Working principle
The material enters the trough of the feeding roll from top and is brought to the material outlet through a rotary roll and an adjusting plate, therefore, the feeding is continuous and uniform. A plate magnetic separator is mounted near the material outlet and can remove iron impurity from materials.
The feeding amount can be automatically adjusted. The control principle is as follows: A sensor detects the working current of the grinding machine real time, and transmits the signals to the controller of frequency conversion motor of the feeder, and then adjust the opening of the adjusting plate and the rotating speed of the frequency conversion motor through comparison with set current, so as to automatically control the feeding amount.
Installation procedures, methods and attention points
For installing the principal machine of the feeder, flanges are all used for jointing the upper inlet with the gate and the lower outlet with the hammer mill. A soft connection is recommended and the machine body should be kept horizontal. After installation, the feeding roll should be checked whether it rotates in the box body flexibly without any hindrance.
It is recommended to hang the controller onto the wall in the power distribution room for the grinding machine, and the screen is about 1.6m apart from the ground, for the convenience of operation and maintenance.
The current transformer delivered together with the controller should be mounted in the power distribution cabinet for the grinding machinery, and any one of power lines L1, L2 or L3 for the grinding machine should pass through the mutual inducting coil.
