A commercial auger conveyor is an efficient way to move raw materials from one area to another with little to no spillage. However, screw conveyors can develop or create other problems. Here are some ways to solve some of the more common issues you may encounter.
Dust in the atmosphere can be a serious hazard. It can make it difficult for employees to breathe and may lead to respiratory problems. In addition, some types of dust are combustible and can present fire hazards in the workplace.
With the movement of powders or finely ground materials, a great deal of dust can easily be created. This calls for the use of the right kind of seals and gaskets. What may work for some materials may not work for others. One should consider gasket material which can be greatly compressed. In addition, flanged covers may provide the kind of protection you need from dust.
Auger conveyor clogging can be a serious issue. This is especially true if you are moving wet or sticky materials. In this case, standard screw conveyors may not be the answer. One solution for this is to add gentle heat to the auger for better movement of material. Cheese is one material that slides much easier through a heated auger system. Stainless steel construction is the material of choice for food applications and can easily be heated if designed into the system. Another option is to go with shaft-less screw conveyors as this can eliminate any clogging issues.
If your auger conveyor is working hard to move sand, cement materials or anything which can be abrasive, this can greatly add to the “wear and tear” factor of your conveyor system. Average carbon steel can quickly become worn down and this will greatly reduce its life expectancy. One way to combat this is to use high carbon abrasive resistant steel alloys for increased toughness and hardness. The mining and wood products industries are two that benefit from using high carbon steels. Another option is the use of nickel based alloys that with the addition of molybdenum and chromium for increased resistance to both abrasion and corrosion. The wood pulp industry finds benefits in conveyor equipment made of these alloys. The use of specially coated shafts and troughs is yet another way to resist the abrasion caused by these materials. By employing one of these methods of combatting abrasion, a longer conveyor life, less downtime and fewer maintenance issues can be enjoyed.
If you are trying to make your old auger conveyor system perform work that it was not originally designed for, it can present a number of problems in the future. Instead of modifying and retrofitting, you may be much better off with a custom designed screw conveyor system. Astro Engineering & Manufacturing has years of experience with these systems and takes all the issues you will encounter into account when designing the perfect conveyor for your applications.
