Description

[0001] The present invention relates to a grinding apparatus having a multi-stage grinding structure,

The present invention relates to a pulverizing apparatus having a multi-stage pulverizing structure, and more particularly, to a pulverizing apparatus having a multi-stage pulverizing apparatus which is provided at a predetermined interval in the interior of a housing body so as to crush an object such as a material or food waste, The object of the present invention is to provide a pulverizing apparatus having a multi-stage pulverizing structure in which objects are pulverized while moving in a multi-stage pulverizing section to increase the pulverization efficiency, and a troublesome problem of pulverizing the object to be pulverized again is not caused .

In general, a number of methods for treating food waste generated in homes, restaurants, etc. have been used. However, landfilling in this treatment method poses many problems such as contamination of ground water and securing of odor and landfill by leachate. In contrast, In the case of using it as a non-agricultural area, transportation costs due to transportation are large in the cities, and hygienic management is required for using as livestock feed, and economic processing is a big problem due to the secondary treatment process.

When the landfill is used with inexpensive treatment method, bad odor is generated, and the living conditions around the landfill are deteriorated and the environmental pollution caused by the contamination of the drinking water source by the leachate causes social problems due to friction with the residents.

In recent years, in order to improve such disadvantages, as disclosed in Korean Utility Model Application No. 20-2006-0010371, enzymes and microbial fermentation and extermination devices have been developed and used.
