A major step in selecting the right equipment for your specific process involves identifying the properties of the material you are handling or moving. Can your material withstand high temperatures? Can it be exposed to air or water? Is it explosive or corrosive? Answering these questions and others like them provides valuable information used in the conveyor design process and supplies us with the details we need to ensure both the quality of your product and the safety of your employees.
Abrasion – The handling of abrasive products requires a complete understanding of the nature of the product as well as identifying the component that will likely last the longest. When handling abrasive products, no mechanical equipment will last forever. Our goal is to provide the longest life possible. To this end, we will typically oversize the equipment and slow it down. By reducing the contact surface areas and the speed at which the equipment and the material contact each other, we are able to reduce wear. Selecting the correct components and construction material is also vitally important. Different grades of AR steels and hardening, as well as selecting the correct seals to protect bearings, drives, and other external components, must all be considered during the design and manufacture of equipment that will handle abrasive material.
Temperature – The ambient temperature in your facility, the temperature of the material being handled, and potential changes in the characteristics of that material influence the selection of the materials we use to construct your equipment. For the components, temperatures over 160°F/70°C will require us to review each component to make sure the correct lection is being made. As for the material being handled, an example is that the melting point of a certain material is at 340°F/170°C. Yet, we find that the material begins to smear at 200°F/93°C. For our design consideration, we need to be concerned with designing around the lower temperature when the material actually begins to change.
Sluggish vs. Free-Flowing Material – How your product flows is a primary concern in the design of your equipment and system. Will it feed well or will flow aids be required? Will it discharge easily or are devices required to assist? Will the material bridge or will it flow like water? Knowing the exact flowability of your product provides us with the information necessary to fine tune your system with features that will provide the optimum performance.
