Problems solved by technology

The foregoing arrangement has been found to result in the formation of some agglomerates, possibly due to the heat and pressure generated by the interaction of the screw 66 with the developer material 56 in the reduced region 68
As noted above, the formation of agglomerates leads to undesired print defects when using toner cartridges containing those agglomerates

Abstract

A system for transferring a particulate material from a first container to a second container including an upper portion, a lower portion and a sieve. The upper portion having a housing and a high frequency vibrator, the housing having a first end, a second end opposite the first end, and a gasket positioned adjacent the first end. The lower portion having a collector funnel, a low frequency vibrator and a collar securing the low frequency vibrator to the collector funnel. The sieve having a mesh size, a perimeter and a gasket positioned adjacent the perimeter. The upper portion is releasably secured to the first container and the sieve is releasably secured between the second end of the upper portion and the lower portion.

Description

technical field [0001] The presently disclosed embodiments relate to providing an apparatus for processing particulate material, more particularly to processing fine particulate material, and more particularly to processing fine particulate material to prevent the formation of agglomerates and Prevent transfer of agglomerates from one container to another. Background technique [0002] Fine particulate materials, especially ultrafine particles, often become agglomerated during packaging, shipping, storage, subsequent handling, and the like. Agglomeration can occur for various reasons, eg humidity, temperature, pressure. Agglomeration of particulate materials may adversely affect the subsequent use of those materials. For example, agglomerates of xerographic developer material (ie, a mixture of carrier and toner particles) can result in banding or streaking when used in xerographic printing equipment. [0003] Agglomeration of granular material is found to be particularly ...
