Sri Lanka iron concentrate drying project

April 20, 2022

Project introduction: The project is located in Sri Lanka. The owner is an enterprise engaged in deep processing of titanium powder. In order to develop new products, customers hope to calcine their existing titanium powder and constantly experiment to obtain ideal finished products. Because it is the experimental stage, the amount of materials that customers need to calcine is small, which is 30 kg / h. The material calcination process involves multiple processes, which is a calcination process that needs systematic design. After determining the site conditions and technical requirements of customers, we provide customers with the combination scheme of rotary kiln and gas burner. The customer is very satisfied with our professional technology and service level. I hope we can recommend appropriate experimental equipment according to the needs of the project. After confirming the customer's front and rear processes, we will determine the specific model and size for the customer.

[Raw material] Titanium concentrate

[Fuel] Natural gas

[Production capacity] 30kg per hour

 

Project overview

Project address: Colombo, Sri Lanka

Product Name: Titanium concentrate experimental rotary kiln

Production scale: 30kg/h titanium concentrate drying line

Service scope: From the storage, transportation, calcination and dust removal of titanium refined powder raw materials to the process design, equipment supply, equipment installation and commissioning, after-sales training of finished product storage and transportation system, environmental dust collection system and electrical automation control system.

 

Project Solution

At first, the customer only provided basic information, including that the material to be calcined is titanium powder, the calcination amount is 30 kg per hour, and the fuel used for calcination is natural gas. Obviously, these data can not support the process design. After many inquiries and communication, the customer provided important calcination temperature and calcination time. The customer hopes to calcine for 2 to 3 hours, and the required calcination temperature is 950 to 1050 degrees. Do experiments in such a calcination environment to observe whether the finished products can meet the demand. Based on the customer's data, our technical team selected the rotary kiln with a diameter of 0.5m and a length of 4m as the main equipment to complete the calcination demand after careful calculation. On this basis, provide customers with dust removal system and transportation equipment.

The initial materials enter from the head of the rotary kiln through the conveying equipment φ The 0.5 * 4m rotary kiln flows downward from the inlet under the action of gravity. During the rotation of the cylinder, the materials are constantly overturned in the cylinder and gradually heated. The preheated material continues to move to the high-temperature area. In this process, the material is calcined to a high-temperature state, and its shape is also changing.

The flue gas in the rotary kiln is led out from the upper part of the kiln tail. Under the action of the induced draft fan, the flue gas passes through the dust collector and then discharged from the chimney through the fan.

The calcined titanium concentrate reservoir product flows out from the tail of the rotary kiln and is delivered to the storage area through the conveyor. During transportation, contact with the natural environment can help cool the finished product. After cooling, customers will study how to optimize the calcination process according to the situation of finished products to promote the calcination effect.
