HL – Hopper loader for powders


The hopper loader series HL is Plantech-CST’s receiver for powdery or dusty bulk materials. This equipment can be used in stand alone or centralized conveying systems both in pressure and vacuum situations. The wide range of sizes allows for conveying from 1Kg/h up to 4000 Kg/h.

The product picked up from a storage device through a suction probe/screw/rotary valve is pneumatically conveyed either via vacuum or pressure by means of a conveying pump. The product is transferred to the HL receivers. During this phase the integrated filters are cleaned through the pulsation of compressed air, when the cycle is completed the product is discharged from a butterfly valve installed on the bottom of the receivers.
