Diamond Lime operates its own active limestone and calcium carbonate mines, which lets us manage the supply chain from the source. Cutting out intermediaries means we can deliver raw material at a defined purity, a stable price and a guaranteed tonnage.

• Direct extraction from mines under our own management
• Limestone supplied in a range of purity grades to suit each industry
• Long-term contracts with agreed tonnage and delivery schedule
• Chemical analysis of the deposit provided before any contract is signed

Our crushing plant is built around a Parker jaw crusher rated at 250 tonnes per hour, engineered to process limestone and mineral feed at maximum throughput with consistent reliability.

• Parker jaw crusher with a capacity of 250 tonnes per hour
• Precise grading from lump size down to fine mesh, to customer specification
• Multi-deck screens for a uniform, well-separated product
• Continuous monitoring of output mesh throughout production

In our micronizing unit, calcium carbonate and lime are milled and classified to high mesh values. Consistency of particle size distribution is the key metric we monitor continuously here.

• Micronized powder produced across a range of mesh sizes
• Air classifier for a uniform particle size distribution
• Brightness and purity preserved throughout the process
• Suited to the paint, plastics, rubber, paper and construction industries

Limestone is converted into quicklime (CaO) in our calcination kilns, and the hydration unit produces hydrated lime (Ca(OH)₂) at a controlled moisture level. Firing temperature is what ultimately determines the reactivity of the finished lime.

• Calcined (quick) lime produced at a controlled CaO content
• Hydrated lime with standardised particle size and moisture
• Kiln temperature monitored to avoid under-burning and over-burning
• Available as lump, graded and micronized product

Product is packed to match how you store and feed it into your line — from 25 kg sacks through one-tonne jumbo bags to bulk dispatch.

• 25 kg sacks with a moisture-barrier layer
• Jumbo bags (FIBC) in a range of capacities
• Your brand and technical specification printed on the packaging
• Palletising and stretch-wrapping for safe transport

High-tonnage loading capacity is one of the main reasons our commercial partners keep coming back. Delivery is handled nationwide with heavy fleet and a fixed dispatch schedule.

• Bulk loading by tipper, trailer and bulk tanker
• Nationwide delivery through our contracted fleet
• Dispatch planned around your production calendar
• Weighbridge tickets and shipping documents with every consignment

Every consignment is checked for chemical composition and grading before it leaves us. Strict adherence to technical analysis is what keeps quality consistent across repeat deliveries.

• Chemical analysis (CaO, MgO, SiO₂, LOI and more)
• Grading tests and output mesh control
• Brightness, moisture and lime reactivity measured
• An analysis certificate issued with every consignment
