A vibrating feeder is a type of equipment that uses vibration to “feed” or transport materials from one process step to the next. Vibrating feeders can be used to transport bulk or granular materials from storage to crushers, conveyors, and other processing machines. They are used in industries such as mining, metallurgy, coal, construction, chemical, and food processing. The design of vibrating feeders is such that they are maintenance-free and perform reliably even under the most demanding conditions. They are designed to provide a uniform and continuous flow of materials, making the downstream equipment more efficient and effective.
The Vibrating Feeder is mainly used to feed material into the primary crusher homogeneously and continuously, while screening the material, making the crusher more efficient. Our Vibrating Feeders are proven performers and require no maintenance, making them the first choice for the most demanding applications, including public utilities, mining, metal production, food processing, cement, and other industries.
The working principle of a stone vibrating feeder is relatively simple. The vibrating feeder uses the eccentric mass in the vibrator to generate centrifugal force, so that the moving part of the equipment (the cone-shaped hopper) performs forced continuous circular or approximately elliptical motion. The materials in the hopper are thrown up and move forward in a straight line when the vibration frequency is the same as the natural frequency of the hopper. At the same time, the materials are screened through the sieve, and materials with particle sizes smaller than the gap of the sieve are discharged from the lower part of the sieve to achieve the purpose of feeding and screening materials. The vibrating feeder is widely used in mining, building materials, silicate, and chemical industries for crushing and screening equipment.
