We first need to consider when buying paper mill is a problem, I bought this product can use how long. I think a lot of customers are considering this problem, because this involves the cost of the product, a service life long machinery in virtually can reduce production cost, in fact it is not easy to answer this question, because the production of paper mill products materials, design concept, nature is not the same. 

  As an example, a device has three parts, use the longest parts for 3 years, replacing the parts cost 10000 yuan, the other parts are made with deadline for 1 year, every time a replacement cost is 5000 yuan, the equipment purchase price of a total of 30000, our own see whether it is for the most part can not be more than a few times did not cost-effective. But in principle, the life span of the paper machine is defined like this: as long as there was a problem in paper mill in which parts, repair or replace the parts, can continue to use paper mill, is infinitely long service life. But up from cost accounting calculation, it is not so. Should be used according to the longest or most expensive parts of replacement cost to measure the life of paper tube machine.

  In fact the length of the service life of the goods, fundamentally speaking, depends on the quality of the goods. If the goods quality assured, president of natural life.
