MOTRIDAL - Chain Conveyors
Motridal manufactures drag chain conveyors for every industrial field: from low capacity chains to heavy duty high-capacity chain feeders and conveyors. These machines represent the most suitable solution for horizontal, inclined, or vertical transport of bulk materials, especially in the case of particular environmental needs or material characteristics (temperature, abrasiveness…). Motridal’s range of production includes both central chain and double chain conveyors, with forked link chains or round steel chains (for cleaning chains).
Central Chain conveyors
Motridal manufactures a wide range of central chain conveyors, with sizes up to 25”. The chain of these conveyors is made of drop-forged links in 18 NiCrMo 5 casehardened and tempered. Self-aligning “V-shaped” flights are welded to the chain links. These flights are rake the material, in order to prevent build-up along the bottom of the conveyor. This type of machine allows you to convey the material with horizontal and vertical paths simultaneously.
Double Chain conveyors
The size of double chain conveyors can reach up to 55”, thanks to the presence of two traction elements, which allow the use of longer flights. For these machines, Motridal uses special designed drop-forged forked links in 18 NiCrMo 5 casehardened and tempered. Flights are fixed by means of special pins to the chain links. The chain guides made in wear-resistant steel are bolted to the internal side of the conveyor casing.
Cleaning Chain conveyors
Cleaning chains are used to collect and recycle the material spilled from open conveyors (belt conveyors, pan conveyors, apron conveyors…) in order to reduce waste and environmental pollution. These machines are built with standard components (round steel chains, standardized drive and tail wheels…) and they each time are adapted to the plant. The use of standard components minimises the stock of spare parts required, reducing maintenance costs.
Special Purpose Chain conveyors
Ash Cooling And Conveying Systems: Submerged chain conveyors are usually positioned under the furnace throats in order to collect hot ashes. The ashes are cooled by water and conveyed along the horizontal section of the conveyor; then, along the sloping section, thanks to the slow speed of the chain, the water drains and the material is conveyed outside.
Chain Feeders: Chain conveyors are also used as discharging devices for silos and hoppers. In these conveyors the material is conveyed by the upper strand of the chain, thanks to a double bottom which separates the material from the return strand.
Vertical Chain Conveyors: Special-purpose chain conveyors, equipped with a false bottom, allow you to convey material with slopes up to 90°. This type of machines is often used with an horizontal/vertical/horizontal configuration.
Reversible Chain Conveyors: Central chain conveyors are also available in a reversible version, which allows you to convey material in both directions.
