Electric control is the ideal way to control the development of goals, while addressing the basic control and fine control problems Raymond. Electric mill demand will gradually increase. In recent years, at home and abroad have been successfully developed a new type of electric adjustable rolling mill distance. Was equipped with a stepper motor and chain drive mechanism consisting of Raymond 3r, either with the original hand wheel adjustment, can also be controlled by setting the requirements for remote computer operation. Stepping in intermittent or continuous rotation of the way quickly rolled away from the fine and quick adjustment, it could go from the control panel, press the setpoint for closed loop automatic control. Reasonable grader shell body design which is related to the shape and scope of the Raymond area classification chamber. If the classifying chamber is too small, the powder will be diffusely reflected in the classifying chamber, the swirl becomes very turbulent Raymond 4r, affecting the normal classification. Grading room if too large, the classification of particles less than a full role by centrifugal force, prone to slip and not be completely drawn into the vortex inside. Raymond addition, the shape of the classifying chamber should have the leading role downstream, help qualified powder into the impeller, substandard meal return mill regrinding.
