Special Vibrating Feeder For Coarse Crushing And Pre Screening

The motor vibrating feeder adopts two vibrating motors of the same specification as the excitation source. The excitation force is generated by the eccentric blocks at both ends of the vibrating motors. It is a relatively ideal vibration drive device. The feeding process of the motor vibrating feeder is achieved through reciprocating linear vibration in the inclined direction of the feeding trough. When the component of the vibration acceleration of the tank is greater than the component of the gravitational acceleration in the direction perpendicular to the tank, the material in the tank is thrown up and jumps forward along a parabolic track. Each time the tank vibrates, the material will be thrown up once. In this way, the material continuously jumps forward at the vibration frequency of the tank, achieving the purpose of feeding.

Structural Characteristics

• Smooth vibration;
• Special bar screen equipment can prevent material blockage;
• The gap of the grid bars is adjustable;
• An optional stepless speed regulation motor can be installed, which is convenient for controlling the feeding amount and eliminates the need for frequent motor starting.

Characteristics And Advantages

• Small in size, light in weight, and simple and compact in structure;
• Easy to install and maintain, with low operating costs;
• High efficiency and large feeding capacity;
• Low noise, which is conducive to improving the working environment;
• Low power consumption and high power factor;
• This equipment operates in a state far beyond resonance, thus ensuring stable amplitude, reliable operation, and strong adaptability to various materials.
• After being equipped with a motor speed controller, the feeding amount can be conveniently and steplessly adjusted without the need to adjust the eccentric block.
