Product Description

2500mm hotplyingwiderubberextruderproduction line

The 2500mm double system extruder is the widest and most automated extruder in the world.The pin cold feed rubber extruder applied in the line is high yield, good quality, high efficiency, energy saving and with new-style roller head that can be produce many types of rubber sheet with the max width 2500mm,the thickness 0.6-15mm directly.The line is to instead of calendaring and extruding.calendaring, because the extruding line can settle the problem of air bubble that ever existed, also it can reduce the equipments investment and the energy consumption. The extrusive production process delivers very positive thermoplastic, airtightness and compactness outcomes. The technology of hot plying directly is the most advanced extrusion molding equipment in the world.

Anti-Tearing Conveyor Belting
 

Include the full paragraph-Anti-tearing conveyor belting is widely used in coal mines, iron ore mines,metallurgy.power plants etc, especially in areas where the belt is subject to harsh working conditions, abusive materials and at risk of longitudinal tearing.

One or two layers of the anti-tearing material is added between the cover rubber and the carcass of the belt, to reduce the risk of
longitudinal tearing and increasing the belt life.

In addition to increasing belt ife the Anti-tearing material has the advantage of high tensile strength, low elongation, great impact
resistance,antifatigue and good flexibility.

Anti-tearing material is suitable for use in both steel cord and textile reinforced fabric conveyor belting applications.

For these tvpe of aoplications, strong consideration should also be given to adopting  Extra Tough anti-tearing and impact-resistant cover rubber.

 Easy Running Low Rolling Resistant (LRR) Conveyor Belting

Characteristics and Applications for Easy Running  compound
Using specialized pulley cover compounds, It has developed the Easy Running compound to reduce power demand. Easy Running compound reduces the compression between the conveyor belting and idlers, which results in a reduction of energy consumption of the conveyor belting system.

Easy Running compound is recommended for use for in a wide variety of material handling applications, including long-distance,heavy-duty overland conveyor systems. Significant savings are able to be generated over the life of the belt.

cooperation with domestic and overseas academic organizations, including field studies of long distance conveyor systems. Testing on  Easy Running compound has confirmed savings of greater than 15 % in power resistance.

FAQ

 

Trouble Shooting

No.	Problem	Reason	Solution
1	Conveyor belt runs on one side of the conveyor.	Idlers or pulleys are out-of-square with the center of the belt	Re-adjus the idlers or pulleys in the affected areas
		Sticking idlers	Improve maintenance o rlubrication
		Structurenot level	Readjust the structure in affected area  to make it level
2	Belt Slippage.	Traction force between belt and pulleys isn't enough	Increase pulleys pads area or install belt cleaning device
		Lagging on pulleys is worn or damaged	Change the pulleys
		Bob-weight is too light	Increase the Counterweight level in accordance with the conveyor calculations
3	Conveyor Belting is stretching excessively.	Tension is high	Increase the belt speed or reduce the traffic amount;reduce the friction and replace the damaged idlers
		Belt stretch excessively by wrong installation of the belt	Adopt the mechanized clamping device for the belt
		Distance of bob-weight is not enough	Refer to the belt selection manual to obtain the correct minimum length of the Counterweight
4	Top cover of the belt wear down excessively.	Quality of the cover rubber is too bad	Change the high quality cover belt
		Load bias the center line of the belt	Readjust the blowpit to make the load on the center of the belt
		Overrelaxation between the idlers	Increase the tension or reduce the span
5	Bottom rubber of the belt wear down excessively.	Slipping at the pulleys	Fastening pulleys or increase the contact area of the pad
		Materials deposit between the belt and idlers	Install the cleaning device at the return side of the idlers tail
		Traffic Idlers incline forward excessively	Reduce the angle of inclination
6	Covers harden or crack.	Damage of the heat or chemistry	Choose the belts with special parameters
		Wrong storage or handling	Refer to the belt instructions
7	Cover swells in spots of the belt	Idlers are lubricated excessively to make the oil overflow	Improve the maintenance to reduce the oil number.
8	Vulcanized splice separation	Tension is too high	Improve the belt speed or reduce the traffic amount;reduce the friction and replace the damaged idlers
		Idlers are too small	Use the morebigger diameter idlers
		Wrong installation of  the belt splice	Adopt the correct method of splicing
