试验室LX400;300型离心选矿机技术参数

一、简况

I. Introduction

        离心选矿机适用于-200目金属矿山的细泥，钨锡、钽铌、稀土矿、铜、铅、锌矿。

This centrifugal separator is  used for fine silt, tungsten and tin, formanite, rare-earth metal ore, copper,  lead, zinc ores in metal mines of -200 meshes.

        二、结构

II. Structure

        主机包括转鼓、底盘、给矿器、给矿嘴（上、下两个）、冲矿嘴、接矿槽、分矿器等。

It includes drum, chassis,  feeder, feeding mouth (one in the top and one in the bottom), washing mouth,  feed chute, feeder, etc.

        三、工作原理

III. Working Principle

        离心选矿机间断工作，但断矿、冲矿和分排精矿却是由指挥和执行机构自动进行的。指挥机构为一时间继电器，在规定时间内通人或切断电流。执行机构包括给矿斗中的断矿管、控制冲洗水的三通阀和皮膜阀，精尾矿换向排送的分矿器。它们分别由电磁铁带动动作。当达至规定的选别时间时，断矿管摆向回流管一侧，矿浆不再进入转鼓内。同时，三通阀将低压水路切断，皮膜阀上部的封闭水压被撤除，于是高压水即通过皮膜阀时入转鼓内。此时下部的分矿器也摆动到精矿管一侧，将冲洗下来的精矿导入精矿管道内。等待冲洗完毕，各执行机构分别恢复原位，继续对给矿进行分选。

The centrifugal separator works  intermittently, but the cutting, flushing, and separation of ores are  automatically performed by the command mechanism and actuating mechanism. The  command mechanism is a time relay which connects and disconnects power supply  within specified time. The actuating mechanism includes ore cutting pipe in the  feeding hopper, three-way valve and membrana dermalis valve that control  flushing water, and ore divider that concentrate and tailing are discharged in  different directions. They are driven to operate respectively by electromagnet.  When specified separation time is reached, the ore breaking pipe swings to the  one side of the return pipe and the slurry no longer enters the drum. At the  same time, the three-way valve cuts off the low pressure waterway. The closed  water pressure on the membrana dermalis valve is removed. Then when the high  pressure water passes the membrena dermalis valve, it enters the drum. At this  time, the ore distributing device also swings to the one side of the  concentrate pipe and lead the flushed concentrate into the concentrate pipe.  After flushing is finished, each actuating mechanism respectively restores the  original positions and continues to separate the feeding ores.
