NG型周边传动浓缩机  NG Peripheral Drive Type Concentration Machine

NG型浓缩机为辊轮式周边传动浓缩机，大型浓缩机一般采用此类周边传动，过载时辊轮打滑，不需要特别安全装置，池子一般为混凝土结构。为了给电机充电，在中心支柱.上装有环形接点，而沿环滑动的集电接点则与耙架连接，并由敷设在耙架.上的电缆将电流从这些接点引入电机。

The NG concentration machine is a roller- based peripheral drive type concentration machine. The peripheral drive is generaly used in large concentration machines. The roller slides under overload and no special safety device is required. The tank is generally made of concrete. The central column is equipped with a ring node to charge the motor. The collector contact with a ring slide is connected to the rake bracket. The current is led through the cable on the rake bracket from the contacts to motor.
