W1200F Garland Roller Garland Conveyor Rollers with Handles

Product Introduction:

The garland rollers of the milling machine's feeding system are made of high-chromium alloy rollers with a polyurethane coating. The middle roller bears the weight vertically, and the oblique rollers on both sides form a 135° groove angle to enhance material guidance. The overall bracket is a laser-cut steel plate welded structure with a built-in labyrinth-type sealed bearing unit to effectively block the intrusion of milling material dust. Dynamic balancing adjustment technology ensures that the vibration amplitude is controllable during high-speed operation, and the spiral groove design on the roller surface has both self-cleaning and anti-skid functions. The heavy-duty spring buffer mechanism can absorb the impact of material drop, the special anti-corrosion coating adapts to the high-temperature steam environment of asphalt, and the modular quick-release structure supports the independent replacement of a single roller, significantly reducing maintenance downtime.

What are the specific advantages of polyurethane coating over traditional rubber?

Polyurethane coatings offer higher wear resistance and tear resistance, effectively protecting against sharp edges and corners in aggregates used in milling. Their molecular structure imparts excellent oil resistance and aging resistance, making them suitable for the high-temperature, corrosive environment of asphalt mixtures. The elastic modulus achieved through a specialized microcellular foaming process cushions material impact, while the surface grooves provide both anti-sticking and noise reduction. The vulcanized bond strength with the metal roller is over three times that of traditional rubber, significantly extending service life under high-frequency vibration conditions.

How do triple rollers handle the impact of off-center loads during milling machine operation?

Using a three-point suspension support structure, the central load-bearing roller and the two guide rollers form a dynamic force-balancing system. When material accumulation compresses one side, a spring-loaded buffer mechanism adaptively adjusts the roller tilt to ensure even load distribution. The rollers utilize double-layer ball bearings with a nylon cage, allowing for ±5° of deflection compensation. The rubber shock-absorbing pad at the bottom of the bracket can absorb more than 70% of the vertical impact energy, and the laser-calibrated concentricity ensures smooth rotation under eccentric load conditions to prevent the belt from deviating.
