Powder Handling

Dilute-phase conveying

Dilute phase systems operate above or under atmospheric pressure and are used to convey bulk materials from single or multiple intakes.

Pressure conveying systems

Vacuum dilute phase systems operate in a vacuum under atmospheric pressure. This system is generally used for conveying bulk material from multiple intakes through a pipeline to an individual destination. Here the powder is separated from the air through a vacuum filter.

Through an intake, the powder is dosed into the airflow and transported in a continuous flow at a relatively high velocity through the pipeline to the dedicated destination. The vacuum pump includes a pressure transmitter to protect the powder to air ratio in order to avoid blockage.

Unlike the pressure conveying system, the vacuum system easily picks up bulk material from the intake and does not heat up the product. The vacuum system has superior leak containment and is often used where there is a demand for cleanliness and ATEX considerations.

Vacuum conveying systems

Positive pressure dilute phase systems operate above atmospheric pressure. This system is used to convey bulk materials from single or multiple intakes through a pipeline to one or more destinations. Here the powder is separated from the air through a filter.

Through an airlock, the powder is dosed into the airflow and transported in a continuous flow (at a relatively high velocity) through the pipeline to the dedicated destination. The blower pump is equipped with a pressure transmitter to protect the powder to air ratio in order to avoid blockage in the pipeline.

Pressure systems typically have a higher capacity and can convey product over further distance than a vacuum system.

Daniatech pressure airlock hopper is equipped with air leakage venting, level sensor and service manway. The Daniatech airlock ensures a gentle product flow.
