A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill. .
DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling. .
A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the. .
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to. .
DTH products can be used in the following applications:• Mining- drill and blast holes in open pit mining, where the drill operator will drill several holes, then.

The causes of air compressor oil leakage include phenomena such as oil seepage, oil dripping, and oil spraying, which are usually caused by seal failure, loose connection parts, or blockage of the oil cooler. Oil seepage usually stems from the aging of seals or loose connections..
The causes of air compressor oil leakage include phenomena such as oil seepage, oil dripping, and oil spraying, which are usually caused by seal failure, loose connection parts, or blockage of the oil cooler. Oil seepage usually stems from the aging of seals or loose connections..
First, check that there isn't a very high air demand, or air leak somewhere. If the capacity of the air compressor is really too low, check the following: Check differential pressure over oil separator. Replace separator when necessary. Check and replace compressed air filters (if installed)..
Excessive Oil Pressure: If the air compressor is operating at excessive pressure, it can put undue stress on seals and gaskets, causing them to fail. Improper Oil Level: Maintaining the correct oil level is crucial. Overfilling or underfilling the oil reservoir can lead to leaks..
Worn Seals or Gaskets: Over time, seals and gaskets in your compressor can deteriorate, leading to leaks. High Temperatures: Extreme operating temperatures can cause the oil to thin and leak through seals.
