In the sand-making industry, the processing of shale often poses a challenge: it is soft and easy to be crushed, but once it comes into contact with water or mud, it immediately turns into a “sludge king”, easily clogging the crusher. When dealing with such materials, many sand factory owners hesitate in choosing the model – should they opt for an impact crusher or a double roller crusher?
Hydraulic Roller Crusher
In fact, the characteristics of shale determine that it is not suitable for “violent impact”, but rather is more suitable for “gentle compression”. Hua Shengming Heavy Industry (HSM) suggests: for processing shale, the fully hydraulic roller crusher is an extremely cost-effective choice. When using traditional impact crushers to process shale, a large amount of ineffective fine powder is produced, and due to the high-speed rotation of the impeller, the viscous shale material is easily adhered to the impeller and the liner, causing frequent shutdowns for cleaning.
However, Hua Shengming’s double roller crusher adopts the “double-roll relative compression” process, which does not pursue high-speed impact, but rather uses the gap to “crack” the shale. This method not only has extremely low energy consumption, but more importantly, combined with our custom high-chrome alloy liner and powerful self-cleaning design, the material is difficult to stay on the liner surface, fundamentally solving the problem of shale sticking causing machine blockage.
The manufacturer particularly reminds: Economic benefits are not only determined by the equipment price, but also by the “operating cost”. When processing shale, the wear parts of the impact crusher consume very quickly and are replaced frequently, while the liner of Hua Shengming’s double roller crusher has a longer service life and a simple structure, making maintenance extremely convenient. If your shale material has a high moisture content, it is recommended to select our matching forced discharge device to ensure that the material is discharged along with the pressure.
If you are still struggling with the model selection, please bring samples to Hua Shengming’s factory for on-site testing. Through the comparison of actual powder production rate and power consumption, we can help you calculate this “economic account”, ensuring that your shale sand-making line not only does not get clogged but also produces high-profit quality products!
