Precision Sampling Mechanism
The Cross Belt Sampler features a double sweep cleaning system that works in conjunction with the flexible idlers that shape the belt into an arc to guarantee a clean sweep of fines, and a representative sample increment. The servo-controlled, low-backlash, closed-loop feedback drive system provides precise speed control of the sample cutter, ensuring mechanically correct sample extraction. The cutter is engineered to make full contact with the conveyor belt across the width of the cutter and the belt, facilitating a complete and clean cut of the material, including fines on the belt surface.
Robust and Safe Design
Constructed for durability, the sampler includes belt tracking limit switch interlocks and a lead-in flap that assists the sample cutter onto the conveyor upon initial contact, minimizing potential belt damage. Skirts on the feed and discharge ends further enhance material containment. Safety is prioritized with features such as emergency stop buttons and a warning siren that alerts operators 10 seconds before sampling commences.
Versatile Operating Modes
The sampler offers four distinct modes of operation to accommodate various operational needs:
- Manual Mode: Operator-initiated sampling.
- Auto Timed Mode: Sampling at predetermined intervals.
- Remote Mode: Operation from a centralized control system.
- Inspection/Maintenance Mode: Positions the sample cutter opposite the inspection windows for easy inspection and routine maintenance.
