When planning a bulk materials handling operation, it is very important to choose the right machines to do each job. Machinery has evolved into extremely efficient “tools of the trade” since the pick and shovel. Today, belt cleaners are engineered machines, each carefully designed to fulfill a specific task. However, the mindset of many managers responsible for choosing belt cleaning systems is still in the days of the pick and shovel. So when you are planning to choose cleaning system for your conveyor, you need to consider the following facters:belt cleaner

  •   Cleaner Types
    1.  1. Primary or pre-cleaners are installed on the face of the head pulley below the material trajectory, useing a urethane blade to remove the overburden of material from the belt.
    2.  2. Secondary cleaners are installed at the point where the belt leaves the head pulley or along the returnto remove fines and sticky clays. Shock absorption is built in the cleaner or tensioning device, allowing metal belt splices to pass without damage.
    3.  3. Tertiary or final cleaners should clean grooves, cracks and abrasions in the belt cover while removing water.
    4.  4.The criteria to choose belt cleaning systems should be as carefully developed as the considerations for selecting a continuous miner, roof bolter or underground equipment.
  •   How Clean Is Clean
    1.  1. The first thing to consider is the operation’s goals for the cleaning system. You may want a belt that won’t drop “too much” material, or you may need a belt that is “white glove” clean. Are you trying to keep regulatory agencies – EPA, OSHA, MSHA, State DEQ or neighbors? or is your goal to reduce cleanup labor and improve idler life? And most importantly: given the realities of maintenance budgets and staffing, what level of cleaning will you accept?
    2.  2. It is best to know – and spell out – in advance what the goals are for the performance of a cleaning system.
  •   Conveyor Characteristics
    1.  1.Belt speed
    2.  2. Belt width
    3.  3.Type and condition of splices
    4.  4.Specifications of the belt, including manufacturer, and cover thickness
    5.  5.Clearances to install and service cleaners
    6.  6. Drift Back
  •   Characteristics of Conveyed Material
    1. 1. Abrasiveness
    2. 2.stickiness
    3. 3.Moisture content
    4. 4.Corrosives
    5. 5.Lump size
    6. 6.Tons per hour
  •   Cost and price

Finally, the issue of cost must be considered. Too often, price is the first criteria to be evaluated when purchasing a component. It is better to place this issue at the end of the selection proces when purchasing a cleaning sustem.
