Solex Thermal Science has decades of experience in designing proven discharge feeders that achieve desired flow behaviours. Our world-tested solutions are fabricated in house and tailored to different material flow properties, while providing operators with maximum control and a guaranteed first-in-first-out flow sequence.
Discharge feeders regulate the solids product discharge and rates to ensure uniform drawdown mass flow and that the product is inside the heat exchangers for the required residence time. They also ensure gentle handling of the product throughout the process.
Solex feeders are selected based on the product characteristics and the process conditions.
Now available at Solex!
Solex discharge feeders are now also offered as standalone devices for all your bulk solids handling needs. Read the full news release here.
Our skillful design approach blends practical, scientific and experience-based considerations to offer a fully integrated solution that includes transitions from existing equipment, vessel or silo, and interfaces with downstream conveying equipment.
Our rich reference list and years of experience in this field makes Solex the ideal partner when looking for the right discharge device.
Below are some of our typical standalone devices:
Best suited for lighter material applications such as sand, sugar or plastics — free-flowing granules and non-cohesive powders that cannot easily fluidize. Solex’s vibratory discharge uses a series of partially overlapping louvers carefully positioned within a self-supported frame that vibrates linearly to offer a full live-bottom system. The system is designed to ensure mass flow by allowing product to flow along the multiple overlapping shallow louvers into a series of slot openings.
Best suited for medium-duty applications such as seeds, beans or delicate granules — typically low flow rates The sliding frame feeder is formed of two parts: one fixed and another that slides in a linear motion. The fixed part is made up of small hoppers that guide the product toward the ladder-shaped sliding part that, due to its horizontal back and forth movement, sweeps product from the hoppers to a series of discharge chutes. The ladder is powered by an pneumatic actuator that provides control of both the speed and amplitude of the oscillations. The sliding frame feeder is advantageous when there are height limitations.
Best suited for heavy-duty applications such as minerals, fertilizer and other high-density granular solids. In Solex’s oscillating gate, the product splits into the two symmetrical mass flow funnels, created by the fixed outer walls and the moving inner walls at the centre that form a pair of slotted shaped openings that the material flows through. An actuator-positioner regulates the width of the openings for feed rate control.
This is a static type of discharge device, with the bulk solids flowing in an inverted cone that is either connected directly to a feeding device (e.g. rotary valve) or sits above a conveying device (e.g. pan feeder or drag conveyor) with a specified gap between the bottom of the cone and the conveyor. The cone is typically used when the bulk solids are fully free flowing. The cone can also be used in conjunction with other discharge devices (e.g. rotary valves) when handling bulk solids that may fluidize.
Depending on the application, Solex also provides the following alternatives:
- Oscillating Beam Feeder
- Mass Flow Screw
- Circle Feeder
- Rotary Valve or Rotary Vane
- Pan Feeder
