In a crushing production line, using a herringbone conveyor belt (a conveyor belt with a herringbone pattern on its surface) offers several targeted advantages over ordinary flat conveyor belts, especially adapting to the material characteristics and working conditions of the crushing scenario. The specific advantages are as follows:
1. Enhancing Material Anti – Slip Ability, Reducing Slippage and Rolling
- Core Advantage: The herringbone pattern (with a cross – section in the shape of “∧” or “∨”) can increase the friction between the surface of the conveyor belt and the materials. Especially for bulk and granular materials after crushing (such as ores, gravel, construction waste, etc.), it can effectively prevent the materials from slipping, sliding down or rolling due to the inclination angle, vibration or inertia during start – up and shutdown in the conveying process.
- Applicable Scenario: In a crushing production line, conveyors often need to be arranged at an incline (to lift the height of materials). The herringbone pattern can significantly improve the “material – grabbing” ability of the conveyor belt, allowing a larger conveying angle (usually up to 18° – 25°, far exceeding the 12° – 15° of flat conveyor belts), thus reducing the floor area of the equipment.
2. Guiding Materials to Convey Centrally, Avoiding Deviation and Accumulation
- The symmetrical structure of the herringbone pattern (for example, the vertex of the “herringbone” faces the center line of the conveyor belt) can form lateral constraintson the materials, naturally guiding them to gather towards the middle of the conveyor belt during conveying and reducing the problem of conveyor belt deviation caused by the materials shifting to the edge.
- At the same time, it can prevent materials from accumulating at the edge and jamming the equipment (such as rollers, racks), reducing the probability of equipment wear and failure, and is especially suitable for materials with irregular shapes after crushing.
3. Enhancing Wear Resistance and Durability, Adapting to Harsh Working Conditions
- Materials in the crushing production line (such as ores, concrete blocks) are often of high hardness and sharp edges, causing severe wear to the surface of the conveyor belt. Herringbone conveyor belts usually adopt high – wear – resistant rubber materials(such as a composite of natural rubber and styrene – butadiene rubber). The pattern part is thicker, and its tear resistance and wear resistance are better than those of ordinary flat conveyor belts, resulting in a longer service life.
- The gaps between the patterns can reduce the continuous extrusion of materials on the surface of the conveyor belt, lowering the risk of local wear, and is especially suitable for conveying materials containing sharp particles.
4. Optimizing Material Conveying Efficiency, Reducing Residues and Cleaning Costs
- The concave – convex structure of the herringbone pattern can reduce the contact area between the materials and the conveyor belt, lowering the probability of adhesion of viscous materials (such as wet clay, slag) and reducing material residues after the end of conveying.
- For crushed materials that are wet or contain moisture (such as ores operated after rain), the gaps in the pattern can drain water and mud, preventing the materials from sticking to the conveyor belt due to humidity, ensuring the continuity of conveying and reducing manual cleaning costs.
5. Adapting to Complex Working Conditions, Improving Production Safety
- A crushing production line is often accompanied by harsh conditions such as dust, vibration and impact. The pattern structure of the herringbone conveyor belt can buffer the impact force when materials fall (such as the moment when materials fall from the outlet of the crusher to the conveyor belt), reducing direct impact damage to the conveyor belt.
- At the same time, materials are not easy to roll off, which can reduce the hidden dangers of equipment jamming and personal safety (such as being hit, tripped) caused by falling materials, improving the overall safety of the production line.
Summary
Herringbone conveyor belts, with their characteristics of anti – slip, anti – deviation, wear resistance and residue reduction, perfectly adapt to the conveying needs of bulk, granular, high – hardness and dusty materials in the crushing production line. They can improve conveying efficiency, reduce equipment loss and lower maintenance costs, making them the preferred choice for conveyors in crushing scenarios. However, their cost is slightly higher than that of flat conveyor belts, and the patterns are prone to dirt accumulation (regular cleaning is required). It is necessary to select the appropriate pattern depth and angle according to the specific material characteristics (such as particle size, humidity, hardness).
