If you want to learn about our products , please call or write mail consultation.

In fact 40% of an average limestone quarries production, results in scalpings. With advances in machinery, quarries are producing less and less scalping waste and any waste they did have is now being re-processed into products such as Type 1 Limestone, by washing down the Scalpings to remove the clay and derive a more valuable product

Effects of Scalping on Direct Shear Strength of Crusher

Effects of Scalping on Direct Shear Strength of Crusher

Sep 09, 2018 Scalping is an essential process for a quarry to produce a series of crusher run products with specific grading specifications for various applications. To study the effects of scalping on the direct shear strength of crusher run, large-scale laboratory direct shear box tests were carried out on crusher run specimens scalped to pass 75, 37.5, 19, 9.5, 4.75, and 2.36 mm

Quarry Scalping When quarrying stone there may be areas in the Quarry where there is a large amount of clay contamination. These occur particularly in Limestone Quarries where the clay sediments collect in fissures in the stone. This clay slows down the Crushing and Screen process, so it is scalped off at a size (generally 80mm – 100mm)
