rotary kiln bauxite used to bulid bauxite rotary kiln factory

The rank of countries alumina bauxite storage is: Australia, The Republic of Guinea, Jamaica, China, and India. Rich reserves provinces in China are Shanxi, Guizhou, Guangxi and Henan province. Generally, alumina bauxite is used to produce alumina or aluminum.

Bauxite rotary kiln consists of steel shell, tire, drive gear, kiln hood, kiln seal, burner pipe. Kiln head guard and kiln tail return spoon are built-in block casting, so bauxite rotary kiln has many advantages like easy installation, high heat, corrosion and wear resistance. Kiln head-cold air cover ventilating with cold air makes kiln safer and more reliable by evenly cooling down kiln head, barrel and kiln mouth shield. More stable airflow profits from large volume kiln hood and split kiln door. Adopt the most advanced double seal technology in the world, which is radical friction maze seal and scales seal. This kind of seal form has a simple structure and is easy to maintain. The combustion device adopts a swirling four-channel pulverized coal burner with a burner pipe.

How to deal with the heating problem of roller tile on bauxite rotary kiln:The heating problem consists of heating thrust surface, heating roller tiles surface and both of them. To highlight the adjustment effect, push forward a roller tile in one pair while pulling back the other, but it cant suitable for the circumstance when the pair of them are both heatings. In case of the change of kiln centerline, you can adjust the wheel seat located in diagonal. After the adjustment, inspect the gap between thrust plate and roller tile and the temperature of roller tiles.

industrial minerals networking | imformed china minerals 2019: bauxite & magnesia mid-year report

Towards the end of 2018 we reviewed the outlook for China refractory minerals and considered what the impending Year of the Pig had to offer (see Chinas refractory mineral supply a New World: review & outlook).

Despite a freeing up of some supply and lowering of prices during the early part of 2019, especially for magnesia, come the mid-year point and all is very different and, typically, uncertain. Indeed, the Year of the Pig seems very much set to live up to its name for the rest of 2019.

Eight teams were dispatched to the six provincial-level areas of Shanghai, Fujian, Hainan, Chongqing, Gansu and Qinghai, as well as the two SOEs China Minmetals Corp. and China National Chemical Corp.

In June, the Ministry of Ecology & Environment publicly accused many companies of exceeding pollution limits, including subsidiaries of some the biggest state enterprises like China Baowu Steel Group and the Aluminium Corp. of China.

Moreover, with the upcoming all-important celebrations on 1 October 2019 for the 70th Anniversary of the founding of the Peoples Republic of China, the government is adamant to impose whatever industrial restrictions are necessary in order to maintain a clean air environment for the beginning of October.

This has resulted in not only more environment inspections and resulting plant closures, but another new ban on explosives use by miners particularly impacting the magnesia industry in Liaoning province.

And if, as is widely anticipated, the government also later insists on what is becoming an annual routine of an industry shutdown or reduction in capacity use over the winter months, then this would effectively curb industrial output all the way through to end-March 2020.

The main talking point however, is whether a new bauxite mine will soon start up in Shanxi province, much discussed since 2018 (whatever happened to the proposed refractory industrial park, with bauxite supply exclusively for refractories? see China minerals supply outlook: Shanghai showdown). This would greatly relieve supply issues and perhaps ease upward pressure on bauxite pricing.

Vincent Wong, Business Manager, Refractories Window, told IMFORMED: We learnt that the new mine has been authorised, and is only waiting to start, but the question is when will it start in Xiaoyi? Some local participants said the new mine has started and ore output is very small scale, but others deny this. Many people said the original mine [Xiangwang] will stop soon, but some people dont think so.

So thats all clear then. What is clear is that there are continuing environmental inspections in the province, with some bauxite plants upgrading their equipment, a few reported in operation, while many are likely to remain closed. I think there might be more that will be shut down in the second half of this year. said Wong.

In Henan province, although under less pressure from environmental protection regulations compared to Xiaoyi, Shanxi, the calcined bauxite and brown fused alumina (BFA) sector is not faring any better.

Recent BFA plant closures have included plants in Dengfeng, Henan, Henan Province Yima Xinrui Fire-Proof Material Co. Ltd, Guizhou Kaiyang Sanhuan Abrasive Materials Co. Ltd, Shanxi Taiyue Abrasive Co. Ltd, and most white fused alumina plants in Xingyang, Henan.

This has also affected the aluminium industry of course. In June, alumina prices in northern China hovered around six-month highs as sudden environmental shutdowns in Shanxi province raised concerns about supply.

In addition to simply not enough domestic supply, often the Chinese bauxite (mostly of diaspore variety) is not ideally suited to make smelter grade alumina, which is another reason why China is greatly increasing its bauxite imports.

In May 2019, China recorded a 135% increase in imports of alumina at 55,066 tonnes, and 27% increase in bauxite at 9m. tonnes, corresponding exports of the materials were 7,536 tonnes (down 91%) and 4,473 tonnes (up 9%), respectively.

In July, Metro Mining Ltd, already supplying metallurgical bauxite to China from its Bauxite Hills Project near Weipa, Queensland, Australia, announced a contract with state-owned China Aluminium Corp. (Chalco) to deliver 420,000 wet metric tonnes of bauxite in the second half of this year, and has plans to double production to 6m.tpa.

Regarding non-metallurgical bauxite, Bosai Group, based in Chongqing, China, earlier this year announced a US$23m expansion plan for its Linden bauxite operations in Guyana operated by Bosai Minerals Group Guyana Inc. (BMGG).

This includes a new no.15 rotary kiln for 170,000 tpa RASC refractory grade bauxite (to eventually replace the old no.13 kiln) and a new no.16 drier and auxiliary facilities to produce 150,000 tpa chemical grade bauxite.

The main magnesite mine in Haicheng, Liaoning province appears to be facing a three month closure from 1 August to 31 October. Although, earlier reports indicated mining had already stopped in mid-June.

In any case, news of the mining halt has apparently slowed the downward trend in magnesia prices as consumers scurried around to order what they could before primary ore feed ceases to the magnesia plants.

The mine operator, Liaoning Magnesite Mining Co. (LMMC), is the entity representing the ongoing integration of the Liaoning magnesite supply sector which apparently now has up to 28 shareholders including a 51% holding by SASAC Haicheng (local provincial government).

The mining halt has come about in an effort for the local government to control its overproduction. However, observers might view the move as simply a way to firm up prices, and also with a dynamite ban apparently coming into play on the run up to 1 October it would seem some stoppage in mining was inevitable.

Elsewhere in China, Puyang Refractories Group Co. Ltd (PRCO) subsidiary Qinghai Punai Magnesite Material Co. has commenced pilot plant production of macrocrystalline fused magnesia and high purity magnesia.

Another PRCO subsidiary, PRCO High Purity Magnesia Refractories Co. Ltd, is opening a new 1m. tpa mine in Tibet. The Kamaudo deposit in Rioche county, Changdu is some 50m tonnes reserves of high purity magnesite grading 47.6% MgO with low iron and silica. The site was first developed by Huayin Group in 2007 before it became part of PRCO.

The new rotary kiln has a capacity of 60,000 tpa DBM (and CCM) products and can supply refractories and other industrial applications such as welding fluxes, leather tanning, friction materials, and heating elements.

Emanuel Tsontakis, Managing Director, Ternamag told IMFORMED: In general, our DBM strategy is the same as with CCM, and is not based on what the Chinese do, and focuses equally, if not more, on the non-refractory applications market, which is by far more stable and allows for better margins.

Its a strange, if frustrating time for refractory mineral buyers. The outlook for Asia, especially India, and MENA is promising, while the developed markets the West (excepting Turkey and Eastern Europe) appear very slow with little or any growth (see chart).

Take Imerys for example, supplier of aluminosilicate materials and owner of refractory producer Calderys. At its recent H12019 investor presentation, Olivier Pirotte, CFO acknowledged that: Iron and steel production has turned negative in Europe with production volumes worsening to minus 4.3% in Q2 from a decrease of 0.5% in Q1.

Conrad Keijzer, CEO, summed up with: What happened in the iron and steel industry is that in the first quarter, the furnaces were all still running and actually there was an inventory build, basically across all of the major iron and steel manufacturers in Europe. In the second quarter, you saw several announcements of capacity being taken out of the market and that is explaining the lower production rates in the second quarter affecting our high-temperature materials business.

World no. 2 refractory producer Vesuvius was somewhat more forthright with its take on the first half: We have experienced challenging end markets in H1 2019 and we do not expect a recovery in H2 2019. Vesuvius Steel Division reported revenues of 614.9m in H1 2019, an increase of 0.6% compared to H1 2018.

With refractory producers having plenty of inventory of raw materials and end products (as much as 6-9 months worth), it is little wonder that they are refraining from purchasing any more raw materials.

The frustration for the procurement managers of Europes refractory companies (and Chinese refractory mineral suppliers for that matter), is that they are not being permitted to take advantage of Chinese refractory raw material prices having come down to a relatively lower level (especially for magnesia) over the last 12 months.

They are extremely keen to snap up stocks at this time, however, this is cutting little ice further up the management chain as steel remains in the doldrums. The situation in North America, with a slightly better steel performance, is less severe.

As the summer wears on, and autumn and winter loom large, attitudes may start to change as the ramifications of the latest dynamite ban, ongoing environmental controls, Liaoning magnesite mining control (whether to influence prices or for pollution control), and the threat of another October to March industrial shutdown, start to coalesce and impact the market.

We may well see an end of year rush, or perhaps more conservatively, a canter, to secure raw material for 2020. And, if there is a near term recovery in refractory markets, although unlikely, the canter will turn into a gallop.

Excellent summary and review of the China situation. Especially appreciate the update on bauxite, a sector which has been through enormous changes. New suppliers from Australia which i follow closely will continue to be at the forefront of low-silica grades. Rgds Murray Lines PS Looking forward to catching up at Mumbai in November.
