It requires that the machine should be tested when users buy it. It is a very important basis to test the operation situation of equipment, so users quite attach the importance to it. As a kind of basic crushing equipment, jaw crusher is used widely in mining market. Its quality has a direct influence on the quality of finished products and crushing efficiency. So, what are the aspects that need to be focused when purchasing and test running jaw crusher? Here, Hongxing will introduce it to you.
There is no doubt that jaw crusher need to be tested according to operation requirements. However, test running is not equal to actual operation, because it is running empty with no materials, and the running time is short. Now, we will introduce the detailed points when test running.
1. Start up and close off jaw crusher according to the start procedure, and all the related chain systems need to meet technical requirements.
2. Let the movable cone rotate at forward or reverse, and it can not exceed 15 revolutions per minute.
3. Ensure that there is no impact and periodic noise.
4. Ensure the normal work of lubrication system. The oil pressure should be controlled in 0.5~1.5 kg/cm2, and returning oil temperature should not exceed 50°C (loaded test must not exceed 60°C).
In addition to meeting the above basic requirements, the jaw crusher should be tested empty and with a load. Only in these two cases can the equipment operate normally, and finally the equipment can be judged to be able to operate and produce normally.
The machine cannot leave factory until it satisfies the above essential conditions. Users usually require test running again when buying jaw crusher in order to ensure that it is normal at the time of handover. This is responsible for not only the company itself, but also the users.
Hongxing recommends that users had better to choose a large manufacturers with good reputation and quality guaranteed to buy the equipment, which can not only ensure the quality of the equipment, but also avoid a lot of troubles.
