1借礦漿在槽面上自然流動進行分選的溜槽，有自動溜槽，皮帶溜槽
2借槽面搖動以強化松散分層的溜槽，有振動溜槽，搖動翻床，橫流皮帶溜槽以及雙聯(lián)選礦機
3借助離心力強化分層過程的溜槽，

Mud chute according to the working principle can be divided into three categories:

In 1 by the pulp groove on the surface of the natural flow of the automatic sorting chute, chute, chute belt

By the 2 groove surface to strengthen the loose stratification shaking sluice, vibration chute, swing over bed, cross belt chute and double concentrator

3 by means of centrifugal force hierarchical reinforcement process of chute,
