    • An internal mixer having a floating weight disposed in contiguous with an internal mixer main body and made elevatable in a hopper to which a material to be mixed is charged, wherein a hydraulic cylinder for elevating the floating weight is disposed in contiguous with the internal mixer main body, a pneumatic/hydraulic pressure conversion means for pressure conversion between a hydraulic side and a pneumatic side is disposed separately from the internal mixer main body, and the hydraulic side of the hydraulic cylinder for lowering the floating weight is connected with the hydraulic side of the pneumatic/hydraulic pressure conversion means. The reliability of the internal mixer can be improved while making the structure compact and facilitating the maintenance operation.

    • An internal mixer and controller enables the phase difference and the speed ratio between two rotors to be changed without stopping the operation of the mixer. The internal mixer comprises: nonintermeshed first and second rotors disposed in a mixing chamber; first and second drive units; first and second phase measuring devices; first and second speed measuring devices; and a control unit for controlling the first and second drive units on the basis of signals from the first and second speed measuring devices and signals from the first and second phase measuring devices. The control unit controls the two rotors so as to synchronously rotate at the same speed on the basis of the signals from the speed measuring devices when the two rotors fixedly rotate at the same speed. When the phase difference between the two rotors is changed, the control unit calculates the phase difference from the signals from the phase measuring devices, compares the calculated phase difference with a set phase difference, and controls the second drive unit to change the speed of the second rotor, thereby changing the phase. When the phase difference is equal to the set phase difference, the control unit again controls the two rotors so as to synchronously rotate at the same speed on the basis of the signals from the speed measuring devices. When the two rotors are rotated at different speeds, the control unit controls the drive units so that the speed of each of the rotors is equal to the set speed, respectively, on the basis of the measured speed from speed measuring devices.
    • 内部混合器和控制器使得可以改变两个转子之间的相位差和速度比,而不停止混合器的操作。 内部混合器包括:设置在混合室中的非接合的第一和第二转子; 第一和第二驱动单元; 第一和第二相位测量装置; 第一和第二速度测量装置; 以及控制单元,用于基于来自第一和第二速度测量装置的信号和来自第一和第二相位测量装置的信号来控制第一和第二驱动单元。 控制单元控制两个转子,以便当两个转子以相同的速度固定旋转时,基于来自速度测量装置的信号以相同的速度同步旋转。 当两个转子之间的相位差改变时,控制单元从相位测量装置的信号中计算相位差,将计算出的相位差与设定的相位差进行比较,并控制第二驱动单元改变 第二转子,从而改变相位。 当相位差等于设定的相位差时,控制单元再次控制两个转子,以便基于来自速度测量装置的信号以相同的速度同步旋转。 当两个转子以不同的速度旋转时,控制单元控制驱动单元,使得每个转子的速度分别基于来自速度测量装置的测量速度等于设定速度。

    • A hermetically closed kneading apparatus includes a casing member (1) having a chamber (2) and one pair of counter rotating, parallel rotors (3) (4). Each of rotor has three long blades (18) (19) (20) and of which the central axes (17a) (17b) of the rotors are set apart from each other so that the long blades may not mesh with each other. Each of the long blades extends spirally around the central axis (17a) (17b) of the rotors and are set apart from each other by an equivalent angle in a circumferential direction of the rotor. Each rotor has a profile corresponding to any one of the following features: (a) the profile is almost triangular. (b) the profile includes a straight line in each non-action (22) surface of the rear surface (26) of each blade with respect to a rotation direction, the straight line starts from edge (18a) of a tip (21) of each blade (18). (c) the profile includes any one of an approximately gentle concave line, an approximately gentle convex line and an approximate straight line in each rear surface (26) of each blade with respect to a rotation direction, and the rotors have a maximum diameter Dr and a minimum diameter Dd of which the ratio falls in a range of 0.5
