How it works

Hapman Solidquid Powder and Liquid Slurry Delivery System

Save time, energy, maintenance, and floor space. Unlike traditional mixing applications that use a liquid-filled tank with dry product dumped on top, the Solidquid system needs no additional mechanical conveyors, and you can save money by connecting to existing liquid delivery equipment. Tank mixing systems have several motors that run various pieces of equipment required to properly move and blend dry and liquid components. The Solidquid slurry delivery system uses the motive liquid and engineered venturi to effectively produce a slurry mixture.

The Solidquid has only one motor that runs the feeder; fewer motors mean less maintenance and lower energy costs. Plus, Solidquid’s small footprint takes up less floor space and offers more flexibility in equipment layout.

The powder is metered into the wetting cone that feeds the eductor. A portion of the motive stream is tapped before the eductor and used as a washdown on the wetting cone. This mitigates the opportunity for material to cling to the side of the hopper and maintains a liquid level within the cone, reducing the amount of entrained air and aiding in maintaining discharge pressure. The motive liquid stream enters the eductor through a converging nozzle, creating a high-velocity jet. Liquid leaving the converging nozzle expands in the discharge horn, generating a vacuum that draws the material from the wetting cone into the eductor. The powder is entrained, forming a slurry.

General Rules of Application

  • It is best if the motive fluid viscosity is below 100 centipoises.
  • The ratio of liquid to solid achieved in a single pass averages 10 wt/wt%. Higher concentrations are possible with different flow and pressure rates but may require a recirculation loop when higher concentrations are required.
  • Powder additions that raise the viscosity above 400 centipoises are discouraged.
  • Solidquid systems are not able to handle non-Newtonian fluids.

Our Solidquid solid-liquid slurry system has a two-stage design. Stage one creates a vacuum which helps to suck powders or granulates into the eductor. Stage two disperses solid components into the liquid phase. These application examples illustrate the versatility and power of this equipment.

This configuration can be used in a wide variety of applications. Here the Helix is feeding dry material into the inlet hopper of the PosiPortionTM Feeder. The feeder is metering the dry product into the wetting cone of the Solidquid system.

Slurry made using a Vacuum Conveyor to storage tank

In this application example, our Vacuum Conveyor is used to easily convey material right from the supply barrel or bag into the eductor of the Solidquid. The slurry is conveyed up into the holding tank using the pressure from the slurry delivered from a Hoist and Trolley Bulk Bag Unloader.

Optimal efficiency is achieved in this system. The bulk material enters the delivery process through the use of an electrically operated Hoist and Trolley Bulk Bag Unloader. The material flow is enhanced with the optional pneumatic bag agitator, allowing the material to flow in a free form through the discharge valve and into a LumpMaster® Lump Breaker. Clumps in the material are broken down to ¾” size or less and delivered to the inlet hopper of the PosiPortion volumetric feeder. The feeder then meters the dry material into the Solidquid slurry delivery system. The vacuum created in the Solidquid system effectively blends the solid and liquid and moves the slurry downstream.
