The DJRC Series Jaw Crusher & RSD integrates a jaw crusher and Rotating Sample Divider (RSD) in a single unit, enabling efficient one-step sample size reduction and division. With a robust structure, adjustable jaw settings and precise splitting control, the series is designed for standardized sample preparation in geological, mining, commercial testing and research laboratories.
By automating both the initial size reduction and subsequent proportional sub-sampling in one continuous operation, it eliminates manual handling errors, significantly reduces preparation time, and ensures that every subsample truly represents the bulk material, laying the foundation for highly reliable analytical results. As a hallmark of DECENT Group’s commitment to innovation and quality, this combined system is built for rigorous, continuous operation, guaranteeing unparalleled consistency and throughput.
DJRC70 and DJRC80A feature a dual movable jaw configuration. Both jaws move during crushing to improve crushing efficiency, deliver consistent particle size and achieve a high reduction ratio. Their reversible jaw plates can be rotated top-to-bottom to extend service life and reduce operating costs, making these models well suited to applications requiring high sample preparation accuracy.
DJRC80 and DJRC80B use a conventional jaw configuration with one fixed jaw and one movable jaw. They provide reliable crushing and splitting with simple operation and low operating costs, making them well suited to routine batch sample preparation and mine grade-control laboratories.
This RSD unit maintains a consistent rotation speed, proportionally dividing the sample into specified ratios (from 5% to 50%) between collection trays and receiving buckets, which is vital for obtaining representative subsamples. Both components are constructed from highly durable, wear-resistant materials, ensuring an extended service life and minimizing maintenance demands even under heavy use. The Jaw Crusher RSD optimizes your workflow, providing a streamlined, automated, and highly accurate sample preparation process.
