Electric Shaker Conveyor Systems

Shaker conveyor systems, also known as vibratory conveyors, are mechanical devices used to transport materials in a controlled, horizontal motion. These systems utilize a shaking or vibrating action to move products along a conveyor path, making them ideal for handling bulk materials, parts transfer, and scrap removal.

Shaker conveyors are known for their durability, energy efficiency, and minimal wear parts, which contribute to their long lifespan and low maintenance requirements. They are commonly used in industries such as food processing, manufacturing, and recycling.

PRI carries shaker conveyor systems from PAX and MPI.

PAX Electric ShakerS

Pax's patented EGD conveyor is an electrically driven, oscillating type conveyor that utilizes a motorized, elliptical gear drive (EGD). Utilizing elliptical gears in a sealed oil bath provides an extremely reliable drive and a high conveying speed at lower RPMs.

The EGD conveyor is currently available in three sizes, rated based on the total tray weight, excluding the weight of the parts and scrap on the trays.

Features

Quick and Easy Tray Attachment

Tray brackets simply snap in place over the round portion of the crossbar without the use of tools. The machined, Acetal brackets bolt to the side of the conveyor tray can rotate on the crossbar if the tray needs to run on a slight angle.

Electrically Driven, Elliptical Geared Drive

The elliptical drive gears are bathed in oil inside of a sealed gearbox. This arrangement minimizes the reverse inertia effects that create issues for many other conveyor designs.

No Air Consumption

The EGD conveyor is electrically driven which means that it does not have the high operating costs and ongoing maintenance issues that are associated with many air-driven conveyors.

Optional, Quick Release Arm Arrangement:

To provide increased access to the press, this quick-release option allows the operator to simply lift the arm, (crossbar), off of the unit and to re-install the arm by simply placing it back on the top of the unit. No tools are required to remove or replace the arm.

T- Slot Type Mounting Brackets:

Bracket bolts to the bottom of the EGD-50 and is arranged to attach to standard T-slots. Standard brackets are based on a vertical mounting surface of 5.25”, (this is the height of the vertical plate on the bracket).

Brackets are available for different T-slot sizes and spacing as shown below, (contact Pax for detailed dimensions of the required bracket).

EGD-050-6190-0: ¾” T-Slots on 6” spacing, bar widths of A = 0.72” and B = 1.38″.

EGD-050-6192-0: ¾” T-Slots on 12” spacing, bar widths of A = 0.72” and B = 1.38”.

EGD-050-6191-0: 1” T-Slots on 6” spacing, bar widths of A = 0.97” and B = 1.50”.

EGD-050-6193-0: 1” T-Slots on 12” spacing, bar widths of A = 0.97” and B = 1.50”.

 Vertical Face Mounting Bracket (PN EGD-050-6194-0):

The bracket bolts to the bottom of the EGD-50 and is arranged to be bolted to a vertical surface (such as the face of a bolster plate). Standard brackets are based on a vertical mounting surface of 5.25”, (this is the height of the vertical plate on the bracket). Contact Pax for detailed dimensions.

Option of Utilizing an Extruded Aluminum Cross Bar in Place of Pax’s Standard Cross Bar:

For customers with standardized extruded aluminum-type cross bars, an extruded aluminum bar can be attached directly to the top plate on the EGD-50. To attach the extruded aluminum bar, four ¼” bolts can be inserted through existing holes in the top plate and connected to T-nuts that can be inserted into the extruded aluminum bar. Top plate is designed for a 1.5” x 3” extrusion that has a 1.5” spacing between T-slots and a T-slot opening of 0.32”.

MPI M-M10000 Electric Shaker Conveyor

M-10000 is a complete central scrap removal system custom designed for your plant operations.

MPI’s M-10000 Series High-Capacity Floor Mounted Electric Shaker Conveyor (US Patented) is designed to transfer scrap metal, bulk products, or bulk materials reliably over long horizontal distances. The horizontal motion conveyor is designed to transfer at rates of over 10,000 pounds per hour and distances of hundreds of feet. The shaker conveyor features a formed steel pan that is driven by a single drive at a smooth, low frequency to convey materials in a horizontal motion.

Rugged enough to be used in applications for scrap conveyors, including scrap removal conveyors, press scrap conveyors, and scrap removal systems, the system reliably transfers the most destructive materials (i.e., scrap metal, castings, and rocks). However, the shaker conveyor's movement is gentle enough in their movement to transfer potato chips, nuts, or biscuits without breaking them.

The M-10000 Series is often integrated as part of a complete turnkey system that includes other components, such as incline conveyors, other horizontal motion conveyors, and controls. In the stamping industry, these make up one component of an underground scrap system or central scrap handling system used to collect and transfer scrap metal from stamping presses.

M-10000 Features:

• Reliable Maintenance Free Conveyance
  • Low frequency, smooth horizontal motion conveyor single pan systems reliably transfer scrap or parts in a horizontal motion.
  • Metal on metal contact points are eliminated with maintenance free, Rubber Suspension Technology (RST) bearings  Supporting the pan and connecting the drive. RST bearings require no grease or maintenance.
  • Uniform pans contain scrap or parts and reliably transfer them from conveyor to conveyor.
• Indestructible Pans
  • Steel pans are more rigid and take less damage from scrap or parts compared to other conveyor designs
  • Jams caused by scrap or parts are eliminated because pans are formed from a single sheet of steel, creating a uniform surface for the length of the conveyor
  • If damaged, pans can typically be repaired or replaced in-house,reducing the need for outside vendors to help get equipment back up and running.
• Flexible, Modular Design
  • Flexible configurations and options allow users to optimize and configure the system for their application.
  • The pans, drive, and pan supports are modular to scale up and down for each application and easy to replace should damage occur, maximizing uptime.
• Safer Operation
  • Pinch points are eliminated with the single pan design and the short stroke of the drive makes the system safer to work around compared to other conveyor designs.
• High ROI
  • Lower maintenance costs and higher uptime deliver a quick return on your investment.
• Turnkey Support
  • MPI's team has the expertise to support each major step of the integration process, including onsite assessments, drawing review, component integration, scheduling for installation, installation supervision, and installation.
