Great Changes in Technology of Conveyor Belt

With the development of scale of mine, belt conveyor has kept on towards large scale and presents features of large capacity and long distance. Belt conveyor with long distance and multi power has achieve successful research and development, it changes the single load-carrying way that is given by rollers and adopts multi point electric drive. This method can address the traditional problems that are changing conveyor belts frequently and belt breakdown easily. Also, the successful development of this kind of belt conveyor can reduce the cost of equipment greatly. What’s more, its advantages are reducing the number of transshipment or fall of ore during operation and avoiding environmental pollution.

The successful development of belt conveyor with 1km-100km belt length, adopting multi point electric drive which can reduce 10%-30% investment and operation cost. Especially, it can decrease belt strength and eliminate risk of tape break of upward transport belt conveyor with large angle and long distance. And then it can prolong the lifespan of belt more than 5 times. Multi-power belt conveyor not only can achieve the goal of lower investment, lower consumption and resistance, but also operate stably more than 10 years. In this way can it improve the running rate and economic benefit greatly.

What problems will be in the material lifting process of bucket elevator?

In the material lifting process of bucket elevator, there may be such problems: insufficient material lifting rate, insufficient material discharging rate and material leakage phenomenon, only they are resolved timely ,the bucket elevator can have best effects .The reasons and solutions are as follows: 
(1) insufficient lifting rate:
The material is likely to be caked on the bucket or chute, clean and remove the materials regularly according to caking condition. There is also possibility that the storage capacity of bucket elevator upstream equipment is insufficient which causes less feeding material, as result, the bucket elevator can not reach the design capacity, so we should try to improve the production capacity of upstream equipment. If the speed is slow, we have to change the speed ratio of the sprocket. Or it is caused by improper or wrong material calculation, check the calculator and material proportion, calculate again.
(2) insufficient material discharging rate:
The capacity of bucket elevator downstream equipment is small, make the discharge chute block, so we should improve the capacity of the downstream equipment of bucket elevator. It may also cause by small chute size or inappropriate chute angle ,so adjust the discharging chute. There is also a possibility that the material is caked on the chain bucket or inside the chute, so we need to remove material and maintain the bucket elevator periodically.
(3) material leakage phenomenon:
If the material leaks from the gap of head section and bottom section, please add the sealing gasket or glue with sealant . Replace new sealing gasket ,glue with sealant and tight the flange bolts if there gasket of bucket elevator flange is broken. If it is caused by large material feeding height difference and feeding pressure, please change the material feeding method and add the feeding buffer device.
