脱 泥 机

分泥斗是一种结构简单的圆锥分级机，其外行为一倒立的圆锥，在液面中心设有给矿筒，圆筒底部处于液面以下一定深度。矿浆沿切线方向给入中心圆筒，经缓冲后由底部流出。流出的矿浆呈放射状向周边溢流堰流出去。在此过程中沉降过程速度大于上升速度的粗颗粒便沉在槽内，并经底部沉砂口批排出。细粒随表层矿浆进入溢流槽，作为溢流排出。给矿粒度一般小于2mm，分级粒度为74um以下。

分泥斗的特点是结构简单，不需要动力操作方便。现在分泥斗主要用在水力分级机前对原矿进行脱泥，以便提高分级效率，也可用在磨矿设备前为矿石浓缩、脱水，提高磨机给矿浓度，还可用在各种矿泥选别设备前控制给矿浓度。由于分泥斗的锥体体积较大，在生产流程中还兼有储矿作用。

Sub-bucket is a simple mud cone grading machine, its external behavior of an inverted cone, in the liquid center is equipped to the ore bins at the bottom of the cylinder a certAIn depth below the liquid level. Pulp into the center along the tangential direction to the cylinder through the buffer after the bottom of the outflow. Outflow to the periphery of the pulp radial flow to the overflow weir. In this process, the process of settlement increased faster than the speed of the cOArse particles will be submerged in the tank, and discharged through the bottom of the Spigot approved. With fine-grained surface of the pulp into the overflow tank, as the overflow discharge. To the ore particle size generally less than 2mm, grading granularity below 74um.
    Mud bucket is characterized by sub-structure is simple and easy to operate without power. Now sub-soil is mainly used in hydraulic bucket before the ore grading machine to de-mud, in order to improve classification efficiency, but also can be used in grinding equipment before the ore concentration, dehydration, improve the mill to the ore concentration, can also be used in a variety of mineral Mud control to the pre-sorting equipment, ore concentration. As the sub-buckets of mud cones larger, both in the production process also reserve mineralization.
