Grinding apparatus
First Claim
1. Grinding apparatus comprising:
- a mobile chassis;
a top opening tub for receiving materials to be ground, said tub provided with a rotatable sidewall and a non-rotatable floor and said tub pivotally mounted to said chassis for pivoting from a vertical position to a horizontal tilted position laterally transverse to the normal direction of travel of said chassis;
rotation means for rotating the sidewall of said tub;
pivot means for selected tilting of said tub, said pivot means having a rotational axis parallel with the direction of travel of said chassis;
material grinding means mounted to said chassis and extending upwardly through an opening in the floor of said tub for grinding material within the confines of said tub, when said tub is in the vertical position;
a bin mounted to said chassis below said grinding means for receiving ground material; and
conveyor means affixed to said chassis and rearwardly extending for conveying ground material from said bin.

Abstract
Grinding apparatus of the pivotal tub type with means for conveying ground material, said apparatus including a wheel mounted chassis; a tub, mounted on the chassis for receiving material to be ground, said tub provided with a rotatable side wall and a non-rotatable floor, and said tub being pivotal in a direction transverse to the direction of normal movement of the chassis; a grinder extending upwardly through an aperture in the floor to engage material within the tub; a bin for receiving ground material; and a conveyor system extendible rearwardly from the normal direction of movement of the chassis and foldable over the tub for compactness during transportation from site to site. The side pivoting tub, in combination with the extendible and foldable conveyor make the apparatus practical for movement on the highways. A deflector, mounted on the floor of the tub, lessens recirculation of ground material and prevents potentially dangerous material from flying from the tub in its engagement with the grinder.
