Need an air slide? One that goes around corners? And is simple to install?
Scirocco II hose is an alternative to conventional methods of transporting powder through processing systems such as screw, belt or air slide conveyor systems. The hose operates on a slight decline and utilising the fluidization principle in which a powder material is converted from a static solid-like state to a dynamic fluid-like state when a gas is passed up through the material. Uniquely, the fluidization system of Scirocco hose is vulcanised into the lower wall of the rubber hose. This incorporates air supply ducts from which small openings lead into chambers covered with a breathing cloth membrane. These factors mean that Scirocco hose will contribute to significant savings in overall processing costs.
Due to the innovative design of Scirocco II hose, air flow is equally distributed over the full length of the hose. A precise arithmetic relationship between the inner diameter of the feeder line channel, the choke inlet diameter and the size of the expansion cell means that the entire cross section of the hose may be utilized for transportation. By optimizing fluidization, minimal compressed air is required for maximum transportation and consequentially substantial savings may be made in running costs.
In fact, through a six meter long Scirocco II hose of Ø100mm, 60tph of cement may be transported. In energy terms that equates to the amount of power required to light an eight watt bulb over the same period of time.
Another major advantage of Scirocco II is that due to the flexibility of its rubber structure and its small cross section, the hose is easily installed in and around existing plant and equipment. For instance, the hose may be mounted around a pillar or passed through openings where a straight screw conveyor could not be installed due to its rigid design. Often no equipment is required for installation and the hose may be mounted into place by hand. This reduces upfront engineering and installation costs in new systems and allows retro-fitment even into confined spaces.
In addition, the Scirocco II hose is fully sealed from the environment. This prevents the escape of dust and reduces contamination by moisture, making it weather-proof and also shock-resistant. As there are no moving parts in Scirocco II, and due to low friction causing minimal wear of the hose, virtually no maintenance is required.
Scirocco II is suitable for almost all fine powders that may be fluidized such as cement, magnesium oxide, aluminium oxide, aluminium hydrate, FE-II sulphate, titanium ore, gypsum, micro silica, quartz grain, starch, phosphate, sintering powder, washing powder, lead oxide, fly ash and pulverized limestone. The grain diameters of suitable bulk products generally ranges from 15 to 200 µm, In addition it is also used for fluidised product mixes containing a minimum of 15 percent fines below 20µm with the maximum grain size not exceeding one to two millimetres. Scirocco II is manufactured in lengths of up to ten meters. longer lengths may be formed by joining several hoses with flanges. Diameters range from Ø76 to Ø250mm, the latter being capable of handling up to 350tph of a product like cement.
