Cascade Bulk Material Loading Chute
Bulk material loading of ships and stockpiles
All other dry bulk loading systems allow material to free fall and in doing so pull volumes of air down with the falling material. This air needs to escape at the base of the chute and when doing so it carries the separated material particles causing highly visible dust emissions.
Unlike freefall chutes the Cascade chute gently supports the material being loaded all the way down the vertical length of the chute and in doing so maintains a constant and low velocity, which together with the cone shape keeps the material in mass flow form. The low velocity causes the material not to pull air down with it and therefore if there is no air to escape there is no dust.
A simpler analogy is to take a cup of flour and hold it with an out stretched arm and then tip it out down on to the floor below - flour dust would be everywhere. Now take the same cup filled with flour and hold the rim 1mm above the floor and then tip the cup - the result would be a small pile of flour and no dust.
So successful is the Cascade principle that dust extraction systems are not required and Cleveland are the only company in the world who actually guarantee dust emission levels of less than 5mg/m3
The Cascade system also carries the benefit of reduced degradation of material as the low velocity material constantly flows on to material within the chute and therefore reduces degradation and impact abrasion
Cleveland Cascades Limited guarantee the throughput, dust emission, degradation performance and liner wear with any chute supplied in a way that can be easily measured or demonstrated to the customer.
Cleveland Cascades are the largest privately owned bulk loading system manufacturer in the world and the owner Ian Barnard is an inventor and enthusiast of the Cascade loading system.
