Working capital refers to that part of the firm s capital which is required for financing short term or current asset such as cash, marketable securities, debtors and

inventories. It is a measure of both a company s efficiency and its short term

financial health. If the working capital is positive it means the company is able to pay off its short term liabilities. If it is negative company is unable to meet its short term liabilities with its current assets. If a company s current asset do not exceed its liabilities then it may run into trouble paying back creditors in the short term. So if a company working in the most efficient manner (slow collection) it will show up as an increase in the working capital

PRODUCTION DEPARTMENT

ORGANISATION CHART OF PRODUCTION DEPARTMENT PRODUCTION DEPARTMENT

KMML always maintain high standard of perfection by achieving technical excellence in every phase of production. Catering to strict guideline, KMML offers a wide range of products for quality conscious customers. Their products go in to the manufacture of variety of products used in every day life. Paint material, facial creams, tablets, newsprint, rubber products, cosmetics and printing inks all contain TiO2 .

This department undertakes activities and decision regarding the production work. Deputy General Manager (production and maintenance) controls the activities of the department. Production of TiO2 is carried out in lot wise with specific lot number. Each lot contain 15 MT of TiO2 , samples are collected from production at specific intervals and examined thoroughly in the laboratory or the company. If any defect is identified, then the lot is considered as inferior quality.

independent production units in KMML. The TP unit is divided in to three plants. ¢ Illmenite Beneficiation Plant

¢ Acid Regeneration Plant ¢ Pigment

MINERAL SEPERATION PLANT

The MS plant was originally established in 1932 in the private sector. Several machineries were added in the course of time. This plant situated by the side of the open mines, does the separation of the minerals from the beach sand. The raw sand is first concentrated in spiral separation to enrich the heavy mineral content. The wet concentrate is then dried in fluidized bed drier and then fed to the dry separation plant. Magnetic separation and HT separation separate different minerals. The plant also separates Rutile and Zircon from the sand.

TITANIUM DIOXIDE PIGMENT PLANT

TiO2 Pigment manufacturing process of KMML based on chloride route, the process consist of following steps.

Reduction and leaching of raw illmenite of 90-92% TiO2 (illmenite Beneficiation) Regeneration of spent Hydrochloride acid for minimum pollution.

Conversion of beneficiated illmenite to TiO2 pigment ILLMENITE BENEFICIATION PLANT

Here the raw illmenite containing 58-60% TiO2 is beneficiated to 90% TiO2 content. The beneficiated illmenite is the raw material for the pigment production plant. The ferric oxide in the raw illmenite is subjected to high temperate of 8500c. The reduced illmenite then cooked and sent to digesters where it is leached with 18-20%

Hydrochloric acid. The spent leach liquor is sent to storage tanks. The leached illmenite after washing and filtering is calcined to get beneficiated illmenite. ACID REGENERATION PLANT

The spend leach liquor from the pre concentrator is processed in to the spray roaster in which the liquid spray entering the furnace is heated by the burning oil. The spend liquor then decomposes to metallic oxides and hydrochloric acid. The hydrochloric acid vapor is first cooled in pre concentrator and then absorbed in the wash liquor generated in the IBP to get 18% HCI which is recycled back to IBP. The

unobservable gases are scribbled with water before venting to the atmosphere. The metal oxide consisting of mainly iron oxide are slurred with water and routed to the slurry panel.

PIGMENT PRODUCTION PLANT

The pigment production plant has three units: 1. Chlorination plant

2. Oxidation plant

3. Surface Treatment and Pigment Finishing Plant CHLORINATION PLANT

This unit beneficiated illmenite from chlorinated as reducing atmosphere to produce Titanium Tetra Chloride (TiCl4). Chloride reacts with Titanium Chloride and other metallic oxides. Beneficiated in the illmenite in the pressure petroleum coke at a temperature of 800-900c in fluidized bed chlorination to produce chlorides are condensed and purified to obtain pure TiCl4 liquid, which is stored in the storage vessel.

OXIDATION UNIT

In this unit raw pigment grade TiO2 is produced by reacting pure TiCl4 and oxygen with at a temperature of about 1000c in a reactor after preheating the TiCl4 in a pure heater having suspended in code tubes to carry the Titanium Chloride vapor. TiO2 raw pigment obtained for this unit is scurried with water pumped storage tanks for further processing in the pigment-finishing unit the chlorine is liberated back to the chlorination unit.

Oxygen and chlorine are required for oxidation and chlorination. PIGMENT FINISHING UNIT

The unit-dispersed slurry from oxidation unit is passed through the different subsections of the unit via, sound milling and classification treatment filtration, drying, micronisation, scrubbing, cooling and bagging. In the treatment section chemicals are added. Give a coating to the pigment is reduced to two microns to be micronisation treatment. The hot micronised pigment is cooled and pneumatically conveyed to the final storage bin, this product is then bagged in paper bags of 25 kg each stacked on woolen pallets (40 bags/pallets) and dispatched.

AIR SEPERATION PLANT

This unit has been designated by M/s Lair Linde, France and supplied through M/s BHPV Ltd Visakapattanam. The Oxygen and Nitrogen are required for the process in the Oxidation and chlorination unit. This plant has a capacity to produce the

following.

1 Gaseous N2 “ 1500 Nm/hr (50 MTD) 99.8% purity 2 Gaseous N2 “ 1800 Nm/hr (50 MTD) 99.5% purity 3 Liquid O2 “ 37.5Nm/hr (2.5 MTD) 99.5% purity 4 Liquid N2 “ 45Nm/hr (2.5 MTD) 99.5% purity IRON OXIDE BRICKS PLANT

An iron oxide brick is a building material produced KMML. The materials used for the production of iron oxide bricks are:-

1. Iron oxide 2. Lime 3. Cement 4. River sand 5. Sodium silicate

The company has been facing a problem in the waste disposal areas. This problem is mainly connected with the disposal of iron oxide slurry, which has been coming outside from acid regeneration unit as a waste. In order to dispose the iron oxide powder the company started to produce the iron oxide bricks in the plant. At present the company is using this product for its domestic purpose such as constructing compound wall, floor etc.
