^{Portable / Stationary}

^{Air Lubricators provide lubrication for most general air preparation applications in a pneumatic system. Gemsa Air Lubricators provide optimum and uniform lubrication with fine adjustment, including those with simple piping arrangements.

It is extremely important that an adequate supply of the correct type of rock drill oil is constantly fed to the hammer while it is operating. Failure to do so will quickly lead to excessive component wear and if the oil supply is cut off for any reason, the piston will quickly seize inside the wear sleeve, resulting in irreparable damage to both components. An air line lubrication system should be installed, preferably on the drill rig.}

Product Solutions

* Gemsa Air Lubricators capacity from 5 lt to 150 lt .

Expert Engineering

Our air line lubricator tanks , pressure vessels tested and certificated.

^{Drilling Application- DTH}

^{The lubricator reservoir should be of sufficient capacity to supply the required volume of rock drill oil for a full shift.
It is equally important that the lubricator system must be adjustable and have a visual check to ensure the lubricator does not run out of oil. Gemsa design air lubricators according to above needs and specifications. Also as a good general guide, Bulroc hammers require a third of a point of oil per 100 cfm of air through the hammer (0.07 liter per meter cubed). The amount of lubrication oil should be increased by 50% when drilling with water or foam. When new drill pipes are added to the drill string, it is recommended that a half pint (quarter of a liter) of rock drill oil is poured into the pipe to provide a good internal coating and helps prevent the hammer from running dry at any time.
The grade of rock drill oil will be determined by the ambient temperature at the drilling site. If the ambient temperature is between 0 and 25 degrees centigrade, then a 30 grade oil should be used. If the ambient temperature is greater than 250 degrees centigrade, then use a 50 grade oil.}

They can withstand temperatures ranging from –49°C to +55°C. All control devices for the winches can meet EMC requirements according to MILSTD461F.}

^Precision

^{For optimum penetration levels in various drilling conditions, to crush rock effectively it is imperative to maintain a precise button protrusion and button profile for each carbide tip.

Thanks for grinding systems. When combined with a regular, comprehensive maintenance routine, these systems can effectively improve efficiencies and reduce operating costs.

Grinding systems are capable of restoring the profile of tungsten carbide tips on any type of button bit, including DTH bits, Threaded, and Raise Bore Cutters.

• Size: from smaller 26mm (1") bits to oversized 1100mm (43") bits
• Environment: from small operations to large-scale production environments and remote locations including underground and surface drilling, and mobile grinding stations.
• Budget: economical solutions are available for budget sensitive operations that require small diameter drill bits and/or low volumes.
• Mounting: CME systems can be rig mounted or stationary.
• Operation: hydraulic, pneumatic or electric options are all available.}
