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.
