DYNASCALE LOADBLOCK: Precision weighing for industrial applications
The Dynascale Loadblock belt weighing system ensures precise measurement of feed to crushers, mills, sieves, and other processes, achieving accuracies as low as +- 1-2% even in the most demanding conditions.
Enhanced design and versatile solutions
Our Loadblock solution, available in both single and double configurations, caters to belt widths up to 650 mm and up to 2000 mm respectively. Compared to the Thermo Ramsey IDEA Loadblock, our design boasts enhancements like all-steel construction for increased durability and reliability.
The compact and user-friendly design of the Dynascale Loadblock belt weighing system ensures easy handling and allows for a swift installation process, minimizing downtime and maximizing efficiency. Our Loadblock solution enables you to effectively monitor and control your production processes, providing valuable insights for optimizing efficiency and operations.
Engineered for process belt weighing in complex industrial environments, the Dynascale Loadblock belt weigher offers precise control over material supply, enhancing overall operational efficiency. Backed by the proven reliability of the Loadblock weighing frame, featuring 1 or 2 Loadblocks, in conjunction with the 526 speed sensor and the advanced WI301 weighing electronics, our Loadblock belt weigher delivers unparalleled performance and versatility.
Features and installation
The Dynascale belt scale model Loadblock is very easy to handle and installed by simply 2 bolts, delivered if needed with installation brackets, indoors or outdoors, on stationary or mobile belts. Its robust construction makes it suitable for the most difficult applications on a wide variety of applications.
The weighing frame
Its very compact design and robust construction keeps the Loadblock weighing frame fully in line with the conveyor frame. This one-piece or two-piece weighing frame is fully assembled at the factory and is quick and easy to install and integrate into the conveyor belt. The weighing frame is designed to provide additional support and reinforcement to the belt structure, thus minimising deviations. The Loadblock weighing frame is due to its specific design insensitive to vibration, moisture and product accumulation, unlike many other systems.
The belt speed sensor
The WIS526 digital speed transducer is the most reliable and accurate speed transducer ever developed for use with belt weighers. By directly connecting the transducer to the belt reversing roller or a return roller, you are guaranteed an accurate belt run reading. No wheels running over the belt, preventing problems caused by product accumulation or belt slip.
The Integrator
The WI301 integrator is a weight integrator for dynamic weighing systems. By integrating the mV signal from the load cells in the weighing frame and the pulse signal from the speed sensor, the WI301 integrator generates a readout for the product flow in e.g. tonnes/hour. It is also possible to read out the belt load (kg/m), belt speed (m/s) and the daily counter or total counter (kg or Ton). The integrator can also be equipped with various optional boards for e.g. communication purposes. The integrator can be used for both approved and non-approved applications.
Accuracy guarantee
On installations approved by us, we guarantee that the Loadblock belt weighing system weighs and counts within a value of +- 1% of the test value. Calibration should be done via a known test weight, calibration chain or our standard electronic calibration.
