  • Patent number: 6786629
    Abstract: A method for continuously mixing a borehole fluid such as cement includes using a measurement of the solid fraction of a cement slurry as it is being mixed to determine the ratio of the solid and liquid components to be added to the slurry. A system for mixing the slurry includes a liquid material (water) supply including a flow meter; a solid material (cement) supply; a mixer which receives the liquid and solid materials and includes an output for delivering materials from the mixer to a delivery system; a device for measuring the amount of material in the mixer; and a flow meter in the output; wherein measurements from the flow meters and the device for measuring the amount of material in the mixer are provided to a control system which provides control signals to automatically control the amount of solid and/or liquid material added to the mixer.

  • Publication number: 20040033308
    Abstract: The invention relates to a method for producing a bitumen-bonded construction material mixture, such as rolled asphalt, where mineral matter is coated with bitumen that is sprayed onto the mineral matter. So as to have to heat the mineral matter only to a temperature T1 with 110° C.≦T1≦160° C., a water-containing additive is mixed in, which is added immediately before and/or during and/or immediately after spraying the binding agent.

  • Patent number: 6676862
    Abstract: A method and apparatus for efficiently forming individual building units is provided, generally includes providing a plurality of molds, each capable of simultaneously forming a plurality of building units. Batches of cementitious slurry are individually mixed in order to control the density of each building unit formed. The ingredients are individually measured and combined into the mixing device. The cementitious slurry is then conveyed or transported and poured into one of the molds. The method provides the ability to control the amount of cementitious slurry in each batch in order to control to the extent possible the quantity of cementitious slurry poured into each mold and the ability to precisely control the dimensions of each building unit produced.

  • Publication number: 20030227814
    Abstract: Producing both colored and noncolored lightweight aggregates. The processes involve mixing a lightweight fine material such as ash with cement, and optionally pigment, then agglomerating the mixture, curing, and sizing the lightweight aggregate. Calcium stearate is added to the lightweight aggregate for reducing the moisture permeability of the lightweight aggregate end product. The colored and noncolored lightweight aggregate may be used in a variety of ways such as to provide a lightweight concrete mix with the same exterior and interior color, and for other asphalt pavement, geotechnical, horticulture, and specialty uses.

  • Patent number: 6638344
    Abstract: A filter vent system and method for separating entrained airborne particulate matter from the conveying fluid is disclosed, particularly as it relates to filling a storage vessel. The filter system employs a simplified, yet more efficient filter cleaning arrangement, in which the entire clean air plenum on the downstream side of a filter array of one or more filter units is periodically pulsed with a large burst or pulse of relatively high pressure air from a single source which rapidly raises the plenum pressure to, in turn, produce a temporary pulsed flow reversal in the filter units which blasts through the filter pores to displace particulate matter collected on the upstream side of all of the filter units alike thereby cleaning or re-generating the filter surfaces.

  • Patent number: 6607298
    Abstract: A concrete mixing plant, with an aggregate storage to which a central part is fixed forms a transportable concrete station. In the concrete mixing plant there is a conveyor that transfers the aggregate to the aggregate mixer component, the mixer component containing the mixing equipment with its batching and weighing devices. A connecting unit is attached to the lower part of the mixer component with a joint, and to the upper side of the central part with a second joint. The jointed frame is attached with the top joint to the upper part of the mixer component and with a bottom joint to the top at the back of the central part. As a result the mixer component can be lifted from the transporting position to the mixing position and lowered to the transporting position, retaining all the cabling connections.

  • Publication number: 20030094574
    Abstract: A method of determining liquid absorption of an aggregate comprises providing a sample of the aggregate, adding liquid to the sample, subjecting the sample to a light source signal, monitoring a light reflected signal reflected from the sample and controlling addition of liquid to the sample as a function of the light reflected signal. The apparatus comprises a support for supporting a sample of the aggregate, a liquid source for adding liquid to the sample, a light source which subjects the sample to a light source signal, a light sensor which senses a reflected light signal reflected from the sample and a processor/controller which controls addition of liquid from the liquid source as a function of the reflected light signal. The light source is preferably an infrared source and the light sensor is preferably an infrared detector.
