Thomas & Muller - Bulk Materials Handling and Conveying Equipment

Thomas & Muller Systems Ltd. has over fifty years of experience in the design, engineering and fabrication of custom mechanical bulk materials handling and conveying equipment.

Over the years we have gained invaluable experience and knowledge that we are able to draw on when designing new equipment and systems. We also work with customers on how to correct, change or improve their current systems or equipment, when handling their materials, to improve the service life of the equipment. We also repair damaged and worn equipment when cost effective.

Thomas & Muller Systems Ltd. specializes in the design, engineering, and fabrication of custom equipment and systems. The equipment and systems that we design, engineer, and manufacture are screw conveyors, screw feeders, multiple screw feeders, live bottoms for bins, hoppers or silos, cantilevered screws, single and double shafted pug mill mixers, blenders, dewatering screw conveyors, belt conveyors, bucket elevators, drag conveyors, bins, and hoppers etc.

What has set us apart from competition is working with our customers to completely understand their needs and what they are trying to accomplish. Our experience goes back to the early 1960s.

There are many reasons and applications which require variation to standard screw conveyors. Material characteristics and desired processing during conveying are two of the most common reasons that non-standard screws and housings are needed. All screw conveyors are volumetric in their conveying of all materials, therefore all calculations for capacity of a screw are in "cu ft per hr".

BELT CONVEYORS

A belt conveyor has several advantages and disadvantages when being considered as a mechanical means of bulk materials conveying.

BUCKET ELEVATORS

A bucket elevator is a very economical way to elevate material, in both large and small quantities. There are several types and styles of bucket elevators. The selection of type and style depends on the material to be conveyed, its qualities and characteristics, the desired capacity and amount of lift.

CANTILEVERED SCREWS

A cantilevered screw can also be designed as a screw feeder. A cantilevered screw is usually a short screw since in its design the deflection of the screw is always calculated to insure that the screw does not rub on the housing when running. The drive shaft of a cantilevered screw is always supported by two bearings with the screw projecting out from the shaft inside the housing, to the end discharge.

DRAG CONVEYORS

A drag conveyor is a good way to move material in one direction when a change in elevation is desired. It can also be used as a metering device if the inlet of the drag has a strike off as the material leaves the inlet. The style of chain and flight for the drag conveyor is determined by what material the drag is moving and whether there will be a change in elevation.

INCLINE SCREW CONVEYORS

A screw in the horizontal is a conveyor or feeder, but as a screw is inclined it very quickly becomes a lift or pump. All of the charts and formulas for calculating speed and capacity for a screw in the horizontal are no longer applicable, what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for incline and vertical screws.

RIBBON SCREWS

Ribbon screw conveyors are used for several reasons. The two most common are for handling sticky materials and material that tends to segregate during conveying. The proper ribbon screw conveyor design will eliminate the segregation of large from small and light from heavy.
