The structure of the overflow ball mill is basically the same as that of the lattice ball mill, except that there is no discharge lattice at the discharging end of the cylinder. Furthermore, the surface of the hollow journal bushing is equipped with an inverse spiral blade, which can return the spilt balls and coarse ores from the slurry to the mill. The grinding product of the overflow ball mill is free overflow through the discharge hollow journal. For this reason, the level of slurry in the cylinder must be higher than the lowest busbar level of the discharge shaft neck.

We have in particular long experience in mill testing, study, design, made and filed operation, and made advancement and innovation on foreign technologies. Now we have established our own grinding laboratory, formed various type mills to series, totally produced nearly 1000 sets, and exported to Australia, Russia, Pakistan, Zambia, Indonesia, Vietnam, etc. We have produced the overflow ball mill with the largest size Φ5.5�8m, Φ8.5�4m semi-autogenous mill, Φ5m vertical cement raw mill, etc. Our company possesses the national first-rate study and design group on mills, perfect experiment and testing measures, and superior manufacturing equipment and technology on large-scale mills. We have formed complete supplying system for mill experiment, study, design, manufacture, testing and service. Application Scope: For grinding of various ores and rocks, widely used in non-metal mines, ferrous and non-ferrous metal mines, construction material, hydraulic engineering etc. Working principle: There are many grinding medium balls inside the continuous rotating drum (there are many rods inside the rod mill). The continuous feeding material is broken by the shooting balls which are coming from a certain height of the wall of the drum; The falling medium and material would produce irregular slip and roll during the rotation of the drum, and the material is pulverized fine by the grinding effect among medium, drum-lining and materials. The dynamic material level different is produced by continuous forced material charge and discharge, consequently more and more fine material is slow out from the drum, and finish the grinding process inside the drum.

Ball mill
The ball mill is a key equipment to grind 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 overfall type due to different ways of discharging material. Working Principle: The ball mill is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and ripple liner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished. Standard packing
Ball mill is an efficient tool for grinding many materials into fine powder. The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine.2 It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine. To use the Ball Mill, the material to be ground is loaded into the Neoprene barrel that contains grinding media. As the barrel rotates, the material is crushed between the individual pieces of grinding media that mix and crush the product into fine powder over a period of several hours Quite simply, the longer the Ball Mill runs, the finer the powder will be. Ultimate particle size depends entirely on how hard the material you're grinding is, and the time how long the Ball Mill runs. Our Ball Mills have been used to grind glass, powder food products, create custom varnishes, make ceramic glaze, powder various chemicals, and make Black Powder Specification of Ball Mill: Name & spec.: MQG900*1800 Speed of bucket (r/min) : 38 capacit¨t/h: 0.65-2 Feed size£¨mm: 20 Final product£¨mm: 0.075-0.89 Mainframe motor£¨kw: 18.9 weight:3.6 Name & spec.: MQG1200¡Á3000 Speed of bucket (r/min) : 32 capacit¨t/h: 1.6-5 Feed size£¨mm: 25 Final product£¨mm: 0.074-0.4 Mainframe motor£¨kw: 45 weight:12.8 Name & spec.: MQG1830¡Á7000 Speed of bucket (r/min) :24 capacit¨t/h: 7.5-17 Feed size£¨mm: 25 Final product£¨mm: 0.074-0.4 Mainframe motor£¨kw:245 weight:36 please contact with cherry lee!
Ball mill for lead oxide is a basic device in the modern world of metallurgy and is extensively used in a variety of applications. Among others, it's applications in the processing of non-ferrous metals is one of the most important. In the field of lead processing, dry type ball mills are used for conversion of lead pellets into fine lead oxide powder (lead oxide free lead), also commonly called grey oxide due to its appearance. The ball mill with its preparatory and collecting equipments is therefore also called a grey oxide plant. Description of process: Lead is melt in a melting pot and cast into pellets (hemispherical or cylindrical shape) at a ball making machine and fed into the ball mill. The ball mill is rotated on its own axis at low speeds. The rotation of the mill imparts tumbling & cascading action to the balls fed (in this case the lead pellets). The rotation is adjusted so that the raw material inside does not reach critical speed. Below the critical speed (at around 65 - 75%), the balls which are carried along the walls of the mill fall back to the center. This continuous action leads to friction and generation of heat which induces the reaction of lead (pb) with oxygen (o2) present in air and generation of lead oxide (2pbo). This reaction is an exothermic reaction which leads to generation of heat and this sets of a chain reaction of heat generation and accelerated oxidation process. Draft of air through the mill carries small sized or light particles outside the mill to the collection system. Temperature within the mill is controlled with the help of water spray outside the barrel of the mill. Several crucial characteristics of this produce such as free lead percentage, retention percentage, apparent density are set as per requirements of the client.
