Grizzly Feeder

Vibrating grizzly feeder is a kind of linear direction feeding equipment. The vibrating grizzly feeder is widely used to match the crushing and sieving equipments in many industries including metallurgy, coal mine, mineral dressing, building material, chemical, grinding, etc. The Vibrating Feeder has been used to transfer the large size materials and granular materials from hopper to receiving device uniformly, periodically and continuously in the production flow and to feed materials into the crusher continuously and uniformly also to screen the materials in the sandstone production line.

WORKING PRINCIPLE:

Vibrating feeder consists of vibrating frame, spring, vibrator, motor vibrating device and motor. The vibrator is made of two eccentric shafts rotating at high speed at the same time from opposite directions, thus the strong centrifugal force is formed.

When installation, the two gears must be jogged according to the sign. Through drive of the motor, the two eccentric shafts start rotating to produce a linear huge power which forces the feeder to vibrate. Through the vibration, The materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller parts will fall down, avoiding the further crushing, so screening purpose can be reached. Vibrating feeder can be used in these areas such as metallurgical industry, coal mining industry, mining-selecting, building, chemical and grinding industry, etc.

VIBRATING FEEDER FEATURES:

• Vibration motor is vibration source, low noise, power consumption, well adjustment performance, no material collision phenomenon
• It can adjust the exciting force, control and change the flow at any time, convenient adjustment and stability
• Vibration stable, working reliable, long life
• Simple structure, reliable, easy installation and adjustment, light weight, small size, easy maintenance
• Small amplitude, high frequency and large obliquity
• Used eccentric block to produce strong exciting force
• Flexible connection and stable operation with tire coupling

APPLICATIONS:

Vibrating feeder is used to feed raw materials into the primary crusher continuously. Vibrating feeder is widely used in stone quarrying, aggregate production, sand making, ore beneficiation, coal and cement industry to feed limestone, granite rock, basalt rock, river stone, iron ore, copper ore, feldspar, gold ore, bauxite ore etc. to primary crusher. According to the process capacity of the primary crushing machine and the whole crushing plant, the clients can adjust the feeding capacity flexible.

Vibrating feeder is a kind of equipment mainly used for quantitative and continuous conveying of materials. Its working principle is to vibrate the silo and the material through the excitation of the vibration exciter, so as to transport the material out. Specifically, the vibrating feeder is composed of several parts such as a silo, an exciter, and a conveying roller. The silo is used to store materials, usually made of steel plates and steel pipes and other materials, and has a certain bearing capacity and sealing performance. The exciter is the core component of the vibrating feeder, which converts the energy generated by the machine into the vibration energy of the silo through electric motors or pneumatic devices. Conveyor rollers are mainly used to support and transport materials.

During the operation of the vibrating feeder, the motor or pneumatic device will generate vibrations corresponding to the frequency and amplitude, which will be transmitted to the silo through the exciter. The frequency and amplitude of silo vibration depend on the parameter settings of the actuator and the characteristics of the material. When vibration occurs, the material will also vibrate accordingly. In the silo, the material is constantly bouncing, rolling and flowing due to repulsive forces. Through the conveying roller under the silo, the material can be conveyed smoothly.

By changing the vibration frequency and amplitude of the actuator, the conveying speed and flow of materials can be easily controlled. In addition, the vibrating feeder can further adjust the conveying effect by adjusting the feeding amount and the pressure of the silo. Whether it is powdery material, granular material or lumpy material, it can be smoothly conveyed out by the vibrating feeder.

In short, the working principle of the vibrating feeder is to use the vibration energy generated by the exciter to make the silo vibrate at a certain frequency and amplitude, so that the material can be conveyed smoothly. It has the advantages of simple structure, high conveying precision and good continuity, and is an ideal equipment in various material conveying systems.
