The cement mill is key equipment for the grinding process of the cement clinker after the crushing process of it. It is mainly used in the cement silicate product industry. After long term design and manufacture of the cement mill, our company now has series of cement mill with various specifications to meet with different requirement from our customers.
When the grinding mill is at work, the main bearing and each dial are driven by electromotor through reducer, and all the grinding rollers are rolling in the ring channels driving by dial through plunger. The materials are driven to the edge of the turn plate by the centrifugal force and fall down into the grinding chambers. The high-pressure air blower constantly inhales air, airflow with crushed materials are brought to classifier whose high-speed impeller will screen the airflow: The unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; A small proportion of the fine powders, with airflow, moves to the dust cleaner. The materials from the above two lots are sent by the conveyor to get finished powders packed. In addition, filtered clean air will be emitted from muffler in the end.

Such crushing equipment has its drawbacks which are usually specified as high price, large dimensions and high power consumption. However, the Strommashina has improved the ball mill design over the past decades. It eventually enabled optimising power consumption and reducing the mill manufacture cost. In addition, the plant engineering department is available for calculating the mill dimensions for customised production needs, and for performing all necessary equipment installation and start-up works.
The classifier can form a closed circuit with the ball mill for distributing the ores, grading the ores and fine mud in the gravity mills, grading slurry in the metal ore dressing procedure or for desliming and dehydrating in ore dressing process.
“The new IAF technology extends the efficiency and environmental sustainability benefits into new markets, by extending the capacity of flotation systems to generate bubbles at temperatures above 80oC, the usual limit for DAF systems. This opens up the potential for new levels of efficiency in high-temperature applications, which also benefit from reduced energy consumption.
A ball mill works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
Copper pyrites contains only (2-3)% of copper. The rest of the ore contains iron or sulphide, silica, silicious materials, sulphur, arsenic etc. as impurities. Froth flotation by Xanthate and pine oil. The froth is collected and dried when concentrated ore is obtained which contains 25-30% of Cu.

Preparation and use. Pure iron is produced in relatively small quantities by electrolysis of aqueous solutions of its salts or by the reduction of iron oxides by hydrogen. A method of producing iron directly from its ores by electrolysis of melts is being developed. The production of iron of sufficient purity by direct reduction of ore concentrates with hydrogen, natural gas, or coal at relatively low temperatures is increasing.
Gary Pearse, Tantalex's Qualifed Person (QP), remarked: "A discrete, coincident K-radiometric and magnetic anomaly of this shape and size on strike with Manono- Kitotolo pegmatites makes for an exploration target of considerable interest. The continuation to the southwest of this corridor on the magnetic maps warrants definitive exploration follow-up. Moreover, the presence of a "parent granite" on the property suggests good potential for discoveries of lithium rare metal pegmatite deposits on the Buckell property".
Explosion-proof filter is adopted. Gas is sent into filter directly from mill. This system is with less equipments and simple Configuration.

High Efficiency Milling (HEM) is a strategy that is rapidly gaining popularity in the metalworking industry. Most CAM packages now offer modules to generate HEM toolpaths, each with their own proprietary name. In these packages, HEM can also be known as Dynamic Milling or High Efficiency Machining, among others. HEM can result in profound shop efficiency, extended tool life, greater performance, and cost savings. High performance end mills designed to achieve higher speeds and feeds will help machinists to reap the full benefits of this popular machining method.
In addition to the well known and commonly used vacuum disc filters, a reliable and low operating cost filtration solution with a large filtration area for high capacity and stable product moisture content has been developed and will be steadily improved according to process demands. This filter is called the Outotec Larox CC, Ceramec capillary action filter, which guarantees stable capacity and good moisture results with low capital investment and operation costs and easy maintenance and monitoring.

One of the great things about this product is that it is actually fun to use. Simply load up the front chute with salt and turn the crank handle. Salt will immediately be deposited so that it is ready to use. There are also adjustable settings to achieve the perfect coarseness.
The Ball/Rod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level. They are the most effective laboratory mills for batch-wise, rapid grinding of medium-hard to very hard samples down to finest particle sizes.
Working principle:The Electrical sorting method used the differences of conductive of different mineral, Under the influence of electric field, mineral particles are subject to electrical and mechanical forces(centrifugal force, gravity, drag) role, then they produce different tracks that make them to be separated, so we can achieve the purpose of sorting.When the temperature heated to 40°C-60°C after entered into the bin. the mineral particles enter into the power corona areas with the rotation roller shafts along the rotating feed roller(Grounding Electrode)surface, Corona current makes all the mineral particles(conductors and non-conductors) obtain negative charge, Because of low contact resistance. with the rotating feed roller, the conductor's charges transfer by the roller away quickly, Under the action of mechanical forces, conductors escape away from the roller, and enter into the mineral hopper(conductors), At the same time, because of higher contact resistance with the rotating feed roller, the non-conductors'charges couldn't transfer by the roller away as quickly as conductors', so they are forced in the roller surface owing to the role of electrostatic force, with the rotating feed roller, the non-conductors enter into the back of the roller, and are unloaded under brush, Then they are collected in the excellent hopper(non-conductors), At last the Semiconductor mineral particles or failed to fully discharge the conductor mineral particles enter into the middle hopper(semiconductor mineral particles).
