Use of Conical Mill
A conical mill is a machine used to reduce the size of materials using centrifugal force. The mill consists of a rotating impeller and a fixed conical screen. The material to be milled is fed into the mill through a feed hopper. The impeller accelerates the material and forces it against the conical screen. The particles that are small enough to pass through the screen are discharged from the bottom of the mill, while the larger particles are retained and continue to be milled.
The Conical Mill operates on the principle of centrifugal force to achieve precise and controlled size reduction of materials. Its key components and functioning include:
Feed Hopper: The process begins with the material being introduced into the mill through a feed hopper. This hopper can be designed with various features like vibration or screw feeders to ensure consistent material flow.
Rotating Impeller: At the heart of the mill is a high-speed rotating impeller. This
impeller serves multiple functions:
- It accelerates the incoming material, imparting kinetic energy.
- Creates a vortex that draws material towards the milling zone.
- Provides initial impact for breaking larger particles.
Conical Screen: Surrounding the impeller is a fixed conical screen. This screen is a
critical component:
- Its conical shape creates a graduated milling zone, with coarser milling at the top and finer milling
towards the
bottom.
- Available in various aperture sizes to control the final particle size of the milled product.
- Can be easily interchanged to adapt to different product requirements.
Milling Action: As the impeller rotates, it forces the material against the conical
screen:
- Larger particles are subjected to impact and shearing forces against the screen.
- The conical shape creates a spiral path for the material, increasing residence time and milling
efficiency.
- Particles are continuously reduced in size until they are small enough to pass through the screen
apertures.
Product Discharge: Milled material that passes through the screen is discharged from
the bottom of the mill:
- The discharge can be designed to integrate with
subsequent processing equipment or collection systems.
- For wet milling, the discharge may include features to handle liquid-solid
mixtures effectively.
Continuous Processing: Larger particles that do not pass through the screen are
retained and continue to be milled:
- It ensures a consistent final particle size distribution.
- The continuous nature of the process allows for high throughput and efficiency.
SPECIFICATION
-
Versatile Processing Capabilities
The Conical Mill is engineered for both Dry & Wet Milling & Grating operations. This dual functionality allows manufacturers to process a wide range of materials without the need for separate equipment. For dry milling, it efficiently reduces particle size and breaks up agglomerates in powders. In wet milling applications, it can handle slurries and wet masses, making it ideal for pharmaceutical wet granulation processes or food puree production.
-
Multiple Capacity Options
Understanding the diverse needs of our clients, we offer the Conical Mill in Three Models, each designed to cater to different production scales:
- Small-scale model: Ideal for research and development, small batch production, or pilot plant operations.
- Medium-scale model: Suitable for medium-sized manufacturing facilities or companies with moderate production demands.
Large-scale model: Engineered for high-volume industrial production, meeting the needs of large pharmaceutical or food processing plants.
-
Varied Processing Rates
The three models offer a range of processing capacities to match different production requirements:
- 0-100 Kg/Hr: This lower capacity range is perfect for smaller batches, allowing precise control over the milling process for sensitive or high-value materials.
- Up to 250 Kg/Hr: The medium range offers a balance between throughput and control, suitable for most standard production needs.
- Up to 450 Kg/Hr: High-capacity processing for industrial-scale operations, enabling efficient large-batch production while maintaining product quality.
-
Enhanced Mobility
Each Conical Mill is mounted on a trolley equipped with lockable wheels. This design feature offers several advantages:
- Easy relocation within the facility, allowing flexible production line setups.
- Simplified cleaning and maintenance, as the unit can be easily moved to designated areas.
- Improved space utilization, as the mill can be stored when not in use and quickly deployed when needed.
- The lockable wheels ensure stability during operation, preventing unwanted movement.
-
GMP-Compliant Design
The Conical Mill is built to meet Good Manufacturing Practice (GMP) standards, a critical requirement in pharmaceutical and food processing industries. This GMP Design incorporates several key features:
- Use of pharmaceutical-grade stainless steel for product-contact parts, ensuring material purity and easy cleaning.
- Smooth, crevice-free surfaces to prevent product accumulation and facilitate thorough cleaning.
- Easy disassembly for cleaning and inspection, reducing the risk of cross-contamination between batches.
- Documentation and traceability features to support regulatory compliance.
-
Vacuum Operation Capability
The mill's design allows for Vacuum Operation, a crucial feature for processing sensitive materials:
- Enables processing of oxygen-sensitive compounds by creating an inert environment.
- Facilitates the milling of volatile materials by preventing loss through evaporation.
- Enhances safety when dealing with potentially explosive dusts by minimizing dust generation.
- Improves overall efficiency by reducing product loss and maintaining a cleaner processing environment.
