Rotary Sample Divider 8 x 25 Liters

DESCRIPTION

The Rotary Sample Divider 8 x 25 Liters is designed for accurate, efficient, and repeatable sample division, producing highly representative sub-samples for laboratory and pilot-scale applications. With an accuracy of ±1% by weight, it helps maintain the characteristics of the original sample, reducing sampling errors and improving the reliability of analytical results.

This high-capacity rotary sample divider is equipped with eight stainless steel, triangular prism-shaped dividing containers, each with a 25-liter capacity, making it suitable for processing large sample quantities with ease. Its homogeneous sample distribution principle ensures consistent and unbiased division, which is essential for dependable laboratory analysis and sample preparation processes. The 120-liter  feeding hopper provides smooth and controlled material feeding into the dividing system.

Both the rotation speed of the dividing containers and the feeding speed can be adjusted, allowing the operator to optimize the machine according to different sample types, particle sizes, and process requirements. Mounted on a mobile chassis with four wheels, the machine can be relocated easily when needed. The front-opening safety enclosure provides both operator protection and practical access during operation, cleaning, and routine handling.

Dividing Containers: Includes 8 stainless steel, radial (triangular prism) containers, each with a 25-liter capacity.
Feeding Hopper: Equipped with a 120-liter stainless steel feeding hopper.
Rotation Speed: The rotation speed of the containers can be smoothly adjusted from 0 to 60 rpm via an electronic speed control.
Sample Size: Capable of handling samples with particle sizes from 0 to 150 mm.
Mobile Design: Mounted on a four-wheeled mobile chassis with a front-opening safety cage for secure operation.

The lid safety switch prevents operation when the lid is open, ensuring maximum operator safety by avoiding potential accidents. The motor will not engage, and the operation cannot start until the lid is securely closed.

An emergency stop button is also included, providing immediate shutdown if needed. These features are essential for both operator safety and the safe operation of the machine.

The Rotary Sample Divider 8×25 Liters comes with 8 stainless steel, 25-liter containers as standard. As seen in the video, a fixed container version with bottom discharge is also available for more efficient sample handling.

APPLICATION AREAS

Our Rotary Sample Dividers are suitable for sampling a wide range of materials. Some uses include:

Mineral ores (copper, iron, gold, chrome ores), coffee, peanuts, hazelnuts, coal, concrete, ceramics, quartz, corundum, granite, slag and cement clinker, some industrial wastes, etc.

WORKING PRINCIPLE

Rotary Sample Dividers are designed to achieve high-precision sample division during sample preparation processes. These devices ensure that each sub-sample accurately represents the main sample by dividing the material homogeneously.

The operating principle of the rotary sample divider begins with transferring the sample to the device’s hopper. The sample is evenly distributed by a rotating distributor and directed into pre-determined compartments. As the sample hopper rotates, the material is divided in fixed ratios and directed into the sample containers. This rotary motion enables uniform distribution and precise division of the sample.

Since the sampling process is carried out automatically, errors due to human factors are minimized. Although sample collection may seem straightforward, it is the most critical step for accurate analysis results. The automated system ensures a reliable, repeatable, and precise sampling process.
