Material Handling
  • Impact: To your conveyor and your business



    By putting springs inside the idler, we eliminate the inertia of the idler frame from impacting the absorption of the impact.

    From rail to sail: Aggregates distribution



    A rail-based distribution network beefs up material handling to meet demand.

    Self serve: Aggregates loadout


    Automatic blending and loadout systems designed as user-friendly solution.

    Pulley life



    Maximum pulley life is essential to effective material handling and high-capacity production. After all, you can make do without an idler or two, but, as for pulleys, you need them all. Those who have replaced a failed pulley know that it can take several hours or even a full day of downtime and maintenance labor.

    Pulley considerations



    Conveyor pulleys and components have design standards that are developed by the Conveyor Equipment Manufacturers Association (CEMA) and recognized by the American National Standards Institute (ANSI). Pulley designers use these parameters to develop a basis for their designs, which are largely based on shaft deflection. Design basics dictate that if the shaft deflection is limited to a particular amount based on load conditions, the pulley will withstand that deflection and load as well.

    Cost-cutting conveying



    Aggregate mining and processing facilities are becoming rare commodities in many regions. Consider that in the early 1980s, up to 27 percent of the nation's counties consumed more aggregate than they produced. By 2001, that statistic increased to 43 percent. Natural aggregates are in high demand where supply is short. This alone is changing the face of aggregate transportation within the processing facility, and from the pit to the point of use.

    On the waterfront



    Morse Brothers officials estimate that shipping by barge, rather than by truck, saves the company more than $3 per ton.

    A controlling interest



    When Rocky Mountain Materials & Asphalt Inc. (RMMA) erected its first computerized premixed concrete plant on the east side of Colorado Springs, Colo., its goal was to take complete control over the concrete production process, from material delivery through the creation of a quality mix.

    A clean sweep


    A switch to lower-cost conveyor wiper blades solves a downtime problem for an Illinois earthmoving project.
