(一)新型振动给矿机的给矿原理和制造安装新型振动给矿机的给矿原理是利用安装在给矿斗上三相交流(380伏)振动电动机使给矿斗上下运动和前后移动,振动电动机的转子两端带有偏心轮或偏心块,电动机与给矿斗固定为一体,当电动机旋转时,由于偏心块的离心力作用和给矿斗的倾斜度,使给矿斗产生振动力,斗内矿石在振动力作用下从斗内排出,完成给矿过程。泗顶铅锌矿选矿厂给矿机原是MC1080型800×2200毫米的链板式给矿机。矿石块度为300毫米左右,矿石比重为3.03吨/米~3,假比重为1.75吨╱米~3,普氏硬度为7。1984年12月,利用年终检修的机会,将原链板给矿机折除,改装为振动给矿机。为使改装的时间最短,消耗的材料最少,我们尽量充分地利用原链板给矿机的基础和原粗矿仓的下料口。采
(A) of the new type of vibration feeder to the ore principle and manufacture and installation of a new type of vibrating feeder to the mining principle is to use to install on the mining bucket on the three-phase AC (380 V) vibration motor to the mine bucket up and down movement and move back and forth , Both ends of the rotor of the vibration motor are provided with eccentric wheels or eccentric blocks, and the motor is fixed integrally with the mining bucket. When the motor rotates, the centrifugal force of the eccentric block and the inclination of the bucket cause vibration to the bucket , Within the bucket of ore under the action of vibration from the bucket discharge to complete the process to the mine. Si Ding lead-zinc ore dressing plant to mine machine was originally MC1080 800 × 2200 mm chain plate feeder. Ore block size of about 300 mm, ore weight 3.03 tons / m ~ 3, the proportion of false 1.75 tons / m ~ 3, Platts hardness of 7. 1984 December, the use of year-end maintenance opportunities, the original chain to the board Miners removed, converted to vibration to mine machine. In order to minimize the modification time, consume the least amount of materials, we try to make full use of the original chain to the basis of the mining machine and the raw coarse ore bin mouth.
