T-Type Anti-Spilling Skirtboard and Coal Retaining Seal

The anti-spilling skirtboard is an automatic self-adjusting conveyor skirt sealing system designed to prevent spillage and leakage. The Y-type anti-spilling skirtboard consists of a primary seal and a secondary seal, forming a dual sealing mechanism. It is soft, wear-resistant, and conforms tightly to the belt through the elasticity of the sealing strip itself. The multi-layer protection of the primary and secondary seals collects dust to achieve spill prevention.

The anti-spilling skirtboard adopts an integrated structure with a straight plate and T-type foot or a Y-type structure, and can also be custom-produced according to customer requirements. The straight plate height is 250mm (or processed according to actual dimensions), with a thickness of no less than 20mm, adjustable as per customer needs. The T-type foot width is not less than 50mm (adjustable based on customer requirements).

The anti-spilling skirtboard for chutes produced by our company is optimally designed based on the operational characteristics of the belt and the structure of the chute, incorporating the advantages of various types of anti-spilling skirtboards from both domestic and international sources;

1. The inclined surface of the vertical plate matches the angle of the buffer idler, featuring a double-layer seal for effective sealing performance:

2. Made entirely of polyurethane material, it has a long service life and does not damage the belt;

3. The side seal can be adjusted according to the distance between the belt edge and the chute. The high-quality side seal combines well with the belt, preventing the side plate from being cut;

4. The sealing groove of the side seal adopts a single-sided arc transition, which prevents the side seal from being cut when the belt deviates and allows it to automatically return to its original state;

5. The clamping device can self-adjust the pressure on both sides of the angle steel, ensuring even pressure and preventing the side seal from falling off;

6. Easy and simple installation and adjustment.

Some coal mining units use worn-out belts as a substitute for anti-spilling skirtboards to seal chutes, which can save production costs. However, worn-out belts do not conform well, are not wear-resistant, and offer poor sealing performance.

Users can freely cut the anti-spilling skirtboard to length based on their needs. The width generally ranges from 150-350mm, with a thickness of 15mm. Other specifications can be custom-made as required. The anti-spilling skirtboard is fixed using specialized clamps. Each meter of anti-spilling skirtboard is equipped with one meter of angle aluminum and two clamps.

Advantages of the Chute Anti-Spilling Skirtboard:

1.It uses a multi-guard triple sealing strip for sealing, which improves performance compared to ordinary single-piece rubber anti-spilling skirts by a factor of 2. It provides an additional sealing space compared to dual-seal anti-spilling skirts, enhancing effectiveness.

2.The main body of the anti-spilling skirtboard—chute anti-spilling skirtboard—is black, made from high-quality imported natural rubber and styrene-butadiene rubber through mixing. It maintains stiffness while increasing elasticity, allowing the green multi-guard sealing strip to adhere closely to the conveyor belt. Even after the multi-guard system reaches the end of its service life, it can continue to perform the duties of an anti-spilling skirtboard, protecting the user's belt from damage.
