Crushing system
Technical Field
The invention relates to a processing system in the field of feed machinery, in particular to a crushing system.
Background
Crushing devices used in crushing systems for the feed industry come in many forms, the most widely used of which are jaw and hammer crushers, in which the material enters the crushing chamber by gravity from the upper or middle part of the crusher and the crushed material exits from the lower part. When the material is subjected to high-speed centrifugal motion, a circulation layer rotating along the screen surface is formed, large particles in the material are accumulated on the outer ring of the circulation layer under the action of centrifugal force, small particles are accumulated on the inner ring of the circulation layer, the large particles block meshes and block the small particles from passing through the screen sheet, so that the crushing and screening efficiency is reduced, excessive crushing of the material and the increase of the material temperature are easily caused, and the crushing energy consumption is greatly increased.
The smaller the sieve holes are, the more obvious the material circulation layer is, the more serious the sieve sheet abrasion is, the more difficult the material is to pass through the sieve, and the further improvement of the capacity of the pulverizer is limited; some sticky and oily materials can easily cause the blockage of sieve holes, so that the effective screening area of the sieve sheet is reduced. When the material is collected by the saxophone, the needed pipeline is long when the outlet of the pulverizer is positioned below, the turning is more, the windage loss is large, and the power consumption of the fan is large.
Meanwhile, when the pulverizer feeds from above, the sieve sheet is easily broken by impurities such as stones, iron blocks and the like mixed in the materials, and an iron and stone removing device is often required to be added.
