Wheel Grinder Mixer
The wheel grinder mixer, often referred to as a wheel mill or pan mixer, is a crucial piece of equipment in the charcoal production process. Its primary function is to mix and compact raw materials, ensuring they are uniformly blended before they are fed into the molding machine.
The wheel grinder mixer is a vital component in the charcoal making process, providing an efficient and effective means of preparing materials for subsequent processing stages. The wheel grinder mixer can also be used in other industries where mixing and compacting of powdery materials are required. Including the production of certain types of ceramics, fertilizers, and various types of mineral processing.
The Structure of Wheel Grinder Mixer

Mixing Pan: The mixing pan is a circular, often shallow container where the materials are placed for mixing. It is typically made of durable materials to withstand wear and tear from constant use.
Rollers/Wheels: The wheel grinder mixer features heavy rollers or wheels that rotate around the pan. These rollers apply pressure to the materials, compacting and grinding them as they move.
Shovels/Blades/Discs: The shoves and rollers are connected together inside the mixing pan. They assist in the movement and stirring of the materials, ensuring even distribution and thorough mixing. The combined action of the rollers and shovels ensures a more homogeneous mixture.
Drive Mechanism: The rollers are driven by a motor connected to a system of belt pulleys. The belt pulleys facilitate the transfer of rotational motion from the motor to the rollers, ensuring smooth and consistent movement.
Outlet: Located at the bottom of the pan, the discharge valve allows for the easy release of the mixed materials.
Working Principle of Wheel Grinder Mixer
The working principle of the wheel grinder mixer involves a combination of rolling and stirring actions to achieve thorough mixing and compaction of raw materials.
Loading: Raw materials, including charcoal powder, binder, and water, are loaded into the mixing pan. The proportions of these ingredients are critical for achieving the desired consistency and quality of the final product. The proportions of these ingredients are pre-determined based on the desired quality and characteristics of the final product.
Mixing and Compacting: The motor activates the drive mechanism, causing the rollers to rotate around the pan. As the rollers move, they exert pressure on the materials, breaking down any lumps and ensuring thorough mixing. The rolling action also helps to compact the materials, making them more cohesive.
Stirring and Scraping: The shovels inside the pan continuously scrape the sides and bottom of the pan, lifting and redistributing the materials. This scraping action prevents the material from sticking to the pan and ensures that all portions of the mixture are evenly exposed to the rolling action of the rollers.
Continuous Mixing: The combined rolling and stirring actions continue for approximately 20 minutes. During this time, the materials are repeatedly rolled and stirred, achieving a homogeneous mixture with uniform consistency.
Discharging: Once the mixing process is complete, the uniformly blended materials are discharged through the valve at the bottom of the pan. The mixed materials are then ready for the next stage of production, typically involving a molding machine to form briquettes or other shapes.
Raw Materials
The wheel grinder mixer is designed to handle a variety of raw materials, particularly those that are powdery or granular in nature.




Charcoal Powder: Ground charcoal from wood or other biomass.
Binder: Materials like starch, clay, or molasses to help bind the charcoal powder together.
Water: Used to mix with the powder and binder to form a cohesive mixture.
Clay: Different types of clay such as kaolin, ball clay, and fire clay.
Cement: Powdered cement used in mortar and concrete.
Sand: Fine aggregate used in combination with cement and water.
Lime: Used in some types of mortar.
Nutrient Powder: Such as urea, phosphate, potassium chloride, and other fertilizers.
Ore Powder: Ground mineral ores such as iron ore, copper ore, or gold ore.
Chemical Powder: Various chemicals in powder form, such as sodium carbonate, calcium carbonate, and others.
Finished Product
After the materials are mixed by the wheel grinder mixer, they typically form a homogeneous mixture with a consistent texture and appearance.
Homogeneous Mixture: The charcoal powder, binder, and water are thoroughly mixed to form a uniform paste-like consistency.
Dark Color: Due to the presence of charcoal powder, the mixture typically has a dark gray to black color.
Features of Wheel Grinder Mixer
- 1. Uniform Mixing: The combination of rolling, stirring, grinding actions ensures that all components are thoroughly mixed. This results in a homogeneous mixture, essential for producing high-quality charcoal briquettes.
- 2. High Efficiency: Capable of handling large quantities of materials in a single batch. The efficient mixing process reduces processing time, increasing overall productivity.
- 3. Enhanced Compaction: The heavy rollers apply consistent pressure, ensuring that the materials are compacted uniformly. This leads to denser final products, improving the quality of the charcoal briquettes.
- 4. Durable: Constructed from high-quality robust materials, the mixer is designed for long-term use in demanding environments.
- 5. Easy to Operate: Straightforward controls for loading, mixing, and discharging materials.
- 6. Versatile: Besides charcoal production, the wheel grinder mixer can be used in other industries, such as ceramics, fertilizers, and mineral processing, where thorough mixing of powdery materials is required.
Application of Wheel Grinder Mixer
Charcoal Briquette Production: The wheel grinder mixer is widely used in the production of charcoal briquettes. It mixes charcoal powder with binders (like starch or clay) and water to form a homogeneous mixture, which is then processed in molding machines to produce briquettes. Ensures consistent quality of the briquettes by providing a uniform mixture, which is essential for achieving the desired density and burn characteristics.
Ceramics and Pottery: Used in the ceramics industry to mix clay with additives and water to achieve a consistent and workable material.
Construction Materials: Can be used for mixing concrete, cement, sand, lime, and water in small-scale construction projects.
Fertilizer Production: Utilized in the production of compound fertilizers, where different powdered nutrients and binders are mixed to create a homogeneous product.
Mineral Processing: The wheel grinder mixer is used to mix powdered ores with water and chemicals to prepare them for further processing.
Chemical Industry: Used for mixing powdered chemicals with binders and other additives to produce a variety of chemical products.
Maintenance of Wheel Grinder Mixer
To ensure the longevity and efficient operation of the wheel grinder mixer, regular maintenance is essential.
Inspection of Rollers and Pan: Regularly check for wear and tear and replace any worn-out parts.
Lubrication: Ensure that all moving parts, especially the rollers and drive mechanism, are well-lubricated to reduce friction and wear.
Cleaning: After each use, thoroughly clean the mixing pan and discharge valve to prevent the buildup of materials, which can affect performance.
Tightening Bolts and Belts: Periodically check and tighten any loose bolts and belts to maintain optimal operation.
