GKM Siebtechnik
Screeners for fractionating and control screening
Specialists in precision screening
GKM Siebtechnik is a German manufacturer specializing in screening technology for the industrial handling and processing of powders, granules, and other bulk materials. With more than 25 years of experience, the company develops solutions for fine, control, security, and classification screening.
GKM screening machines are used to classify products by particle size, remove unwanted particles, and ensure consistent product quality.
The product portfolio ranges from laboratory equipment to high-capacity industrial screening machines and solutions for continuous production processes.
Tumbler screening for precise separation
A core area of GKM’s product portfolio is tumbler screening, where a three-dimensional motion is applied for gentle and efficient product separation. This technology is particularly suitable for fine powders and products with stringent separation accuracy requirements.
Depending on the machine type and application, multiple screen decks can be deployed to separate the product into different fractions in a single process. GKM offers machines capable of classifying up to seven fractions simultaneously.
Control and security screening
GKM also provides compact vibratory screeners for control and security screening. Here, the primary objective is not multi-fraction separation, but ensuring that off-spec particles, agglomerates, or foreign bodies are removed before the product moves to the next process stage.
This type of screening can be integrated prior to packaging, dosing, or further downstream processing. GKM’s high-capacity screening machines are engineered for control and security screening of both dry and wet products, featuring solutions targeted specifically at food and pharmaceutical processing.
Flexible solutions for diverse products
Different powders and granules place varying demands on the screening process. For instance, fine or cohesive materials may tend to blind the screen mesh, whereas other products require high throughput or exceptionally gentle handling.
GKM therefore offers various de-blinding systems to keep the screen mesh clear, including solutions utilizing cleaning balls, plastic rings, and ultrasonics. In addition, the machines can be configured with varying numbers of screen decks and tailored to the specific separation task.
Focus on hygiene and cleanability
In food and pharmaceutical manufacturing, sanitary design is of paramount importance. GKM supplies machines with product-contact parts in stainless steel and designs where screen inserts and other components can be readily dismantled for cleaning. Select solutions also utilize food-contact-approved materials and can be delivered in configurations meeting the most stringent hygiene requirements.
The ability to perform rapid screen insert changeovers is equally critical when production switches between different products or particle sizes. This minimizes downtime and enhances the versatility of a single screening machine across multiple process tasks.
From laboratory to production
GKM’s product range also includes laboratory screeners for analyzing dry powders and granules, as well as wet screening. This laboratory equipment is used to determine particle size distribution, supporting both product development and quality control.
This allows for an integrated screening approach across multiple process stages—from initial product analysis and testing to industrial separation and continuous in-line quality assurance.
Specialized screening technology
GKM Siebtechnik serves as a dedicated manufacturer of screening equipment for industries processing powders and bulk materials. The combination of tumbler screening, vibratory screening, control and security screening, and laboratory equipment allows technology selection to be tailored precisely to the process and product characteristics.
Selecting the right screening solution involves more than just mesh size. Product flow properties, target capacity, separation accuracy, hygiene standards, and screen blinding tendencies must all be evaluated holistically. With the optimal combination of screening machine, screen mesh, and de-blinding system, GKM solutions deliver a stable and reproducible screening process.
