What is vibrating screen
Vibrating screen is operated by the reciprocating rotary vibration generated by the vibration of the vibrator.
The rotating hammer of the vibrator causes the plane surface cyclotron vibrating screen surface, while the lower rotating hammer makes the surface of the screen produce cone-shaped rotary vibration, the effect of the combined effect is to produce the complex surface vibration. The vibration trajectory is a complex spatial curve. Adjust the upper and lower rotating hammer excitation force, you can change the amplitude. Adjust the upper and lower hammer of the space phase angle.you can change the screen surface trajectory curve shape and change the screen surface material trajectory.
Main advantages of vibrating screen
vibrating screen with reliable quality, stable performance, low energy consumption, long life and other advantages.
Uses of vibrating screen
The scope of application of vibrating screen is very wide. All aspects of life in the processing and manufacture of supplies need to use various types of vibrating screen.
Vibrating screen is mainly used in mining, coal, smelting, building materials, refractories, light industry, chemical industry, medicine, food and other industries.

Vibrating feeder is also called vibration feeder.Vibrating feeder in the production process, can block, granular material from the storage silo in the uniform, timed, continuous to the receiving device to go.
In the gravel production line for crushing machinery for continuous and uniform feeding, and coarse screening of materials, widely used in metallurgy, coal, mineral processing, building materials, chemicals, abrasives and other industries, crushing, screening and joint equipment.
working principle of vibrating feeder
vibrating feeder is composed of feeding tank body, exciter, spring bearing, transmission device and so on. The vibrating source of the tank vibrating feed is the exciter. The exciter is composed of two eccentric shafts (main and passive) and a gear pair. The motor drives the drive shaft through the V-belt, and then the driven shaft engages the driven shaft Rotation, the main and passive axis at the same time reverse rotation, the tank vibration, the continuous flow of materials to achieve the purpose of conveying m aterials.
Uses of vibrating feeder
Vibration feeder designed for crushing and screening coarse crusher in front of uniform delivery of large pieces of material design.
Vibrating feeder with double eccentric shaft shaker structure to ensure that the equipment can withstand the impact of large pieces of material falling, feeding capacity. In the production process can be massive, granular material from the storage silo in the uniform, timed, continuous feeding device to receive, thereby preventing the receiving device due to uneven feeding and crash phenomenon, extending the equipment Service life.

What is plate feeder?
Plate feeder is generally divided into heavy, medium and light three specifications, is commonly used in concentrator feeding equipment.
plate feederaccording to the transmission method of right-type transmission and left drive, along the direction of material movement, transmission system in the right side of the machine for the right drive, the other for the left drive.
Applications
plate feeder is the mining, metallurgy, building materials, ports, coal and chemical industrial and mining enterprises in the widespread use of a continuous transport machinery.
It is mainly used as a continuous feeding and transporting of heavy and abrasive bulk materials from crusher or hopper to crusher, batching device or transportation equipment.
plate feeder is one of the important and indispensable equipment in ore and raw material processing and continuous production process.
how plate feeder works
A chain of high-strength bulldozer with a pitch of 228.6 mm (9 inches) is used as a tractor.
The two chains are connected to a pair of tension pulleys mounted on the head of the machine body and a pair of tension pulleys Loop, each chain in the two rows of chains are equipped with overlapping, heavy structure of the conveyor trough to become a continuous transport of
materials to the line.
plate feeder weight and the weight of the material from the body mounted on the multi-row support wheel, chain wheel and slide beam support. The transmission system is connected with the reducer by the AC variable frequency speed regulating motor, and then the low speed operation is carried out by the drive unit with the drive unit. The material discharged from the tail silo is transported along the conveying line to the front of the machine body to realize the purpose of continuous and uniform feeding of the working machine to the lower part.

Vibrating conveyor is a king of vibrator to vibrate the trough, so that the tank material in a certain direction of sliding or throwing a continuous conveyor machinery.
The vibrating conveyor uses the motor as the high quality vibration source, causes the material to be tossed at the same time forward movement, achieves the transportation goal;
The structure form divides into the open type, the seal type; The transmission form may the trough transmission or the tube type transportation, the electrical machinery position Can be up, down or side mounted side.
Classification of vibrating conveyor
1.Flexible connecting rod type.
Elastic connecting rod vibration conveyor consists of eccentric shaft, connecting rod, connecting rod end spring and trough and so on. Eccentric shaft rotation to make the end of reciprocating rod movement, causing the tank for directional vibration. So that the material within the tank continue to move forward. Vibration conveyor generally uses low frequency, large amplitude or medium frequency and medium amplitude.
2.Electromagnetic type
Electromagnetic vibrating conveyor by the core, coil, armature and chute and other components. Rectified current through the coil, the cyclical changes in the electromagnetic attraction, stirred tank vibrate. Generally use high frequency, small amplitude.
3.Inertial type
Inertia type by the eccentric block, spindle, chute and other components, eccentric block rotation generated by the centrifugal inertia of the vibration caused by the trough. Medium frequency and amplitude are generally used.
Uses: Widely used in metallurgy, coal, building materials, chemicals, food and other industries in the powder and granular material transport.
Features: This model has the advantages of simple structure, convenient installation and maintenance, low energy consumption, no dust scattering and low noise.
