Compaction Tables

Construction

All Palmer compaction tables are manufactured in our well known, foundry-duty format for years of use and abuse. Heavy wall steel tubing and plate steel are used in all fabrications. The rugged steel frame is fabricated from integrally interlinked 1/2" steel plate. The lift bar assembly is fabricated from 5/8” x 8” steel with an interlocked rib system welded solid to a 5/8" steel base plate.

The lift bar assembly is actuated by pneumatic air bags, each with a capacity of 850 lbs. and a maximum stroke of 2”. In the elevated position, the lift bars extend above the roller conveyor approximately ½”.

All Palmer compaction tables feature easy access for cleaning and maintenance.

All Palmer compaction tables are built to fit your conveyor specifications. All we need to know is the roller diameter, height, and spacing between the rollers to manufacture to fit existing systems.

Vertical Vibrators - Linear Tables

The vertical vibrators are used to obtain the optimum compact ability of molds and cores. The vibrators provide an infinitely adjustable level of output force while maintaining the high frequency that is critical for the correct no-bake compaction.

Reversing Vibrators - Rotary Tables

Reversing vibrators are used to obtain the optimum compactability of molds and cores. The reversing vibrators provide a different level of output force for each direction of rotation. The use of two of these vibrators produces four different output force levels while maintaining the high frequency vibration that is critical for the correct compaction.

Controls

All vibrator controls and time relays are housed in NEMA 12 enclosures. All reversing motor starter and timer relays will be housed in the main electrical enclosure.

The cycle start button and the force selector rheostat are located at the operator control box. 

Operation 

The mold/core box is rolled onto the table rollers and filled. Prior to striking off, the operator presses the cycle start button. The air bags inflate, lifting the core/mold above the rollers the vibrators run the amount of time set on the timer located inside the enclosure. Once the vibrators stop, the air bags lower the core/mold to roller conveyor surface for striking off.

Options

• Flat Top – with or without airbag
• Lifting Bars
• Gravity Conveyor
• Powered Conveyor
• Reduced Decibel Level Option – reduces force output 6% while reducing sound from 107 db to 85 db per vibrator.
