There was a lot to see and do at PACK EXPO International 2022. With over 44,000..
Matcon design and manufacture a range of unique discharge valves to control the flow of bulk powders and overcome the risk of powder flow problems such as bridging, ratholing and segregation.
At the heart of our valves is Matcon's world-famous Cone Valve Technology delivering efficient and flexible powder handling solutions, serving a range of powder manufacturing industries.
Matcon is the original manufacturer of Cone Valve Technology and can provide solutions for a wide range of applications to enhance your materials handling capabilities and transform your powder handling processes.
Invented, patented and developed by Matcon, the original Cone Valve Manufacturers.
Our Cone Valve technology allows manufacturers to handle a wide range of powders, bulk materials from cohesive to free-flowing.
The Cone Valve overcomes all of the typical powder handling problems associated with butterfly valves and silo hoppers, such as bridging, blockages, mix segregation and core-flow. This impressive discharge device also provides accurate, automatic and controlled discharge of virtually any powder type, achieving what other systems cannot.
Gain control of your powders with the Matcon Cone Valve.
The Cone Valve is at the heart of the Matcon IBC systems. It is essentially a discharge and flow device.
It sits at the outlet of the Matcon IBCs or Discharger Valves and can be configured with variable lift heights or levels of vibration, to overcome all powder handling issues and control powder flow.
The Cone Valve creates mass-flow discharge with ‘first-in first-out – FIFO’ flow, maintaining the homogeneous blend.
With an automated discharge procedure, it can be operated across floors or at height and linked to level probes in the downstream equipment.
Blended materials can be fed directly from the IBC, discharging to the downstream process with minimal risk of mix segregation protecting the reliability of the end product.
Cohesive powders and materials can be stimulated to flow, without the risk of particle rolling or segregation, which results in better product quality and less scrappage.
Powders that are 'free-flowing' can be controlled and dosed to specified weights without the need for additional feeders, which would add cost and complexity to a system.
Fragile ingredients and materials such as flakes, candy, or gum are gently handled and breakages are avoided.
Shut-off of the flow of materials during discharge is possible and enables a switch out of IBCs that still contain product, without the risk of product leakage.
Dust-free handling and containment are assured throughout processing removing the risk of cross-contamination hazards – ideal when manufacturing allergen-containing products.
Designed for fitting to silos and hoppers to equip them with Cone Valve technology, Discharger Valves deliver a controlled discharge of bulk powders.
The Discharger Valve acts as both a flow aid, metering device and shut-off valve in one.
Feeding of dry bulk powders to a downstream process such as extruders or loss in weight feeders is controlled and ensures a consistent and reliable source of material.
Every material has different powder characteristics and each application needs a specific flow or feed rate, so it is helpful to have support from our experts who have the knowledge and experience to ensure you get the right sized valve for your application
With sizes ranging from 500mm to 2.5 metres in diameter, the Discharger Valve is designed with a flange in order to be easily mounted to the silo, hopper or bin outlet.
The internal cone houses a pneumatic vibrator which is deployed as the cone lifts into the powder material and is used to stimulate the flow of bulk solids. Rubber isolators limit any vibration transmission into the surrounding plant.
An actuator driven by compressed air provides the lift force to raise the internal cone which is enclosed within a hygienic cover.
The internal Cone Valve promotes mass flow as it rises into the powder material, and pulls material from all sides of the vessel, preventing rat-holing and bridging.
An adjustable lift height allows metered, controlled dosing.
Manufactured from 316L stainless steel it can be used in almost any industry application.
Robust and reliable design with easy access panel for maintenance.
Easy to install and retrofit to existing silos, hoppers and bins to overcome powder discharge problems.
Discharge device - the powerful lifting and vibrating action of the cone valve easily overcomes bridging, ratholing, and other flow problems. A major benefit of the Cone Valve is that it promotes 'mass-flow’. Pulling material from all sides of the vessel. This helps to eliminate particle segregation should the powders in the silo or hopper be a mixed blend.
Valve - because it opens and closes vertically the cone valve can be shut off at any time to stop the flow of product. Other types of valves cannot close effectively once the flow has started. The valve closes under gravity and the weight of material overhead, thus is totally failsafe.
Feeding device - because it can be controlled so easily, the Matcon Discharger Valve is frequently used to meter material from storage, either at a controlled rate or to a level sensor or to a specified weight.
As the Cone Valve lifts, it creates an annular gap through which the powder flows freely under gravity. This proven design ensures that you avoid powder handling issues such as:
