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.

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.

SHOVEL SECTION

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 .

Dimensions of Excavator

TERMINOLOGY OF EXCAVATOR

SPECIFICATION: Model Pc 1000-1/BE-1000 Operating weight 98,000Kg

TRAVEL SPEED: Low 2.4 km/hr High 3.4 km/hr Swing speed 4.5 rpm Engine Rated rpm 1700 rpm Flywheel 542 HP

DUMPER SECTION

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.

DRILL SECTION

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

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.

Dimensions of Blast Drill

DRILL RODE SIZE: length : 7.62m Diameter : 152mm (6”) Total drill depth : 30.48m (100”) Number of rods : Four

TERMINOLOGY OF BLAST-HOLE DRILLING

CRUSHING PLANT In RSMML ltd there are two

crushing plants: (a) Low grade ore crushing

plant(LGO) (b) High grade ore crushing

plant(HGO)

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.

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.

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.

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.
