I mine a PY-900 cone crusher, in the past two problems difficult to solve, I mine in 1981 has been improved. It has now been in use for five years and improvement is very successful. Broken mill rolling acetabular wall and adjust the ring between the infusion of zinc alloy, the use of three months or so have to be replaced, you need to stop for a few days, spend thousands of dollars to repair both cumbersome and unsafe. I now mine zinc infusion perfusion, use elastic mat fixed method, safe and easy, material costs just tens of dollars. Crusher fixed disc and the spindle connection was originally designed as a threaded connection, often loose, and even wear off the spindle thread so that the spindle
