A ball mill is an ore grinding mill that can crush and grind various types of ores to liberate the closely associated minerals from each other. Ball mills are widely used in cement making and ore beneficiation plant.
When the ball mills begin to rotate, grinding balls will slide up the side and be held in place by centrifugal force. As the ball rotates to the upside of the rotating drum, the weight of the balls overcomes the centrifugal force which is causing them to cling to the inside of the liner. When the balls move to the top side of the drum, they'll tumble back down roughly.
The most common grinding media used by ball mills are four types: steel balls, pebbles, ceramic balls, and grinding cylpebs. Although ball mills are similar with each other, they are different in grinding media, working capacity, application fields.
Dry means little water and moisture in the grinding process. Tpically the ball mill maybe charged with 30% to 45% of balls. With the rotating drum, the ore is rubbing against itself and the moving balls, and the process is going to continue from the inlet to the discharge port.
Wet means that we add water and form a slurry, and that slurry is going to occupy 50% of the ball mill volume. In a wet ball mil, approximately 15% water may form slurry which is a mixture between water and the crushed ore, sometimes also referred to as pulp.
As the balls drop down onto this slurry, and some of the slurry is also taken up with the balls, the balls are going to impact and grind the slurry(ore and water) so that you can get the ore size reduction.
The ball mill plays an irreplaceable role in the beneficiation production. In the process of extracting metal ore, because of the ore minerals with fine dissemination, it is necessary to grind the ores to a fine level to dissociate the useful minerals and gangue.
The roller crusher, a large crushing equipment, can compensate for the insufficient capacity of the ball mill when working with ball mill together, and double the production capacity of the ball mill;
High grinding efficiency and good quality of the liner: The lining and grinding body are made of alumina ceramic, quartz, SILEX or special materials, and it is designed with no iron pollution when crushing hard materials;
Closed system to reduce dust: Ultra-fine ball mill and classifier form a closed system with advantages of negative pressure delivery, low dust, reducing damage to the human body; Besides, the ball mill has higher product quality and cheaper operating prices.
India is a populous country in the world and one of the "BRICS" countries. It has good cooperation and win-win relationship with China. For machinery processing enterprises of China, the business opportunities contained in India are limitless, and mining equipment from China is entering deeply in India market.
With the gradual recovery of the mining market, the market position of mineral processing equipment is more stable with the increasing position. The cement ball mill produced by Fote is more prosperous in the Indian market.
The cement ball mill is mainly used in the grinding of finished products and raw materials of cement plants for open-flow grinding, and also for circulating circulation grinding with the powder separator.
It has the characteristics of strong adaptability to materials, continuous production, large crushing ratio, and easy to adjust the fineness of the milled product. The cement ball mill can be produced either dry or wet, or both at the same time as grinding and drying.
In February 2018, an Indian customer contacted us and hoped to purchase a large ball mill equipment for his ore dressing line. Because our company has a large number of ball mills exported to India, the customer finally chose us to provide with a little investigation.
The mining of high-quality iron fine powder with grade of 67.50% is gradually advancing to the deep mines, and the annual output of the main mining area has dropped from the original 10 million t/a to 6 million t/a.
The ore in the mining area has fine grain size and complex mineral composition. It is a difficult to grind ores, which has caused large fluctuations in the quality of concentrate in recent years, and a decline in concentrate output.
After repeated research with experts, the company chose a solution with low investment and fast efficiency based on the actual situation, that is, the design of adding a one-stage grinding and dressing process. They transformed the original two-stage grinding and dressing process into a three-stage process, so that the ore is fully finely ground to achieve monomer dissociation. That design ensured the quality of the concentrate while maximizing the metal recovery rate.
2 Compared with the general separation before the transformation, the metal recovery rate has increased by 6.73%, and the annual processing of 2 million tons of transition type ore increases the production of iron concentrate by 35,200 tons.
3 It also helped to release original ball mill feeding capacity. Compared with the original 3600 mm6000 mm and 2700mm3600 mm ball mill before the transformation, the new process increased the average processing capacity increased by 7.58t/h and 0.82t/h respectively.
5 Based on the current price of iron concentrate, the successful operation of this project can increase the sales revenue by 5.94 million $/a, and it can create an additional profit of 1.92 million $/a.
The grinding balls are mainly made of high manganese steel: it makes ball mill balls good toughness, good manufacturability with low price. Its main feature is that under the action of greater impact or contact stress, the surface layer will become harden quickly. Its work-hardening index is 5-7 times higher than other materials, and the wear resistance is greatly improved.
Big gear is an important part of ball mill, so the choice of big gear is a crucial process when produce a ball mill. According to the working conditions of the big gears, they are usually manufactured as follows:
The structure of the ball mill big gear has various shapes due to different requirements, but from the technical point of view, the gear can be regarded as composed of two parts: a ring gear and a wheel body.
Fote ball mill manufacturer has 40 years of producing experience. Due to the continuous improvement of machine itself and production capacity, it has won the recognition of customers at home and abroad.
Even during the Covid-19, according to different national policies, as long as countries where conditions permit, we will always deliver the products to customers in the fastest way and put them into production on schedule.
2 The production capacity should be higher than design: The designs should take the change of hardness and fineness of the ore into account. Generally, while the deep ore of the ore deposit becomes hard or thin, the selected grinding machine should be able to adapt and ensure that the initial operation runs well.
3 Grinding test is a must: When there is no actual data in the designs, the grinding test must be required. Especially for large-scale mines, the grinding machine selection calculation and proportional enlargement should be carried out from the basic data obtained.
4 Due consideration of large-scale equipment: The large-scale equipment is the trend since the 21st century because of its advantages of light in total equipment, small in area, few in operators and auxiliary systems, and correspondingly low in investment and production costs.
5 Select equipment with high operating rate: There are also good and bad points in the same type of equipment. Rod mills and self-grinding machines sometimes have lower operating rates but are still suitable under certain conditions.
