Rotating part of the installation a ball mill, ball mill cylinder and hollow shaft assembly to check the cylinder before the deal, the ovality tolerance not more than 5 mm. 2, Ball Mill with hollow shaft assembly, burrs on the joints. Burrs, etc. should be cleaned, and in joints coated with lead, contact joints should be tight and shall not join any alignment gasket. (1) When the main bearing assembly and tighten the Rotary dryer bolts pass only after the cylinder installed in the main bearings. 3, ball slewing bearings installed in the main part, shall comply with the following requirements: (a) After the Ball Mill on the spindle, check both ends of the elevation, the hollow journal on bus measurements. (Two) the relative elevation difference not greater than 1 mm, not less than the feed end of the discharge end. (C) two centrelines of the hollow shaft along the same line, Rotary dryer the hollow shaft with a dial indicator at the outermost end surface of indirect measurement, the runout tolerance of not more than 0.7 mm (not including the upper hollow shaft of the main bearing shift value). 4, large gear assembly: In order to facilitate transportation mill, a large gear in transit is separated into two half-ring, after being transported to the site, you need two parts will be assembled into a complete ring, the need to ensure a tight connection bolts curable. 5, the device based on the installation sequence: <1> should first put the lower portion of the gear cover; <2> Install the cylinder and the gear portion; <3> Install the upper portion of the gear cover. 6, the large gear and Rotary dryer cylinder assembly, the ring gear with hollow shaft flange face shall not be greater than 0.15 mm between the end of the gap, the large gear addendum circle runout after assembly shall not be greater than 0.86 mm, the reference face runout not greater than 1.2 mm, the size of the gear assembly of the backlash should be 0.53-1.4 mm, the two gear tooth contact area of not less than 45% higher and the tooth width of 60%. 7, liner installation (a) liner during installation, you should check in advance liner should not affect the Rotary dryer strength of defects, and then measuring liner on the back (ie by the cylinder side) arc meets drawing size, rear, and around the edges should be smooth, if applied at the wheel of injustice polished smooth, so as not to affect the quality of the installation. (Two) ball mill liner mounting direction, the direction must be installed in accordance with the drawings, shall be affixed to the contrary, the gap between the liner is not more than Rotary dryer 10 mm. Installing flat lining, should add a layer in the cylinder wall (1:2) cement mortar, and then use bolt tightening. (Three) ball compartment plate, grate plate installation, the gap between each block, not greater than the grate seam. Related Equipment: MBS type rod mill ball mill
