Specifications of 4.0x90m rotary kiln used for metallurgical industry

This 4.0 x90m rotating kiln manages demanding metallurgical processes. Its core is a large steel cyndrical tube. The cyndrical tube is 4 meters throughout within. Its total size is 90 meters. The covering makes use of thick, high-strength steel plates. This makes sure architectural stability under hefty loads. The inner surface gets lined with unique refractory bricks. These blocks stand up to extreme warmth and chain reaction. They safeguard the steel covering. The kiln runs at very heats. It can get to over 1200 levels Celsius. This warm is essential for refining steel ores and concentrates.

The kiln turns slowly. It requires solid drive systems. The major drive utilizes an effective electric motor. A heavy-duty gear reducer connects to this motor. The reducer lowers the electric motor rate. It raises the transforming pressure. This system turns the entire kiln body. A backup drive is typical. It maintains the kiln moving if the major drive falls short. This prevents damages from uneven heating.

Big steel tires sustain the kiln’s weight. These tires ride on pairs of rollers. The rollers are installed on solid foundation bases. Thrust rollers keep the kiln positioned properly. They stop it moving also much along its axis. Seals are essential at both ends. They prevent warm gases and dust getting away. They likewise quit undesirable air entering. Great seals improve performance. They make the process more secure as well.

The kiln tilts slightly downhill. This aids material move from the feed end to the discharge end. Product goes into through a feed chute at the high end. Refined material leaves at the lower end. Burners fire into the kiln near the discharge. They supply the extreme warmth. Advanced control systems take care of the procedure. They check temperature, rotation rate, and gas flow. Operators adjust these for best results. Security systems are integrated. They include alarms and emergency quits. This safeguards both individuals and devices. The design prioritizes reliable, constant procedure under hard problems.

Applications of 4.0x90m rotary kiln used for metallurgical industry

This 4.0 x90m rotating kiln takes on laborious in the metallurgical sector. Its plus size and robust style take care of heats and constant operation. Ore processing counts greatly on this tools. The kiln carries out calcination, driving off unpredictable elements like carbon dioxide from limestone or various other minerals. This step prepares products for more smelting. Reduction procedures happen inside also. The kiln transforms steel oxides right into functional steel making use of minimizing agents at controlled warmth. Roasting sulfide ores is an additional essential job. This process changes the ore’s chemical type, making steel removal less complicated later. The kiln manages diverse products successfully. Processing iron ore pellets before blast furnace usage prevails. Non-ferrous metals like zinc, lead, and copper gain from its capabilities. Recovering valuable steels from waste materials or low-grade ores is feasible. The kiln promotes heat-releasing procedures for certain materials. Improving ore top quality with thermal treatment is conventional technique. Its lengthy 90-meter length makes certain products get enough time inside. Sufficient home time is essential for total chemical reactions. Consistent warm distribution across the huge diameter is critical. Constant results depend on this thermal security. The design promotes reliable fuel usage and lowers operating expense. Taking care of abrasive materials is developed into its construction. Wear-resistant cellular linings extend life span considerably. Operators value its integrity for large production. The kiln integrates efficiently into existing metallurgical plants. It satisfies the requiring requirements of contemporary metal manufacturing.

5 FAQs of 4.0x90m rotary kiln used for metallurgical industry

What does this rotary kiln actually do?
It heats materials extremely hot. This changes their chemical or physical state. Metallurgical plants use it for processes like roasting ore or calcining concentrates. The high heat drives off moisture or volatile parts. It prepares materials for the next smelting step.

What materials can it handle?
It processes many metallurgical feedstocks. Common ones are iron ore pellets, nickel laterite ore, chromium ore, manganese ore, and various mineral concentrates. The kiln handles materials fed as powders, granules, or small lumps. The feed system pushes them steadily into the rotating drum.

How hot does it get inside?
The temperature reaches very high levels. It typically operates between 800°C and 1200°C. The exact needed temperature depends on the specific material and process goal. The burner system provides precise heat control. This ensures consistent processing results every time.

What makes this kiln design strong?
Its construction uses heavy-duty materials. A thick steel shell forms the main body. Inside, special refractory bricks line the entire length. These bricks withstand intense heat and chemical wear. Powerful drive gears rotate the whole kiln smoothly. Variable speed control lets operators adjust the rotation as needed.

Is it hard to keep running well?
Regular checks are essential. Inspect the refractory lining often for wear or damage. Monitor the drive gears and support rollers. Keep them lubricated properly. Check the seals at both ends to prevent heat and dust leaks. Follow the maintenance schedule strictly. This prevents unexpected shutdowns and expensive repairs.
