What is the use of compound bentonite? How to prevent fertilizer agglomeration in the production of chemical fertilizer?

The main use of composite bentonite is as a binder. It is suitable for granulation of various compound fertilizers, special fertilizers, granular phosphate fertilizers, etc. Product performance can be divided into the following: it has the advantages of fast granulation speed, high sphericity, uniform particles, not easy to agglomerate and high particle strength. It has excellent adhesion, strong adsorption capacity and low density. It is the best choice for the ideal conditioning agent to prevent compound fertilizer agglomeration.

The clay is processed as a compound fertilizer granulating agent after being processed by dehydration, blending, grinding, and the like. It can be used for granulation of compound fertilizer, which has the characteristics of fast granulation speed, reduced returning material, uniform particle, smooth surface, high particle strength and good water solubility of fertilizer. Therefore, the production cost is saved, the mechanical fertilization is easy, and the strength can reach 18-45 Newtons after being tested.

It can maintain the energy efficiency of fertilizers and reduce the loss of fertilizer nutrients.

The compound fertilizer is usually used for 1-3 months from production to field use. During this period, maintaining the fertilizer efficiency of the compound fertilizer product is a very important problem. The compound fertilizer using clay as a granulating agent has adsorption properties due to clay. Nitrogen can be adsorbed through voids and channels in the crystal structure to reduce the rate of nitrogen volatilization, thereby reducing nitrogen loss. It is also conducive to the preservation of nutrients such as phosphorus and potassium, which can reduce the loss of effective nutrients in the compound fertilizer.

Performance 3: It can improve the utilization rate of fertilizer.

Due to the unique crystal structure of bentonite, its pore adsorption properties and electric field instability, on the one hand, the nutrient is absorbed into the crystal, and then slowly released to reduce the loss of nutrients, on the other hand because of the large ion exchange capacity of clay. .

A large number of ions are ion exchanged inside and outside. This process not only puts a variety of trace elements, but also stimulates the absorption of nutrients by the plants, thereby greatly exerting the fertilizer effect of the fertilizer and making the clay powder an ionic trace element mineral fertilizer.

Performance 4: Bentonite powder itself is a fertilizer that can improve the content of effective nutrients in the soil and reduce the amount of other fertilizers.

Clay powder is rich in a variety of useful macro-elements and trace elements of plants. Its porous crystal structure can increase its water retention capacity for sandy soils, and it can increase its water permeability for viscous heavy-slab soils. Adding clay powder directly to the soil can also achieve the effect of increasing crop yield.

Performance 5: Bentonite crystal fiber is slender, there are many internal channels, many grooves on the surface, and it has very strong hygroscopicity. Therefore, it can quickly absorb nitrogen fertilizer in production. Phosphate fertilizer is in free water and quickly becomes granulated bentonite to reduce Production energy consumption.
