The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media , the product to be ground is added and the cylinder is put into rotation via an external drive causing the media to roll, slide and cascade. Lifting baffles are supplied to prevent the outer layer of media to simply roll around the cylinder.

Mill cylinders are typically supplied with a cooling jacket on their cylindrical portion for temperature control, especially when processing temperature sensitive materials. For extreme temperatures, the ends of the cylinder can also be furnished with cooling apparatus.
The LED industry is in short supply and continues to prosper for at least 2-3 years.
The domestic LED industry 2016 annual report and the 2017 first quarter report have been released, and the overall results have been reported. Among the 2017 first quarterly reports, 40 of the 43 LED listed companies saw a year-on-year increase in revenue, and 35 LED companies reported a net profit increase of 1 year in the first quarter, with 27 listed companies whose net profit increased by more than 30%. In the domestic LED industry 2016 annual report and 2017 first quarter report has been released, the overall performance has been reported. Among the 2017 first quarterly reports, 40 of the 43 LED listed companies saw a year-on-year increase in revenue, and 35 LED companies reported a net profit increase of 1 year in the first quarter, with 27 listed companies whose net profit increased by more than 30%. The proportion is over 60%. The LED industry's core financial data improved significantly, verifying that the LED industry trend is solid and reliable. From the LED industry's 2016 and 2017 first quarterly reports, the core financial indicators of listed companies all show a significant improvement trend. Core indicators include ROE, revenue scale and increase. Speed, return to home net profit and growth rate, gross profit margin, net profit and operating cash flow. LED industry trends have been solid and solid financial data as a verification, more firmly convinced the industry's confidence in the LED industry trends. The LED industry is in short supply, and the economy is expected to last at least 2-3 years. Recently, Guoxin Securities has extensively exchanged research and research on the LED industry chain, and continuously verified the supply and demand of the LED industry. International giants such as Osram also said that LED chip supply is in short supply, while LED chip makers Jingdian, Sanan Optoelectronics, Huacan Optoelectronics, Aoyang Shunchang and Dehao Runda all said that demand for strong demand is in short supply. The main reason is that the MOCVD machine is being phased out in 2010-2011, and the number of models accounts for about 1/3 of the total. It is estimated that the annual elimination in the next 2-3 years will account for 5% to 10% of the current total capacity, about 5 million- 10 million pieces. With the increase of downstream lighting demand by more than 20% and the shortage of small-spacing demand, the annual demand for new LED chips will increase by 10 million. According to statistics, the total effective capacity at the end of 2017 will be about 83.28 million pieces, and the demand will exceed 92.35 million pieces, which will continue to be in short supply in the next 2-3 years. The LED industry data is improving, which reflects the general trend of global LED manufacturing shifting to China. The general trend of global LED manufacturing shifting to China is beyond doubt. The Chinese electronics industry has fully possessed excellent process control and cost management capabilities in the years of accumulation. At the same time, the engineers' dividends are gradually being released, prompting Chinese companies to develop and have more internationally advanced technologies with independent intellectual property rights. As international technology manufacturers encounter bottlenecks and slow down, Chinese companies will make full use of national policies and industrial capital. Engineers' bonuses and other advantages, to achieve post-production, will eventually defeat the traditional international manufacturers, and become the trend of the industry.
