Abstract

The invention relates to equipment and a process for adjusting the moisture of granular materials and grading the granularity, in particular to a fluidized bed winnowing and moisture controlling machine and a new winnowing and moisture controlling process which can simultaneously realize the reduction of water content of the granular materials and the grading according to the granularity of the granulated materials. Fine granular materials of the granular materials in the fluidized state are centrally discharged through a fine granule discharge pipe and other rough granular materials are scraped to a rough granule discharge pipe for centralized discharge, so the proper reduction of the water content can be realized while grading the granularity. The equipment and the process are applied to the field of coal moisture control in the coking industry, the dryness and quality improvement of lignitous coal in coal industry and the like.

Description

Technical field [0001] The invention relates to equipment and technology for humidity adjustment and particle size classification of granular materials, in particular to a fluidized bed air separation and humidity control machine and a new air selection and humidity control process that can simultaneously reduce the moisture content of granular materials and classify granular materials according to their particle size. Background technique [0002] At present, there are many equipments that only reduce the moisture of granular materials, and there are also many equipments that only classify the particle size of granular materials. Some industries and occasions require not only reducing the moisture of granular materials, but also requiring classification according to the particle size of granular materials, such as the coking industry. There are such requirements for "coal humidity adjustment" in the coal industry and "lignite drying and upgrading" in the coal industry. The ...
