我矿有一台PYB900标准型圆锥破碎机。在使用中,存在着两个问题难以解决。现在我们已改革成功。一项是原破碎机轧臼壁与调整环、破碎壁与圆锥躯体间灌注的锌合金,只能使用一年左右就得更换,一换就得停产几天,要花上千元的钱,且操作既麻烦又不安全。为了解决这一问题,我们在轧臼壁与调整环间隙的上部用宽70毫米厚5毫米的钢板做成正圆拔销帽垫上,并在四个U型吊环上加装四根10×40×60的压缩弹簧,至今使用两年,尚未换修。
I mine a PYB900 standard cone crusher. In use, there are two problems that are hard to solve. Now we have succeeded in reform. One is the original crusher roll acetabular wall and adjustment ring, broken wall and the body of the infusion of zinc alloy between the body can only be used within a year or so have to be replaced for a few days, you have to spend thousands of dollars of money, And the operation is cumbersome and unsafe. In order to solve this problem, we make a positive-drawn pin cap pad on the upper part of the space between the nipple wall and the adjusting ring by using a steel plate with a width of 70 mm and a thickness of 5 mm and install four 10 × 40 × 60 compression spring, has been in use for two years, has not yet repaired.
