Abstract

An internal mixer has the mixing devices inside a body, a loader closed off by a ram, and an inlet with at least one opening which can be closed off; the ram moves vertically in the inlet and is moved hydraulically by a piston, piston rods, cylinders and a control device. This control has an inlet and outlet for the hydraulic liq., lines for the upward and downward motions of the ram, connection between these two lines, outlet to the restricted return line for the liq., a pressure accumulator connected to the inlet, a contraction line and connected second accumulator plus valves between the lines; these valves permit the various settings ''move ram up'', ''move ram down'', ''hold ram in top position'', ''hold ram in bottom position'', ''mixing'' etc. When the setting is ''mixing'' the contraction line can be connected with the second accumulator to the second ram line whilst the first ram line is connected to the first accumulator.
