Onyx Quarry Hydro-Bags

Hydro Bags are expanding steel cushions whose technological brilliance lies in their basic ability to move slabs or blocks of up to 1000 tons or more without the need to prepare slots to house the jacks.
Hydro Bags have a thickness of just 2mm and can easily be slipped into the diamond wire saw cut.
They consists of two sheets of high tensile steel welded together using the latest laser techniques.
Water is hydraulically pumped in at a pressure of 30-40 bar expanding them up to 25-30 cm resulting in a thrust force of up to 1000 tons.
By coupling two or more cushions side by side or combined together in packs it is possible to obtain greater displacement.
It must be pointed out that our Hydro Bags only use running water as an expansion fluid and not oil as with other hydraulic systems. It is for this reason that Hydro Bags are classified as environmentally friendly.
NB! Hydro Bags don’t require any maintenance for the simple reason that they are only used once.
To summarise, Hydro Bags are a simple, versatile and economical tool that have revolutionised the moving of quarry slabs.
All this means savings from the following:
Elimination of the time necessary for the preparation of the slots for jacks
The blocks of stone are obtained with their sections intact
Total elimination of explosives which can potentially damage the product
Partial or total elimination of hydraulic jacks
Less noise and dust caused by the presence of pneumatic hammers
Respect for the local environment
Increased safety for the operators
Limited maintenance

Hydrobag is a pump for filling cushion with water, for borrow material excavation.

Nowadays, most mining and quarrying industries utilize a diamond wire saw machine for bench cutting operations. This method uses a metal wire or cable assembled by diamond beads to cut the hard stone into large blocks. Many parameters classied into controllable and uncontrollable parameters aect the performance of the diamond wire saw cutting meth-od. The uncontrollable parameters are related to rock engineering properties, and controllable parameters are related to operational aspects and machine performance. The diamond wire sawing process’s production rate is one of the most critical parameters inuencing the design optimization and quarrying cost estimation. The cutting rate and wear rate of diamond beads are the most important factors to evaluate quarries’ production performance. This study aims to deter-mine the eects of dierent controllable and uncontrollable parameters on dierent quarries’ production rates. Rock engineering properties like strength, hardness, and abrasivity, and operational aspects, such as cutting angle and drive wheel diameters, are considered as the main factors aecting the production performance of the diamond wire saw method. To discover the inuence of these parameters, a detailed investigation in ten quarry operations was carried out. The relation between cutting rate and diamond bead wear with dierent parameters is estimated. It was observed that dierent controllable and uncontrollable parameters could increase or decrease the cutting rate and diamond bead wear-ing. Furthermore, using simple and multiple regression analysis, performa
