Abstract
A double disk pulp grinder comprises a foundation support, a body, a main motor, a main shaft, an outer grinding area composed of an outer movable grinding disk and an outer fixed grinding disk and an inner grinding area composed of an inner movable grinding disk and an inner fixed grinding disk, wherein a rotating disk is fixed on the main shaft, the outer movable grinding disk and the inner movable grinding disk are fixed on the rotating disk, the inner fixed grinding disk is fixed on the body. The double disk pulp grinder is characterized in that the outer fixed grinding disk is fixed on a movable seat which is connected with a rotary element of a feeding and withdrawing mechanism. The axial movement of the movable seat is realized by the rotating movement of a hand wheel or a feeding and withdrawing motor, thereby realizing feeding and withdrawing operation and meeting operational usage requirements of different users. A pneumatic lifting means is additionally arranged on the body, when the double disk pulp grinder stops, the main shaft is actuated to move axially in the left direction, thereby ensuring the interval between the inner movable grinding disk and the inner fixed grinding disk to be larger than 2 mm, and preventing the grinding disks from being broken when the pulp grinder starts next time. When mounting the double disk pulp grinder, a vibration damper is disposed between the foundation support and the factory building floor, and thereby influence of equipment vibration to a factory building can be minimized.
