Specification of rotary kiln for 100ton sponge iron plant

Introduction of Specification of rotary kiln for 100ton sponge iron plant

A rotary kiln is a kind of industrial equipment used for material heating and processing, which is widely used in cement, metallurgy, chemical industry, etc. Specification of rotary kiln for 100ton sponge iron plant refers to various parts and components which are necessary for maintaining and repairing the normal operation of the rotary kiln, such as cylinder, baffle wheel, pallet, sealing device and so on.

Features and advantages of Specification of rotary kiln for 100ton sponge iron plant

High-temperature resistance: Due to the extremely high temperature of the working environment of the rotary kiln, the spare parts are usually made of refractory materials or special alloys to ensure that they can work stably under high temperatures.

High abrasion resistance: Long time material friction and chemical erosion require spare parts to have excellent abrasion resistance to prolong service life.

High structural strength: in order to withstand heavy loads and the pressure of continuous operation, the design of spare parts will place special emphasis on structural strength and reliability.

Easy to install and maintain: Considering the need for frequent replacement, many spare parts are designed to be simpler and easier for quick installation and maintenance.

Strong adaptability: different industries have different needs for rotary kilns, so spare parts need to have good versatility and adaptability to meet diverse application conditions.

Specifications of Specification of rotary kiln for 100ton sponge iron plant

This rotary kiln is for making sponge iron. It handles 100 tons each day. The kiln is big. It is about 45 to 50 meters long. Its inside diameter is roughly 3.6 to 4.0 meters. This size is important. It gives enough space for the materials to react. The kiln shell is made from strong steel plates. These plates are thick. They can handle high heat and pressure. The kiln turns slowly. Its rotation speed is usually between 0.5 and 1.5 revolutions per minute. This slow turning mixes the materials well. It helps the chemical reactions happen properly.

Heat is vital for making sponge iron. This kiln operates at high temperatures. The hottest part inside reaches about 1050 to 1100 degrees Celsius. This heat level is needed. It reduces the iron ore to sponge iron. The kiln uses fuel. It could be coal, gas, or other suitable fuels. The fuel burns inside the kiln. This creates the necessary heat. A good burner system is fitted. It controls the flame and the heat spread.

Powering the rotation needs a strong drive system. An electric motor is used. It connects to a gearbox. This gearbox turns a large pinion gear. The pinion gear engages with a gear ring on the kiln shell. This setup turns the heavy kiln smoothly. The kiln sits on support rollers. Tyres are mounted on the shell. These tyres rest on the rollers. Thrust rollers keep the kiln from moving sideways.

Inside the kiln is lined with special bricks. This is the refractory lining. These bricks protect the steel shell. They withstand the extreme heat inside. The lining is thick. It lasts a long time before needing replacement. After processing, the hot sponge iron comes out. It goes into a cooler. The cooler quickly reduces the temperature. This stops further unwanted reactions.

Applications of Specification of rotary kiln for 100ton sponge iron plant

This rotary kiln is built for making sponge iron. It handles 100 tons each day. The kiln is big enough for the job. It is long and has a wide diameter. This size lets material move through correctly. The kiln spins slowly. This turning mixes the iron ore and coal. Good mixing is needed for the reaction.

Heat is very important. The kiln reaches high temperatures. These temperatures change the ore into sponge iron. We use special bricks inside. These bricks hold up against the heat. They also last a long time. This saves money on repairs.

The kiln has strong seals at both ends. These seals stop air from getting in. Too much air can ruin the sponge iron. We control the air carefully. Good seals keep the process working right.

We monitor the temperature all the time. Sensors check it along the kiln. Operators watch these readings. They adjust the heat if needed. Keeping the right temperature is key for quality sponge iron.

The outside shell is thick steel. It supports the whole structure. It also keeps the heat inside. This saves energy. The kiln sits on strong rollers. These rollers let it turn smoothly. Big motors drive the rotation. They are reliable for constant operation.

Maintenance matters. Easy access points are included. This lets workers check parts quickly. Regular checks prevent big problems. The kiln is built for tough conditions. It runs day after day. Production needs to be steady. This design delivers that.

Efficiency is a big plus. This kiln uses fuel well. Lower fuel costs help the plant. It also makes good sponge iron. The product meets quality standards. Customers want reliable material. This kiln helps provide it.

5 FAQs of Specification of rotary kiln for 100ton sponge iron plant

Here are five common questions about the rotary kiln specifications for a 100-ton sponge iron plant:

What size is the rotary kiln?
The kiln is a large, rotating cylinder. Its internal diameter is typically between 3.6 and 4.0 meters. Its length usually falls in the range of 60 to 70 meters. This size provides the needed volume for processing the raw materials. It also ensures the material spends enough time inside for reduction.

What is the kiln lined with?
The inside of the kiln is protected by refractory bricks. These bricks withstand very high temperatures. They resist chemical attack from the process materials. Different types of refractory bricks are used in different zones. High-alumina bricks are common in the hottest areas. Basic bricks might be used where slag forms.

How hot does the kiln get?
The kiln operates at high temperatures. Different zones have different temperature requirements. The preheating zone starts around 800 degrees Celsius. The reduction zone reaches the highest temperatures. This zone operates between 1050 and 1100 degrees Celsius. The discharge end cools the material down somewhat.

How is the kiln rotated?
The kiln turns slowly. Its rotation speed is controlled. A powerful drive system handles the rotation. This system includes electric motors, gearboxes, and large pinions. The rotation speed is usually adjustable. Speeds between 0.4 and 1.2 revolutions per minute are typical. This slow rotation allows the material to tumble properly.

How is material fed and discharged?
Raw materials enter the kiln at the elevated feed end. A feed chute or screw conveyor usually handles this. The reduced sponge iron exits at the lower discharge end. A discharge housing surrounds this end. A cooler receives the hot sponge iron immediately after discharge. Sealing systems prevent air leaks at both ends.
