Business & Technology TechSurveillance

The rock crushing process begins with a primary crusher that breaks down large, two to three feet diam-eter rock into rocks six to eight inches in diame-ter. A secondary crusher can then break it up into pieces about one-quarter as large. Charleston Stone also has tertiary crushers that turn smaller rock into gravel, sand, or lime. This rock crush-

Nov 01, 2006 The influence of particle size on wear rate in compressive crushing of rock was investigated experimentally. A test apparatus was developed to replicate the squeezing wear that is present in many rock crushers. Silica sand of different size classes between 0.725 and 2.03 mm was used. The crushing load was varied.

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

The cost to install gravel is $1.25 and $1.80 per square foot. The average cost of a 16x38 foot gravel driveway is $1,500. Driveways on the smaller side can cost as little as $300 with a larger and longer driveway costing as much as $60,000. Whether you want a basic gravel driveway or something more stylish, multiple factors affect the cost.

Aggregate Crushing Value Test - Procedure And Result
