CMC Inc - Conveyor System & Components - CONSTRUCTION MACHINERY CANADA

Conveyor Systems & Components

Custom built conveyors made to provide material flow to suit production needs. CMC uses premium heavy duty components (bearings, rollers, motors, gear reducers and conveyor belting/buckets) to ensure maximum system performance & reduce plant down-time.

Bucket Elevators

Bucket elevators are an efficient way to elevate bulk materials while utilizing a minimum plant footprint.

Typical bucket elevator consists of:

an inlet chute
a series of buckets mounted on a belt or chain that are pulled over a head pulley (top) and tail pulley (bottom) bottom of the bucket elevator
a vertical steel casing and a discharge chute

Take-ups on the tail pulley shaft provide a means of tensioning the conveyor belt and when it stretches. The steel case supports the head pulley and provides an enclosure to contain dust and provide weather protection.

The capacity of a bucket elevator is controlled by a combination of the speed of the belt or chain, and the number and size of the transfer buckets. Further fine control is accomplished by controlling the input into the bucket elevator at the inlet.

Advantages of a Bucket Elevator:

variable capacity achieved via bucket size/number and speed of conveyor belt
small footprint raises materials in a safe, clean manner
discharge height is adjustable without changing bucket elevator footprint
case supplies complete enclosure and weather tightness, reducing dust and noise
controlled feed reduces spillage

Features:

crown faced drum or wing pulley

CASING

heavy guage construction to suit your application
jig welded with continuous seams and structural angle iron flanges
oversized bolt-on inspection doors

DRIVE

heavy duty gear reducer with oversized shaft and bearings
heavy duty back stop to prevent back legging

Screw Conveyor or Auger

Custom made to provide material at the rate that your production requires.

totally enclosed to prevent exposure to weather & contain dust particles
move materials horizontally or vertically
incline slope determines capacity | lower incline increases capacity

Available options:

tube or trough types
multiple inlet &/or discharge points for distribution
reversing with double outlets

Features:

over sized TEFC motors
heavy duty gear reducers & bearings
belt or direct drive with appropriate safety guards
progressive pitch flighting at conveyor inlet
construction materials | heavy wall tubes, abrasion resistant steel wear areas

Belt Conveyor

Custom designed to customer specifications.

For longer conveyors, take-ups are required to:

adjust the alignment of conveyor belt via screw type take-up
maintain belt tension via gravity take-up

Gravity take-up advantages:

reduces slippage with proper tension at head pulley for wet materials
ensures proper slack-side tension is maintained
Straighter belt run, reduces chance of catching & belt damage
reduces material spillage off belt by maintaining proper contour & material position
automatically compensates for belt stretching
allows for storage of excess for replacement splices
absorbs most shock resulting from conveyor starts/stops, reducing stress belting, splices & bearings

Shuttle Conveyor

Features:

heavy duty construction with high quality bearings, rollers and reducers
hardened, machined wheels on heavy duty track
heavy duty chain drive and motor reducer

cast aluminum construction - corrosion resistant
red epoxy coated actuation arm shows which belt is turned off in a multiple belt application
Nema 4, dust tight and rain proof enclosure

Conveyor Belt Guide | belt conveyor

Maintain conveyor alignment, preventing costly conveyor belt damage and splice tear out.

Mount top or bottom of conveyor frame
10" of vertical adjustment to accommodate different sized head and tail pulleys
3" of horizontal adjustment to accommodate different belt widths
designed for troughing rollers (20/35/45 degree) or return rollers (0 degree)

Universal Belt Guide:

heavy duty mounting plate with standard hole patterns for rollers support brackets
urethane guide roll with permanently greased bearings

Vertical Divider

Pinch Guard | belt conveyor
Prevents clothing or hands getting caught in rotating return rollers
Easy to install
Meets OSHA requirements complete with warning labels

mount using return idlers bolts
available for standard belt widths with either a 1 1/4" or 4 1/2" drop
available for 4" & 5" rollers

Troughing Roller | belt conveyor

Offset Troughing Rollers are used to carry or convey conveyor belts loaded with bulk materials

Off-set center roller helps to lower overall height of belt as well as helping to maintain conveyor tracking
