China's spiral separator: the ball mill, the jet mill, raymond mill, mixing mill, roll mill and column grinding machine, etc.The ball mill is still the leading grinding machine in china's cement industry, ceramic,dryer machine etc.The above equipment, although have many advantages, but have their weakness.For example,china vibrating feeder limited by technology and grinding machine processing characteristics of itself, most are unable to process the slag and fly ash, nonmetal materials of high hardness, especially the ball mill is noisy, high energy consumption and pollutive, cannot satisfy the required powder fineness production of high standard cement, high grade ceramic products and other new building materials.Artificial sand makerlarge multi-purpose spiral separator is different from the structure, process, grinding interface and principle and appearance of the traditional grinding machine, it is based on mechanical vibration principle, they can be work under the lower energy consumption.

Ball mill adopt of good quality tear elementscast metal in casting procedure is really typical with the procedure of cast metal products.For its top quality difficulty is be worthy of attention, so we should study concerning the consequences of numerous aspects of cast metal pieces of ball mill.Of course, not for ball mill, we also offer the add-ons of crushing plant, cement mill, effect crusher, jaw crusher etc.
Ball mill is used for grinding bentonite into powder in bentonite processing plant.Ball mill is an excellent tool to select mine or grind a variety of mine and other materials into fine powder.At the same time, on a wide range the ball mill is utilized in building material, chemical industry.
One essential tool that is heavily used in the mining industry is the powerful ball mill.People also call it a grinder.Thats because the main purpose of the ball mill is to grind and reduce the size of different materials.Even though the ball mills are most commonly used in the mining industry, these machines can be found in other industry sectors as well, like metallurgy, chemistry, ceramics and construction.This tool is described as highly efficient and versatile, as it can mix, blend, grind, and crush massive materials into fine powder.
The production of lead and zinc ore at 7.10 million tonnes in 2009-10 increased by about 6% as compared to that in the previous year.The metal content of lead and zinc in the ore produced in 2009-10 worked out to 129,752 tonnes and 745,969 tonnes, respectively as against 128,732 tonnes and 919,139 tonnes, respectively, in the previous year,ball mill is used widely in lead & zinc ores and concentrates(used ball mills for sale in india).
After we analyze its working principle, we will find that it is just suitable for cement production technology.This material in powder form can be changed from plasticity paste to hard stone-like body and can become a total cemented granular material through physical and chemical processes after being mixed with water.So it is a good mineral binder.It can be not only hardened in the air, but also better hardened in the water in which it will maintain and develop strength.So it is kind of cementitious material which will be of stronger hardness in water.Ball mill is used for cement grinding.In the concrete mining, you need to choose suitable grinding mill and impact crusher.
The rod mill is developed on the basis of the ball mill.It has the advantages of reliable processing technology, low investment, less auxiliary equipment and simple process flow.It can be combined with the ball mill to form a different grinding process.The rod mill mainly grinds the ore by the pressure and the grinding force of the grinding rod.When the rod hits the ore, it first hits the coarser grade ore, and then pulverizes the smaller-sized material, between the rod and the rod.When the rod is in contact with the wall, the coarser-grained ore particles are mixed with it, which acts as a bar sieve.The finer-grained material can pass through the gap between the rod and the rod, which is beneficial to the clamp.The coarser-grained material also allows the coarser-grained ore particles to be concentrated in the place where the grinding media strikes.Therefore, the rod mill has the function of selective grinding, and the product has a uniform particle size and less pulverization.
The procedure of the production line goes like this: the ore is first sent to 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.The ore powder discharged from the ball mill will be sent to the next procedure: classifying.Because of the different sedimentation rate due to the varied specific gravity, spiral classifier can clean and group the ore mixture.The cleaned and grouped mixture is sent to magnetic separator, due to the different susceptibility, magnetic substance can be separated from the mixture under magnetic and mechanical force.Then the mixture is sent to flotation machine, according to the features of different ores, we can add different additive into the mixture to separate the ore we want from the mixture.'after the separation from the mixture, the ore we want always contains a lot of water, we need a thickener to have it concentrated first and then dried by a drier; eventually we can get dry ore.
Our factory have a stone tin project in algeria.This tin mining process capacity is for 10 tons per hour, feeding size is for 450mm size.First use two step jaw crusher grinding stone tin in 0-20mm size.Then to ball mill grinding again, most time ball mill working with spiral classifier, spiral classifier can make big size to ball mill again, the small size to shaking table.Pls see the below picture.In the picture also have mixing tank and hydraulic box, it can uniform feeder material, and can separator different size again to shaking table, shaking table use different deck, then improve the tin recovery rate.
As we all know, the lining of the ball mill is a key part of the mill that can achieve high efficiency, energy saving and consumption reduction.After research and development, it has made good progress.
