ball mill important component Disassembly and repair methods

In the mill operation process, if required fault occurs on the ball machine parts removed for repairs, remove the right way will save time and effort. In this paper, Xiao Bian Weapon for you, so you save time and effort. Ball mill grinding roller device, disc apparatus and gear called a ball of core components, if these places is a problem, it may be necessary to strike a ball mill myself! Do not worry, Xiao Bian Weapon neat and quick for you to get your equipment heavy show power!

Internal structure of Shanghai World state ball mill

First, the removal and repair methods grinding roller device: Roller sleeve and the roller bearing on the ball mill wear parts, generally when the roller device is a problem is that these two parts of the problem, they just need to split out maintenance on it.

Replacement Procedure roller bearings or sleeve:

a, carefully read the relevant sub-components roller device, actuator arm, hydraulic schematic drawings, etc., to determine the maintenance program;

b, the ball mill roller door on the housing removed;

c, cylinder pressure relieved work, so roller assembly by gravity falls on the disc;

d, remove the ball mill for sale dynamic coupling between the rocker arm and pin;

e, will be linked with a pin and rocker arm, the hydraulic system in the maintenance status, start the pump motor, step by maintenance lift cylinder will roll grinding roll pulls the machine, until after grinding roller device into an upright position, the high-pressure cylinder immediately corresponding high-pressure pipeline shut-off valve manually shut down after Globe, remove the stud fixing roller sleeve and pressure ring, you can remove the roller sleeve (if replacement bearings, roller assembly as a whole must be from a shake arm removed, transported to the machine repair shop maintenance), then put on a new set of rollers or roller sleeve upside down, the assembly should first clean the joint surface of each piece, after assembly is completed application feeler binding of the joint surface. After the roller sleeve for good, you can press the overhaul cylinder will roll grinding mill fell into step inside the roller assembly into the grinding chamber.

Second, the method of disc repair ball mill device:

a, steps in the overhaul of the roller sleeve or bearing roller assembly pulls mill outside;

b, open the access door to the next casing inspection, replacement scraper plate scraper device;

c, first bolt disc liner pressure ring and pressure ring removed, remove the pressure ring, with a crowbar to pry liner hanging out the grinding chamber, and then replace the new liner. Should try to ensure the smooth installation of the liner between the liner and the liner, each corresponding to the pressure ring should be a piece of liner pressure prison, not loose, liner installation and compression ring can not cross the gap between the liner application securely plugged oil immersion asbestos packing, prohibit the use of a metal filling.

Third, the actuator overhaul: Reducer is a core part of the drive unit, repair methods listed here gearhead.

a, attached to machines and systems to ensure that all of the mill shut down;

b, remove the disc unit fixing bolts and dowel pins;

c, open the top of the disc body straight down the feed tube, the upper shell casing (Manhole top, bottom ash hopper where the symmetrical position) welding lifting fixture (not affect the roller device pulls mill outside);

d, remove the motor, coupling bolts and pipes out of the lubricant, and then remove the motor;

e, with 10t chain hoists to lift the disc device, and to make it out of gear;

f, remove the gear bolts, and then from the lower mill gear removed, transported to a machine shop maintenance;
