Polyurethane Coal Guard Skirt for Sealing and Preventing Material Leakage on Both Sides of the Guide Chute

Side rubber belt conveyor side rubber guide chute side rubber

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

Here are some detailed information about side rubber:

Installation Methods

There are two main installation methods for side rubber: butterfly nut type and handle type. The installation process involves directly mounting the side rubber on the lower edge of the belt conveyor guide chute. This process requires ensuring the accurate positioning of the side rubber to guarantee its sealing effect.

Material Selection

The part of the side 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 withstand prolonged friction without separating. Additionally, the rubber used in the anti-spill skirt 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 Side Rubber

Side 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 side rubber to fundamentally resolve issues such as coal spillage, air leakage, and powder escape on both sides of the guide chute, effectively reducing dust concentration in the belt corridor.

Precautions

When selecting side rubber, users should be aware that there are low-quality anti-spill skirts on the market, which may be made from reprocessed waste rubber products. Such anti-spill skirts may melt at slightly elevated temperatures, leading to premature belt failure. Therefore, users should choose reputable manufacturers when purchasing side rubber and request samples for testing to confirm moderate hardness and absence of strong odors before making a purchase.
