Dense Phase Abrasive Hopper

Dense Phase Hoppers are typically used with Jet Edge's precision waterjet cutting systems. Their large capacity makes them ideal for industrial use.

The Dense Phase Hopper is available in a wide range of capacities, from 440 lb (180 kg) to 6000 lb (2220 kg).

Jet Edge's Dense Phase Hopper (also known as a solid phase hopper) waterjet abrasive delivery system uses compressed air to create an even distribution of abrasive flow that is essential to achieve reliable cutting results. This system is used in most factory settings and employs a secondary metering system.
 
For solid phase delivery, a pressurized hopper is used to force a solid stream of abrasive to a single cutting head or to multiple cutting heads. Each cutting head can be individually controlled to achieve its predetermined abrasive ow rate through the use of a secondary metering hopper. The secondary hopper has a pneumatically actuated slide gate that provides accurate metering and reliable on/off control of the abrasive. The metering system consists of a dial wheel (four wheels available) with various holes that can easily be changed to achieve the desired flow rate of abrasive to the cutting head.

 

A CUT ABOVE
Using compressed air, the Dense Phase Hopper creates an even distribution of abrasive flow that is essential to achieve reliable abrasive waterjet cutting results. Its large storage capacity supports hours of uninterrupted abrasivejet cutting.
 
The Dense Phase Hopper can supply abrasive to single or multiple abrasive waterjets.  Each cutting head can be individually controlled to achieve its predetermined abrasive flow rate through the use of a secondary hopper (also known as a mini hopper). The secondary hopper has a pneumatically actuated slide gate that provides accurate metering and reliable on/off control of the abrasive. This metering system consists of a dial wheel with various holes that can easily be changed to achieve the desired flow rate of abrasive to the cutting head.
SUPPORTING EQUIPMENT

The Dense Phase Hopper requires a customer-supplied air compressor for operation.  Input Flow 80–90 psi (5.5–6.2 bar), 11 cfm (0.311 m3/m) minimum.
