結構簡介

Structure

本機由勵磁系統、傳動機構、給礦系統及產品清掃收集部分所組成。

This machine consists of excitation system, transmission mechanism, feeding system, as well as product cleaning and collection part.

1、勵磁系統：

1. Excitation System

由固定磁極，輥子旋轉磁極和裝在兩者之上的勵磁繞組及激磁直流電源所組成，上下兩磁極平行排列。由直徑為120毫米兩個輥子與下部平面磁極構成封閉磁回路。兩磁極的工作間距可通過增減墊板進行調整。通過調節高壓器的電壓使硅元件供給固定勵磁繞組和經電刷供給輥子旋轉磁極勵磁繞組的直流電流，可從需平滑地升至額定值2安培，為適應不同礦種的選別需要本機磁場強度范圍可分為強磁場和弱磁場兩種，由面板上磁場選擇開關進行選擇。當分選磁間距為4毫米，磁場選擇開關置“強磁場”位置，激磁電流為2安培時****磁場強度不小于14000奧斯特（1110RA/m）。

It is composed of fixed magnetic pole, roller rotation magnetic pole, as well as exciting winding and exciting DC power supply installed above them. The upper and lower magnetic poles are parallel arranged. Two rollers with the diameter of 120mm and the lower magnetic poles constitute closed magnetic circuit. The working distance between the two magnetic poles can be adjusted through the increase or decrease of base plates. Through the adjustment of the voltage of high-voltage machine, the DC current supplied to fixed exciting winding and supplied through electric brush to exciting winding for rollers to rotate magnetic pole can be increased to the rated value 2A smoothly. To meet the requirement for the separation of different types of ore, the magnetic field of this machine can be divided into high-intensity magnetic field and low-intensity magnetic field according to intensity, which can be selected through the magnetic field selection switch on the panel. When the separation magnet distance is 4mm, the magnetic field selection switch is put in the position of “high-intensity magnetic field”. When the excitation current is 2A, the maximum magnetic-field intensity is not lower than 14,000Oe (1,110RA/m).

2、傳動機構：

2. Transmission Mechanism

直流電機經蝸輪減速機減速，傳動輥子旋轉磁極，旋轉磁極的轉速為55轉/分，為了減小電機的體積，采用直流電機用硅元件半波整流供電。

After the working speed of DC motor is reduced through the worm reducer, the motor drives the roller to turn the magnetic pole. The rotating speed of the magnetic pole is 55 R/min. To reduce the size of motor, thyristor half-wave rectification current for DC motor can be adopted for power supply.

3、給礦系統

3. Feeding System

由電磁振動給礦器，儲礦漏斗和給礦錐體及擋板所組成。

The feeding system consists of electromagnetic vibration feeder, storage hopper, feeding cone, and baffle.

電磁振動給礦器可以通過調節面板上左右二個線繞電位器，以控制電磁振動給礦器的振幅，以適應不同礦粒的需要。

The electromagnetic vibration feeder can adjust the two wire-wound potential meters (one is on the left and the other is on the right) on the adjusting panel to control the vibration amplitude of electromagnetic vibration feeder, for ores of different granular sizes.

為了調節給礦速度，可以選用具有不同大小給礦口的給礦錐體即可實現。

To regulate the feeding speed, feeding cones with mouths of different sizes can be selected.

正常給礦時，擋板調至約45度的傾斜度，以便使礦流均勻分散至給礦槽內。若中途需停止給礦，將擋板提至水平靠近給礦口時，即可停止給礦。

During normal feeding, adjust the position of baffle to keep it at a tilting angle of about 45°with the ore so that the ore current can be evenly dispersed in the feed chute. If feeding needs to be suspended, raise the baffle until it gets close to the feeding mouth horizontally.

4、產品清掃收集部分：

4. Product Cleaning and Collection Part

由產品接收溜槽，分離板，重錘清掃刷和盛礦容器所組成。

This part consists of receiving chute, separating plate, counter weight brush cleaner, and ore containers.

在產品接收槽的中部，有一分離隔板，被吸引于輥子上的磁性產物，經隔板順溜礦槽排入磁性產物盛礦容器中，分離隔板的傾斜度可通過擰動槽一側的手柄即可調節，非磁性產物經下部溜礦槽非入另一盛礦容器中。

There is a separating plate in the center of the receiving chute. The magnetic materials absorbed on the rollers are discharged into the ore container of magnetic materials through the separating plate along the chute. The gradient of the separating plate can be adjusted through pulling of the handle at one side of the chute. The non-magnetic materials flow into another ore container after passing the lower chute.
