Aeration lump traps are ideal when large lumps are present in material.  Lumps are generally created in the silo by moisture and are typically unacceptable for the consumer's vehicle being loaded.  The lump trap eliminates large lumps by creating a gravity air trap inline with a aeration conveyor.  This is accomplished by passing low pressure air through an overlapping configuration of porous membrane media and into the bed of the material being handled.  Heavy lumps fall and are caught in the bottom of the lump trap which automatically empties using a level sensor accompanied by a series of slide gate valves.  A large variety of materials can be handled with aeration lump traps regardless of their abrasive nature or bulk density.  The criteria are particle size, moisture content, and temperature.  Moisture content should be below 1% and temperature can not exceed 1200 degrees Fahrenheit [649? C].

The integration and ease of use make the aeration lump trap an economical means to eliminate large lumps from the material stream.  DCL offers product compatibility tests in order to determine optimum conveying angles and aeration volumes.  A minimum product amount of 2 cubic feet [0.07 m?] is required to conduct a proper test.

DCL offers a selection of aeration lump traps from 6 inches [152 mm] wide up to 36 inches [914 mm] wide and conveying capacities up to 1000 cubic feet per minute [28.3 m?/min].  Lump traps also are available in a high top or low top design allowing for maximum flow rate or minimum head room depending on the application.

A choice of construction materials allow handling of all types of products; fine, granular, lumpy, abrasive, corrosive, and sanitary applications.  A choice of electrical options are also available allowing for installation in almost any environment; NEMA 4, NEMA 4X, NEMA 7, NEMA 9, 120V/220V control, 460V/415V power, etc.
