The invention relates to a computer-aided method and a device for controlling a concrete mixing plant for the production of ready-mixed concrete (1) or mixed concrete, which is mixed at least from the components cement (6a; 6b) and aggregates (8a, 8b, 8c) with the addition of water (9) in a motor-driven mixer unit (3), wherein at least the required mixing time (t.sub.M) of the mixer unit (3) is calculated before the start of the mixing process by means of an electronic prognosis unit (10), which calculates the current moisture (F), measured by means of at least one moisture sensor (11), of at least the aggregates (8a, 8b, 8c) to be added and the temperature measured by means of at least one temperature sensor (12;13;14) or thermal imaging camera, in order to determine the required mixing time (t.sub.M) of the mixer unit (3) on the basis of a predetermined concrete formulation (18), taking into account the various measured values determined by the sensors.

A load measurement system for a mixer comprising a mixing drum configured to contain and mix concrete, a cradle adjacent to the mixing drum and configured to receive the mixing drum, and a load measurement device adjacent to the cradle and configured to determine the changes to a material property of the cradle due to the force exerted on the cradle by the load in the mixing drum. The load measurement system determines the amount of the load of concrete in the mixing drum based on the measured change to the material property of the cradle, which may include one or more of a material deformation, displacement, stress, strain, or the vibration of the cradle.

Asphalt mixing plant, comprising a mixing drum and a temperature monitoring system, the temperature monitoring system comprising a temperature sensor configured for contactless measurement of a material temperature of an asphalt mix to obtain at least a first temperature value for at least a first point of time, where the temperature sensor is arranged at an area of an output of the mixing drum or at a discharge chute of the mixing drum; and an operation and monitoring unit and a remote server; whereby the operation and monitoring unit is configured to wirelessly transmit the at least first temperature value to the remote server via a wireless communication interface unit.

The present disclosure provides for a reversible and adjustable stopper assembly comprised of an upper frame, L-bracket, connector portion and stopping member. The stopper can be configured to be secured to at least two main types of press brakes. The stopping portion of the stopper is also reversible, allowing for less sheet metal to be inserted into the press brake, if desired. The stopper assembly can be slid in a horizontal manner, relative to the press brake to preserve the measurement of the sheet metal from one end of the press brake to the other.

The present invention relates to a process for producing a foam ceramic comprising the steps: producing an aqueous suspension of a first mineral raw material; foaming the suspension with air while adding a foaming agent and a binder to form a light foam; mixing the light foam with a powder or slip of a second ceramic raw material to form a heavy foam; pouring the heavy foam into a mold; drying the molded heavy foam in the mold to form a solid foam; and firing the solid foam in the mold to form the foam ceramic.

Mobile mixing devices, mobile mixing systems, and related methods are provided. A mobile mixing device can include a frame and a mixing drum securable to the frame. The mixing drum can include a body that forms an internal cavity and can have a forward end and a bottom end. The mixing drum can also include a mouth at the forward end of the body that provides access to the internal cavity of the mixing drum. The mobile mixing device can include a heater support arm having a heater secured to an end of the heater support arm that is distal from the mixing drum. The mixing drum can be used to process cement material when the heater support arm is in a stow-away position or asphalt when the heater support arm is in a heating position with the heater facing into the mouth of the mixing drum.
