Skirt Rubber for Belt Conveyors and Chute Sealing

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

Here are some detailed pieces of 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 chute, ensuring accurate positioning to guarantee its sealing effectiveness.

Material Selection

The part of the skirt rubber that contacts the belt is typically made of polyurethane blocks due to their excellent wear resistance. The polyurethane blocks and rubber plate are bonded using a hot vulcanization process, enabling them to endure prolonged friction without separating. Additionally, the rubber used in the skirt is synthetic rubber, which requires the incorporation of heat-resistant, aging-resistant, and damage-resistant additives such as styrene-butadiene rubber 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 chute, effectively reducing dust concentration in the belt corridor.

Precautions

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