"Scalping" Mash in the Production of Animal Feed

 
Introduction
Producers of poultry and livestock feeds frequently receive cereal grains such as oats, barley, wheat, corn, etc. in bulk shipments, and removal of contaminants is desired prior to placing these ingredients in storage silos. Many producers take the added precaution of screening the finished product before the bagging operation. As the mill processes the cereal grains with additives to produce a finished feed, mash traces of impurity such as paper labels may be accidentally incorporated. Kason VIBROSCREEN Separators are widely used in both applications.


Method and results
Single-deck 48" diameter Kason VIBROSCREENS are used with screens having openings from 1/3" to 3/4" depending upon the individual mill's requirements. The quantity of oversize removed is extremely small, but the unit will accept feed rates of up to 60 TPH, the exact capacity being related to bulk density of the feed being handled. The product discharge frame is equipped with special discharge spouts designed specifically to handle this high flow rate. On final mash "scalping," a Kason is frequently installed directly above automatic weigh scales.


Features
1. Even though the screening application described here is extremely simple, the capacity obtained (up to 5 TPH per square foot) is significantly higher than that possible on other types of vibrating screens. Impurities are rejected completely free of product.

2. Installation above automatic bagging machines frequently requires minimum headroom, and it is only necessary to have 3 feet to install a Kason.

3. Many feed mills are of simple wooden construction and the Kason's light weight (approximately 650 pounds) and complete absence of transmitted vibration allows for simple installation without special foundation requirements.

4. Stainless steel screen cloth is used, and since the method of mounting eliminates wire flexing or other forms of mechanical damage, replacement is infrequent and the cost of operating the machine is negligible.
