Pesticide granule production lineoverview

Equipment background and significance:Grain is one of the four prominent issuesIt is expected that by the middle of this century, the population will reach90Billion to100a hundred million If you want to feed the generals, they will be close1/5Population and farmers must have good harvests. The government and relevant research institutions have made significant contributions to ensuring good harvests in agriculture and the interests of farmers.Farmers cannot achieve good harvests without pesticides, which can be divided into powder, wettable powder, emulsion, suspension agent, and granule forms.

Granules（GranuleapproachGR）Abbreviated as granules, it is a granular preparation made by processing additives such as raw materials and carriers. Granules are derived from1946At the beginning of the year,50In the early years, it was widely used in the United States,60At the beginning of the decade, Japan began to extensively use it.60In the late 1960s, due to the development of environmental science, pesticide granules were used to avoid pollution to the environment and crops caused by particle drift during pesticide powder distributionWidely promoted and applied. The development of granules in our country mainly lies in70In the late years, the Ministry of Chemical Industry1989Annual statistics on the proportion of granules in the entire pesticide formulation7%about.

Pesticide granule production lineThe characteristics are:

① When applying pesticides, it has directionality, allowing the spread of pesticides to fully reach the target organisms and ensure the safety of beneficial organisms such as natural enemies;

② The medicinal granules do not adhere to the stems and leaves of plants, avoiding direct contact and causing phytotoxicity;

③ There is no dust flying during pesticide application, and it does not pollute the environment;

④ During the pesticide application process, it can reduce the operator's body attachment or inhalation of the dosage, avoiding poisoning accidents;

⑤ Reduce the toxicity of highly toxic pesticides and prevent poisoning of humans and animals;

⑥ Can control the release rate of active ingredients in granules and extend their shelf life;

⑦ Easy to use and highly efficient.

Some other medications for granulesIts characteristics make it a better medicine.

Pesticide granule production lineProcess flow and production equipment:

Process 1: Weighing ingredients → Making soft materials (trough mixer) → Granulation (YK-160 swing pellet machine) → Drying (CT-C series hot air circulation oven selects model according to production) → Screening (ZS oscillating screen selects model according to production) → Packaging

Process 2: Weighing ingredients → Mixing (high-efficiency wet mixing granulator) → Wet granulation (YK-160 swing granulator) → Drying (boiling dryer model selected according to production) → Screening (ZS-1000 oscillating sieve) → Packaging

Process 3: Weighing ingredients → Mixing (high-efficiency wet mixing granulator) → Granulation (XL-300 spinning granulator) → Shot blasting (can be selected according to process needs) → Drying (FG type boiling dryer, vibrating fluidized bed dryer choose model according to production) → Screening (ZS vibrating screen choose model according to production) → Packaging

Process 4: Weighing ingredients → Making soft materials (trough mixer) → Granulation (twin-screw extrusion granulator) → Drying (boiling dryer or vibrating fluidized bed dryer according to production capacity) → Screening (ZS vibrating screen) → Packaging

Process 5: Weighing ingredients → Mixing → Dry granulation machine → Screening → Packaging

Explanation: The above processes are in order, and the lower the order, the higher the density of the particles.

Suggested process: WDG water dispersible pesticide process and equipment flow:

Raw materials ->Mixing (dry materials) ->Airflow crusher ->Kneading (wet materials) ->Granulation ->Drying ->Screening ->Unqualified (large particles) ->Crushing (swing pellet machine) ->Re granulation If: Unqualified (small particles) ->Re granulation; Qualified packaging!
