Compact deduster with cyclonic air recycling

A particulate material dedusting system comprising:

• a dedusting apparatus including:
• a product inlet port for the introduction of a flow of contaminated particulate material into said dedusting apparatus;
• a magnetic flux field generator associated with said product inlet port to subject said flow of contaminated particulate material to a magnetic flux field to neutralize static charges on said particulate material;
• a product outlet port for the discharge of cleaned particulate material from said dedusting apparatus;
• at least one air wash deck positioned between said product inlet port and said product outlet port to receive said flow of contaminated particulate material from said product inlet port;
• an air inlet port for the introduction of a clean air stream into said dedusting apparatus, said clean air stream being directed through said at least one air wash deck to pass through said flow of contaminated particulate material and remove contaminates therefrom to create a contaminate-laden air stream;
• and
• an air discharge port for the discharge of said contaminate-laden air stream from said dedusting apparatus;
• a cyclonic separator connected by first ductwork to said air discharge port to receive said contaminate-laden air stream therefrom and discharge a partially cleaned stream of air;
• an inline filter connected by second ductwork to said cyclonic separator to receive said partially cleaned stream of air from said cyclonic separator, remove remaining contaminates in said partially cleaned air stream, and discharge said clean air stream;
• and
• a fan connected by third ductwork to said inline filter to receive said clean air stream, increase a velocity property of said clean air stream, and directed said clean air stream into said air inlet port of said dedusting apparatus, said first, second and third ductwork defining a closed loop system to receive said contaminate-laden air stream from said air discharge port of said material dedusting apparatus and deliver said clean air stream to said air inlet port of said material dedusting apparatus without discharging air therefrom.

A closed loop particulate material dedusting system comprising:

• a frame movably positionable in conjunction with a flow of particulate material;
• a dedusting apparatus mounted on said frame and including a product inlet port, an air wash deck, and a product outlet port for the gravity induced flow of contaminated particulate material through said dedusting apparatus, said dedusting apparatus further including an air inlet port for the introduction of a clean air stream into said dedusting apparatus, said clean air stream being directed through said air wash deck to pass through said flow of contaminated particulate material and remove contaminates therefrom to create a contaminate-laden air stream for discharge through an air discharge port;
• a magnetic flux field generator associated with said product inlet port to subject said flow of contaminated particulate material to a magnetic flux field to neutralize static charges on said particulate material;
• a cyclonic separator mounted on said from and being connected by first ductwork to said air discharge port to receive said contaminate-laden air stream therefrom and discharge a partially cleaned stream of air;
• an inline filter mounted on said frame and being connected by second ductwork to said cyclonic separator to receive said partially cleaned stream of air from said cyclonic separator, remove remaining contaminates in said partially cleaned air stream, and discharge said clean air stream;
• and
• a fan mounted on said frame and being connected by third ductwork to said inline filter to receive said clean air stream, increase a velocity property of said clean air stream, and directed said clean air stream through fourth ductwork into said air inlet port of said dedusting apparatus for use to remove contaminates from said flow of contaminated particulate material.
