PREFACE

.

It is possible that theoretical knowledge can be fully obtained in classroom,

but practical knowledge can’t be found printed in books. For the point of view of

students like us, to get just a degree does not help. In this 21st century, students need

to be marketable i.e. having enough know how about the practical things.

Our training has undergoing at “RAJASTHAN STATE MINES &

MINERALS LTD.” For 60 days between 4th June to 3rd August, 2015. In over

report we would like to cover all the information, which are required in plant

training.

We have tried our best to present this report in such a way that if

would give the required information and meaningful idea about the

industry that we have visited.

DOZER

5.1 INTRODUCATION:

The dozer, which is one of the most construction projects, is primarily

a pushing unit. This is multipurpose machine and can perform a number of

operations through specific designs like dozer, push dozer and tree dozer.

Basically a dozer is a pusher blade attached to the front portion. This is the

diesel operated power unit equipped with crawler chains. The pusher blade is

rectangular at the bottom edge, concave shaped and sloped backwards. The

pusher blade can be raised or lowered or lilted through small angles

horizontally by hydraulic arrangement. The bulldozer scrapes up soft and

granular material. It is best suited where pushing with a high force required.

31

A Dozer is used for following purpose:-

Digging the soil.

Gathering the digged soil.

Gathering the boulders.

Leveling the surface.

Spreading the soil or murrum.

In making path and rods.

CRUSHING PLANT

In R.S.M.M. Ltd. There are two crushing plants:

(a.) Low grade ore crushing plant (LPO)

(b.) High grade ore crushing plant (HGO)

6.1 (a.)Low grade ore crushing plant (LPO)

Low grade ore obtained from open cast mines are feed in this plant.

The ore usually contains 16 – 19% of P2O5. This low percent is

made rich up to 34% of P2O5. adding some ingredients. For

enrichment of ore an IBP plant is installed. In LPO cone crushing

is used & double face jaw crushing are used.

6.2 (b.)High grade ore crushing plant (HGO)

There are two HGO crushing plants –

(1.) Old crushing plant of capacity 120 / tones / hr installed in 1972

(2.) New crushing plant of capacity 180 tone / hr installed in 1992.

From open cast mine we get different percent of P2O5. Rock

phosphate, which is sold in market, should contain at least 34%

P2O5. Rock phosphate obtained from crushing plant usually

contains 31% of P2O5. as it is feed by high grade ore of Jaw crusher

is used in HGO plant.

INDUSTRIAL BENIFACTION PLANT

7.1 INTRODUCTION

Locking to the scare rock phosphate resources in india, RSMML has

put continuous effort for utilization of its low grade ore resources, which are

abundant of at Jhamar Kotara but require benefaction before its utilization by

fertilizer industries as raw material. Intensive research was carried out for ten

year and a brake through in processing technology was achieved when this

LGO was enriched to produce a very high – grade concentrate (+34% P2O5),

rated as equal to or better than any naturally accruing on this technology. From

reserves conservation point for processing of 4.25 LT of low – grade ore per

annum. RSMML plants to enhance the beneficiation to 0.85 million tons per

annum of LGO. The company has expanded the beneficiation to 0.85 million

tons per annum of LGO. The company has expanded the plant capacity to

3000MT per day.

CONCLUSION

Rajasthan state mines and minerals ltd. Is a leading rock Phosphate

producing mines and it is under taken by govt. of Rajasthan. Rock Phosphate

is mine here and the ore is treated here to provide high grade and low grade

ore.

It has very wide area and has a no. of vehicle for transportation of ore

and other material and also for transportation of man power. It also has large

no. of heavy earth moving equipment and their maintenance shops.

Good relations exists between labor and management few dispute as

strike was not taken place since many years. Through the plants is constructed

as per strike. Planning but some lacuna do remain.

Transportations roads are not very well. The production would suffer

due to sudden break down of some heavy earth moving equipment and witch

take time for preparing. Do quick and mechanic engineers and required proper

and quick maintenance and new automobile change can improve the efficiency

to plant.

Hera I got a good co-operation by the staff and workers at various

shops.

We wish all the success for the company and hope it’s excellent

performance.
