Dense phase pneumatic conveying allows for the transfer of product in batches with high design capacities and large distances. The product is propelled by the launching thruster – PED-certified up to 5 bar – and proceeds in steps along the entire length of the pipe, at high pressure but low speed, so as to reduce wear on the line and preserve the quality of the product from breakage or demixing.<\/p>

The conical bottom of the sender is designed to feed the product into the line and to fully discharge it. Furthermore, being fed by the system air in batches, its actual air and energy consumption is very low, making pneumatic conveying one of the most efficient modes.<\/p>

Depending on the characteristics of the system and the product to be conveyed, dense phase conveying can take the form of:<\/p>

– <\/span>Single point injection<\/b>: only enough air is introduced into the thruster for conveying the product from the start to the end point. This results in a high pressure in the pipe, capable of conveying the product along the entire length of the pipe to the discharge point.<\/span><\/p>

– <\/span>Full line<\/b>: the air supplied to the thruster is enough to introduce the product at the beginning of the conveyor line. Conveying is ensured by air assists within the line, which inject sufficient air to get the product to the next air assist. This mode allows you to adjust the speed of the product and have it arrive at its destination at low speed

The closed pipes of the pneumatic conveying system, together with the necessary dust collection devices that are placed on arrival, eliminate the dispersion of the product into the environment, helping to keep the workplace clean and safe for the benefit of the operators’ health.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t
