Vibrating feeder MF series

The operating principle of the RF and MF models Electromechanical Feeders is based on a subresonant system of two masses that are elastically connected. One of them, the moving mass, is the trough itself (1). The other, the fixed mass, is a strong cast part (2), housing a shaft supported on sturdy bearings, the shaft being rotated by a conventional electric motor (3). The shaft is eccentric in the RF model, and concentric with adjustable counterweights in the MF model. The two masses are connected by rubber polymer springs (4). This sub-resonant operation provides the advantages of less installed power and rapid and smooth starting and stoping The Electromechanical Feeders, type RF and MF, can be optionally equipped with Controller, which provides feed rate regulation by acting on the revolution rate of the motor and this varying the speed at which material on the trough moves foward. Other regulation possibilities include: Two speed flow control, by means of an external signal; automatic flow rate control by means of a DC signal; automatic flow regulation in response to the current drain of a motor (crusher).
