Abstract
An apparatus for kneading particulate to granular materials comprising a container in the form of a bottomed hollow cylinder, a vertical shaft disposed in the center of interior of the container and rotatable by a motor assembly, pivotal arms mounted on the vertical shaft and turnable only upward and downward, agitating rolls rotatably supported by the pivotal arms each at one end of the arm and each having a recessed outer peripheral pressing surface, and pressure adjusting assemblies each provided between the vertical shaft and the other end of each of the pivotal arms, the pressure adjusting assembly comprising a cylinder member, a rod and means housed in the cylinder member for biasing the rod in directions opposite to each other.
Claims6
A kneader for particulate or granular materials comprising:
- a container having the shape of a bottomed hollow cylinder;
- a vertical shaft rotatably mounted in the center of the interior of the container;
- roll carrier means having agitating rolls rotatably mounted thereon, said roll carrier means being pivotally mounted on the vertical shaft for causing said rolls to move upwardly or downwardly by pivotal movement of said roll carrier means;
- and
- pressure adjusting means connected to said roll carrier means for varying the pressure applied to the agitating rolls in accordance with the level at which the rolls are positioned, said pressure adjusting means having a cylinder member, a rod slidably extending into the cylinder member and having a flange at the end within the cylinder for dividing the interior of the cylinder member into two chambers, and means disposed in the respective chambers for biasing the rod in opposite directions when said flange is moved from a neutral position in said cylinder member, one of the cylinder member and the rod being connected at one end portion thereof to the vertical shaft, the other of the cylinder member and the rod being connected at the other end portion thereof to said roll carrier means.
A kneader for particulate or granular materials comprising:
- a container having the shape of a bottomed hollow cylinder;
- a vertical shaft rotatably mounted in the center of the interior of the container;
- roll carrier means having agitating rolls rotatably mounted thereon, said roll carrier means being pivotally mounted on the vertical shaft for causing said rolls to move upwardly and downwardly by pivotal movement of said roll carrier means;
- and
- pressure adjusting means connected to said roll carrier means for varying the pressure applied to the agitating rolls in accordance with the level at which the rolls are positioned, each of the agitating rolls having a recess in the peripheral surface thereof extending circumferentially thereof for inhibiting the material being kneaded from slipping out from under the rolls.
