Titanium concentrate is a titanium dioxide (TiO₂)-rich ore extracted from ilmenite or titanomagnetite, typically with a TiO₂ content between 40% and 50%. As a key raw material for the production of titanium products such as titanium dioxide and titanium sponge, titanium concentrate requires crushing and processing to meet subsequent process requirements. Raymond mills have broad applicability in titanium concentrate processing. The following section will provide a detailed analysis of their process compatibility, equipment advantages, optimization improvements, and practical applications.
1. Process Compatibility
The acid hydrolysis reaction of titanium concentrate requires a fineness of 325 mesh, a sieve residue of ≤1.5%, and a uniform particle size distribution. Raymond mills, as dry mechanical pulverization equipment, utilize the compaction action of rollers and rings and a pneumatic classification system to consistently produce products that meet the required titanium concentrate particle size. The typical process flow is as follows:
Titanium concentrate → bucket elevator → silo → feeder → Raymond mill → cyclone separator → pneumatic conveying → ore powder storage tank
The Raymond mill plays a central role in this process, precisely controlling the grinding process to achieve efficient pulverization and maintain consistent particle size.
2. Equipment Advantages
High Efficiency and Low Energy Consumption: Compared to universal grinders and air jet mills, Raymond mills offer the advantages of high output and low energy consumption per unit. For example, the 4R3216 Raymond mill is widely used in titanium dioxide production plants. As production capacity demands increase, the design of the Raymond mill has been upgraded to the GKLM series vertical mill.
Particle Size Control: Raymond mills are equipped with a built-in classifier that dynamically adjusts the powder fineness (80-600 mesh), ensuring a uniform finished product with minimal coarse particles, meeting the standard requirements for concentrate powder.
Wide Applicability: Raymond mills are suitable for materials with a Mohs hardness of 7 or less (such as ilmenite) and can process materials with a moisture content of no more than 6%, meeting the requirements of most titanium concentrate processing processes.
3. Improved Raymond Mill Optimization
To address the shortcomings of traditional Raymond mills in powder collection efficiency, the new equipment has enhanced performance through the following design optimizations:
Sorting Mechanism: The new sorting system effectively improves the accuracy of fineness sorting, ensures particle uniformity, and meets higher precision requirements.
Negative Pressure Circulation System: The bag dust collector recovery system reduces fly ash loss, further improving material recovery and optimizing production efficiency.
These optimized designs make Raymond mills more efficient and environmentally friendly in titanium concentrate processing, and help reduce operating costs.
4. Practical Application Examples
Titanium Dioxide Production: Raymond mills are widely used for primary pulverization of ilmenite (particle size 325 mesh) and pulverization after calcination of metatitanic acid. In the titanium dioxide production process, Raymond mills help factories achieve a more uniform particle size distribution and improve the acid hydrolysis rate by adjusting process parameters (such as analyzer speed).
Process Optimization Case Study: A titanium concentrate concentrator optimized the powder particle size distribution and improved the process flow through adjustments to its Raymond mill. Ultimately, this resulted in efficient pulverization and high-quality production of titanium concentrate, meeting the consistent and stable fineness requirements of subsequent processes.
Raymond mills are an ideal choice for titanium concentrate processing due to their high efficiency, low energy consumption, and easy control of particle size distribution. Through targeted improvements, Raymond mills can better meet the process requirements of titanium concentrate pulverization and provide strong support for the production of titanium products such as titanium dioxide and titanium sponge. Their adaptability, energy efficiency, and optimized design make them an indispensable piece of equipment in modern titanium concentrate processing.
