TEKPRO Dec Group lej zasysający1 Standard Suction Hopper
The hopper is designed with a special discharge angle allowing full emptying of the equipment. The size is adapted on one side to the equipment to be discharged and on the other side to the required PTS model. The standard hopper is equipped with a fluidization filter allowing an optimal control of the powder flow.

2 LB Hopper
The LB Hopper, in combination with the PTS System, is the ideal solution for evacuating lumpy or compacted powder without changing its characteristics. It is equipped with a tool whichbreaks bridges and lumps to provide a constant powder flow. The system with its limited height is easily installed directly at the outlet of existing equipments such as dryers etc. with limited head space.

3 Fluidization Hopper
The hopper is equipped with a fluidization cone constructed of a special porous material. The product flow of sticky or non freeflowing powders is optimized by compressed gas which flows through the pores of the cone. Inert gas can be used in case of flammable products.

4 Fluidization Hopper with lump breaker
In case of lumpy and bridging products, a combination of a fluidization cone and a lump breaker can be supplied. With this combination nearly any product can be handled efficiently
