The vibrating feeder in the mine is used to uniformly or quantitatively provide the materials from the storage silo or other material storage equipment to the feeding equipment; it is the necessary automation equipment in the practice routine operation.

Classification of feeding machine:

Feeder has two kinds: open and closed types, according to the requirements to produce the electromagnetic vibrating feeder, hopper, and belt conveyor.

The vibrating feeder structure is simple and easy to operate without moist, small power consumption; evenly adjust the amount of ore; therefore it has been widely used.

The vibrating feeder Uses:

Widely used in mining, gravel field, metallurgy, building materials, chemical industry, mineral processing, coal mining and other industries' crushing and screening production line.

Vibrating feeder working principle: The machine utilizes eccentric block rotation and produces the centrifugal force, making vibrator sieve compartment, vibrators and other movable parts for mandatory continuous circular or approximately circular movement. Material with sieve compartment in the tilt of the screen surface does the continuous throwing motion and continuously and uniformly sends the material to the discharge port.

Installation and commission:

a. When the feeder is used to batching and dosing, in order to ensure feeding is uniform and stable, preventing material from artesian installation horizontally.
b. Feeder after Installation should be left a 20mm swimming gap, lateral should be level; the suspending device adopts flexible connection.
c. Feed during operation should always check the stability of the amplitude of the current and noise, when abnormal situations became should be parked timely and process.

Feeder safety procedures:

1. A feeder should be installed on a fixed basis.

2. Before the use of feeder, it must inspect various moving parts, if the tape hasp and carrying device is normal, protective equipment is complete.
3. The belt feeder should load to start. And then operate normally before feeding. First feeding after car is prohibited.

The Technical Innovation of China Vibrating Feeder

Hongxing Machinery summarizes the main technical innovation of China vibrating feeder, which are listed in the following:
(1) Improve the performance and reliability of the spare parts and reduce the maintenance amount. The operating rate of the equipment is mainly determined by the performance and reliability of the spare parts, for this reason, the development and application of new technology and new products of vibration feeder remains an issue worthy emphasis. For example, high-performance controllable soft-start technology, dynamic analysis and monitoring technology will further improve the performance of the feeder machine. The adoption of new materials and new technology, especially high-performance materials, needs further research to reduce the weight of the vibrating machine and improve its product quality. Adopting non-metallic spare parts, such as rubber spring, compound spring and glass plate spring, greatly improves the running stability of the vibrating machine.

(2) Vibrating feeder is likely to develop towards large size, but in a time period, we should focus on the research and development of vibratory feeder with novel structure and good stress condition and break through the traditional design pattern in vibrating feeder structure. The needs of economic development will force people to research and manufacture large-sized vibrating feeder to improve the processing capacity and adapt to the need of intensive production with high yield and high efficiency. However, the development of large-sized vibrating feeder needs further exploration in structure strength to improve its running reliability.

(3) Develop towards standardization and serialization, which is the means to facilitate design, organize professional production, ensure quality and reduce cost. Developing towards high efficiency and high yield is necessary, and the modern process of industry promotes the companies to increase the scale and improve the production capacity, which needs vibrating feeder with high efficiency and high yield to match. For this reason, the companies are forced to develop professional vibrating feeder to match other machines to satisfy the production requirement.

(4) Constantly improve the adjustment and control performance of vibrating feeder to maintain highly efficiency working state. The angle of the trough can be adjusted to meet the requirement of processing capacity, and the adjustable vibrating pattern is to adapt to the requirement of different materials and feeding efficiency.

(5) Reduce power consumption and noises can protect the environment and is humanization design.

Vibrating feeder is also called grizzly feeder, chute feeder and mining feeder. Vibratory feeder is generally used in stone production line to pass large blocks of stones on to jaw crusher. Feeder machine can transport massive and granular materials to receiving machine evenly and quantificationally, so mechanical feeder is widely used in sand production line.

Vibration feeder generates centrifugal force by the rotating eccentric block, and then force cabinet to vibrate. The materials in the cabinet move towards until arrive at the mouth of receiving machine as vibrating.

The characteristics of feeder machine;

The vibrating grizzly feeder is designed for transporting large-scale materials. Adopting double eccentric shaft vibration exciter guarantees the transportation of large pieces of stone.

Evenly and quantificationally feeding guarantees that receiving machine will not pass its operation load, and avoid that the receiving device will not be locked dead. The grate structure of trunk can coarse screen materials and improve screening effect.
