Crusher Discharge Port Detection

The discharging detection of a coal mill is one of the contents about dressing test technology. The purpose of this test is to adjust the size of the discharging port, so that we can control the size of the crushed product efficiently and balance the load of various parts of the crusher reasonably. Normally there are two methods to detect the discharging port as the direct method and the indirect method.The direct one is the most common and most simple method. It is that throw a shot into the crusher and then measure the size of the diacharged shot which is squeezed in the crusher to identify the size of the discharging port. The indirect method includs general hydraulic test and inductance hydraulic test.The general hydraulic test is setting a rod over the hydraulic oil level indicator of the discharging. The oil level actually reflects the position of the moving cone of crusher and show the size of the discharging port directly.The inductance hydraulic test rely on the electronic control system of electric hydraulic control device. What is to say that the inductive clearance measurement device under the spindle or the transmittingselsyn upon the shaft will automatic measure and display the position of the spindle and the size of the mouth. Inductance hydraulic test is able to detect instantaneous size of the discharging port continuously. So that adjust the port immediately and realize automatic of the operation. But this method could only be used by crushers with hydraulic governing system of the discharging pot and electric hydraulic control system,It is mainly in the cone crusher.impact breaker: http://www.fote-machine.com/product/impact-crusher.html
