Bentonite is a clay mineral of non-metallic minerals. Its unique characteristic different from other mineral products is its viscosity. The viscosity of bentonite can be used in many industries, such as drilling mud, coating chemical industry, compound fertilizer, geological prospecting, subway piling, etc. Multiple industries. The following is an introduction to the application of bentonite in compound fertilizer production.

First of all, compound fertilizer manufacturers use bentonite mainly for granulation and use as a binder for fertilizers. The 200 mesh bentonite powder of Raymond milling machine powder is used for the purpose of dehydration, blending, and grinding of compound fertilizers in fertilizer production. Compound fertilizer granulator. The granulation is a compound fertilizer, which has the characteristics of fast granulation speed, high ball formation rate, uniform granule, smooth surface, high granule strength, water-soluble fertilizer, etc., thereby saving the production cost of fertilizer.

　　Secondly, bentonite can be used as a carrier for compound fertilizers, and bentonite as a chemical fertilizer regulator also plays a role as a fertilizer carrier. As a carrier, bentonite can improve the physical properties of compound fertilizers and organic fertilizers, and increase the stability of fertilizers during transportation and storage. Bentonite also has the functions of nitrogen fixation, potassium fixation, and organic matter fixation, which can reduce the loss of fertilizers in the soil, control the release of nutrients from fertilizers, improve fertilizer utilization, and achieve the effect of increasing crop yields. As the carrier of slow-release fertilizers, bentonite has the effect of improving fertilizer efficiency and long-term slow-release effects. It also has the following advantages: ①Enhance compressive strength and reduce nitrogen volatilization; ②Control the release of nitrogen fertilizer; ③Increase crop yield.

A bentonite can be used as a compound fertilizer conditioner: In fertilizer production, according to the different properties of the fertilizer itself, adding a small amount of bentonite can reduce the water content, prevent the fertilizer from agglomerating, maintain a good looseness, and increase the particle size of the fertilizer. Transportation, storage and use of fertilizers. <br/>In addition to bentonite used in solid fertilizers, it can also be used as a suspending agent for fertilizer conditioners. Suspended fertilizer has the advantages of easy mechanization of storage, transportation and fertilization process, combined use with pesticides, herbicides and trace elements, convenient combined use, and large quantity. There are more applications in developed countries and some developing countries. Suspension fertilizer must be added to the suspension to maintain stability.

Bentonite can be used as a soil conditioner: when bentonite is applied as a fertilizer carrier to agricultural soil, it can absorb water and swell, change the ratio of solid, liquid and gas in the soil, loosen the soil structure and improve the physical properties of the soil. . Polluted soil environment is a very effective soil amendment in arid areas.

　　 Bentonite has high cation exchange capacity, strong water retention capacity and good cohesion. The cation exchange capacity is an important indicator of the supply of soil fertilizer and chemical fertilizer. Bentonite is used to improve the soil. In addition to powerful fertilizer and water retention, it can also improve the buffering capacity of the soil and absorb harmful elements in the soil.
