Abstract

A venturi device is used in a pneumatic conveying system. The device comprises a housing having a material feed inlet through the housing, and open downstream end through which the material is carried away from the housing, an open upstream end fitted with a frustoconical nozzle through which primary air is fed to produce a vacuum in the device and an air inlet through which secondary air is drawn by the vacuum. The air inlet is adjustable in size to accommodate different air to material mixture ratios within the device.
