Embodiment 1

[0016] Embodiment 1: stearic acid granulation

[0017] The method for stearic acid granulation of the present invention may further comprise the steps:

[0018] 1) Put 200KG liquid stearic acid in the storage tank 1, keep the steam at 80°C, install the high-temperature liquid pump 2 from the bottom of the storage tank 1, connect the outlet of the high-temperature liquid pump 2 to the nozzle 3, and adjust the nozzle 3 to 45 degrees upward ;

[0019] 2) if figure 1 As shown, after the installation of the subsequent roller slicer 4 and the collection bin 5 is completed, the circulating cooling water (8° C.) of the roller slicer 4 is turned on for 10 minutes, and then the roller slicer 4 is turned on.

[0020] 3) Turn on the stearic acid pump 2, and adjust the opening and closing of the valve in front of the nozzle 3, so that the stearic acid ejection trajectory is basically perpendicular to the tangent line of the contact cylinder surface. The stearic acid solidifies on the su...

Abstract

The invention discloses a new drum-type granulating method and a granulating device, and the new drum-type granulating method is as follows: a to-be-granulated liquid material is sprayed by an upward oblique spray head, and falls down in a parabolic trajectory, a drum slicer is placed at the landing point, the material is cooled on a drum of the drum slicer to form a hemisphere solidified on the surface of the drum, and then through a drum machine knife edge the material is smoothly broken away. The material can be evenly produced by control of the nozzle angle, the spray pressure and the drum rotary speed. The new drum-type granulating method is applicable to chemical raw materials with the melting point of 50-100 DEG C and good fluidity, the investment cost and the operation cost are reduced greatly, and the technical process is simple and easy to operate, and is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a chemical raw material granulation method and a device thereof, in particular to a chemical raw material drum granulation method and a granulation device thereof. Background technique [0002] At present, the commonly used granulation methods in the chemical industry include compression granulation, crushing granulation, spray drying granulation, extrusion granulation, coagulation granulation, and fluidized spray granulation. Various granulation methods are used in the field of material granulation with different characteristics. Generally, materials with low melting point and relatively good fluidity are spray-dried and fluidized spray granulated. However, the price of these two granulation equipment is relatively high, the composition is complicated, and the use and maintenance are difficult. For some small and medium-sized enterprises, they cannot adapt to the high ...
