The stable feeding system is the starting link of the complete stone processing flow. If raw stones are supplied intermittently or excessively, the jaw crusher will face alternating no-load operation and instantaneous overload, which easily causes vibration fluctuation, motor overload and abnormal wear of wearing parts. The vibrating feeder delivers steady, homogeneous material flow to the primary crushing host at a constant rate, maintaining balanced load of the crusher all the time. It effectively avoids frequent start-stop of the main machine and stabilizes continuous production capacity of the whole crushing and screening plant.
I. Strong Vibration Force Design
This feeding machine is equipped with dual high-power vibration exciters as power source, generating powerful and stable compound vibration force. Even bulk, sticky and wet mineral materials can slide forward smoothly on the feeding tank without arching, bridging or material accumulation. The inclined tank body structure cooperates with strong vibration to break up compacted material piles, thoroughly solving the common blockage problems that easily occur in ordinary feeding equipment, greatly improving overall material conveying efficiency.
II. Adjustable Feeding Speed
The vibrating feeder supports stepless adjustment of vibration frequency and amplitude through frequency conversion control cabinet. Operators can flexibly raise or lower the feeding volume according to the real-time processing capacity of the jaw crusher, matching the feeding rate with crushing efficiency perfectly. When switching different raw material specifications or adjusting target hourly output, simply adjust vibration parameters without replacing any spare parts, bringing flexible overall production scheduling control for aggregate processing plants.
III. Durable Structure for Heavy Duty Use
The feeding tank adopts thickened wear-resistant steel plate integrated welding molding, and the material contact surface can be additionally equipped with replaceable wear-resistant lining plates to extend service life. All vibration bearings adopt fully sealed dust-proof and shock-resistant structures to resist long-term erosion of mineral dust, mud and gravel impact in open-pit mines. The whole machine is designed for 24-hour uninterrupted heavy-load feeding of large lump raw ore, with low failure rate and simple daily maintenance work.
IV. Wide Application in Crushing Lines
Vibrating feeders are standard matching feeding equipment installed in front of all primary crushing stations. It is widely matched with jaw crushers, heavy hammer crushers and mobile crushing stations in quarry aggregate production lines, limestone cement raw material processing plants, construction waste recycling crushing lines and open-pit mine mineral processing projects, serving as the first conveying link of various stone processing workflows.
Driven by the intelligent transformation of mining machinery, new-generation vibrating feeders are integrated with PLC linkage control modules, real-time material level sensors and automatic speed adjustment devices. The feeder can automatically sense the material storage status inside the crusher cavity, intelligently increase or reduce feeding volume without manual operation. Linked with upstream stackers and downstream crushing hosts, it realizes unmanned automatic feeding control, further improving overall automation and operating efficiency of the whole aggregate plant.
Frequently Asked Questions About Vibrating Feeder
Q: What is the core function of vibrating feeder in crushing line?
A: It continuously and uniformly delivers bulk raw ore to primary crusher, keeps balanced feeding volume, prevents crusher overload or idling, and ensures stable continuous production of the whole plant.
Q: How does strong vibration force solve material blockage?
A: Dual powerful exciters generate stable compound vibration to break compacted material piles, eliminate bridging and arching, make sticky, wet bulk materials slide smoothly without blockage.
Q: Can we adjust feeding speed of vibrating feeder?
A: Yes. Equipped with frequency conversion control system, vibration frequency and amplitude can be steplessly adjusted to change feeding capacity to match crusher processing output.
