MULTIDOS weighfeeders are complete weighing systems with extensive variants to adapt to different feed rates, bulk solids properties, and application-specific marginal conditions.
- feed rates: up to approx. 1000 t/h
- main fields of use:cement, steel, and minerals industries
- for granular bulk solids (clinker, gypsum, lump coal)
- for powdery and mealy bulk solids (raw meal, fly ash, filter dust)
- for difficult to handle/sticky bulk solids (clay, marl, gypsum from flue gas desulfurization)

Milltronics weighfeeders from Siemens can improve the accuracy of processing, blend consistencies, accountability, and record keeping. All weighfeeders come standard with a belt weigh bridge and speed sensor. An integrator is required to complete the system.
The weighfeeder is used to deliver an accurate mass flow rate of material. In the majority of applications, material is profiled by an adjustable mechanical shear gate, which fixes the correct material bed depth for a given particle size.
The feed rate is then maintained and adjusted by varying the speed of the belt. However, in some cases the belt speed is constant with rate control (if any) done by a pre-feeding device.
The system consists of three components: weight and speed sensing, integration and control, and the mechanical conveying system.
Using the belt load and the belt speed signals, small incremental totals of weight per time are measured by the integrator and then the flow rate is calculated. The measured flowrate is compared against the desired flowrate and the on-board PID controller makes necessary corrections to the belt speed.

These machines are suitable to dose in continuous powder, granular and fibre materials. They are particularly suitable for fluid materials and can reach feed rates up to several tons per hour.
As belt feeders can be installed directly under a silo or pre-storage hoppers, while as weighing belts can be re-filled in continuous from other extractor machines such as screws, stellar valves other belts. These machines are equipped with a weighing bridge with loading cells and they can be also equipped with different control devices suitable to satisfy the most various dosing and weighing needs, both in continuous and batch.

Sandvik RBF-series belt feeders can be assembled in various ways to match the application exactly due to their modular structure . Available with ten belt widths from 650-2400 mm and in lengths from 1.5-15 m, they are designed for applications with capacities up to 2600 m3/h. The RBF-series belt feeders suit for materials that have at least moderate internal cutting properties such as coal, lime, Fe-pellets, metal concentrates and different rocky materials.
Sandvik RBF-series belt feeders have wide and adjustable capacity range while they are reliable, silent, steady and have low raise of dust. Due to the adjustable and controllable output the RBF-series belt feeder can be used in applications where accurate feeding is needed.
Sandvik RBF-series belt feeders are easy to assemble, install and operate. With a wide range of standard modules and components they can be tailored exactly to meet the application requirements. At the same time, they are versatile, easy to adapt and easy to service.

Modular in design, ASGCO Weigh Belt Scale performs in a wide variety of conveyor styles and structures in English or metric. Versatile ASGCO Weigh Belt Scale installs in series to create a 2 or 3 idler weigh bridge - minimum of 2 load cells.
- Easy to Install - ASGCO Weigh Belt Scale which typically takes less than 2 hours for complete installation and start up!
- Virtually Maintenance Free - because its low profile minimizes build-up areas where dust and dirt accumulate.
- User Friendly Software Powers the ASGCO Totalizer - requiring input of only 5 field parameters before initial calibration.
- The Totalizer is Automated - because belt length and speed are automatically calculated and entered.
- Totalizer Provides a Wide Variety of Outputs - to drive printers, chart recorders, PLC devices and controllers.
- ASGCO Weigh Belt Scale is Simple - consisting of a speed sensor standard encoder - no expensive housings or assemblies
- A wide selection of Options are Available: wheel mount kit for speed sensor, cross tube kit for heavy duty / high belt loading applications, low capacity load cells for light duty applications and field wiring installation kits.

The scale operates while the conveyor is in motion and is intended for the weighing of individual boxes, cartons, cans or -unpackaged products such as large cuts of meat. It is ideally suited to checkweighing, straight weighing and weight accumulation operations.
Fully automatic - Dual photo electric cell arrangement allows maximum accuracy in weighing randomly sized products. Excellent for feeding meat production lines or for checkweighing boxes, cans, cartons etc. Detect weight problems in-line.
Self-contained - Freestanding, self-powered design operates independently of existing belt conveyor. Unaffected by idler friction or belt tension and requires no damping device. Installs easily in new or existing facilities.
Stainless or carbon steel construction - Provides a cost effective choice based on material handling requirements. Stainless steel scales are matched with a stainless steel indicator to meet NEMA 4X standards for washdown and corrosion resistance.
Belting - USDA approved acetal flush grid with 31% open area for easy maintenance. Special belting available.
Weigh Bar accuracy and reliability - Weigh-Tronix patented weighbar design cancels out side, end and torsional forces to provide a true downward load. Fully electronic design eliminates moving parts that may be affected by wear or misadjustments.

Ramsey Series 14 Belt Scale System
The Thermo Scientific Ramsey Series 14 Precision Belt Scale System is specifically designed for high accuracy or basis-of-payment applications requiring certification by government and regulatory agencies. It is extremely accurate to within 0.125% and is the most widely certified belt scale in the world. It lets you monitor production output and inventory, or regulate product loadout, while providing vital information for the effective management and efficient operation of your business.
Product Detail
The Thermo Scientific Ramsey Series 14 Precision Belt Scale System from Thermo Fisher Scientific is specifically designed for high-accuracy or basis-of-payment applications requiring certification by government and regulatory agencies.
The Thermo Scientific Ramsey Series 14 incorporates the Ramsey 10-14 low-deflection, full-floating unitized weighbridge and the Ramsey 61-12C Belt Speed Sensor. Both are well-proven on hundreds of precision belt weighing installations.
It also utilizes the Ramsey Micro-Tech 2301 or Ramsey Micro-Tech 3301 Electronic Integrator and the Ramsey 2301-D Load Cell Exciter/Digitizer, which are the products of 50 years of design and application experience with high-accuracy belt scales.
Applications
The Thermo Scientific Ramsey Series 14 Precision Belt Scale System represents the world standard of accuracy and performance for loadout, inventory monitoring and fee-holder type applications requiring certification.
Certification
As the most widely certified electronic belt scale in the world, the Thermo Scientific Ramsey Series 14 has received its Certificate of Conformance in the United States as issued under the National Type Evaluation Program (NTEP) of the National Conference on Weights and Measures. Outside of the US, it is certified by OIML and EEC Class I standards.
Performance Guarantee
On factory-approved installations, we guarantee that the Thermo Scientific Ramsey Series 14 Precision Belt Scale System will weigh and totalize to a value within ±0.125% of the test load at flow rates between 25% and 100% of the scale system's calibrated capacity when calibrated against an actual weighed material test. Furthermore, we warrant that the scale system will repeat to within 0.1% of consecutively run, simulated calibration tests.
