Conveyors

CTM SYSTEMS - CONVEYOR SYSTEMS - MATERIALS HANDLING, PROCESSING & STORAGE SOLUTIONS.

CTM design a whole range of bespoke conveyors including belt conveyors, both troughed and flat belt.

All of these conveyors are tailor made to suit the individual application such as length, material handled, throughput, horizontal or inclined, method of being fed, cantilevered stockpiles or simply supported, fixed or mobile, with our without inbuilt access walkways and platforms.

They can be from mild steel galvanised, painted or stainless steel if the environmental conditions dictate, stringer or lattice frame construction as the load bearing capacity dictates.

Belt conveyors can either be supported by rollers or a slide bed.

They can be troughed or flat in either case with the belt chosen to suit the materials being carried.

They are generally fitted with rubber covered drive drums, plain tension drums and snub drums if a high degree of wrap is required to transmit high power or torque.

The drives can either be shaft  mounted, vee rope or chain driven.

Discharge chutes and feedboots are designed to suit the materials being handled and come in a variety of materials and thickness to suit.

Scraper design is carefully considered and these are a major influence on the performance of any belt conveyor – they can be from the simple Rosta mounted Vee thane single bladed to the multi bladed adjustable tungsten tipped variety – again dependent upon the materials being handled.

All conveyors come with their respective support structures or they can sit on our clients existing structures,  full general arrangement drawings are always issued together with imparted loads to either steelwork or ground such that the civil requirements can be fulfilled.

CTM conveyors can be a variety of widths or lengths currently from 400 to 2000mm wide and up to 150m or more in length.

Special belts can be used to convey at steeper angles up to 30 degrees (chevron belt), plain belts can generally convey up to 20 degrees dependent upon the materials being handled, a pocket belt design can be supplied to convey horizontally, vertically, horizontally in as many “steps” as the site constraints dictate.

We also do a range of Intralox or Volta belt conveyors that employ those belts in the food industry for hygiene and to ensure they always track on centre.

Reversible belt conveyors can be supplied with a central loop drive as can shuttle belts to achieve a moving stockpile discharge.

Storeveyors (typically used in the petfood industry) can be supplied designed to provide a moving “live buffer” of 30m3 or more of materials with a first in first out basis to ensure the product is fresh when conveyed onto the next stage of the process.

 

 

CTM also design a whole range of bespoke screw conveyors, both shafted and shaftless.

All of these conveyors are tailor made to suit the individual application such as length, material handled, throughput, horizontal or inclined, method of being fed, single or multiple outlets, cantilevered stockpiles or simply supported, fixed or mobile.

They can be from mild steel galvanised, painted or stainless steel if the environmental conditions dictate, stringer or lattice frame construction as the load bearing capacity dictates.

If the screws are shafted we endeavour to keep the support bearings external to the casing by using a large centre tube able to span the distance but in the event the screw is very long, either journal hangar bearings or ball bearing hangars are used if the design allows.

If the screw is shaftless, they are generally supported on PE1000 full length liners and the with the absence of a centre shaft, the screw flight itself is generally  a lot thicker to compensate (typically 25 – 30mm).

The drives can either be shaft  mounted or foot mounted/chain driven.

All conveyors come with their respective support structures or they can sit on our clients existing structures,  full general arrangement drawings are always issued together with imparted loads to either steelwork or ground such that the civil requirements can be fulfilled.

CTM conveyors can be a variety of diameters currently from 150mm to 1200 mm wide and up to 30m or more in length.

Special design screws can be used to convey at steeper angles up to 30 degrees  dependent upon the materials being handled.

Screws can be carbon steel, Hardox or Abro for hi wear resistance, stainless steel for food quality or high tensile in the case of the shaftless design.

They lend themselves well to convey dirty material where non spillage, odour containment and hygiene is considered an important aspect of the design.

They also require less maintenance and take up less room than a belt conveyor.

Screw conveyors can be designed to impart a mixing action as well as a cooling function to hot materials typically exiting a dryer or thermal process such as gasification, incineration or pyrolysis process.

The coolers can be twin or triple screw if required to create sufficient surface area to cool the product within as it is conveyed down the length.
