Weigh feeders are conveyor and weighing systems in one, whereby the conveyor belt is designed specifically for the requirements of precise weighing and equipped with a separate weighing section. The scales are particularly suitable for measuring and dosing tasks, weighing light bulk materials or low to medium feed rates. The requirements for the application and product properties of the material to be weighed are determined by the design of the weigh feeder. The VBF/EE weigh feeder is an extremely robust belt scale, which are available in very short lengths from 1,200 mm due to their construction. Use: - Process control - Regulating tasks - Light bulk materials - Truck and wagon loading - Also legal-for-trade Benefits: 1. Highly variable - Belt lengths and belt widths can be individually adapted to application requirements. Belt conveyor optionally available as a flat or troughed belt, with a corrugated edge, in rubber, PVC or FDA-compliant design. In open or closed design. 2. Very robust - The scale has always excelled in many applications, even in harsh industrial use, in dusty environments and in continuous operation. 3. Good measuring accuracy - In particular in conjunction with ModWeigh FBW control units (for continuous quantity recording) or ModWeigh DBW (for regulated weighing and dosing tasks). 4. Durability 5. Low maintenance effort

Some conveying tasks bring up the question: How much material did the system convey and feed? A batch weighing and loading of bulk material is achievable through the Volkmann CONWEIGH system. Our CONWEIGH Vacuum Conveying and Weighing/Dosing systems measure both the incoming and outgoing material flow. You can set these systems to convey a certain amount of product or just control the feed rate over time, the CONWEIGH does the rest. It gives you a vacuum conveyor with fine dosing function that gives a perfance of up to 99.7% / 99.9% precision (depending on material condition and installation). Volkmann CONWEIGH Vacuum Conveying systems with weighing and dosing function are designed to incorporate our VS and PPC conveyors, therefore able to provie a wide range of options and customisation for an individual application. They work gravimetrically with the vacuum conveyor mounted on a special frame designed to completely isolate the system from external forces and loads. The filling weight is constantly measured throughout the suction cycle. The amount of material to be conveyed is specified (through a touch screen input). If different materials must be transferred from a number of pick-up locations, the control can operate the necessary diverter valves to activate the proper transportation line automatically. CONWEIGH systems can be programmed to deliver recipes into the process. The combined transfer/weighing CONWEIGH system is used for dosing weights of 2 kg and above. Typical for vacuum conveying, the transported material is released discontinuously in cycles. The maximum dosing capacity is defined by the transportation capacity of the vacuum conveyor, for CONWEIGH this is up to 4 t/h. The accuracy of the system is 99-99.7% of the indicated value (configured to customer demands).

Weighing bellows are for the flexible connection of mixers, feeders or vessels on weighing cells to supply lines, drain pipes or other forms of air transport or powder transport. These conical weighing bellows have an asymmetrical hygienic design.

The stainless steel weighing module enables the simple and problem-free integration of the laser-welded K30N load cells. A particular advantage of this module is the central load introduction, which takes place via two hardened ball sockets and a ball. Even with parasitic forces such as wind loads on silos or lateral forces on containers, the exact load introduction is guaranteed - for always precise measurement results.

The VC 3500 and LCM 460 are heavy-duty modules for weighing silos, hoppers, tanks and mixers. The special construction of the modules permits installation directly between the foundation or substructure and hopper support. The module ensures the optimal force transmission and a very high lift-off and lateral load safety - normally without additional transverse link and captivation mechanics. For nominal loads from 2 up to 200 t. Use: - Fill level and inventory control - For mixer and hopper with agitator - For bunker, also with discharge bottom - Particularly for installations in outdoor areas - For precise silo weighing Benefits: 1. Measuring accuracy - Both modules are equipped with high-precision double shear beam load cells made of stainless steel. The LCM 460 even has an OIML R60 approval C3 for nominal loads up to 20 t. The construction of the module provides optimum force transmission into the load cell, thus ensuring reliable and exact weighing results. 2. Safety - The special construction of the modules protects the load cell from high lift-off and transverse loads, thus ensuring the installation of the weighing module directly between foundation and tank support. No additional transverse and captivation mechanics is required. Slight tilting can also be compensated. 3. Protection - Locking screws in the upper section of the module protect the load cell from such shock loads as may occur upon installation of the silo. An additional ground strape serves as overvoltage protection. 4. Easy replacement of load cell - The load cell is installed in the module in such a way that the load cell can be replaced also without removing the module. MTS offers numerous load cells and modules for silo and hopper weighing. Load cells and modules are selected according to the design, size and construction of the containers, the installation and environmental conditions and the required accuracy.

Weighing screw conveyor with automatic calibration. Weighing screw conveyor perform a dual function – they transport the bulk material from A to B and measure the throughput (t / h) and the absolute quantity delivered (t) simultaneously. Especially for fine and dusty products, such as white lime, hydrated lime, cement and starch a weighing screw conveyor provides the advantage of dust-free conveying. Due to the dual function (conveying and weighing) this results in an economical solution compared to conventional weight feeders and solids flow - measuring instruments. Requirements for the use of weighing screw conveyors: 1. To ensure optimum transport of the bulk material in conjunction with a precise weighing, the inlet- and the outlet connection must be fully decoupled. The input feed should be controlled via a rotary valve or a second screw conveyor. 2. The screw should only be filled to maximum 40% of the conveying capacity -otherwise a part of the conveyed product is thrown over and double-weighted. 3. Evt. Caking in the conveyor tube or on the screw flights should be zeroed periodically. Especially the third point can often not be realized in practice. Screw conveyor often dose additives (eg. hydrated lime in the flue gas desulfurization) and are in operation 24 hours arround the clock. In order to still be able to use the serious advantages of weighing screw conveyor, Hense Wägetechnik has developed a concept for automatic "self-calibration" in continuous operation. Functionality: The weighing screw is feed via a small hopper with a rotary valve in the discharge. The hopper is mounted on 4 precise "Clevermount" - weighing modules. The static hopper weighing system and the “weighted screw conveyor are connected to the same evaluation electronic. The “self calibration cycle” can be started periodically (over a programmable time) or externally from the PLS system. In the first step the hopper is filled to an adjustable weight. This value can be preselected in the evaluation electronic. The weighing electronics transmits a signal "start calibration cycle" to the parent PLS system. The filling of the hopper is stopped during the calibration. After a short settling time, the electronics stores the container weight (kg) and the state of the totalizer (kg). The electronic system now “waits” until the weight of the product in the hopper is reduced by an adjustable value (eg. 100 kg). Now the electronics compares the reference quantity (eg. 100 kg) withdrawn from the hopper to the counter of the weighing screw - on exceeding a defined fault tolerance, the system performs an automatic correction calibration. Furthermore, all data is logged in a log table and optionally set a tolerance alarm.
