Being The Professional Analyst Of Ball Mill

Ball mill main bearing bottom plate processing surface should be located in the same horizontal plane, the installation is available when liquid together with the device or level, level measurement, the longitudinal and transverse horizontal deviation not greater than 0.1mm / m, two floor relative height difference is less than 0.5mm, and the feed end higher than the discharge end.Ball mill bearing plate of the longitudinal center line of the coaxial error is not more than 1mm, the transverse center line of parallelism error no more than 0.5mm / m.Ball mill bearing on the spindle bearing base plate, so that the two center line, the bearing and the bearing seat contact surface along their sides should be uniform contact, local clearance shall not be greater than 0.1mm, does not contact the edge length shall not exceed 100mm, the cumulative length of no more than around 1 / 4 of length, otherwise, should be treated.The main bearing assembly accessories to find a positive effect, can be removed temporarily, to find it, according to the installation need timely installation of ball mill.Bearing installation on bearing pressure testing, its value should not be less than 25mpa, trial of continuous period of not less than 10min, such as the discovery of the complete elimination of leakage should be.Ball mill bearing seat is installed, should check the bearing seat of the cooling water hose and the end cover shaft neck and check whether a collision, thermal resistance and shaft neck contact is good.Thermal resistance should be installed in the shaft bearing plate and the bearing side, between each side should be 0.76 ~ 1.5mm space, finally the cleaning ball mill bearing seat of the foreign body, the ball mill bearing shell of useless holes are blocked.Grease filled bearing shell and the shaft neck contact rubber sealing grooves, at the same time test nozzle flow.In ball mill main bearing is installed, should be the bearing base, bearing the relative sliding fit surface is clean.(1) determine the distance between the two bearing axis by drawings, construct according to the case size after the assembles of the barrel and both ends (take the corresponding bulge and shrink size into consideration).The distance allowance in operation is ±1mm。 (2) the surface elevation allowance of the both main bearing bases is 0.5mm with the discharge end lower than the feed end.(3) when the bearing block of the main bearing is installed onto the baseboard, the joint surface should be contact evenly with each other with the local interval no greater than 0.1mm, the segment length of the non contact surface boarder not exceeding 100mm, and the accumulated length not exceeding 1/4 of periphery overall length.(4) clean the contact surface of the main bearing and the bearing block, lubricate them and make them well contact and move flexible.(5) clean up the cooling waterway of the main brasses and pressure test under the pressure of 1mpa.The connections should be strictly sealed without any leakage.(6) the outline of platinum resistance thermometer pt-100 of the main brasses is determined by the practical situation on spot.(7) the installation of the main bearing lubrication system.The installation requirements are as follows: clean up all the spare parts, reliably connect all the pipeline joint to make sure no leakage.With the development of society and technology, the new type of ball mill is introduced.Energy saving ball mill by feeding, discharging part, turning part, a transmission part ( reducer, small transmission gear, motors, electrical control) and other major parts.Energy saving ball mill hollow shaft with steel castings, the liner is detachable, rotary gear hobbing with casting, cylinder liner wear studded body, has good abrasion resistance.Energy saving ball mill runs smoothly, reliable work.Dryer machine:http://www.Hxjqchina.Com/product-list_35.Html spiral separator:http://www.Hxjqchina.Com/product-list_37.Html rotary dryers:http://www.Hxjqchina.Com/product-list_35.Html.
