To heat the limestone evenly in the kiln, the particle size of feed must be relatively uniform. To avoid long residence time in the kiln, the particle size of limestone must be small, typically about 1 ½”. However, due to the nature of the crushing operation in reality, there is a range in size from ½” to 2”. Since the residence time and

Modified Gravel. 2A Modified Gravel is a mixture of grey, crushed, limestone particles ranging from fines up through roughly 3/4". The spread of particle sizes in the 2A Modified allows it to be very well compacted but limits its ability to be used for drainage. It is useful for driveways or as a base layer for hardscaping projects.
