Double-Slope High Volume Rotary Feeder

When it comes to moving massive volumes of material such as dry powders,
granular materials, small rocks or other types of abrasive materials with
relatively uniform material size and low moisture content, Precision’s
Double Slop High Volume Rotary Feeder is the preferred choice!

A metering device and a high-capacity airlock all in one!

DOUBLE SLOPE ROTARY FEEDER

KeyFeatures

Workplace

1

Application Specific:

Every Rotor and Barrell are perfectly mated up to meet the specifications of the application. Precisely machined to operate within the specified temperature and at the optimum throughput.

2

REBUILDABLE!

The only truly rebuildable rotary valve in the industry! Built for outage to outage functionality. Minimal maintenance ensures this unit meets your expectations! Able to be rebuilt, refreshed and reused!

3

Upgrades & Accessories:

A variety of upgradeable options exist so your new feeder can be perfectly equipped for your specific application.

4

Pairs:

The PMRD is usually installed in pairs because these critical systems like to have lots of throughput a plenty of redundancy.

5

Rotor:

A 6-pocket straight rotor vane, rounded pocket arrangement allows this unit to maximize throughput! The PMRD is built for SPEED!

6

Double Slope:

This rotary feeder is built with THROUGHPUT in mind! No knife, double-slope maximizes efficiency and keeps material flowing. Engineered for high temperatures!

7

Surface Hardened:

Depending upon the size, optional surface hardening is available to provide additional abrasion resistance!

8

HD Bearings:

Equipped with high load outboard tapered roller bearings, which are heavy-duty, industrial grade to ensure proper shaft alignment.

DOUBLE SLOPE ROTARY FEEDER

Key Advantages

Built to withstand the beating! Precision’s Double Slope Rotary Feeder is manufactured with abrasion-resistance built in! Built from specialized materials to maximize the component life while decreasing maintenance costs.

The Double Slope Rotary Feeder is a superior value on large volume applications due to the sheer volume of materials this feeder can delivery on very revolution.

If abrasion-resistance is at the top of the list, a simple upgrade to manufacture this unit from special, domestically sourced alloys with a hardness range up to 500 Brinell should do the trick!

The Double Slop Rotary Feeder is perfect for granular materials or dry powders requiring throughput deliverability in excess of 50 tons per hour.

PMRD ROTARY FEEDER

Designed For Performance.Built To Last.

  • Fabricated housing with an integral mild steel or Tri-Braze barrel; barrel thicknesses from 5/8” to 1-1/8” thick depending on feeder size.
  • The barrel is precision-bored to a concentric, known diameter to provide a true fit with the rotor.
  • All barrels are overlaid with an industrial hard chrome, the typical thickness is 0.005” to 0.009” depending on feeder size – provides the first-line defense against abrasive wear.
  • Two rotor configurations available depending on the application:
    • 8-vane, closed-end helical rotor
    • 6-vane, closed-end, straight-vane, rounded-pocket rotor
  • Feeder inlet is a double-slope design with replaceable Tri-Braze wear plates bolted to each inlet slope.
  • The endbells include adjustable brass seals to minimize the possibility of pressurized air migration past the rotor end in pneumatic applications.
  • Heavy-duty Dodge piloted flange bearings installed outboard of the housing to isolate heat, moisture, and dirt from the bearings.
  • Nord, SEW, or Sumitomo shaft-mounted gear-motor drive packages for clean, safe installations providing direct application of power with options for variable speeds and other functions.
