A Micro Feeder is a device engineered to dispense small, controlled amounts of bulk materials such as powders, grains, and granules. These feeders are indispensable in applications requiring ultra-low dosing, typically ranging from a few milligrams to several grams per hour. Whether it’s dosing precise amounts of ingredients in food production or maintaining strict quality control in pharmaceutical applications, micro screw feeders play a crucial role in ensuring efficiency and product integrity. Their ability to deliver accurate and consistent dosing makes them essential in various industries where even the slightest deviation in material quantity can impact the final product’s quality and performance.


Like larger screw feeders, Micro feeders operate on the principle of an Archimedes screw, also known as an auger screw, a helical mechanism that can effectively regulate the flow of various materials, regardless of their diverse flow characteristics. The Auger screw operates within a specially designed hopper with angled walls that facilitate gravity-driven material flow. At the base of the hopper is a trough where the auger is housed. The auger is powered by a specialist stepper motor or servo motor, causing it to rotate. The benefit of using these types of motors is that our micro feeder can achieve exceedingly low feed rates as rotational speeds under one per minute can be achieved. As the auger turns, the material falls into the pockets formed by the screw flights and the hopper trough. the auger screw pushes the material along the length of the trough with every revolution, and the pocket of bulk solid advances by a distance proportional to the screw’s pitch. The rotational speed of the screw’s rotation can be adjusted to control the rate at which material is dispensed over time, while the diameter of the screw directly influences the flow rate, with larger diameters producing higher flow rates. 

An additional agitator is implemented for materials that are cohesive or prone to clumping. The micro feeder’s agitator is driven by an independent motor to avoid over-agitation, which can negatively impact product characteristics. Independently driven agitators provide superior control with variable speeds and adjustable timing, minimising excessive agitation and ensuring optimal material handling.
