Classifier is used to soon to binary channels

The utility model provides a classifier is used to soon to binary channels, include and overlap shell body (2), interior casing (8) and the gas -solid import pipe of establishing (1) in proper order in the extroversion, interior casing (8) and gas -solid import pipe (1) is the open tubular structure in both ends from top to bottom, forms outer toroidal cavity between shell body (2) and interior casing (8), toroidal cavity in the formation between interior casing (8) and the gas -solid import pipe (1), and the sub -unit connection of shell body (2) has powder -return pipe (9), and the upper portion of shell body (2) is connected with export (3). This classifier is used to soon to binary channels will impact the separation and give first place to and change centrifugation into and give first place to, and increase fluidizing air, make that separation efficiency is higher, the evenness index is higher. 本实用新型提供了种双通道旋惯粗粉分离器，包括从外向内依次套设的外壳体(2)、内壳体(8)和气固进口管(1)，内壳体(8)和气固进口管(1)均为上下两端开放的筒形结构，外壳体(2)与内壳体(8)之间形成外环形空腔，内壳体(8
