Henan Zhengzhou Mining Machinery Co., Ltd (ZK) is an integrated modern enterprise which is a collection of scientific research, design, manufacture, marketing, installation, debugging and training service. The technical and research team makes independent research and development to produce under the absorption and the introduction of foreign advanced technology. Double row self-aligning roller bearings are used in ZK new type energy-saving ball mill transmission system instead of sliding bearing, thus the original sliding friction is turned into the rolling friction, which reduces the friction force and the resistance, saves the power consumption and cost, prolongs the service life.

ZK energy-saving ball mill is mainly composed of rotary part, main bearing, feeding device, discharging device, and transmission device and so on.

Both ends of the energy saving ball mill adopts rolling bearing to replace the sliding bearing, the energy saving ability is remarkable, and the matched motor power can be reduced by 18 -- 25%, and the lubricating oil is saved by 70%, and the cooling water is saved by 90%, and the comprehensive energy saving is more than 20%. The main component of this ball mill is a cylinder with a smaller diameter and larger length which is slowly rotated through a transmission device. The material to be milled is fed into the mill through the mill feed end, the grinding media and material are brought to a certain height, they are thrown and spilled under the action of friction and centrifugal force generated by the rotating movement of the cylinder, then the material is grinded by the grinding medium. The continuous feeding material urges the material in the cylinder to move from the feed end to the discharge end and the material matching the size of the finished product is discharged from the cylinder.

Installation and attention matters:

1 Check the quality of cylinder, gear, hollow shaft, reducer and other major parts, if there is damage and deformation, it should be solved in advance.

2 Clean up parts of the installation, the parts with orientation, such as ladder liner, spiral tube and lifting plate, must be installed according to the technical requirements.

3 Check the relative elevation after two main bearing chassis being installed, its error should be less than 1.5 mm and the feed end is not allowed to be lower than the discharge end. After two after the main bearing being installed, their longitudinal center line must be coincident, its misalignment franchise is 0.8 mm; their horizontal central line must be parallel, and its nonparallelism franchise is 0.9 mm.

4 The contact area of the big gear and small gear meshing is not less than 60% along the tooth width is not less than 80%.

5 When installing the liner, the gap between the lining board and the lining board is 5--10 mm. Carefully seal the packing, gasket and a lock washer to prevent leakage of powder and lining board loose.

6 After the gear cover is assembled, there must be no oil leakage and gear collision.

After the machine is installed, it must be empty and full load tested, after passing the official use, the factory should develop the operation, maintenance, overhaul system, to ensure the normal operation of the mill.

Maintenance of mill

1 Check whether there is noise and vibration when the speed reducer is running.

2 Check that if the anchor bolts, lining plate bolts, grinding door bolts are loose, and they should be tightened in time.

3 Check the wear and tear of the sealing washer and replace in time.

4 Note and record the change of motor current, if the current abnormal changes, stop the mill and inspect it.

ZK new type energy-saving ball mill is widely used in dry grinding and wet grinding and it is your best choice. Welcome to visit our factory, we provide you with professional services.
