Product Features
Dual‑shaft counter‑rotating self‑breaking‑arch structure ensures smooth feeding without blockage for wet, caked rock wool ore materials with large particle‑size differences.
High‑efficiency variable‑frequency speed regulation design enables dynamically adjustable feeding flow to adapt to different capacity loads of the production line.
The fully enclosed body effectively prevents dust leakage and meets the environmental dust‑removal requirements of thermal insulation material factories.
The spiral blades are made of wear‑resistant manganese steel and can be strengthened by hardfacing welding to support 24‑hour non‑stop heavy‑duty production.
Dual control modes: on‑site local manual control + remote automatic control via DCS/PLC central control system.
Working principle
The mixed mineral materials in the storage bin fall by gravity into the sealed housing cavity of the feeder and fill the space between the two screw shafts.
The drive motor, paired with a hard‑tooth surface reducer and a precision synchronous transmission mechanism, drives the twin screw shafts to rotate synchronously in opposite directions.
The screw blades push the materials forward for axial conveying. The two shafts shear and agitate each other to actively break up agglomerated mineral materials, eliminate material bridging and suspended voids, and prevent material interruption.
The frequency converter adjusts the motor speed in real time to change the screw feeding volume and achieve stepless adjustable flow. When a loss‑in‑weight weighing module is optionally equipped, closed‑loop feedback control of the flow is formed to further improve the batching metering accuracy.
Materials are discharged evenly and stably from the discharge port and sent to the bucket elevator or cupola charging system.
The control system monitors current, material blockage and material level signals in real time to realize equipment interlock protection and automatic continuous production of the whole line.
Efficient and stable feeding with small fluctuation in discharge flow, stable smelting conditions, and greatly reduced bulk density deviation of finished rock wool products
Wear‑resistant components feature a longer service life, the whole machine has a low failure rate, unplanned downtime is reduced, and the operating efficiency of the entire production line is improved.
It boasts a wide production capacity coverage, compatible with facilities ranging from small pilot production lines to large‑scale high‑speed rock wool production lines, and supports non‑standard customization.
