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 Jhamar kotra, Udaipur. Mining and basification of low grade rock phosphate to

produce high grade rock phosphate concerned at its IBP at Jhamar kotra , Udaipur.

Manufacturing and selling of low grade ore as phosphate fertilizer called RAJPHOS for direct application.

VOCATIONAL TRAINING CENTRE

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.

DRILL RODE SIZE:

length : 7.62m

Diameter : 152mm (6”)

Total drill depth : 30.48m (100”)

Number of rods : Four

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.
