Evaluating chains by Application

  1. 1. Evaluating chains<br />For Packaging Applications<br />www.nercon.com<br />920-233-3268<br />
  2. 2. Wash-down<br />High pressure water and chemical cleaning create a wet, caustic environment which affects chain selection.<br />Sanitary Conveyor<br />Cleaning agents will attack Acetal chains; Polypropylene chain material is preferable. <br />
  3. 3. COLD<br />Cold temperatures from 32 degrees F to 0 degrees require special chain material.<br />Ice Cream Line<br />Acetal chain material and pins are rated for cold temperatures.<br />
  4. 4. FREEZER<br />Freezer Room Conveyors<br />Proper chain selection is especially critical in freezer rooms to reduce maintenance and manpower in these harsh environments.<br />Acetal chain is preferred, with Nylon pin material. <br />
  5. 5. warm<br />Applications ranging from 70 degress to 200 degrees F, such as conveying through heat tunnels and shrink banders.<br />Heat Tunnel<br />A variety of metal chains are available in warm environments; heat resistant nylon chains are also available depending on exposure. <br />
  6. 6. Elevatedtemperature<br />Applications operating in environments over 220 degrees F.<br />Oven Infeed Conveyors<br />Metal chains are required with brass wearstrips. <br />
  7. 7. chemical<br />Chemical spillage environment or extensive chemical used in the cleaning process.<br />Bleach Leak Test Conveyors<br />For constant chemical exposure, stainless steel chain and pins are recommended.<br />
  8. 8. Electro-static<br />Aerosol Can Line<br />Static build-up is caused by friction, especially plastic chains running plastic containers.<br />Static causes safety hazards.<br />Anti-static chain material allows the static to safely discharge through the conveyor to the floor. Lubricating conveyor surfaces is another method of reducing static.<br />
  9. 9. Explosive<br /> Ammunitions Conveyor<br />Volatile fumes in an electro-static environment can lead to an explosion.<br />Products with an explosive make-up such as ammunitions, for example.<br />Stainless steel chain with brass wear-strips, and explosion-proof motors. <br />
  10. 10. AbrasIVe<br />An abrasive environment is caused by the product on the conveyor (dust build-up, broken glass, baking flour, cereal) or by the conditions in the plant.<br />Sugar Handling Line<br />Stainless steel sprockets and abrasion resistant rods will help to increase belt life. <br />
  11. 11. PLASTIC CHAIN MATERIAL<br />Polypropylene: A standard, relatively strong chain material for general applications. It has chemical resistance to many acids, bases, salts and alcohols. It may be somewhat brittle used in cold temperatures.<br />Polyethylene: Offers high impact strength and flixibility with resistance to fatigue. It is also resistant to many acids, bases and hydrocarbons.<br />Acetal: Is stronger than polypropylene and polyethylene with a good balance of mechanical, thermal and chemical properties with low coefficient of friction.<br />Nylon: Can be used in place of standard Acetal for impact intensive applications. Nylon, however, does absorb water and is more susceptible to damage than Acetal.<br />
