Installation may require additional equipment if installed with Air Chest Divider option. Standard on all Maxi-Cap Gravity Separators and Destoners, Voyagers, and all Hi-Cap Master Series machines.

Air Chest Dividers

These vertical air dividers enable more accurate air control over the adjustment of individual fans driving weighing air through the deck. A great upgrade for machines built prior to 1991.

Cordura Boots

Cordura is a synthetic material that is built to last. It has high tensile strength fibers and will withstand long term wear. It’s also extremely water repellent. You will find the boot in two locations. First if applicable, you’ll see it attached to the dust hood and deck rails. Second it will be attached to the under carriage and air chest. A dual locking, re-closable fastener is what holds it to the machine. Making it simpler for operators to open and reseal.

Scalp Screen

The scalp screen is an optional scalper specifically designed to eliminate clumping to applied seed treatments. Under variable treatment rates and different applications liquids may cause clumping or sticking. Some materials are more prone to this cohesive bonding which may make the flowability of particles more difficult. The scalp screen has the ability to completely rid of clumping and sticking.

Discharge Hopper

All hoppers are customizable to your separation solutions. We offer square or round discharge outlets, sized 4” and 6”. Spouting is easily attached to round outlets on your Oliver machine.

Rock Trap Discharge Gate

Heavy contaminants side discharge gate allows precise metering of heavy discharge and easy periodic flush (discharge) of heavy material accumulating in rock traps or the high side of the machine. The spring-loaded design operates with an adjustable wheel for raising the gate to allow discharge. Alternately, the wheel can be left closed, and the slide can manually lift against the spring. Infinitely adjustable for particle size. Available for all Hi-Cap Destoners and Gravity Separators

Power Blender

The motorized Power Blender rapidly conveys the heaviest product to the discharge hopper—improving capacity and eliminating the wear and strain associated with earlier rod-driven blenders. The blender significantly extends operating life and promotes smooth, trouble-free operation.

Aspirating Feeder

Aspirating feeders provide an economical means of removing light contaminants before the particles are delivered onto the separation deck. These feeders are generally capable of handling moderate dust problems. If you do not already have an adequate in-house air system, a system can be ordered complete with fans, drives and bag filter system.

Vibratory Product Feeder

Vibratory feeders assure consistent product flow on materials that tend to bridge at the intake. They can be installed with or without a Dust Hood to assist in uniform product flow, which is critical to separation efficiency. The vibratory feeder can be controlled through a manual adjustment or integrated controller via the touchscreen on Maxi-Cap Platinum and Voyager Gravity Separators.

Accu-Flo Feed Gate

This electronically controlled pneumatic actuator can be infinitely adjusted for uniform feed rate. It has a screw adjustment for flow control and pressurized air line for positive shut off (pictured is a combined Accu-flo and Aspirating Feeder configuration).

Adjustable (Heavy-Side) End Gates

Located on the heavy fraction of the discharge end of the deck. Under certain operating conditions it is beneficial to utilize these gates in order to manipulate the separation in the means according to your product(s) standard. For example: pushing more product to your middle fraction in order to sift out unwanted product on your heavy side.

Horizontal Release Gate

Built into the deck rails is the Horizontal Release Gate. Designed specifically for releasing material from the heaviest layer of your product. The Horizontal Gates are ideal for separation of larger capacities as it can better control the material flow. For best results controlling the discharge of heavy particles from the separation deck, Horizontal Release Gate accomplish effective balance and improve operator precision. For fastest adjustment when variable capacities and separation decisions occur throughout the processing day.

Corner Cutoff Plate

The triangular stainless-steel Corner Cutoff Plate is positioned on the deck feed end, high side corner. Installation of this plate improves product distribution, and better manages airflow for separation. Easily retrofittable.
