Used Jaw Crushers – Can It Be A Constructive Investment?
Are used jaw crushers a good option?
A jaw crusher may be very handy in the daily operation of your business. To put it simply the machine crushes materials to a finer and more desirable consistency. It all depends on what your requirements are.
If you feel that a new crusher is too expensive then there is always the alternative to buy a used model. Brand new jaw crushers can be quite expensive.
But before you buy the first machine on offer there are some things which you should look at and take into consideration before you make your final decision.
The seller should supply you with a service record indicating when the machine was serviced.
Depending on your needs, you do not want to use a machine that had to crush the toughest material out there when your requirements are for example the crushing of soft limestone.
When a crusher has some sort of crack it usually gets fixed by welding it. So inspect the frame very closely and ask about anything you are uncertain of. When looking at this it will give you a very good indication of how roughly the machine was operated and used.
Next look at the fly wheel, is it in good condition or are there cracks giving away a badly maintained machine. See if there was any welding done and decide in what condition it is.
Another important thing is to inspect if the gap between the jaw plates and the sides are the same. If it is not, that might be an indication of a failure or excessive wear inside the eccentric housing.
Are you able to turn the flywheel by hand so that it makes no noise and runs smoothly? If this is not the case then it could indicate a worn out shaft or perhaps a bearing failure.
How worn are the grooves on the flywheel?
Take a look at both the cheek and the jaw plates, are they worn out? If so it is not very good.
It is always advisable to be prepared and to make an informed decision when one needs to make an investment in ones business. Ask questions and be sure they are answered to your satisfaction. You do not want to invest a substantial sum of money into a machine that does not work properly. Thus one should look at the overall condition of the machine.
