Product Introduction
Brief introduction of ball mill
Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill. The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed.
Main features of the forging ball mill
According to the way of materials and discharging, ball mill can be divided into dry type ball mill and wet type lattice ball mill.
Ball mill is mainly made up of feeding part, discharging part, rotary part and driving part, including reducer, small drive gear, electrical machine and electronic control. The hollow shaft adopts steel casting, and its inner lining is detachable and changeable while the rotary rack wheel uses casting gear hobbing and there is a wear-resisting lining board inside the cylinder with good abrasion performance. This machine is featured with stable operation and reliable performance.
1) to grind various of mine materials and other materials;
2) two ways of grinding: Dry-type grinding and wet-type grinding;
3) good wear resistance with wear-resistance liner plates;
4) reducing energy cost by 30%, with double rows of aligning spherical roller bearing;
5) high-grade steel welding, reliable work condition;
6) fine grinding, capacity rising by 15-20% compared with traditional ball mill;
7) finished particle size depends on hardness of materials and the time of ball mill runs;
Product Application
Main application of ball mill
Grate Ball mill is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous non-ferrous metals.It is used for fine grinding of feldspar, quartz, clay, ore and other raw materials
structure
INTERNAL STRUCTURE OF CERAMIC BALL MILL
Although ceramic liner ball mills and ordinary ball mills have similar shapes and working principles, ceramic liner ball mills have unique advantages in many industries, which are also not available in ordinary ball mills. For example, in the mineral processing industry, many of the grinding processes of raw materials cannot have the participation of iron metal, otherwise the quality and value of the finished product will be greatly affected. At this time, it is necessary to choose a mill with ceramic liner. In addition, the ceramic liner is very wear-resistant, the service life is also greatly extended, for the same material, the service life of the ceramic liner ball mill liner can be extended at least several times.

Our Advantages
Advantages of ball mill
1. As the ball mill transmission adopts rolling bearing instead of sliding bearings, friction is greatly reduced with easy start-up and significant saving energy;
2. Its discharging end adopts cone design, which not only increased the volume, but also forcing grading of ball in cone side. The closer exit, the smaller ball diameter. It increased function of repeated grinding, and further improve fineness of the material;
3. It adopts grooved ring-type lining plate, increased contact surface of ball ore, strengthen grinding effect, has hoisting capacity to ore and reduced power.
4. It adopts whole rack, convenient for civil construction and equipment installation.
Working principle
Working principle of ball mill
The hole in grid lining plate is arranged obliquely, the width of the hole is gradually expanded toward the end of ore discharging to prevent pulp backflow and coarse grain blocking. Pulp flows into fan-shaped through pore of grid lining plate in the lower part of ore discharging, and then goes to upper part with barrel and discharges it along with pore passage. Hollow journal is set with wear-resistant inner sleeve, and one end is made into tubaeform blade so as to guide pulp to flow out mill along blade. This pulp mill is discharged through ore discharging devices of grid plate.
The motor on the ceramic ball mill drives the cylinder rotation through the deceleration device, and then the crushed ore and grinding ball in the cylinder are brought to a certain height by friction and centrifugal force when the cylinder rotates, and after the liner is brought to a certain height due to gravity, it will be thrown and falling, and the ore will be gradually crushed under the action of impact and grinding. The crushed stone is discharged through the discharge part.
After the discharged material is classified into a qualified product in the spiral classifier, the coarse sand is returned to the ball mill through the combined feeder to continue grinding. The feeder feeds continuously and evenly, and the ore enters the ceramic ball mill continuously and evenly through the combined feeder, and the ground material is continuously discharged from the ceramic ball mill. Ceramic ball mill is a grinding equipment that can work continuously 24 hours a day.
