vibrating feeder-How it works？What are the types of feeders? 10 Types of Common Feeder Machine

Chute Feeder

Chute feeder is suitable for the ore feeding of medium-sized materials, the maximum particle size can reach 450mm, and the ore feed can be adjusted by adjusting the eccentricity of the eccentric wheel of the transmission mechanism. The width of the trough body of the chute feeder is 2-2.5 times of the maximum particle size of the ore feed, which is mainly used for the feeding of jaw crusher and bulk lime in the preparation of lime milk.

The most common chute feeder size is 980*1240mm, and its feed size is 0-350mm, which is suitable for the feeding equipment of 400*600 jaw crusher.

Pendulum feeder is suitable for short distance transportation and high specific gravity materials with a particle size of 35 – 100mm. Pendulum feeder is not suitable for conveying dry powder materials, otherwise dust pollution and outlet blockage will occur.

Pendulum feeder is mainly used as the feeding equipment of the belt conveyor when collecting ore in the ball mill, and the feed particle size is generally less than 25mm, which belongs to intermittent feeding.

Disk Feeder

Disk feeder is a kind of continuous volume feeding equipment composed of driving device, feeder body, metering belt conveyor and metering device, which makes use of the fluidity of materials. The material is scraped from the container to the receiving equipment through a rotating disc and an adjustable scraper, which is suitable for all kinds of non-viscous and not very good fluidity -20mm fine materials.

Disk feeders are divided into open type and closed type. Generally, the open type is adopted, and the closed type is used only when the content of fine particles of the material is high.

Screw Feeder

Screw feeder can be installed in the lower part of the silo and is suitable for horizontal, vertical or inclined conveying. The material flow is controlled and adjusted uniformly and continuously by changing the spiral speed. The screw feeder is easy to feed non-viscous powdery, granular and small particle materials evenly to the receiving equipment from the silo and other storage equipment.

Screw feeder has the features of conveying, sealing, homogenizing and stirring. It is a common equipment in cement raw meal homogenization and silo sealing feeding. There are many types of screw feeder, such as solid screw, belt screw, variable pitch screw, conical screw and so on.

Impeller Feeder

Impeller feeder is composed of a group of blades installed on the shaft and the outer sealing shell. Driven by the motor, the impeller on the spindle is driven by the reducer to drive the material from the upper silo through the impeller groove to feed out evenly. The feeding capacity is changed by adjusting the speed of the impeller.

Impeller feeder has good tightness, avoids environmental pollution, and is suitable for the transportation of loose non-viscous dry materials and small bulk materials with good fluidity.

Scraper Feeder

Scraper feeder is composed of many scrapers fixed between two chains with a certain distance between them. The scraper moves along the slot bottom, which can be used for horizontal transportation or inclined transportation. When transporting upward along the incline, the inclination of the material layer shall not exceed 25 °, and when transporting downward, the inclination shall not exceed 20 °.

The working principle and traction parts are the same as the scraper conveyor. Scraper feeder can realize closed and multi-point feeding, which is suitable for materials with less powder or granule, grindability and stickiness.

Electromagnetic Vibratory Feeder

Electromagnetic vibratory feeder uses the electromagnetic vibratory exciter as the vibration source to drive the hopper, which has the features of small amplitude, high frequency, slow conveying speed. Electromagnetic vibratory feeder is a new type of quantitative feeding equipment, which can meet the requirements of continuous production.

The maximum ore feeding particle size of electromagnetic vibratory feedercan reach 500mm, it is widely used for ore feeding of medium and fine crushing equipment and screening equipment, ore discharge of ore bin, etc.

The following factors must be taken into account when choosing a suitable feeder machine:

• 1. The feeder machine capacity should be matched with the system, and the purchase cost, operation cost and maintenance cost are reasonable.
• 2. The feeder machine is reliable and durable, the operation is stable, and the probability of sudden failure in work is little.
• 3. The service life of the parts of the feeder machine is long, so the maintenance times and equipment shutdown period should be reduced maximumly.
• 4. For auxiliary equipment, the procedures of standardization and serialization of spare parts should be high, versatility and interchangeability should be strong, and the metering unit and voltage level should meet the prescribed requirements.
• 5. The performance, structure, external dimension, quality and strength of the feeder machine are suitable for the plants.
• 6. The protection level of the feeder should meet the provisions of the safety regulations, and should be safe to use and maintain.
