Whether you’re an aggregate producer or involved in concrete and asphalt recycling, the efficiency and durability of your rock crushing equipment are critical for a successful operation. However, one of the most significant threats to this machinery’s performance is contamination. The unintentional mixing of improperly sized materials can lead to a host of problems, jeopardizing the quality of construction products and causing potential damage to essential machinery like rock crushers and concrete mixers.
This contamination not only affects the stability and strength of the final product but can also place unnecessary strain on the equipment tasked with processing these materials. To maintain optimal performance and avoid costly downtime, it’s essential to pay close attention to preventing contamination during the sorting and processing stages. Let’s dive into the key strategies for keeping your stockpiles clean and your rock crushers running smoothly.
How to Prevent Stockpile Contamination
Many rock crusher operators produce multiple products simultaneously. If the components of your screening process are not correctly aligned, there’s a high risk of 
contamination from mixed product sizes. A common issue occurs when the crusher settings and screen cloths are not properly matched, leading to stockpiles containing materials of incorrect sizes. Ensuring that your crusher settings are correct and choosing the right screen cloths are crucial steps to avoid this.
Choosing the Right Screen Cloth for Desired Products
Your crusher can generate a wide range of product sizes, so it’s vital to install the correct screen cloths for the sizes you want to achieve. Selecting the appropriate screen cloth
ensures you provide high-quality materials that meet customer demands while maximizing your production efficiency. Mellott’s experts are available to help you choose the best screen cloths for achieving the highest tonnage and the best results from your crushing equipment.
Minimizing Dust for Better Performance
Excessive dust during operation can cause several issues, from compromising the health and visibility of your operators to clogging the engine’s air filter and increasing wear on belts and other components. To keep dust under control, a spray bar can help reduce dust by spraying water during crushing operations.
Additionally, ensure the rubber skirting on the discharge conveyor remains snug against the belt to help minimize dust levels in the discharge area.
Troubleshooting and Additional Support
If you encounter other issues with your crusher, Mellott’s service team is always ready to assist with troubleshooting. By mastering the techniques outlined in this guide, you can enhance the efficiency of your rock crushing operations, avoid material contamination, and extend the life of your equipment. As you work towards continuous improvement, implementing these best practices will help reduce downtime and boost productivity.
