ZYLAB Rotary Sample Divider | Automatic Powder & Granule Sample Splitting Equipment
Introduction:
The rotary sample divider is an instrument designed to evenly divide a bulk sample into several smaller, representative portions. Each portion maintains the same physical and chemical properties as the entire sample, accurately reflecting its characteristics. The sample is directed into receiving containers through an eccentrically set sampling funnel. The rotary sample divider is currently one of the most precise sample dividing instruments available.
The rotary sample divider is equipped with a synchronized automatic feeding system, ensuring precise and consistent material delivery. This configuration enables a fully automated sampling process, significantly improving efficiency and reliability.

Working Principle:
The automatic feeder provides uniform and continuous feeding of both granular and fine powder samples, making it highly versatile for different applications. Samples pass through the feeding hopper onto a vibrating chute. By adjusting the vibration frequency, the feeding speed can be precisely controlled, ensuring stable and consistent sample delivery to the next stage of processing.
The sample bottles feature a plug-in design, allowing for quick installation and removal, while the compact construction requires no maintenance. The instrument is equipped with an RS232 data transmission interface, facilitating convenient software upgrades and system maintenance. Furthermore, a strong magnetic anti-interference system enhances stability and reliability during operation.
Applications:
The Sample Divider is used in various fields such as agriculture, chemistry, synthetic materials, pharmaceuticals, geology, metallurgy, engineering, electronics, building materials, environment, resource recycling, glass, ceramics, biology, and food. It is ideal for sample division and sample reduction tasks.
