Achieving consistent particle size control in ceramic powder production
Ceramic powders are widely used across manufacturing applications, where precise particle size control and consistent material quality are essential. Due to their abrasive nature and tendency to clump, sieving ceramic powder presents processing challenges, including inconsistent separation, reduced screening efficiency, and increased equipment wear. Clumps, also known as agglomerates, reduce product consistency, create uneven particle size distribution, and can blind the mesh, slowing overall productivity. This demonstration video shows how a compact vibratory check screener, fitted with our Russell Vibrasonic® Deblinding System, removes oversize and agglomerates from ceramic powder while keeping the mesh screen clear.
Why is it critical to eliminate lumps from ceramic powder?
Ceramic powder can clump at multiple stages of processing, including storage, milling, and handling. Factors such as moisture absorption during storage, compaction during handling, electrostatic charge between the ceramic particles, and heat generated during milling all cause fine particles to bond together. If agglomerates are not removed before downstream processing, they disrupt the uniformity of the powder bed. It compromises the integrity of the formed part, increases the risk of product rejection, and results in costly reprocessing.
For manufacturers supplying high-specification ceramic components, a single batch of poorly distributed powder can result in significant material loss and production downtime. Therefore, eliminating agglomerates at the screening stage is essential to ensure every batch meets the required quality specification.
Why is particle size control necessary in ceramic powder processing?
Across applications such as technical ceramics, electronic components, refractories, and coatings, particle size control is necessary as it determines the quality and performance of the final ceramic product. Variations in particle size affect product density, how the powders behave when heated, and the final surface finish.
Using our high-performance round separator for screening ceramic powder
In this demonstration video, our Finex®22 fitted with our Russell Vibrasonic® Deblinding System is used to screen white ceramic powder. It effectively removes oversized particles and breaks hard agglomerates, producing a fine, consistent powder while eliminating mesh blinding, all in one operation.
With a 22-inch diameter and a single-deck configuration, our Finex®22 is a cost-effective solution for check screening ceramic powder for further processing and packaging. Ceramic powder is inherently fine and prone to mesh blinding, so the machine is fitted with our ultrasonic sieving equipment, which applies high-frequency directly to the mesh surface. This breaks down hard agglomerates and keeps fine particles moving through the mesh rather than blocking the apertures, maintaining consistent flow rate and screening accuracy over long production runs. Its smaller footprint makes it well suited to facilities with limited floor space, delivering efficient performance in ceramic powder screening.
How does our Finex®22 deliver reliable ceramic powder separation?
Our Finex®22 is a compact vibratory sieve designed to deliver reliable, repeatable separation for a wide range of powder processing applications. Its robust construction and space-saving design make it particularly suitable for check screening ceramic powder, where accuracy and ease of cleaning are critical. When fitted with our Russell Vibrasonic® Deblinding System, it is especially effective on fine, sticky, or hard-agglomerating powders that would otherwise blind the mesh. Our Finex®22 is widely used across ceramics, chemicals, and food ingredient processing. Its open frame design with crevice-free welds allows for easy cleaning and rapid access to all contact parts, minimizing downtime between production runs.

Frequently asked questions:
Agglomerates are formed in our ceramic powder during milling and storage. How does the Finex®22 remove them before the powder reaches the shaping or heating stage?
Our Finex®22 screens ceramic powder through a single micron mesh while our ultrasonic sieving equipment breaks down hard agglomerates. This removes oversized particles and delivers a uniform fine powder before downstream processing.
How does particle size distribution in ceramic powder affect how well the powder absorbs heat and becomes a strong final product?
When ceramic powder has uneven particle sizes, it does not pack together evenly, so heat cannot move through it properly. Our Finex®22 removes oversized particles and lumps to create a more even powder, helping it heat consistently and form a stronger final product.
When is a single deck check screener the best choice, and when is a multi-deck separator more beneficial for sieving ceramic powder?
Our Finex®22 is a compact, cost-effective single-deck check screener designed to remove oversized particles efficiently and agglomerates from wet and dry applications. It delivers fast and reliable screening performance in a small footprint and is an ideal solution for facilities that require effective quality control without complexity and space requirements. For applications requiring multiple particle-size separations in a single pass, a multi-deck separator such as our Finex Ultima™ and Finex Separator™ offers greater classification flexibility and efficiency.
Our ceramic powder forms hard agglomerates that blind the mesh and slow down screening performance. How does the Finex®22 handle this?
Our Finex®22, when fitted with the Russell Vibrasonic® Deblinding System, applies high-frequency energy to the mesh surface. This breaks down hard agglomerates and prevents fine ceramic particles from clogging the mesh apertures, maintaining consistent flow and productivity even with difficult and sticky powders.
At what stages of ceramic powder processing should agglomerate removal and deblinding be applied?
Our Finex®22 integrated with our Russell Vibrasonic® deblinding system can be integrated at every stage of the process, from raw material intake, post-milling, post-spray drying, pre-pressing, and reprocessing of off-specification material. Controlling particle size and mesh condition at each transfer point ensures uniform distribution and maintains consistent productivity throughout the entire production process.
Beyond ceramics, what other industries and powder applications is the Finex®22 with vibrasonic deblinding equipment used for?
Our Finex®22 integrated with the Russell Vibrasonic® Deblinding System is widely used across industries such as chemicals, food ingredients, pharmaceuticals, battery materials, and metal powders. It is ideal for screening fine, sticky, and agglomeration-prone powders, helping to reduce mesh blinding, maintain productivity and improve product quality.
