The storage hopper is ideal for discharging smaller quantities of product delivered in 50 lb bags, such as lime, soda ash, sand, cement, or powdered activated carbon (PAC). The unit features an arch-breaking spindle with flexible blades that rotate within the hopper’s bottom cone, preventing bridging and blockage.
The hoppers are custom-fabricated in sack-tip, buffer, and loss-in-weight models, and can be equipped with one or several volumetric screw feeders (rigid or flexible). The rotating mechanism ensures a total discharge and an accurate dosing of the powder. The units can also be furnished with a dust filter, level sensor, mechanical arch breaker, load cells, and a protection grid.
The hopper designs include standard and custom sizes
Hopper capacity ranges from 12 gal to 1,500 gal, and fabrication material can vary depending on the customer’s needs. Typical fabrication materials include High-density polyethylene (HDPE), stainless steel and fiber glass.
