Jet Hopper

The TR Jet Hopper is a standalone mud mixing hopper for feeding dry drilling fluid additives into the circulation system. It uses Venturi jet mixing to draw barite, bentonite, salt, and other dry additives into the drilling fluid.

An external pump supplies the pressurized drilling fluid required for jet mixing. The hopper itself does not include the pump or manifold of a complete mud mixing unit.

Advantages of Mud Hopper

1. Direct dry additive feeding. Feeds powdered additives directly into the drilling fluid.

2. Venturi jet mixing. Draws dry additives into the fluid stream and disperses them during mixing..

3. Wear-resistant replaceable nozzle. Withstands abrasive drilling fluid and high-velocity flow and can be replaced after wear.

4. Easy circulation-line connection. Connects to an existing drilling fluid circulation line.

5. Flexible Mounting. Supports high-level and low-level installation.

Jet Hopper Structure

• Hopper body: Holds the dry additive.

• Jet nozzle: Produces the high-velocity fluid jet.

• Tee mixing chamber: Brings the additive into the drilling fluid.

• Venturi tube: Carries the mixed fluid from the mixing chamber.

• Butterfly valve: Controls the additive feed.

• Reducing adapter: Connects the drilling fluid inlet to the jet nozzle.

Working Principle

An external pump sends drilling fluid through the jet nozzle. The high-velocity flow creates the suction needed to draw the dry additive from the hopper.

The additive enters the Tee mixing chamber and mixes with the drilling fluid. The combined flow then passes through the Venturi tube and returns to the mud circulation system.

The pump flow and pressure should match the selected Jet Hopper. Insufficient flow can reduce the suction effect and result in poor additive feeding.

A centrifugal pump is commonly used to supply the required flow. A shear pump can also be used when additional shearing is required during additive mixing.

TR Jet Hopper Technical Specifications

Applications

• Oil and gas drilling

  Adds weighting and other drilling fluid additives during mud preparation and treatment.

Jet Hopper Selection

Select the Jet Hopper based on fluid flow, inlet size, operating pressure, additive type, and installation arrangement. DN100 generally suits lower-flow circulation lines, while DN150 is suited to higher-flow requirements.
