CN103623895A - Method for crushing garbage by utilizing ball grinding mill - Google Patents

Abstract

The invention relates to a method for crushing garbage by utilizing a ball grinding mill, which belongs to the technical field of solid waste disposal and is suitable for garbage disposal. The garbage mentioned in the invention conceptually contains mixed living garbage, kitchen wastes and kitchen garbage. The method comprises the following steps: directly sending the garbage without sorting and water into the ball grinding mill for wet crushing, and then conducting water separation. The method has the advantages that as the proportions of ingredients in the garbage are different after the garbage is crushed, the ingredients are easily classified, and the sorting operation is greatly simplified. As the particle size gets smaller, the subsequent resource utilization is also facilitated.

Description

A kind of method of utilizing ball mill to pulverize rubbish

Technical field

The invention belongs to Solid Waste Treatment technical field, be applicable to the needs of garbage disposal, the rubbish concept of mentioning in the present invention contains mixed consumer waste, changing food waste, rubbish from cooking.

Background technology

The feature of rubbish is that moisture content is high, complicated component, and its composition can be divided three classes: light rubbish, heavy rubbish, perishable rubbish.

Light rubbish mainly comprises: plastics, bamboo wood, textile etc.

Heavy rubbish mainly comprises: masonry sand, concrete block, glass, pottery, metal etc.

Perishable rubbish mainly comprises: food garbage, waste paper etc.

Current technology of garbage disposal is except burning and landfill, and other technology all needs rubbish first to carry out sorting, pulverizing, then just can carry out the utilization of resources; Because msw water content is high, complicated component, be difficult to sorting, pulverizing, cause this class technology to be difficult to large-scale promotion application.

Object of the present invention is exactly that a kind of technology that can solve refuse classification, pulverize a difficult problem will be provided.

Summary of the invention

Ball mill is Universal disintegrating equipment, is mainly used in the pulverizing of inoganic solids, is characterized in not being afraid of that material water ratio is high, complicated component, can pulverize, and treating capacity is large, durable, operating cost is low, can meet the needs of extensive processing.

Content of the present invention is: rubbish, without sorting, is directly sent into and in ball mill, carried out wet pulverizing, and then carry out wet concentration together with water.

The advantage of doing is like this: after the various compositions pulverizing in rubbish, because proportion is different, be easy to classification in water, sorting is simplified greatly, because granularity diminishes, also facilitated follow-up recycling.

The specific embodiment

In one embodiment of the invention, the flow process of the inventive method is: rubbish, without sorting, is directly sent in ball mill and carried out wet pulverizing together with waste liquid, form after fluid flows out ball mill and carry out wet concentration again.

Claims (1)

1. a method of utilizing ball mill to pulverize rubbish, is characterized in that: rubbish, without sorting, is directly sent into and in ball mill, carried out wet pulverizing, and then carry out wet concentration together with water.
