Working principle
# Variable Frequency Flexible Feeding
Segmented spring rubber pressing rollers clamp and convey boards section by section, with variable frequency control over feeding speed. Low-pressure flexible clamping prevents soft rock wool from collapsing under extrusion as well as edge chipping and uneven board ends, allowing boards to move smoothly and uniformly into the sanding station.
# CNC Precision Thickness Setting & Positioning
Input the target board thickness via the human-machine interface; servo-driven sanding frames automatically lift, lower and lock the sanding gap with real-time closed-loop fine-tuning to fix the cutting depth, ensuring consistent thickness across the entire batch of boards.
# Two-Stage Cross Fine Sanding
The coarse sanding unit quickly levels height differences on board surfaces, while the fine sanding unit delivers delicate polishing. Sanding belts are equipped with left-right reciprocating swing mechanisms for cross sanding that eliminates blind sanding zones, resulting in smooth and refined board surfaces.
# Intelligent Anti-Deviation Correction for Sanding Belts
High-precision photoelectric sensors monitor sanding belt positions in real time, and dust blowing devices stop sensor probes from malfunctioning due to dust buildup. Pneumatic mechanisms instantly and automatically correct any belt deviation to avoid belt tearing and uneven sanding.
# Synchronous Negative Pressure Dust Removal
The sanding zone adopts a fully enclosed chamber. A high-power dust extraction fan continuously generates negative pressure to suck rock wool dust and fibers, capturing dust generated during sanding immediately without fiber leakage.
# Continuous Finished Board Discharge
High-precision rock wool boards after sanding are automatically discharged. The equipment can be connected to cross-cutting machines, film laminators and automatic stacking machines to achieve uninterrupted continuous precision processing on production lines.
Product Features
Flexible grinding without damaging base materials
Lightweight floating sand roller plus segmented low-pressure pressing structure prevents the internal fibers of rock wool from being compacted during grinding, fully retaining its thermal insulation, fire resistance and sound absorption properties.
01
Integrated Coarse and Fine Composite Polishing
A single unit integrates two processes: coarse grinding and fine polishing. The plates can be leveled and polished in one pass without secondary rework.
02
Wide adaptability with variable frequency stepless speed regulation
The feeding speed is adjustable from 7 to 36 meters per minute, compatible with various boards such as low-density soft cotton and high-density hard curtain wall rock wool.
03
Multiple Intelligent Safety Protection
Automatic shutdown and alarm for belt breakage, insufficient air pressure, motor overload, phase loss and electric leakage; the sand roller lifts automatically upon power failure to prevent board damage.

Main shaft of the rock wool centrifuge
The main shaft of the rock wool centrifuge is the core transmission component in the centrifugal fiber-forming process of rock wool production lines. As a key hub connecting the power source and the fiber-forming spinning wheel, it directly determines the forming quality of rock wool fibers, the operational stability of the production line, and production efficiency. It is widely used in various production lines for inorganic fiber thermal insulation materials such as rock wool, mineral wool, and glass wool.
On-site installation: Application scenarios
Specialized manufacturers of export rock wool panels provide customized products for overseas orders, including curtain wall rock wool, exterior wall insulation rock wool, and fire-resistant high-density rock wool, all precision-engineered to meet stringent dimensional accuracy requirements of international clients.
In color-coated rock wool sandwich panel manufacturing plants, the rock wool core material undergoes double-sided high-precision leveling to enhance adhesion density with color steel plates, reduce voids and delamination in the finished panels, and improve overall panel quality.
In the deep-processing workshop for exterior wall insulation panels, after grinding and cutting, the panel surfaces are eliminated of burrs, loose fibers, and unevenness to ensure optimal adhesion between the exterior wall insulation mortar and finishing materials.
