1.2 RAW MATERIAL GRINDING 1.2.1 INTRODUCTION

This section covers extraction of raw material from the mill feed hoppers to the transport of raw meal product. Clay in the hopper is extracted by using Apron conveyor that is synchronized with weighing feeder for clay and then weighed by the weighing feeder. Limestone, high silica and Laterite in the hopper are extracted and weighed by weighing feeders underneath each hopper. Materials weighed by weighing feeders are fed to belt conveyor and transported to the Raw Meal Grinding Section. Magnet separator is installed on the belt conveyor and ferrous foreign objects are separated from raw materials. Mixed materials are dried and ground in the raw grinding mill simultaneously. Fine material separated by classifier are collected by the cyclones and electrostatic precipitator (raw mill EP) and transported to the blending silo feeding section. Over sized materials which are not ground enough in the raw mill is discharged from raw mill and fed to the raw mill again together with new feed material. Feeding quantity of raw materials to raw mill is controlled by using the ampere of raw mill main motor or the pressure of raw mill inlet. Operating hydraulic pressure is adjusted by operator manually in accordance with raw mill operating condition. To detect the ferrous and nonferrous metal in the raw materials, metal detector is provided on the mill feed belt conveyor. When metal detector detects the foreign metals, foreign metals are rejected from the process line by changing the direction of two way chute provided at outlet of belt conveyor. Exhaust gas from the suspension preheater is used as the heat source for drying of material. Hot gas generator is provided for produce the heat source for drying of material, in case that heat source from suspension preheater is not enough. Combustion capacity of hot gas generator is controlled to keep the temperature of mill outlet. Opening ratio of control damper for secondary fan (dilution fan) is controlled to keep the temperature of hot gas generator outlet.

1.4 CLINKER BURNING 1.4.1 INTRODUCTION

This section covers extraction of raw meal from blending silo to the transport of clinker to the top of clinker silo. The raw meal in the blending silo is extracted from the flow control gates at the lower part of the silo and stored Kiln feed bin. The flow control gate openings are controlled to keep the level of Kiln feed bin constant. The raw meal stored in kiln feed bin is aerated by open type air slide provided on the bottom of the bin and extracted via flow control gate. Then extracted raw meal is weighed by impact flow meter. By using the measuring flow rate at impact flow meter, opening ratio of flow control gate is controlled by LCP of impact flow meter. Specified raw meal weighed by impact flow meter is transported to the top of SP tower via air sliding conveyors and belt type bucket elevator. A circulation system is established to return the raw meal to the blending silo by changing the route of 2 way chute provided at the outlet of the bucket elevator. The raw meal fed to the connection duct of cyclones between C5 and C4 is calcined in it up to 85-90% of decarbonation rate, then this highly decarbonation raw meal is fed to rotary kiln for the remaining decarbonation and clinkerization. The high temperature part of exhaust gas from the kiln outlet hood is induced to the swirl burner and swirl calciner of suspension preheater for utilizing as secondary air for burning. The exhaust gas from suspension preheater is used for drying of raw materials during raw grinding mill is operated. When the raw grinding mill stops or run in less moisture content of raw materials, the exhaust gas from suspension preheater is cooled in the gas conditioning tower so as to keep the good dedusting efficiency in electrostatic precipitator (raw mill EP). Dedusting dust at raw mill EP and gas conditioning tower are returned to bucket elevator for feeding to blending silo. D.O. is used for fuel for clinker burning kiln and precalciner in start-up and when coal quantity is inadequate or in case of trouble. Pulverized coal is used for fuel for clinker burning kiln and precalciner in normal

operation. Pulverized coal stored in the bins are extracted by horizontal rotary feeders and measured by rotary scales. To keep the smooth extraction from pulverized coal bins, agitators are provided at the bottom of the bins. Measured pulverized coal is transported to the burners for suspension preheater and kiln by pneumatic conveying system. The high temperature clinker discharged from rotary kiln is cooled rapidly by grate type clinker cooler and sent to top of clinker silo by metallic conveyor. For cooling the clinker, cooling fans are provided on the both side of clinker cooler. To prevent the accumulation of clinker under the discharge part of rotary kiln, air cannons are provided at the inlet part of clinker cooler. Lumps of clinker are crushed by hammer type crusher located on the end of clinker cooler. Spillage of clinker dust is collected in the hoppers underneath the cooler grate and discharged to metallic conveyor via discharge gates. For dedusting the exhaust gas from clinker cooler, electrostatic precipitator (cooler EP) is provided. Collected dust at the electrostatic precipitator is returned to metallic conveyor for feeding to clinker silo. The dedusted gas from clinker cooler is utilized for coal grinding section for drying the raw coal. These operations of this section are carried out from the control station provided in CCR. But the kiln burner and SP burner ignition and inching operation of kiln are performed from the local control panel of the machine side.
