FH heavy vibrating feeder

FH heavy vibrating feeder

FH feeder is a new type of high-efficient vibrating feeder which is based on the experience of design, production, sales and service of mining industry for many years. We absorbs the most advanced design concept from abroad, develop and design it independently. In the production line it could feed the crushing machines continuously and finish the coarse screening of the raw material. This equipment can be widely used in crushing、screening equipment in metallurgy, coal, mining, construction, chemicals, grinding  industries, etc.

Output size : 600-1300mm

Production capacity : 350-1600 T/H



All kinds of mineral stone, except viscous materail



Widely used in metallurgy, coal, mining, construction, chemicals, grinding industries, etc.



1. Large feeding capacity, high screening efficiency. Using advanced design concepts and manufacturing processes, the capacity of FH vibrating feeder is 1.5 times of the traditional feeder.

2. Easy to adjust and control, with a wide using range. FH vibrating feeder uses Y3 series motor with high efficiency and energy saving. And it could be equipped with variable frequency controller to achieve precise adjustment, to meet the needs of different material feeding and screening.

3. The excitation design Eccentric shaft and eccentric block makes it easy to adjust the amplitude.

4. Greater vibration intensity brings the larger feeder throughput, higher screening efficiency and larger processing capacity.

Working principle:

The vibrator of FH Vibrating Feeder can produce directional excitation force through the eccentric shaft and eccentric block. There’s a pair of gear with the ratio 1 connected between the two shafts to ensure that the opposite direction of rotation and same speed. By the motor driving, the eccentric shaft rotates. Due to the eccentric mass on both axes and eccentricity are equal, the resulting inertial force cancel each other in one direction, and superposition in the other direction so that could compound the directional excitation force.

And then feeder body which is rigidly connected with the exciter forcibly vibrates on the supporting spring.The material slides and throws on the trough under the action of the vibration force and is moved forward for feeding. When the material goes through the groove on the grate, the smaller gravels go through the gap between the grate fell, go to the next crushing process directly without crushing, which play a pre-screening effect. That could fully guarantee the efficiency and capacity of the broken crushing equipment.
