Abstract

The invention discloses a granulation device, and aims at solving the problem that the performance of a crusher is reduced due to a stable circulation layer. The granulation device comprises a rotor, hammer sheets which rotate around a rotor shaft on the rotor, and sieves enclosing the hammer sheets, wherein the adjacent sieves are connected with each other through a press sieve plate; a plurality of cut ribs which are raised inward a crushing chamber; every two cut ribs are parallel to each other and vertical to the axis of the rotor shaft; a cut groove is formed between every two cut ribs; and the top end of the rotary circumference of each hammer sheet penetrates through each cut groove. When the granulation device is used, the cut ribs can retard the circulation layer, so that the hammer sheets can strike materials more effectively. The granulation device can be applied to a hammer mill, so that the efficiency of the hammer mill can be greatly improved.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a granulation device. Background technique [0002] At present, hammer mills are mainly used for crushing large-diameter materials. There is a rotor in the crushing chamber, and the rotor is installed on the rotor main shaft. Both ends of the main shaft are supported on the frame through bearing seats. On the main shaft, there are a number of pin shaft holes evenly distributed on the hammer frame plate. The pin shafts are installed in the pin shaft holes. The hammer blades are installed on the pin shafts and separated from each other by spacers. The outer periphery of the rotor is provided with a dense net surrounding the rotor. There are sieves with holes, and the adjacent sieves are connected to each other by pressing the sieve plate. [0003] When the pulverizer is working, the material enters the crushing chamber, and at the same time, the external power source drives the rotor to rota...
