Quality of China Conveyor Component

Posted in: , on 9. Oct. 2008 - 14:02

Dear all,

Does anyone have any experience with getting conveyor components manufactured in China.

Are there large competent companies in China capable of manufacturing pullies, idlers, belts etc to the same quality as those manufactured by companies such as Sandvik in Australia.

Has anyone had good or bad experinces in obtaining materials handling equipment.

Best Regards, Gareth Blakey

Well blown me down! I have a 42" LCD TV, a 22" monitor, a 19" monitor (both connected to a dual core CPU to which the printer/fax/copier gadget is also connected). I have a bicycle, shaver, hi-fi, laptop & cable TV box all working well since they left China. Only my Honda was made in Japan and that is going to be still running strong when the oil runs out! What's the fuss with anything so unsophisticated as conveyor hardware? It's not rocket science is it?

I appreciate that the local manufacturers & their occidental principals cannot meet the possible demands of the erratic WA minerals business but what's your choice? Buy from a country who have just put a man in outer space (that is rocket science) or wait around to see which western outfit will be around this time next year?

It is up to the purchaser to specify what is wanted & agree on inspection/quality levels.

I have no experience of Sandvick deliveries but I have had experience of other Australian manufacturers & been pleasantly appalled.

Overlands -Power Hogs Vs Efficient Rubber Performance

Not rocket science? I hope our competition continues to think so.

I believe China has modern technology in belt, idler, and pulley mfg. They may well have similar capabilities in motors, reducers, and VFD's.

Some of China's belt mfgs. are among the best in the world when they are evaluated by their modern machinery and their ability to produce at advanced specifications. Rubber compounds are also being raised to the highest technical level. Many of the world's steel cord belts are using China's supply. Modern trough and pipe belts are at world standards. Still the engineer must know the details.

Rocket Science:

We just finished doing a belt evaluation where manufacturer (mfgr 1) was able to deliver >2800t/h and is limited by the belt x-sectional capacity. Mfgr 1 has been running for about 10 years.

A new belt, from mfgr 2, was then installed that can only deliver 2200 t/h. The 2200 t/h capacity is limited by the motor power (1260 kW).

CDI designed the original belt and approved Mfgr 1 to meet our minimum power draw criteria. We left some power in reserve. Others have upgraded the capacity to use all available power to reach 2800 t/h level.

Before the Mfgr 2 belt was selected, the client was informed not to use a Power Hog belt. Mfgr 2 stated they would supply a low rolling resistance (LRR) compound. We were not informed of the belt properties.

Multiple belt samples were sent for our analysis. The rheology of the mfgr 1 has a predicted capacity of about 2800 t/h at coldest belt temperature and can do about 3000 t/h at normal operating temperatures, but is limited by belt area capacity. The "new" belt, from mfgr 2, is limited by power to 2200 t/h just as the field measurements show. Both theory and practice are in agreement for both belts.

CDI recommended an even better belt which could achieve 3500 t/h for the same belt dimensions, operating condition, and not max-out the installed motor size. The client apparently did not believe our predictions.

Now we see Rocket Science does matter.

Ha Ha designer.

Sorry to have offended you

louispanjang. I have the same problems with Australian manfuatures as well.

As I do not know the companies in China I was asking the wider audience for there experinces.

Thanks for your information Larry.

Hallo Gareth,

I understand your underlying aim this way: You're looking for some reputable manufacturers to check them against your budgets.

My professional background is rather heavy machinery (bulk transport) and not mass articles like idlers and similar.

--- This here is my personal opinion. ---

First you weigh your needs:

If you need sound sleep you go to the next chinese trades consulate man, to an established trades agent or you buy from an established enterprise (even "western world"). Is there anyone out there who does not manufacture in the Mainland? You'll have some of the benefits + your needs for quality etc. will be met at your standard.

If you need a bit of adventure, you try to get a professional stay for longer than 30 days and find an enterprise in the Mainland, that does not yet manufacture for someone important or has spare capacity. I personally don't know anyone who has such a knowledge without making a use of it. After you understood all the fine details of local trades agreement legislation, (legal) language and local culture you make it absolutely clear that your order will not be subcontracted to "someone". Be sure to inspect the workshop regularly when your order is on the way.

I stop at this and hope you see a bit of my way.

At this place I feel you'd really appreciate the input of our chinese collegues?!

Or maybe you put your request straight to the "new projects" - forum?

Best regards

Products From China

Posted on 13. Dec. 2008 - 05:33

Any country, be it advanced, advancing or yet to advance( some call it backward) have three categories of manufacturers/suppliers.

Good /better / best or seen from different angle- bad/worse/worst.

No one is an exception, I repeat NO ONE.

With China- you should remember few things-

1. Who will inspect the products you are going to buy?? while manufacturing and while geting it packed.

2. Who ever makes it, while stuffing there is some sort of malfunction and you end with wrong supplies!!! So who will stand next to the container while it is stuffed.

Both taken care, you can select any of the three and be happy / hanged.

Cheers

I just recently visited a large manufacturing plant in China where they implemented ISO 9000 procedures and prudent quality control.

Large turnkey international conveyor suppliers are purchasing from these factories. I would recommend and do the same.

This endorsement does not eliminate the risk of not doing do dilegence. No doubt there are good and bad suppliers. Do your own study.

Much truth!

ISO 9000 is a paperchase that does not guarantee anything. ALWAYS do your own inspection.

hi,

I have few experiences like

1. All the components they manufacture are not to international standard

2. They maintain there own standards for repeat orders with poor quality

3. The reason they sell at less rate is coz of poor quality and their own standards

4. we brought two stackers from china and now we are encountering wiith many problems

5. It is only my experience donot take it as standards
