have always been associated with process industries as well as power
industry world over....so have material build-up problems where storage
bins, silos etc. are employed in the plants.
Power and Cement industries are the two critical core sectors in any national economy. In fact these industries hold the key for development of a country. These industries employ elaborate Material Handling Systems which have bulk storage bunkers, silos, bins, chutes etc. as a part of transportation of fuel/raw material from one part of the plant to the other. Smooth movement of the material such as coal from the storage area upto the crushing equipment is a very important factor in determining the availability of the plant as well as its plant load factor. The material handled e.g. coal has to pass through various system components such as Bunker, Transfer Chutes etc. and this material movement through intricate route poses great operation and maintenance problems. This causes various types of problems mentioned above. Particularly, in the rainy season, when the moisture content in the coal is very high, the problem is compounded.
This is How it Works
The basic principle of MM Air Blasters operation envisages introduction of compressed air at a velocity which kinetically activates dust particles clinging to any surface, with this energy making them vibrate and break free from other particles and surface to which they had adhered.
The compressed air is stored in an air receiver which maintains the air pressure at 6 to 7 kgf/sq. cm. This compressed air is fed to the point of discharge through a 100mm. opening through operation of pneumatically controlled valves. The sudden but controlled release of compressed air into the stored material is at a rate faster than the material can absorb it, thereby causing the material to get dislodged and move. The controlled release of air ensures that the reaction is not transmitted to the support structure and also there is minimal effect of noise or vibration. The actuation of the blaster can be effected either manually or through Electronic Sequence Timer.
One cycle of filling and release is
described as follows:
The MM Air Blasters offer several advantages coupled with diversity of their use or various industries which assume importance in view of greater necessity of uninterrupted plant operation.
MM Air Blasters provide an efficient and effective engineering solution to all materials/deposits/dust build-up problems as well as flow-related problems, and enhance plant efficiency in any industry in which they are suitably used.
