Abstract

The present invention provides a horizontal molten compound fertilizer spraying granulation apparatus, which comprises a spraying device and a granulation tower, wherein the spraying nozzle of the spraying device is positioned at one side inside the granulation tower, the included angle between the spraying angle having the upward horizontal plane and the horizontal plane is 0-60 DEG, the height of the granulation tower is 10-40 m, and the length of the granulation tower is 30-100 m. According to the present invention, with the horizontal molten compound fertilizer spraying granulation apparatus, the raw material is sprayed from the side surface of the granulation tower, such that the raw material is sprayed in the angle inclined to the horizontal plane, the spraying range is long, the granule molding is completed in the horizontal tower, and the uniformity of the obtained product is good; and the tower height of the horizontal molten compound fertilizer spraying granulation apparatus is low, such that the small-scale molten granulation production is achieved, the molten granulation compound fertilizer can be achieved without high investment, and the production cost is saved.

Description

Technical field [0001] The invention belongs to the field of chemical fertilizer equipment manufacturing, and specifically relates to a horizontal molten compound fertilizer spray granulation device. Background technique [0002] The granulation process in the production process of granular compound fertilizer mainly includes agglomeration method, fluidization method, extrusion method, molten oil cooling method, and molten air cooling method. The molten air cooling method, also called tower granulation method, is divided into forced ventilation low tower method (generally within 60m high) and natural ventilation high tower method (generally above 60m high). [0003] CN1213964C discloses a method for producing granular multi-element compound fertilizer by granulating a low tower of molten slurry, which includes the following steps: a. Mixing and heating the compound fertilizer raw materials to melt; b. The molten slurry adopts a low tower with a height of 15-45m. The rotating granu...
