Rod grinding mill is widely applied in metal and nonmetal mine, chemical, metallurgy, water conservancy, glass and construction materials industries, mainly suitable for grinding various ores and rocks and artificial sand-making. Our high-efficiency wet rod mill adopts rolling bearing support instead of sliding bearing support with bearing bush. Therefore, it has advantages of even discharging size and high capacity. It is composed of feeding part, discharging part, turing part and driving part. Because of the infrastructure of natural sand resources growing in the field of many appear gradually reduce, even with no natural sand. Sand concrete sand is extremely short, and the quality from the demand is higher and greater. Especially high strength grade and the sum of the high performance concrete is really strict, in order to meet what’s needed of the fewer the amount of natural sand.Rod grinder is characterized in the process of grinding, the grinding medium and the ore is line contact, thus has the certain selective grinding function. Product size uniform, have crushed ore particles less. For coarse grinding, grinding rod mill processing capacity greater than with the specifications of the ball mill. Rod grinding machine by simple adjustment can change the discharging granularity, built-in fineness control device, discharge and screening device, two checks, ensure that neither had a mill and make no unqualified products into the finished product. In addition, this type ores grinding rod mill may have many other problems, such as Main bearing fever, abnormal sound, motor overload power. Bad lubricationMain bearing into the sediment; Bearing damage; Main bearing installation is not straightFeed amount more or less; Add lubricant; Clean bearing, replace oil; Replace the bearing; Adjust bearing; Adjust the amount of oreMotor overload or cannot start before the start of no plate mill. Rod mill adopts a medium of a barrel length as short as 10 ~ 15% of steel round bar....
