Description

{CRUSHING APPARATUS FOR WASTES}

The present invention relates to a waste crushing apparatus, and more particularly, to a waste crushing apparatus that effectively breaks, crushes, and cuts a waste, and separates foreign matter contained in the waste to facilitate processing of the waste.

Generally, waste is mixed with various materials such as metals, plastics, fibers, paper, and vinyl. Conventionally, such wastes are buried or incinerated in the entire amount without screening, resulting in an increase in waste disposal cost and environmental pollution.

On the other hand, resource depletion is becoming serious worldwide, and as a countermeasure, waste is recycled and used as a raw material for the product or as a fuel to replace fossil energy.

However, in general, various kinds of wastes are included in the waste bag, and when the wastes are selected through the manpower, a lot of manpower is required for the sorting work, and the amount of waste to be treated is also limited.

Accordingly, many studies have been made to efficiently select and process wastes. For example, domestic registration utility model 20-0193138 discloses a plurality of roller devices for pulverizing waste. However, the prior art includes a pair of rollers having a small diameter and a large diameter, and it has not been easy to precisely control the number of revolutions or the rotational speed of each roller. Further, there is a problem that the waste is caught in the spiral groove formed in the roller or is pressed and fixed, which makes it difficult to maintain and repair the apparatus.
