Abstract

The invention discloses a high-nitrogen organic-inorganic compound fertilizer and a steam-free compound fertilizer pelleting equipment which comprises a drum and a heat generator; at least three pelleting areas are arranged in the drum, including a first pelleting area at front segment of the drum, a second pelleting area at the middle segment of the drum and a third pelleting area at the rear segment of the drum; a plurality of rows of material lifting devices are arranged in the first pellleting area; each row of material lifting devices consists of a plurality of material lifting plates including rows of inclined material lifting plates and rows of horizontal material lifting plates which are arranged in an intercrossed manner; a plurality of baffle rings are arranged on the inner wall of the second pelleting area; a plurality of rows of material lifting devices are arranged in the the third pelleting area and each row of material lifting devices consists of a plurality of inclined material lifting plates which are put in order; the heat generator is a high temperature blowing mechanism; and the inclination direction of the inclined material lifting plates is the same as the blowing direction. After adopting the new steam-free pelleting technology, the invention realizes the effect that the drum can pellet without steam, thereby a steam boiler is omitted, thus the investment, the energy consumption and the production cost are reduced, and the unsafe factors are avoided.

Description

(1) Technical field: [0001] The invention relates to fertilizer production equipment, in particular to high-nitrogen organic-inorganic compound fertilizers and steam-free granulation equipment for compound fertilizers. (two) background technology: [0002] The methods currently used to produce compound fertilizers with high nitrogen content and organic-inorganic compound fertilizers are drum steam granulation or urea melt granulation. The production of compound fertilizer by drum steam granulation is a thermal granulation process, and its working principle is to increase the solubility of salts in the granulation water system material by increasing the temperature of the material, thereby achieving the satisfaction of the material under low moisture content. The amount of liquid phase required for granulation, the material depends on the surface tension, the appropriate amount of liquid phase, the extrusion force generated by rolling between materials, and the correct moveme...
