The main factors of compound fertilizer agglomeration are: with the change of temperature and humidity, the compound fertilizer produces moisture absorption → surface dissolution → evaporation → crystallization, which forms a crystal bridge and agglomerates. It has a direct relationship with water, and is also a fertilizer with moisture absorption. Characteristics and nature are determined. Compound fertilizer surface treatment is the most effective way to solve the agglomeration.
Compound fertilizer anti-caking surface treatment agent--method use:
one. Product Overview:
The product is a flake-like concentrate, which is mixed with 68# mechanical oil or naphthenic oil, and then heated to 80 ° C ~ 90 ° C to be sprayed into the surface of the particles. Achieve anti-caking, anti-powdering, and improve the utilization of fertilizer nutrients.
two. Physical properties:
Appearance: white or light yellow flakes Freezing point: 50 ° C
Dynamic viscosity: CP150 flash point: >150°C
three. Anti-caking agent mixing program:
Mixing ratio: 25% amine film, 68# mechanical oil or naphthenic oil 75%
The mechanical oil is first heated to 80 ° C, and then added to the amine sheet for 30 minutes, at which time the temperature can rise to 90 ° C ~ 95 ° C. When using, the temperature in the oil storage tank should be maintained at 85 °C ~ 90 °C.
four. Dosage:
For each ton of compound fertilizer, it is necessary to use 2 æ··åˆ of the mixed coating agent and 5 ‰ talcum powder.
Fives. effect:
Through the surface treatment of the compound fertilizer, it can be kept loose in the warehouse for about six months.
six. The main equipment name and specifications of compound fertilizer anti-caking:
Equipment name Quantity (set) Specifications (mm)
Coating machine 1 Φ=1200 L=3000
Anti-caking agent oil storage tank 2 Φ=500 H=600
Air compressor 1 pressure 3~5 kg
Atomizing nozzle 1 imitation import
Screw speed conveyor 1 Φ=114 L=4000
Talc hopper 1 matched with screw speed conveyor
Seven. Process Description:
When the finished particles uniformly flow into the rotating coating machine and continuously roll, the prepared oily mixed coating agent is sprayed into the surface of the particles by means of compressed air and a spray head. Then, using a spiral speed conveyor (adjusting the flow rate of talc powder), the talc powder is pounced on the surface of the particles to form an anti-caking film on the surface of the compound fertilizer particles, thereby achieving the anti-caking effect.
Eight. Anti-caking agent - purchase of amine tablets:
Wuxi Xinghua Compound Fertilizer Research Institute is the first unit in China to promote compound fertilizer anti-caking agent. The amine tablets produced have accounted for about 40% of the national use since the promotion in 1996. The anti-caking effect has been recognized by many large and medium-sized compound fertilizer plants across the country. Perennial supply, the price is excellent, can be checked on behalf of the agent.
nine. Anti-caking agent equipment procurement:
Our set of coating equipment provided by Xinghua Compound Fertilizer Research Institute has three bags of quality and can be used for on-site commissioning and other technical services. Units with equipment manufacturing capabilities, we can also provide a full set of packaging machine production drawings, self-manufacturing, installation, which can save investment.
