A sag mill (semi auto-genous grinding) uses steel balls along with large rocks along with grinding.A rotating drum in a sag mill acts to throw the large rocks and the steel balls in a contracting motion and this results in breakage of the large rocks on impact and it leads to compressive grinding of fine particles.This is characterized by a large diameter and short length used sag mills are mainly used for grinding of gold, platinum, copper, lead, zinc and silver.There are hammer mills which are different from ball mills and rod mills which mainly help in shredding mining ore rather than grind it.
Ball mills,rod mills,flour mill,tube mills,ceramic ball mills,rod mills are both excellent mining machines for grinding ores into fine powders and particles.
No matter what the grinding medium in the ball mill cylinder is, the finished material size varies with the medium size, hardness, quantity, etc.
1.The ore is firstly sent to the jaw crusher for primary crushing.Then the ore with a proper size for secondary crushing will be sent into the ball mill for fine crushing and grinding.
What makes the ball millso popular machine around the world is its incredibly simple but highly efficient working principle.It works on the impact principle.First, the materials that need to be reduced in size are loaded into the rotating barrel of the ball mill which is composed of grinding balls, also known as grinding media.The grinding balls are usually ceramic or are made from stainless steel.When the ball mill is turned on, the grinding balls in the rotating barrel crush and reduce the size of the materials inside.
12 ft x 14 ft marcy ball mill, complete with 1,750 hp synchronous motor, 200 rpm, 2,300 volts.New trunnion bearing base plates, new pinion, 3 shells to choose from, three discharge heads and 3 intake heads to choose from, two bull gears.
Minted ball mill steel balls is steel, iron and other electric furnace heated up charge use to make the charge sufficiently melted, add the amount of precious metal alloys to charge the melting furnace in the process of chemical ingredients quenched until the hot metal temperature above 1550 and meet the technical requirements after passing the molten iron is poured into molds or ball production line ball mold.Which is manufactured by casting melting approach is called casting ball out of the ball.

3.The feeding size can be very large and usually can be up to the length as 5% of the roller diameter.The large ball mill's feeding size can be up to 150 ~ 200 mm.The equipment has superior technical performance and is of high capacity.It has high rate of operation and lower metal-worn than the ball mill.
The ball mill is a key piece of equipment for grinding crushed materials, and it 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.The ball mill can grind various ores and other materials either wet or dry.There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material.There are many wet ball mill suitable for use in a ball mill, each material having its own specific properties and advantages.Key properties of grinding media are size, density, hardness, and composition.
The noises produced by the energy-saving ball are generated by the impacting and grinding between steel ball, materials and scare board.The noise belongs to the mechanical noise and radiate outside along with the surface of the tank.The noise can be different when the size and quantity of the crushing material is different, even the same type energy-saving ball mill in the same sand making line.
For smooth and efficient grinding process, the ball mill should be operated at low operating speed, especially if the material needs to be crushed into fine powder.Therefore, most manufacturers design ball mills with low operating speed, because a very slow operation is the main advantage of this grinding machine.When using a ball mill, it is very important to grind only smaller materials in the barrel, since bigger materials may cause some damages to the grinding media.
