PACIFIC COLLEGE OF ENGINEERING, UDAIPUR (RAJASTHAN TECHNICAL UNIVERSITY) Department of Mechanical Engineering A Industrial training presentation On Rock Phosphate Mines At Rajasthan State Mines and Minirals ltd. J hamarkotra, Udaipur Submitted to: Submitted by: Department of Mechanical Engineering SHIVAM KUSHWAH 13EPAME064

2. INTRODUCTION OF COMPANY RSMML is multi mineral and multi location enterprise engaged in mining  of Rock Phosphate The company is mainly responsible for the production of rock phosphate. The very objective of the company is to achieve cost effective technological innovations in the mining of minerals. Company is focused about mining and marketing of high grade rock phosphate ore at Jhamarkotra, Udaipur. Mining and basification of low grade rock phosphate to produce high grade rock phosphate concerned at its IBP at Jhamarkotra , Udaipur. Manufacturing and selling of low grade ore as phosphate fertilizer called RAJPHOS for direct application.

3. VOCATIONAL TRAINING CENTRE VTC is the training centre which provides safety training to every member of the company. In this section training officer provides complete detail about the company. In this centre training is provided by Engineers or the managers of the company so that workers can work efficiently in their respective working areas.

4. SHOVEL SECTION

5. SHOVEL SECTION The shovels used in RSMML mines is hydraulically operated. After blasting the fragmental material it is loaded in to dumper by hydraulic excavators. It can load 10 to 12 dumpers in one hour. All shovels are of BEML company and each costs above 3 crore .

9. DUMPER SECTION

10. DUMPER SECTION Dumpers are used for the transportation purpose of raw materials. Dumpers unload the raw materials to the dumping yard ,IBP and crushing plant. Each dumper costs more than 3 crore . Currently there are 15 dumpers in the RSMML. Tubeless tires are used in dumpers.

15. DRILL SECTION

16. DRILLING SECTION Drilling on hole is the most important operation in open cast mine. There are three types of drilling machines and two compressors are available. Types of drilling machines: 1. IDM-45D - 8.5” dia 2. IBH-10 - 6” dia 3. ICM-260 - 4” dia

17. Why drilling is done? Firstly particular site is examine for drilling. After drilling is done blasting bombs are inserted in the holes. After this procedure blasting takes place and the material is loaded to dumpers by the shovels. These materials then send to crushing plants for further reducing in dimension nearer to 25 mm of size.

21. CRUSHING PLANT In RSMML ltd there are two crushing plants: (a) Low grade ore crushing plant(LGO) (b) High grade ore crushing plant(HGO )

22. LOW GRADE ORE CRUSHING PLANT Obtain from open cast mines. It contains 16% to 19% of phosphate. This low percent ore is made rich upto 34% of phosphate in an IBP plant. In LGO plant cone crusing and double face jaw crushing are used. Then the final product is dumped in the dumping yard and then sold in the market.

23. HIGH GRADE ORE CRUSHING PLANT There are two HGO plants in RSMML. (1) Old crushing plant – capacity 120 tones/hr, established in 1971. (2) New crushing plant- capacity 180 tones/hr, established in 1992. It contains 34% of phosphate and can be directly sold to the market. Jaw crushers are used in HGO plant.

24. INDUSTRIAL BENIFICATION PLANT The low grade ore which contain 16% to 19% phosphate is treated with some chemicals like phosphoric acid, sulphuric acid. Then it converted into high grade ore with 34% phosphate concentration. After this the output product is dumped in the dumping yard. From dumping yard these final product is loaded in the dumpers.

25. There can be more than 200 products made from treating this final material with different ingredient and then they can be directly used. For final product the material is given to many small companies like Rama Phosphate etc. which makes final product.
