subject: Road Extended With Our Unremitting Efforts [print this page] The original machine adopts double screen frame, but because of the middle demi-screen frame directly bears the impact from the rotor and the chalk,which leading a larger worn of the middle and less worn on both sides.After the the excessive worn of the middle demi-screen leads the frame installation insecure and usually appearing the phenomenon of loose and peeling,which will cause a number of maintenance work.What"s more, the worn middle screen frame equals that the screen of about 14% of the material area were backed up, the broken qualified limestone in here can"t be put out, part of the chalk in crusher is repeatedly broken, leading to a low efficiency of broken, the time of yield is not high. The reforming measures: a. Remove the middle demi-vice screen frame and change the original double screen frame to a single one and then change the article screen of the original 2 to 1 root the root article screen. b. The material of the article screen remain unchanged then integrally cast a strengthen rab in the middle of the article screen to increase strength of the article screen and keep the turning circle distance of the hammer between the article screen invariant after the transformation. Due to removing the middle demi-vice article screen frame,the qulified limestone coal pulverizer through the screening area increased 14% or so of the article, and improve the crusher of crushing efficiency to a production increased to 65 ~ 75 t/h.The limestone of former 2.4 kWh/t power consumption has been reduced to 2.0 kWh/t.For every vice hammer gravel only 15000 t but after reform because of the increased production, 25000 t just needs to change the gravel 1 vice hammer. And the service life of the article screen frame and screen than before technical article extended for six months.Because of original article is easy to wear a sieve ,which leads the machine often to repair and a number of maintenance work and affect production.The problem has been solved after the reformation,and every month it will save 2 package stainless steel rod.As the professional manufacturer of complete sets of mining machinery, such as Stone production line,China mobile crusher,Wet magnetic separator, Henan Hongxing is always doing the best in products and service.
