Gravity dosing by batch

 
Silos de almacenamiento, dosificación gravimétrica por batch

This dosing method is used when there is a need for dosing a certain amount of product, after previously establishing a composition.   
When we are weighing the quantity of product that falls into a hopper with load detectors, we are talking about additive dosing.

When we are weighing the quantity of product that is extracted from a hopper with load detectors, we are talking about subtractive dosing.

Additive dosing requires that the hopper scale is capable of being rapidly and efficiently emptied; that is to say it has to be quick emptying the product and remaining clean.  “The key to good dosing is in the discharge"

According to the application and characteristics of the product, we have developed our own range of scale hoppers:

 

HOPPER FAST-D:
Double chamber hopper, fitted with injectors for rapid extraction. Used for dosing difficult products, using pneumatic transport.  (lampblack, Crete, titanium dioxide...).

HOPPER FAST-R:
Rubber hopper fitted with a sequential massaging system for quick extraction.  Used for dosing made by product dropping into the hopper.

HOPPER FAST-T:
Varnished lightweight fabric hopper, especially for minority products that require precision dosing and very quick discharge.

HOPPER FAST-A:
Stainless steel hopper, fitted with air injectors and fluidising panels for quick extraction of abrasive products.  

DOSI-DISH:
Easily regulated plate dosifier.  This element is adequate for adding to a basic hopper for very delicate products so the pellets or grains do not break.
