Flight Brush Edging

Flight Brush Edging

Maljohn Plastics flight brush edging has bristles clipped into a steel channel giving a brush type form. The steel channel of the ‘brush’ can then be tacked to the face of the flight allowing the bristle to extend passed the outer edge of the Screw Flights, providing a continuous ‘sweeping’ action along the length of the screw. Fitting Bristle Edging provides many advantages over a standard Screw Conveyor, especially when conveying delicate or brittle materials. The flighting keeps the material moving, while the bristle protects the delicate substance from irreversible damage.

Advantages of incorporating Maljohn Plastics flight brush edging in your Screw Conveyor:

  • Reduces material damage, without decreasing your screw capacity
  • Can perform in high-speed units
  • Custom-built to fit your specific application
  • Available bristle channels include mild, stainless, and galvanized

Hanger Bearing Inserts

Hanger Bearing Inserts

Durable polymer alloys capable of performing better than brass, bronze or babbitt!

  • Self Lubricating
  • Excellent for impact and shock application
  • Exceptional wear life and resistance to corrosion
  • Low temperature resistance to -80°F

When it comes to using plastics for various applications, it may become difficult to determine which material to use, especially with bearings and bushings. Below is a quick overview as to which plastic type is best suited for certain environments.

Flight Facing

Standard Flight Facing

Thickness is 3/8″ and we will do ½” thick as well

  • Flighting supplied as sectional flighting (they cover one full rotation)
  • They come pre-drilled and counter bored for either a UHMW capped elevator bolt or just regular mild steel elevator bolts.
  • Install on new flighting to stop wear or install to repair old worn out flighting
  • Low friction operation
  • Pre-formed to any diameter
  • Quick Installation
  • Can be made to increase diameter of auger for better clean out of trough

Available in other grades of UHMW, Polypropylene (for harsh acid resistance) HDPE, and other thermo plastic materials

Information Details required to order Flight Facing

  1. What is the diameter of your auger
  2. What is the pitch of Auger (Distance between Flights)
  3. Is the auger a left hand auger or a right hand auger
  4. What is the O.D. of the shaft that the flighting is welded to

Flight Edging (standard & extra depth)

UHMW Flight Edging (standard & extra depth)

Flight Edging is used to snap-on over the screw conveyor flight to extend the life of the flight and to allow for improved clean-out of the trough. It is normally installed by winding it along the screw so that it snaps on in the well between the flights and secured with metal rivets. Starting at one end the UHMW plastic is tapped into place by moving along the length of the screw. This Ultra-D plastic is stabilized against ultra-violet light radiation. The center bearing on short conveyors can sometimes be eliminated when the center of the screw sits lightly in the trough.

 

Material: UHMW (Ultra High Molecular Weight)

  • Install on new Flighting to save Edge
  • Repair old worn out edge
  • Provides better cleanout
  • Low friction operation
  • Pre-formed to any diameter
  • Quick installation

Questions to ask:

  1. Diameter of Screw
  2. What is the Flights Thickness
  3. What is the pitch of Auger
  4. How many feet is the auger (how long)
  5. Length of Auger divided by .3032 will give you the number of feet required of Flight Edging

Formed U-Trough Liners (Standard and Full Coverage)

UHMW U-Trough Liners

Material: UHMW (Ultra High Molecular Weight)

  • Out lasts steel 5 to 6 times longer
  • Liners are 1/3 the weight of steel
  • We pre-form liners for all size troughs
  • Liners are pre-drilled for 5/16” elevator bolts with 14 holes in a 4 foot length (7 per side) that start 1-1/2” down from top edge and 1-1/2” in from either end.
  • 45° beveled ends (each is beveled in the opposite direction)
  • our standard lengths are 4 foot long but we can do up to 12 foot long.

Reasons for 4 foot lengths:

  • Liners can ship by courier instead of common carrier which lessens freight costs
  • 4 foot lengths are easier to install
  • You will notice less buckling between fasteners (less expansion and contraction)

We have full coverage liners which mean the liners go all way up the top of the U-trough, and we have standard coverage which means the liners only go so many inches above the centre line of the U-trough. (This is our most popular) Our Standard thicknesses for U-trough Liners are 3/16”, ¼”, and 3/8” however we can also do ½”, 5/8”, ¾” and 1”

Other points to note:

  1. The products customer is conveying will not stick to liners, so you will eliminate bridging (hang-up problems)
  2. Product will flow easier because of lower coefficient of friction
  3. In turn means less power to convey product which:
    • Saves wear and tare on Drive systems
    • Saves Energy
    • Saves down time
    • Less waste
    • Saves you Money
