Pre-grinding
Optimization of raw materials for maximum efficiency
Pre-grinding plays a crucial role in the processing of raw materials. Its primary function is to prepare materials by reducing them to an initial, more manageable size. This initial dimensional reduction has a significant impact on the entire process, improving energy efficiency and optimizing the quality of particles to be further processed.
Once the materials are fed, our pre-grinding unit comes into action. Equipped with robust grinding devices tailored to the specific characteristics of the processed raw materials, the goal is to effectively reduce particle size while minimizing the generation of undesirable fines. This initial fragmentation stage greatly facilitates subsequent process steps by creating homogeneous particles tailored to the specific requirements of the final product.
Poittemill’s distinctive expertise is fully evident in the design of our pre-grinding units. We understand the importance of a customized approach to address the unique characteristics of each raw material. Our engineers implement advanced technologies to ensure precise and efficient fragmentation while minimizing energy consumption.
Furthermore, the design of our pre-grinding devices incorporates advanced control mechanisms that allow for adjusting particle size according to the precise specifications of the final product. This flexibility is essential to adapt to variations in raw materials and ensure consistency in the quality of the final product.
Fine and ultra-fine grinding
The Art of Transforming Materials into Superior Quality Particles
Fine and ultra-fine grinding represents a crucial stage in our process, where previously prepared materials reach the desired particle size. This delicate phase, at the core of our process engineering, aims to transform raw materials into fine and homogeneous particles that meet the precise specifications of the final product.
The process starts after pre-grinding, with materials now reduced to a manageable initial size. These particles enter our grinding units, equipped with advanced grinding technologies. These fine and ultra-fine grinding mechanisms are precisely designed to ensure optimal reduction of particle size without compromising quality.
The careful selection of grinding devices is a distinctive feature of our expertise at Poittemill.

Classification
Precision and Discernment at the Heart of the Process
The separation technique, a crucial step in our process, embodies the precision and discernment required to isolate different fractions of the processed materials. This phase plays a determining role in the final product’s quality by ensuring that only the desired particles progress through the subsequent stages.
The process begins after grinding, when the materials consist of different particle sizes. Separation units come into action to sort and classify particles based on their size, specific weight, or other physical characteristics.
Various separation techniques are implemented, such as vibrating screens, cyclones, or our high-classification separators, depending on the specific properties of the materials and the requirements of the final product. These devices act selectively, allowing each fraction to follow a determined path while eliminating undesirable particles.
The precision of this step is essential to ensure the homogeneous quality of the final product. Poittemill engineers optimize the configuration of separation devices based on the unique properties of the processed materials, minimizing losses and maximizing the overall process yield.
Cutting-edge technology is integrated into our separation units to ensure optimal performance. Advanced control systems dynamically adjust separation parameters based on variations in raw materials, ensuring adaptability to changing production conditions.
Aspiration and filtration
Air Purification and Quality Assurance
The crucial stage of aspiration and filtration in our transformation process is dedicated to air purification and ensuring the quality of the finished products. This phase ensures a safe working environment while eliminating undesirable particles that could compromise the quality of the final product.
Aspiration: The process begins with strategically positioned aspiration systems. These devices are designed to capture and suction fine particles and dust generated throughout the previous stages of the process. Aspiration is meticulously calibrated to maintain a clean working environment, promoting operational safety and the well-being of workers.
Filtration: The aspirated particles then pass through advanced filtration systems. These filters are specifically chosen for their ability to retain different sizes of particles, ensuring that only the desired fine and ultra-fine particles progress in the process. Filtration is a critical element for the quality of the final product, eliminating contaminants and ensuring strict purity standards.
We integrate high-efficiency filters, optimized for selective particle retention, while minimizing the loss of valuable material. Filtration systems are precisely sized based on air flow and particle characteristics, ensuring maximum performance.
In summary, aspiration and filtration at Poittemill are not just safety measures; it is a commitment to the quality of the final product. Each particle that progresses after this stage is the result of meticulous air purification, underscoring our dedication to quality, safety, and the overall excellence of our transformation process.
Stockage and handling
Strategic Storage for Continuous and Optimized Flow
Once the materials are processed, they are directed to specially designed storage silos. These silos function to temporarily receive raw materials awaiting further processing. The design of the silos is tailored to the specific properties of the materials, ensuring sufficient capacity while avoiding risks of contamination or deterioration.
Transport through the Silos: Silos are not just storage points; they are also integrated into a transport system that guides materials to different phases of the process. The strategic design of these silos facilitates a continuous and regulated flow, optimizing the transition of materials between different treatment stages.
At Poittemill, we consider not only the required storage capacity but also the ease of loading and unloading, minimizing downtime and maximizing operational efficiency.
