Learn more about our battery production pneumatic blender and five considerations that ensure a good system design.

safety in the battery manufacturing process

Pneumatic conveying is the ideal method for conveying hard-to-handle, hazardous powders because the system is completely enclosed utilizing sealed pipelines to move powders from the collection point(s) to the destination point(s).

The destination points are fitted with local bin vent filters to capture and mitigate dust, creating a dust-free environment. For certain processes and materials, vacuum systems can be utilized to improve plant cleanliness. With vacuum systems, leaks or pinholes will seep into the system vs. out into the plant. Additionally, pneumatic blending utilizes air to fluidize and blend dry powders, while keeping materials contained in a dust-tight bin.

Lastly, our equipment is designed with operator safety in mind. Routine equipment maintenance is made easy with bag-in-bag-out dust collection options. These designs allow the operator to be completely isolated while replacing the dust bags and filter elements, protecting them from hazardous materials.

component wear and metal contamination

Reducing component wear, in turn, decreases the likelihood of metal contamination, based on two general principles – low material velocities and low shear. Lowering material velocities with dense phase pneumatic conveying – Pneumatic conveying is typically classified into two methods: dense phase and dilute phase. In simple terms, dense phase pneumatic conveying results in lower material velocities, while dilute phase pneumatic conveying results in higher material velocities. Picture a gentle extrusion process vs. sandblasting.

When handling abrasive materials, dense phase pneumatic conveying is the best method to reduce component wear. Nol-Tec’s dense phase conveying systems utilize strategically placed Air Assist™ technology throughout the convey lines to ensure the slowest product velocities. The addition of air throughout the convey lines allows the system to run at the slowest material velocities while maintaining system throughput. The additional energy ensures the system can run as slow as possible without plugging.

low shear pneumatic blending

Many complex steps are involved in the battery manufacturing process that require the homogenous blending of dry powders. Several of the powders that require blending are abrasive and require special care to reduce metal contamination. Pneumatic blending generates a homogenous blend using air as the motive force. Using air to produce the blending action creates a low shear and low abrasion environment, reducing the risk of metal contamination. Additionally, blend cones can be ceramic coated further protecting the system from wear and the final product from metal contamination.

Conditioned Air or Gas for Conveying and Blanketing Powders

Pneumatic conveying and blending are enclosed processes that allow for further conditioning of the motive gas used to move or blend the materials. These processes can easily be designed to use clean dry air, other gases, or carbon-free air – eliminating moisture or contamination concerns.
