The working process of the ball mill anchor bolt deviation is easily happened the situation that is different from the foundation drawing,this makes some deviation between the anchor bolt and the foundation,this deviation is the common phennomenon,this phennomenon in ball mill industrial called anchor bolt accident,if you happen this thing, do not worry,following the below 3 point can totally solve the problem.
1.Ball mill anchor bolt level deviation handling
If the standard height of the foundation more higher,then can sut some and use the tap to work out a thread.If the standard height is so low (deviation is less than 15 mm).The usual way is use the Oxyacetylene flame to make the bolt heated into red and elongation,both the two side of the diamter,it should be burn-on 2 rebar.If the standard height of the foundation bolt is lower,and the deviation is more than 15mm,then can not be heated methods,then we can cut off the foundation bolt and welding a new system screw the Chinese juniper,At the same time in the butt welding repair welding in four The root of the reinforcing steel bar. Level after the treatment, and should also complement placing of concrete.
2.Ball mill anchor bolt live drawing processing
When screw down the nut for the foundation bolt,Because overexert, use hammer wrenches, or because the installation is bad and cause shock Strike, vibration and other reasons,Anchor bolt from secondary water reserve the hole drawn out, this phenomenon is called 'live drawing' .The way to processing the accident,put anchor bolt lumbar coagulation chisel,And in the screw on welding two root U The steel bar, and then fill poured concrete, so that he may live drawn anchor screw inspection retighten prison.If because Lubricating oil etching secondary water layer joint surface cause of live dial the, the case shall then be partial foundation broken, new embedded anchor Bolt.Henan Hongxing Mining Machinery Co., Ltd is the professional manufacturer of complete sets of mining machinery, for example,cement rotating dryer, china dryer Welcome all of you to visit our official website.lime rotary kiln: http://www.crusher-machine.com/n231.html
3.Ball mill anchor bolt center distance deviation handling
When The local bolt center distance deviation more than allowable value is bigger, usable chisel to ball mill bolt nearby coagulation Soil, then use oxyacetylene flame heating bolt to light fuchsia (about 850 ?),But we must note temperature Too much, and requires a slow cooling, in case caused metal phase transition and reduce the bolt strength,After heating of the anchor Bolt available jack big hammercorrection, at the same time in 'bending place 'welding on a piece of steel plate, prevent tighten nut Will anchor bolt string. Anchor bolt center distance deviation handling well later, ought to fill placing of concrete.
