphate are put into the buffer bin from the feed inlet 2, and then enter the integral mixing bin after being measured by the constant feeder; 440 parts of potassium nitrate, 3.5 parts of boric acid, 8.0 parts of EDTA chelated iron, 3.3 parts of EDTA chelated zinc, 4.0 parts of EDTA chelated manganese and 0.2 part of ammonium molybdate heptahydrate are all simultaneously thrown into the feed inlet 4 and then enter a paddle mixer to be stirred and mixed for 2 min.
The raw materials are measured and conveyed to a continuous forced mixer: the materials are fed into the equipment from a feeding port and conveyed to the right under the action of a fourth motor and a third spiral piece. Then, under the effect of second paddle, the material is picked up and continues to the right, and whole process plays the function of carrying, mixing, and until the material conveys the drain hole, then packs. The barrel is fixed, and the mouth of respiration uses PPS fiber material sack to seal, plays the effect of balanced equipment inside atmospheric pressure for the dust is not excessive.
Comparative example 1: as shown in fig. 6;
the specific formula is unchanged from the example 1, and all the materials are directly put into the system through the feed ports in sequence, wherein the trace elements are independently put into the system through the feed ports of the same feed port, mixed by a drum mixer and then packaged;

Comparative example 2: as shown in fig. 7;
in the same way as example 1, a premixing process was added, a 1000L paddle mixer was used to premix trace elements with one of the macroelements in proportion, a drum mixer was used to mix the materials entering the equipment, and then packaging was performed. Because the feed inlet can not be completely sealed, the dust is large, and a bag-type dust remover is required to be additionally arranged;
