subject: Easy Operation Of Ball Mill For Your Convenience [print this page] The ball mill is mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball Mill has dry and wet ways. When wet Ball Mill works, certain water and other liquid will be added into materials to increase flowability of materials, so the capacity is increased. When dry Ball Mill works, capacity is affected because material flowability is reduced, so absorbing wind device is needed on the outlet of Ball Mill, and then negative pressure is formed in the Ball Mill to increase flowability of material, so the capacity is increased.
Grate ball mill primarily consists of six parts, viz, the barrel, feeding part, discharging part, bearing part and lubrication system. The lining plate is installed inside the barrel, whose materials are from manganese steel, chrome steel, cast iron, and rubber. Theres a hole in the barrel for the use of maintenance and changing of the liner.
Overflow ball mill is basically similar to the grate ball mill in structure, also composed of six parts. The difference is that theres no grid plate device in the discharging part and the overflow ball mill is simpler than the grate ball mill in structure. Compared with the grate ball mill, the overflow ball mill discharges slower. It is suitable for fine grinding and requires prompt adjustment due to its sensitivity towards the change of the outside elements. Besides, its structure is simple and the maintenance is convenient.
The installation of the ball mill.
a) Cleaning the foreign body inside the preserved holes in the installation equipment, especially no dust, oil stain or water is allowed inside the hole wall;
b) After unpacking the packing case, the host machine should be moved to the installation place by proper lifting facilities (crane/forklift);
c) Position the device carefully; anchor bolts are installed inside the hole, then thrusting the adjustable feet with anchor studs after welding it to the rack chassis which is accompanied with the machine. Finally, a secondary grouting is able to be processed;
d) Tighten the bolts, loading and testing the machine are permitted only after 24 hours;
e) Connecting to power;
f) Installing and checking, correcting the faults;
g) Electrical cabinet is positioned in the auxiliary engine room without being installed.
Commissioning:
After installation and is qualified through inspection, the ball mill is allowed to empty commissioning, which the operator should take charge to process. And it is indispensible to observe the safe operation practice of the ball mill.
1.The continuous empty operation time should be no less than 12 to 24 hours, and the problems found during the operation ought to be resolved promptly.
2.If the empty commissioning is normal then it is available to loading commissioning, which should be proceeded in stages. It ought to feed considering the discharging situation to avoid unnecessary abrasion and damage between the steel ball and cylinder liner.
3.Adding appropriate amount of materials and one third of steel balls (cf. general drawing of the ball mill), and the commissioning time is 12 to 24 hours.
Ball Mill Features:
1.Large application range, simple structure and convenient maintenance;
2.Large capacity and continuous work are very obvious;
3.Barrel lining and grinding media can apply various abrasive materials;
4.Installation and adjustment are very convenient and easy to be operated. Related: dry grid ball mill wet ball mill
Choosing the type of Ball mills:
1. Know the hardness of your own ore.
2. Choose the energy-saving ball mill to the great extent.
3. Know the ore fineness required.
4. Choose the right diameter and length of the ball mill according to the output requirement.
5. Buy it from the professional Ball mills manufacturer relative to your ore which would be best.
6. The manufacturer should hold the market share in the place where your enterprise located.
7. Choose the new-type transformation ball mill with the rotate speed different from the module.
8. Choose the aperture of the close board and the sub-freignt space according to the ore fineness of your demand.
9. Choose the lining board material and set the thickness of the steel plate on the mill body by the price of the Ball mills.
10. Select the modules of the big gear and pinion, and the manufacturers of the electric motor and the speed reducer.
As a professional ball mill manufacturer in Henan HXJQ CO.LTD, has 20 years of production experience, advanced ball mill technology, strong technical, reasonable ball mill price, welcome consumers to visit consultation. The Ball Mill is a key equipment for grinding the crushed materials, and the ball mill is widely used in powder-making production line including cement, silicate, new-type building material, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. And the ball mill can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grate type and overall type due to different ways of discharging material. Our ball mills can satisfy different requirement, and have good features such as low consumption, high capacity per hour, and no pollution to the environment around, easy to be repaired.
