How to produce granite setts with all sides split?

Red granite pavers — Maroon Black 10x10x5At the beginning, stone blocks weighing from one to several tons come into production. To cut them into smaller blocks we use large stone hydraulic presses with a force up to 160 tons. Or they are cut with diamond blades of large diameter and water-cooled. It is necessary to have a lot of accompanying equipment: loaders or an overhead crane.

After the large blocks are divided into smaller ones – easily transportable, they are put on relatively small presses with the force of 10 – 40 tons. There the formation of natural split granite setts is made to the size of 10×10 cm and 5 cm thickness, or other sizes. The standard sizes of split stone setts that we produce to stock – are 10 * 10, 5 cm and 10 cm thickness. This is the most popular size, which is easy to install and combines perfectly in other colours granite setts.

How many square meters can we got from one ton natural split granite setts

Dark granite natural setts with sawn sides (Gabbro)So, would you convert ton of split setts to square meters by yourself, and in the end check your supplier, first of all, to start from density of granite. Its standard indicator is 2700 kg / m³, however, Gabbro and Basalt are more heavy stones – their density is 3000 kg / m³. The mass of one stone is 10 * 10 * 10 cm from granite of the “Pokostivske” deposit. So: 0.1m * 0.1m * 0.1m * 2700 kg / m³ = 2.7 kg – the mass of one sett stone.

Further: at install natural split stone setts, the distance between stones is minimum 1 cm. And that means, We can lay out only 9 stones pcs. Then –  1m² is 9 × 9 stones = 81 pcs.

So it turns out: 1m² is 81 stones * 2.7 kg = 219 kg.

Then in 1 ton: 1000/219 = 4.5 m² split light gray cobblestone from “Pokostivske” granite deposit.

Due to the higher density –  Gabbro cobblestones 10 * 10 * 10cm in one ton will be less – about 4 m². More technical information – in table below:

Full loading tuck with gray granite setts of the “Pokostivske” deposit, the size 10 * 10 * 5 cm will consist of approximately 20 big bags.
