SBM ball mill from China
Ball mill is the used widely stone grinding machine in the industrial powder grinding. According to the different application, ball mill can be divided into Ceramic Ball Mill, cement mill, coal mill and raw mill.
SBM ball mill
SBM ball mill from China is a Energy-saving ball mill for grinding after the crushing process, it is widely used in the fields of building materials, cement, mineral processing, chemical industry, glass ceramics, etc, it can grind ores or other materials with certain granularity into fine powder.
SBM ball mill from China features Large capacity, Easy operation, stable & reliable performance and Wide applicability. Generally speaking ceramics factories adopt intermittent ball mill. Within the inner tube of the ball mill loaded are some ceramic balls, materials to be ground and a proper amount of water which are properly matched according to process requirement.
During wet grinding process, when charge of ball-stone is up to 55% of net volume of ball mill, the best status can be realized. Wet ball mill smashes materials mainly through grinding instead of shocking, Therefore the amount of ball ball-stone should be properly reduced. Load of ball body relies on type of the ball mill and therefore the above rules are not suitable for dry grinding．
Rotary speed of ball mill plays an important role in ball grinding efficiency. If the ball mill rotates at the speed of critical or higher; there will not be any smashing effect. To increase efficiency of the mill one would have to tune the rotation velocity so that the average collision velocity becomes maximum.
Types of ball mill in China
The common classification of SBM ball mill in China is any type of mill in which mild steel or iron balls are used. In most cases the cylinder of such mill is made of alloy steel or some special type of lining.
SBM ball mill in China can grind various ores and other materials with dry type and wet type. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material.
These grinding medium ball sizes include: 3/4 inch, 7/8 inch, 1 inch, 1-1/4 inch and 1-1/2 inch..... about 400 grams of each size. With 285 balls always present, some balls of one size are removed and replaced with the next size of larger or smaller balls. Once a suitable grinding charge is prepared from one grade of balls, count and note the number of balls of each size.
Ball mill manufacturer in China
SBM is a famous ball mill manufacturer in China, and offer types of ball mill for sale used for wet or dry grinding application. SBM also design ball mill and grinding plant according to the capacity and grinding materials.
SBM Ball mill from China is cylindrical or conical shell rotating about a horizontal axis, partially filled with a grinding medium such as natural flint pebbles, ceramic pellets or metallic balls. It is vital equipment in industries viz. mineral dressing, ore processing, fertilizers, food and diary, pharmaceuticals and many others.
