Description

Superfine grinding assembly and superfine grinder

Technical Field

The utility model particularly relates to a superfine grinding assembly and a superfine grinder, which are suitable for the superfine grinding process of aquatic feed and belong to the technical field of feed production.

Background

During the processing of the feed raw materials, the feed needs to be crushed, so that the surface area of the feed is increased, and the digestion and absorption of animals are facilitated; on the other hand, the processing performance of the materials can be improved and enhanced, such as: the granularity of the materials is basically consistent through crushing, and the classification of the materials after uniform mixing is reduced; for trace elements and some minor component materials, the requirement of mixing uniformity can be met only by crushing the trace elements and the minor component materials to a certain degree and ensuring that the trace elements and the minor component materials have enough particle numbers.

For the pulverizer, particularly for aquatic feeds, a hammer mill is generally adopted to coarsely pulverize the raw materials, and in order to further increase the fineness of the particles, a superfine pulverizer is also required to pulverize the raw materials with higher fineness (the pulverizing granularity can reach 60-200 meshes), so that the stability of the granular feed in water, no collapse and the like are ensured before the aquatic breeding objects eat.

At present, materials in an ultrafine pulverizer are pulverized in a pulverizing chamber mainly by impact between a hammer head and a gear ring, and the shearing force is weak (as shown in figures 1-3). The raw materials contain more fiber raw materials, so that the raw materials are difficult to crush through the impact of the hammer head and the gear ring, and cannot be discharged through the classifying wheel, so that dead circulation is formed, and the crushing efficiency is affected. In addition, in order to further promote and strengthen the shearing operation to such raw materials, generally, the gap between the hammer teeth is smaller to strengthen the shearing action to the fiber raw materials, but the smaller gap between the hammer teeth can cause the higher wind speed of the crushing area, and partial raw materials are continuously circulated in the crushing chamber, so that the crushing efficiency is seriously affected.

As in the prior art "CN204503210U a feed superfine pulverizer", "CN201313058Y a superfine pulverizer", etc., it is disclosed that: the crushing area is formed by combining a hammer piece and a gear ring, and the impact action on the materials is weakened although the shearing operation on the materials in the crushing process is enhanced.
