circularvibratingscreen | Vibrating screen application in mining

Each kind of vibrating screen workload is heavy in mining and other industries. In the process of coal and steel production, every material processing capacity is over gigaton, and mineral processing volume reached billions of tons, handling and processing flows using the feeding, transport and screen vibrating equipment a lot.

The vibrating feeder, vibrating screen and other screening equipment will be widely adopted in every part of coal producing and handling system, coal preparation plant takes a great proportion. The vibrating screen equipment has put a high value at home and abroad because of its important position in national economy. Because vibrating screens’ demand is increasing, vibrating screen production has a great development in recent years.

1. Theory and application of new technology

The material motion trajectory is a straight line or a circle when traditional self-synchronization vibrating screen is running. Linear vibrating motor needs two groups’ eccentric block to run synchronously in general, thus generating line reciprocating vibration power. Mandatory synchronous transmission mode is made of two groups eccentric block which has a couple of same diameter and same number of teeth of gear, but two groups eccentric block realized unforced connection lubrication requirements of synchronous gear by using mechanics principle in recently years, and the system is more simplified than before.

2.The development of large vibration equipment

Because of the expansion of the mine, large mining machinery has expended the scale of production; many factories have rolled out new machines.

(1) Large vibrating feeder has already used in mine, which has reduced the feeder line installation, simplified the produce technology, improved production efficiency.

(2) Dewatering vibrating machine is necessary equipment.

3.Machine vibrating parameter strength increases

In order to improve the working efficiency of mine vibrating machine, some company improved the machine vibrating parameter based on perfecting equipment structure strength.

4.The application of new material and new technology

(1) The use of nonmetal damping element, such as rubber recombination spring, spring, etc, thus improved the reliability of vibrating machine running.

(2) The use of ring-grooved lock bolt has improved the structure strength, thereby improved the reliability of equipment running.

The development of vibrating screen plays an very important role in mining and manufacturing, it is a crucial mission that mining machine and new production is developing and researching.
