Sealed Polyurethane Skirtboard Skirt Rubber for Leak PreventionSkirt Rubber Coal Barrier Belt

Skirt rubber for belt conveyor skirtboard skirt rubber

Skirt rubber is a rubber plate used for sealing between the conveyor belt and the skirtboard, as well as between the buffer bed and the skirtboard. Its design and material selection are crucial to withstand long-term friction and effectively prevent material spillage and dust reduction.

Here are some detailed information about skirt rubber:

Installation Methods

There are two main installation methods for skirt rubber: butterfly nut type and handle type. The installation process involves directly mounting the skirt rubber to the lower edge of the belt conveyor skirtboard, ensuring accurate positioning to guarantee its sealing effect.

Material Selection

The part of the skirt rubber that contacts the belt is typically made of polyurethane blocks due to their strong wear resistance. The polyurethane blocks and rubber plate are bonded using a hot vulcanization process, enabling them to endure prolonged friction without separating from the rubber. Additionally, the rubber of the anti-spill skirtboard is synthetic rubber, which requires the incorporation of heat-resistant, aging-resistant, and damage-resistant additives such as styrene-butadiene rubber in specific proportions to ensure performance.

Usage Characteristics of Skirt Rubber

Skirt rubber is convenient and quick to use, featuring a double-layer seal: the inner layer prevents material spillage, while the outer layer reduces dust. The area in contact with the belt has a composite polyurethane layer, which offers a long service life and does not damage the belt. These characteristics enable skirt rubber to fundamentally resolve issues such as coal spillage, air leakage, and powder escape on both sides of the skirtboard, effectively reducing dust concentration in the belt corridor.

Precautions

When selecting skirt rubber, users should be aware that there are low-quality anti-spill skirtboards on the market, which may be made from reprocessed discarded rubber items. Such skirtboards might melt at slightly elevated temperatures, leading to premature belt failure. Therefore, users should choose reputable manufacturers, request samples for testing, and confirm that the hardness is appropriate and there is no strong odor before making a purchase.
