4-Auger Horizontal Feed Mixers
Auger Horizontal Mixers from Herd-Boss
Auger Mixers are a type of Horizontal feed mixer and differ from Reel style mixers in the mechanics used to mix the product. Each style has its own advantages depending upon your applications and requirements. This page offers insights on which model is right for your needs. Herd-Boss manufactures a wide range of auger mixers to accommodate your feed requirements.
Overview
The Herd-Boss Auger Horizontal Mixer is the choice for a thorough and efficient blending of the most common beef and low roughage dairy rations. With a unique 4-auger mixing chamber featuring an unequal belly height and raised auger design, these mixers promote a complete and gentle blend of ingredients with fewer fines and dead spots.
Increasingly, today’s producers use rations that contain large amounts of protein and by-products, resulting in a denser ration. A greater density ration means the mixer must accommodate more pounds of feed per cubic foot. The Auger Horizontal HDR models (4750 & 4900) have been developed specifically for these high-density rations. The HDR models incorporate an increased torque capacity and other design enhancements to meet the demands of these high density rations.
Standard Features
All of our Auger Type Horizontal Mixers feature a design that promotes a complete and gentle blend of ingredients with fewer fines and dead spots and the ability to mix all types of rations. Additional features include:
