The Dense Phase Conveying System is the most reliable; efficient to minimize particularly the problems for handling the wide and adequate range of dry bulk solids up to 200 TPH Capacity at the exceeding terminal distances - 1,200 meters. This system includes weighing, batching, blending, lump breaking, storage, master control equipments etc. through Dense Phase Conveying System for bulk material handling in the plant.
Dense Phase System is applicable to push the highly dense concentration of bulk solids effectively at a low constant speed inside the conveying pipe lines. Any type of material (heavy, abrasive or, fragile, crystalline or granular) can be conveyed without causing the degradation due to low velocity and less wear to the system components. This type of conveying is reliable, flexible and maintenance free due to lower quantum of moving parts and it can be easily installed at places where space availability is very less specially for installing conventional conveying systems.
The limited volume of air is utilized at the transporting vessel to move the material into the line at maximum density while the balance air quantity is added along the conveying line through coupling unit provided at starting on the pipeline to overcome the pipeline frictional losses thus pumping material at the highest obtainable efficiency. The Coupling Unit ensures a uniform gradient and helps to maintain the material at maximum density. It also helps in maintaining the desired velocity, and over coming the pipeline / bend''s friction and helps to restart the flow of blocked material if any along the conveying line regardless of length .These coupling Unit also helps in minimizing the compressed air consumption and pipe abrasion.
The plugging problem is prevented by improving the ratio of the material to air throughout the system to convey the material at the highest obtainable efficiency and degree of reliability, the highly abrasive materials can be conveniently conveyed at lowest possible velocities consuming nominal quantity of air with the help of these systems. The highly flexible check valve provided with Coupling Unit fittings are very responsive to any back feeding due to changes in conveying line pressure thereby allowing throttling of the air supply pressure and volume automatically. The designing of the system depends upon the properties of the material like convey ability, moisture contents, product degradation, bulk densities etc.
In addition to the above, the system has the following features also:
The material inlet valve provided with the system has a special inflatable rubber seal which is being inflated with the help of air pressure on closure of the inlet valve thus eliminating any chance of air leakage from the transporter top ensuring a 100% sealing at the vessel inlet.
