Description

A kind of composite coated fertilizer adding attapulgite clay and preparation method thereof

Technical field

The present invention relates to fertilizer field, particularly a kind of composite coated fertilizer adding attapulgite clay and preparation method thereof.

Background technology

Attapulgite is earthy, compact mass originates in sedimentogeneous rock and in weathering crust, color is in white, and canescence, Steel Gray, greyish-green or weak satin luster, soil property is fine and smooth, and have oily soapy, light weight, property are crisp, and fracture is conchoidal or irregular shape, and water-absorbent is strong.Attapulgite clay can as fertilizer component, as composite fertilizer's binding agent, granulating and forming rate is high, and the time is short, and institute's granule strength of making is high, surface smoothness is good, the fertilizer conservation time is long, therefore this binding agent, can improve throughput, reduce power consumption, the consumption of the high price such as talcum powder, ammonium chloride raw material can also be saved; Using attapulgite as the suspension agent of agricultural chemicals and carrier, produce specific pesticide, can drug effect be extended, long quality-guarantee period, and reduce pesticide producing cost; Make the coal briquette binding agent of fertilizer plant's gas, cohesive force is strong, and intensity is high, and cost is low, and gas making rate is high, also can improve coal briquette fixed carbon content, reduces dust pollution etc.
