Mixing apparatus having a frame on which a mixing tank is mounted and extending vertically. A hammermill carried on the frame receives and chops different types of feed material. The resulting product is then deposited in a transfer conveyor which transports the material to the mixing tank. A mixing assembly within the tank circulates material to produce a well mixed homogeneous mass. The mixing assembly comprises upper and lower material advancing portions, the lower of which includes a conical shaped core member converging upwardly. One or more rigid crop engaging elements extends outwardly from the lower edge of the core member to enhance the effectiveness of the mixing apparatus.
