After working in mines and quarries for a long time, the most troublesome issue is that hard rock cannot be drilled. For ordinary Drilling Rigs, when encountering granite or basalt, the drill bit wears out quickly while the drilling speed is slow, and they can't drill many holes in a day. What's worse is that there are many equipment failures, and today the drill gets stuck while tomorrow a part needs to be replaced. As a result, the project schedule is delayed, and the client is constantly pressured by the client.
The actual pain points of the customers are quite real: can the equipment withstand hard rock, is the failure rate high, is the operator easy to get familiar with, and is the maintenance cost expensive. Many construction sites only consider the price when purchasing equipment, but when using it, they find that the fuel-efficient ones lack power, the powerful ones consume too much fuel, and it's difficult to find maintenance parts. In the end, the overall cost is not low at all.
Anneng's Down-The-Hole Drilling Rigs are designed to address these practical problems. The principle of sub-hole drilling is very straightforward - the impactor follows the drill bit down to the bottom of the hole, and the energy acts directly on the rock. Unlike top-hammer drilling rigs, the energy needs to be transmitted along the drill pipe, and the harder the rock, the less power it has. We match the impact system and the rotation system well, so the equipment can also output stably in hard rock conditions. From the perspective of application, these devices cover scenarios such as mining, quarrying, slope support, and infrastructure blasting holes. The hole diameter and depth can be adjusted according to the working conditions. Anneng's product line is not limited to this type. Excavator Converted Drilling Rigs are suitable for customers who already have excavators and want to convert them into drilling equipment. The Drilling And Splitting Machines integrate drilling and splitting together, eliminating the trouble of secondary transportation. When encountering particularly hard rock layers, Ultra-high pressure Rock Splitters and Mining Rock Splitters can be used together, drilling first and then splitting, with much higher efficiency than pure crushing. Overall, Drilling Rigs are not an isolated machine, but a set of combinable construction solutions. In practice, the most obvious feedback from customers is that the drilling speed has increased, and the number of drilled holes per unit time has increased; the wear of the impactor and the drill pipe has decreased, and the frequency of replacement is low. There is no need to wait for parts every day at the construction site. The operation interface of the product has been simplified, and experienced operators can master it in half a day, and the training period for new operators is also short.
Product features:
The sub-hole impact directly acts on the bottom of the hole, the drilling efficiency for hard rock is high, and the drilling speed is stable.
The impact system and the rotation system are matched and optimized to reduce common faults such as stuck drill bits and broken drill rods.
It can be combined with splitting equipment to form a drilling-splitting integrated solution, suitable for different hardness rock layers.
Tips for use:
Before starting, check the oil level of the impactor and the sealing of the air pipe to avoid a decrease in impact force due to air leakage.
Adjust the advancing pressure according to the hardness of the rock during drilling. Do not forcefully drill through hard rock, as it is prone to burning the drill bit.
Clean the drill pipe threads and the impactor in time after work to extend the service life of the vulnerable parts.
Anneng's sub-hole drilling rigs are not just selling a single piece of equipment, but helping you calculate the efficiency and cost of drilling through hard rock. Choosing the right model and matching the right solution can ensure fewer downtime and more drilling in the construction site.
