The manufacture of cement combines a variety of raw ingredients such as limestone, clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. The resulting raw mix is fed into a cement kiln which heats them to extremely high temperatures of about 1400 C to 1500 C. The abrasiveness of the material is a major factor on the wear of equipment and the extreme high temperatures of the process require specialized equipment.
Meyer has the engineering expertise, knowledge, and range of products to provide the right equipment for the cement industry. Meyer valves serve as airlock transition points, sealing pressurized systems against loss of air or gas while maintaining material flow between vessels with different pressure. Meyer valves are also widely used as volumetric feeders for metering materials at precise flow rates from bins, hoppers or silos into conveying or processing systems. The Flapgates are designed for high pressure applications and standard temperatures. These units are an alternative to rotary valves. In addition to our rotary valves and double-flap gates, Meyer screw pumps provide a large material throughput capacity utilizing a low-pressure, high velocity air supply. They are a rugged, dust-free replacement for many more fragile styles of pneumatic feeders. Thanks to a low profile it is an ideal feeder for applications with restricted head room. The screw pumps are designed for high pressure, high temperature, and highly abrasive material.
