ABSTRACT:
An applicator for distributing a flowable solid product in the form of pellets or granules includes a hopper assembly which supplies the product to a product distribution gun, both being coupled to a pressurized air source. The hopper assembly includes a hopper having a downwardly and inwardly tapering bottom which terminates at a central cuplike portion. The product passes from the cuplike portion, through a product line and into an air flow path in the gun. The product is pulled into the gun by a venturi arrangement connecting the product line and the gun. Air is injected into the cuplike portion to fluidize the product in the hopper. Baffles in the hopper control the product flow in the hopper. Bell transitions, having a narrowing and widening cross-sectional dimensions, are used to collimate elongate pellets passing between the hopper and the gun.
