Problems solved by technology
Since the mill is not equipped with a manhole door, it is impossible to directly pass through the manhole door. The traditional manual cleaning is estimated to take 9 days after the organization test during the maintenance period, which seriously restricts the maintenance progress; and the internal operation of the ball mill cylinder is a restricted space operation. There is a lot of powder and dust, and personnel cannot work inside for a long time; a large amount of manpower is required to work in shifts under ventilation, and the labor intensity of workers is high

Embodiment Construction
[0017] The manipulator is fixed at the feeding end of the mill. The beam, arm and gripper of the manipulator are located inside the mill barrel. The beam can be extended and contracted; length, shrinkage, etc.) fall to the position of the steel ball, the electromagnetic chuck is energized to absorb the steel ball, the arm action moves the electromagnetic chuck to a suitable height directly above the mobile belt conveyor, and the power is turned off, the steel ball sucked by the electromagnetic chuck falls on the belt conveyor and is discharged with the belt In the discharge funnel outside the mill barrel. The manipulator used in this example is a RUSSELL 7-axis mill relining machine (2500 kg rated load).
[0018] At the beginning, due to the charging rate of the steel balls in the mill, there were many steel balls inside the barrel, and the tail of the belt conveyor could not be fixed on the steel balls through the bracket. Material end) is fixed on the beam of the manipulato...

The invention relates to the field of large overflow ball mill volleyball. A fast volleyball method for a large overflow ball mill. Before maintenance, a discharge funnel, a material receiving funnel, and a movable belt are manufactured and tested; Unloading, unload the cylindrical screen at the discharge end; fixedly install the discharge hopper, the receiving hopper, and the discharge end of the mobile belt at the discharge end, and hang the electromagnetic sucker on the gripper of the manipulator; start the mobile belt and start The manipulator and the electromagnetic sucker absorb the steel ball through the electromagnetic sucker, and then move the electromagnetic sucker to the top of the mobile belt through the manipulator. Material funnel, repeat the above process, discharge the steel balls into the material receiving funnel, and the material receiving funnel discharges the steel balls into the car through the discharge port and pulls them away.
Description
technical field [0001] The invention relates to the field of large overflow ball mill volleyball. Background technique [0002] Taiyuan Iron and Steel (Group) Co., Ltd. Yuanjiacun iron ore beneficiation system has three series, which adopts two-stage continuous grinding - weak magnetic field - strong magnetic field - regrinding - reverse flotation process. The grinding system adopts 3 sets of Φ10.37*5.49 semi-autogenous mills, 3 sets of Φ7.32*12.5 ball mills, and 3 sets of Φ7.32*11.28 re-mills (large overflow ball mill refers to the steel balls in the cylinder with more than 300 Ton). [0003] In December 2017, during the system maintenance, it was found that there was a crack in one tooth of the large gear of the second series regrind machine, and the operation continued after simple treatment; On April 15, 2018, the large gear spare parts were overhauled and replaced after the third series of regrinding large gears, and on December 23, 2018, the second series of regrindi...
