Abstract:
One example of correlating energy to mix well cement slurry under laboratory conditions to field conditions can be implemented as a method to determine energy to mix cement slurry. Electrical power supplied to an electric mixer in mixing a specified well cement slurry is measured. An energy to mix the specified well cement slurry is determined from the measuring. The determined energy to mix the specified well cement slurry and specifications of field equipment for use in mixing the specified well cement slurry at a well site are compared. The field equipment is a different configuration than the electric mixer. Based on the comparing, it is determined whether the well cement slurry needs redesigning according to capabilities of the field equipment.

Abstract:
Disclosed is an apparatus and method for providing asymmetric oscillations to a container. The container may include a fluid, a particle, and/or a gas. A vibration driver attached to the container provides asymmetric oscillations. A controller connected to the vibration driver controls an amplitude, frequency, and shape of the asymmetric oscillations. An amplifier amplifies the asymmetric oscillations in response to the controller. A sensor disposed on the vibration driver provides feedback to the controller.

In order to provide a feed mixture, a feed mixer is proposed which has a container. The container has a bottom and a wall which is connected to the bottom and delimits a filling opening, the area of which is greater than the area of the bottom. A rotatable auger is provided which can be rotated about an axis, the axis running substantially perpendicularly with respect to the bottom. The feed mixer has a pivoting device which is intended and suitable for pivoting the container during a mixing operation, in particular after a predefined time period or after a predefined number of revolutions of the at least one auger.No new matter is added.

Abstract:
A control method and control system for an agitating mechanism are provided. The control method includes receiving a load current detected by a current detecting apparatus when the agitating mechanism is rotating along a specific direction; determining whether the rotation of the agitating mechanism meets a preset trigger condition based on the load current; and controlling the agitating mechanism to rotate in a direction opposite from the specific direction when the trigger condition is met. The present invention can reduce the possibility of the electrical components of the agitating mechanism being burnt out and prolong the lifespan of the agitating mechanism. The present invention can improve agitation results of the agitating mechanism. At low speed, the agitating mechanism can perform the agitation gently without damaging the texture of the solid food. At high speed, the agitating mechanism can more homogeneously and finely agitate the mushy food with enhanced agitating efficiency.
Abstract:
Displacement sensors are configured so as to be capable of measuring relative displacement along the axial direction of an outer ring-fixing member, which is for fixing the outer ring of one end of a bearing, or a casing with respect to an inner ring-fixing member, which is for fixing the inner ring of the one end of the bearing, or the rotor. A load-calculating unit calculates the thrust load acting on the rotor by multiplying the relative displacement measured by the displacement sensors by a conversion coefficient.

The techniques described herein provide, in one embodiment, a rapid-agitation mixer for food products that comprises a product holder configured to hold a sealed product cup containing a food product to be mixed, and a drive shaft along an agitation axis, the drive shaft configured to secure the product holder and product cup in place. The illustrative mixer also comprises a drive motor configured to reciprocate the drive shaft in opposing directions, where the product holder correspondingly reciprocates the product cup to churn the food product within the product cup.
Abstract:
When kneading kneading materials that include raw rubber and carbon black in a closed-type rubber kneader, the extent of the kneading efficiency of the closed-type rubber kneader is evaluated in accordance with the magnitude of the evaluation index calculated from unit work/total amount of shear by calculating an evaluation index calculated by a calculation device based on a total amount of shear obtained by integrating the shear velocity applied to the kneading materials by a rotor that is being driven to rotate by the rotor drive unit of the kneader over the kneading time, and a unit work obtained by dividing the integrated power obtained by integrating the instantaneous power of the rotor drive unit over the kneading time by the mass of the kneading materials.
Abstract:
An apparatus for mixing a viscous flowable medium includes a receptacle for receiving the viscous flowable medium and has a substantially vertically arranged rotatable stirring axle and a stirring assembly that comprises at least one stirring element. In one embodiment, the stirring element is arranged at a lower end of the stirring axle substantially perpendicular thereto for rotation of the stirring element around the stirring axle. The stirring elements are shovel-like and are open towards an end of the stirring axle remote from the lower end and inclined with a slant angle in rotation direction towards a bottom of the receptacle, such that said viscous liquid upon rotation of the stirring axle is at least partly directed upwards in the receptacle by the at least one shovel-like stirring element.
