Fertilizer pulverizer

Abstract

The invention relates to a fertilizer pulverizer. The pulverizer comprises a base (1) and a power system (6), the base (1) is provided with a pulverizing chamber (2), the upper part of the inner wall of the pulverizing chamber (2) is fixedly provided with a tooth ring (10), the lower part of the inner wall of the pulverizing chamber (2) is provided with a plurality of floating dead knife rings (9), the inner ring wall of each of the plurality of floating dead knife rings (9) is uniformly provided with a plurality of dead knives (11), and the inner ring wall of each of the plurality of floating dead knife rings (9) is vertically provided with a straight groove. The fertilizer pulverizer has the advantages of good pulverizing effect, small jittering and low noise.

Description

technical field [0001] The invention relates to a pulverizer, in particular to a pulverizer used for pulverizing organic fertilizers with high water content, and belongs to the technical field of pulverizing machinery. Background technique [0002] Fertilizer pulverizer is one of the essential equipment in the industrial production of commercial organic fertilizers. The current fertilizer pulverizer has strict requirements on the moisture content of the crushed materials. Generally, the moisture content is required to be lower than 15% (test data), resulting in There must be a drying process before granulation in the industrial production process of commercial organic fertilizers. However, the sphere formation mechanism of general organic fertilizers requires the minimum moisture content of materials to be between 25% and 40% (test data), which makes Crushing and granulation become a pair of contradictions. In order to solve this pair of contradictions, the current productio...

Problems solved by technology

[0009] From the above process flow, we can see that there are repeated drying and water spraying processes in the whole process, which not only reduces the survival probability of microorganisms, but also increases the production cost of commercial organic fertilizers, which is a serious waste of energy and is not conducive to commercial production. For the industrialization of organic fertilizers, in order to solve this contradiction, we have invented a pulverizer suitable for crushing materials with high moisture content; The flying knife structure crushes the powder, but in actual use, it is found that this kind of flying knife structure is actually just a hammer structure. When working, it only throws the blade out to hit the fertilizer, but cannot provide shearing capacity. Because the fertilizer It has a certain toughness, so it is often impossible to cut it smoothly, so the crushing effect is not ideal; at the same time, in use, due to the collision between the fertilizer and the wall of the crushing chamber, the crusher shakes seriously and the noise is very loud
