ABSTRACT:
A sampling mill for grinding discrete materials to obtain a representative sample is provided by this invention. The mill is particularly useful for grinding various foodstuffs such as corn, peanuts, animal foods and the like. The material to be sampled is fed to a rotary worm gear of substantial length connected to a burr plate to feed the material between a second plate. By varying the worm gear with comminuting means, the placement of burrs on the burr plate and the distance between the burr plates, the size of the ground sample can be varied and different types of foodstuffs can be ground and sampled as compared to a grinder with limited adjustability. The ground sample is distributed to a main discharge chute and a sampling chute with an adjustable valve to provide a selected small percentage of the total ground foodstuff.
