About the Gentle Roll™

Higher Quality, Higher Productivity, and low Maintenance Costs are just a few of the many advantages of selecting the Gentle Roll™.

To understand why the Gentle Roll™ so reliably sorts your product into its particle sizes without damage, think of a Gentle Rolling action which is continuously moving forward, exposing the product to the screen without damaging it.

The screens make up an outside wall, and the entire assembly rotates as a unit.  As it turns, your product rolls over continually and moves through the tube or falls through a screen and is separated according to size. Your product can be scalped, cleaned, sorted, or graded in one continuous operation.

The natural rollover action removes fractured parts or embedded particles from your good product.  It's just a gentle roll-over action. Smaller particles fall through the first screen and larger sizes continue to pass over, or through subsequent screens or to be discharged at the end.

This gentle system of rotational sifting tends to prevent clogging or blinding of screens. Most particles that might be temporarily caught in a screen will usually fall back when that part of the screen reaches the top of the rotation.

A few materials have a slight tendency to cling, sometimes requiring some cleaning of screens. Simple EBM Manufacturing solutions are working well without damage to products. In some applications, rotary brushes may be used to maintain optimum screening efficiency powered by the screen rotation.

Standard Gentle Rolls™ cannot be overfed or underfed. The unit will purge itself if left running for a short time after feeding stops. Special designed Gentle Rolls™ which are equipped with a special feeder have to be control fed or they will plug.

The cylindrical shaped screens are very easy to remove or change. Up to five classifications may be achieved on a four screen version by installing a different mesh screen at each section or the same size of screens can be used on more than one section when more screening efficiency is required.

Animal and human food processors are seeing dramatic improvements in product quality after replacing vibrating and shaking cleaners with the Gentle Roll™.  Conditioning of pellets and extruded products while removing fines when using Gentle Rolls™ has added value to their products. Gentle Rolls™ concentrated gentle rollover action with induced gravitational force created by its rotary motion removes fractures and flashing from their product which otherwise ends up as fines on their final product.

With Gentle Roll™ installations, owners are enjoying efficient, reliable operation with lower maintenance, less down time and far less time for changing screens.

Since there is neither unbalanced rotation, reciprocating or vibrating parts, structural support can be significantly lower in cost. Buildings, footings, or adjacent equipment will not be subjected to vibration and harmonic energy forces. Because the weight of the Gentle Roll™ is static, any unit can be installed almost anywhere within a facility, even at the top of an exterior tower. There is no need to build extra-heavy and beefed-up structures or footings as vibrating machines require. You need only to consider static weight and wind loads in the design of your support structures.

Your Screening or Sifting Application is Special!

Gentle Roll™ offers a wide range of options and flexibility to provide a design that will fit your unique application exactly.

Gentle Roll™ units come in one to five screens. Because the Gentle Roll™ is VIBRATIONLESS and its weight is static, any version of the Gentle Roll™ may be safely mounted almost anywhere in or on top of your facility.

Whatever configuration or task you assign to your Gentle Roll™, it is not necessarily a permanent one. You can change the operation mode and results by changing screens and redirecting or combining the outputs.

The diagram below shows a four screen version with collecting hoppers. Fines are removed with two screens, good product goes out screens 3 and 4 and overs discharge out the end.

In addition to hopper collectors for fitting to product distribution systems, numerous other variations of feed and discharge equipment are available to handle any product or by-product in a manner appropriate to its physical character.
