With the MDW600, Piovan launches in the market its new range of gravimetric blenders. The new model has a nominal capacity of 600kg/h and can dose up to 8 different components.
The MDW600 is suitable for application in the fields of injection, extrusion and blow-moulding. It can be installed on the feed-throat of the injection moulding machine or extruder in single applications, or frame-mounted in centralised solutions.
The distinctive characteristic of the machine is represented by its high performance levels, achieved using specially designed components, so to fulfil the most stringent requirements. The new mixer with round bottom section, equipped with innovative mixing paddles guarantees homogeneous mixing, uniform blend descent and absence of stagnation. It is mounted on a load cell so to ensure constancy of operation and high accuracy of the blend.

DJ-9100 DispenseJet® Valve
HIGH-SPEED JET DISPENSING FOR LIQUID CRYSTAL FLUIDS
Dispense Liquid Crystal (LC) fluids quickly and accurately with the DJ-9100 jet. Fast, simple and more accurate, the DJ-9100 jet is based on Asymtek%u2019s standard DJ-9000 design. Jetting offers advantages over other LC dispensing methods and delivers better quality, increased flexibility and a low cost of ownership.
Speed: High flow rate %u2013 20 mg or more per second with a high shot rate up to 200 dots per second
Fluid Handling: Bottled LC material is fed directly rather than first transferred to a syringe, eliminating potential contamination and minimizing fluid waste
Cleaning: Quick and easy to clean in ten minutes or less
Quality: High wet-dispense accuracy; multiple dots jetted precisely where needed for One Drop Fill (ODF) of liquid crystal material
Avoids common hidden expenses: Easier and cheaper to operate
Other advantages include:
Jet small dots that promote wetting and allows for complex patterns impossible with other valves
Weighs material automatically, the dispenser adjusts automatically
Minimal wetted parts
Automatic tip cleaning and purge
Calibrated Process Jetting (CPJ%u2122 ) ensures volumetric repeatability during long production runs to improve process capability (Cpk). Dispense patterns are programmed with a specified weight. CPJ periodically samples the dispense weight per dot and computes the number of dots for each pattern. With this data, CPJ optimizes line speed based on the maximum specified shot interval.
Features
Up to 7 times faster than other valves
Eliminates setup complexities associated with multiple pump configurations
Designed for LC fluids
Fewer disposable parts
Avoids contamination of LC fluids while feeding to the jet

Complete mobile systems can be trailer or truck mounted. This is a general purpose type prover presently being used in the gas and petroleum industries. It could be adapted or modified for use in other industries as well. A range of sizes, up to 1500 gallons, can be produced.
An example of a trailer mounted prover is the 100 Gallon Volumetric Liquified Petroleum Gas Prover. This prover is in use by a State Bureau for the purpose of accurately measuring and checking flow meters and gauges. It is mounted on a trailer for maximum mobility and convenience for transporting the unit to inside or outside mounted meters. It can be used to check meters measuring LP (liquid petroleum gas) being loaded into the truck and or those meters measuring the gas as it is dispensed from the vehicle.
Any standard, or custom measures, or provers can be trailer or truck mounted to your specifications and for all industries whether it's for in-yard or over-the-road purposes.
Custom trailers meet all I.C.C. regulations. They can be equipped with brakes and can be leveled by jack screws or hydraulic jacks. Dual axles are available where required.
Benefits of the CMS Prover Systems are directed towards manpower and human resource savings which provide increased productivity, safety, visibility and ease of operation. Added results, improved customer relations. |

No powder, no granule and no fibre will show exactly the same behaviour.
The Gericke product range of feeders responds to the diverse characteristics of bulk materials and meets the requirements of the operation circumstances.
The offer include volumtric and b>gravimetric loss-in-weight feeders, batch feeders and vibration feeders.
The controller EasydosTM as "state of the art“ control of loss-in-weight feeders communicates via bus system. Due to its simple operation handling it fits for controlling of continuous mixing processes as well as for feeding of extruders.

In gravimetric feeding, dry bulk material or liquid is fed into a process at a constant weight per unit of time since weight is a variable that can be captured by a weighing module. Consistent control and complete monitoring are possible. In principle, gravimetric feeding combines monitoring of the feeding process with a feedback loop that enables accurate material control.
Typical application:
Precise feeding and blending of materials is a critical part of the process when manufacturing reinforced thermoplastics. Typical applications require the blending of several granular materials with one or two powder materials within a compact area at the throat of an extruder. Maintaining a steady and precise level of blended material above the throat of the extruder is also a requirement. |
|
Compact line of loss-in-weigh feeders for materials with varying bulk density: The digital load cell integrated is protected against corrosion by stainless steel housing and is equipped with vertical overload stops.
Two different application programs are proposed for batch or continuous dosing.
To reach a better dosing accuracy, the feeder is design in such a way that only ingredient hopper and extractors are weighed (It is possible to select a load cell with smaller range of measure and consequently smaller interval).
The feeder is controlled with a multitasking operating system combining the functions of an operator interface, weighing controller, PLC and interfaces.
Design of these feeders is made in agreement with drug and food industries requests for cleaning.

The essential tool for dosing in safety!
The anti-bridging doser is weighed and assisted by an electronic regulation system that provides a dosing accuracy between 0.25 and 0.5% thanks to the loss weight control.
It works either continuously or by load, depending on the process. The regulation system, at the leading edge of the computer technology and electronics, enables the user to control one or several dosers. |

Loss in weight feeders are used for the gravimetric dosage of bulk solids (powders, pellets, flakes,..) or liquids, with flow rate range between 1 and 30.000 kg/h allowing to reach high accuracy.
These feeders are applied for continuous blending or for feeding extruders or other process machinery.
Dosing equipment mainly consist of:
- Buffer hopper (that could be provided with antibridge swift) made of stainless steel
- Dosing device (screw conveyor, vibrating chute, gear pump) with continuously adjustable speed.
- Scale with load cells and signal amplifier
- Control system (PLC) that could drive until 15 feeders simultaneously.
GSBI developed a control system that allow the feeders control by means of PLC available in the market (Allen Bradley) avoiding the requirement of dedicated electronic cards or microprocessors, granting the following advantages:
- Reliability, performance and spare parts are the same of the used commercial PLC.
- It is possible to include the management of loss in weight feeders in the PLC that control the raw material storage and conveying plant.
- Simple communication with supervision systems by means of most common standards.
Operator interface is a PC that allows a clear and friendly monitoring of the plant and a very simple process data management.
Also available in compliance with ATEX Directives - Category 3D. |
