How to Choose the Right Paving Breaker for Demolition or Construction Work

The paving breaker is one of the most industrious machines in any construction site. Be it removing an old pavement or demolishing a tough concrete structure, getting the right breaker is key to a quick and easy job. The various specifications available in the market can confuse buyers. Below is a helpful guide that will assist in buying a paving breaker and an insight into three models produced by Mindrill.

1. Understand the Purpose of the Equipment

A paving breaker is otherwise referred to as pneumatic jackhammers or concrete breakers. These are machines used to break up tough surfaces like asphalt, concrete, and rock. The machines are used in road work, utility trenching, bridge and pavement repairs, building demolition, and post-construction clean-up. The rock drifter machine is designed to drill holes in rocks, but the paving breaker works by impact on the surface itself.

2. Determine the Suitable Weight Class for the Purpose

There are basically two main types of paving breakers: the light to medium breakers which have weight ranging between 15 kg and 20 kg, and the heavy breakers weighing more than 30 kg. It is important to note weight as the first consideration:

• The light to medium breakers are easy to handle and fit well for floor demolition, pavement patching, utility and maintenance work requiring precision.

• The heavy breakers provide greater impact energy per stroke and, thus, are best suited for use in thicker concrete or compact roads.

An underweight breaker will result in more time required for the work, while overweight breaker will make handling difficult.

The Mindrill range of paving breaker tools has been designed to suit all applications, giving operators the ability to tailor the tool to the job. The MPB1210 is a light-weight 20 kg machine that has been developed specifically for lighter construction, plant maintenance and surface tasks. The MPB1230 is a medium to heavy machine at 31 kg that provides higher impact energy for more difficult pavement and demolition applications. Lastly, the 38 kg MPB117L has been designed to take on the toughest applications involving dense concrete and compacted surfaces.

3. Consider the Type of Power Source

The most common type of breaker that can be found on the market is the pneumatic variety, using compressed air from an air compressor to power the mechanism. Pneumatic breakers are renowned for their durability, easy maintenance and reliability in difficult situations, which makes them an industry standard tool for mines, construction projects and demolition. As long as you have an air compressor running to power other tools, such as pneumatic drills, then a pneumatic breaker is going to be your best bet. This applies to the MPB1210, MPB1230 and MPB117L Mindrill tools.

4. Consider the Shank Size

 

The shank refers to the component used for holding the chisel, moil point or spade (tool bits). Different manufacturers provide different models with different shank sizes; thus, it is important to be sure about compatibility of the breaker selected with your tool bits.

5. Internal Mechanisms of the Breaker

All breakers do not share similar mechanisms internally. Some of these include tuned valve mechanism and reversible piston with lubrication grooves which significantly affect the efficiency of operation. Proper design of the valve mechanism increases the number of blows, but decreases the waste of air in the process, making the operation more efficient. A reversible piston mechanism increases even wearing off of internal parts, which means longer durability of the tool. Mindrill MPB1210, MPB1230, and MPB117L all operate on this principle of construction.

6. Take Into Account Operator Comfort and Ergonomics

Prolonged operation of any tool will lead to operator fatigue, so it is important to take into account ergonomic considerations when selecting a breaker. Prefer models with anti-vibration handles and even weight distribution to avoid repetitive strain injuries.

7. Take Into Account Serviceability and Availability of Parts

It goes without saying that breakers work in challenging environments with dust and abrasion, so it is natural that there will be wear and tear. Make sure that before making your purchase, you are able to service the tool easily, and there are parts available.

8. Selecting a Trustworthy Tool Manufacturer

In the end, the reputation of the manufacturer is just as important as the tool itself. Manufacturers who have been in the business of mining and construction equipment for a long time and have their products tested and certified have better tools on average. Mindrill Company, for example, has been making pneumatic and hydraulic tools since 1971 and offers a wide selection of pavement breakers suitable for both regular maintenance and heavy demolition in a variety of weight classes. Among them are such tools as MPB1210, MPB1230, and MPB117L.

Conclusion

Choosing the correct paving breaker depends on matching the breaker with your material, project size, and machine configuration. Think about things like the weight class, the power source, shank compatibility, the construction inside the machine, ease of use, and after-sales services. Doing this will make the process easier and ensure you are not wasting time on your equipment. In case you are still deciding, then try Mindrill’s MPB1210, MPB1230, and MPB117L.

 

 

Hydraulic Drifters for Mining, Quarrying & Tunneling: Exploring the MHD100X, MHD100, and MHD1838HD+

Drilling rocks has always been the critical process in mining, quarrying, and tunneling operations. Whether it is an advance made underground, benches drilled at a quarry, or holes drilled to insert rock bolts, all depend upon a single machine working consistently: the hydraulic drifter. In contrast to the earlier pneumatic rock drillers, the hydraulic driller uses high-pressure hydraulic fluid to produce percussive impact force, which results in higher penetration rate, quieter operation, less vibration, and efficient use of energy. Out of the several types of drifters currently employed on drilling rigs and jumbos, the MHD100X, MHD100, and MHD1838HD+ make a representative sample of scaling of drifter design to various types of rocks.

Importance of the Hydraulic Drifter

The drifter is essentially the business end of a drill rig; that part of the drill which is attached to the feed arm and strikes the drill rod, imparting its impact energy to the rod down to the bit. In hydraulic systems, it is done via the impact energy from a hydraulically driven piston impacting the shank adapter at a very high frequency and independent rotation. The fact that the percussion and the rotation are separate actions is what sets the hydraulic drifter apart from others; the operator can independently control the impact energy, the rotation and feed rate based on the hardness of the rock, saving on the rod wear and improving hole straightness.

MHD100 and MHD100X: The Mid-Class Power Duo

The MHD100 falls into the mid-class of hydraulic drifters, which are used for face drilling, bolting and general mining production in underground mines and tunnel developments. Drifters from this weight class are preferred since they achieve a compromise between having sufficient energy for reliable penetration rates in medium to hard rocks and being small and light enough to be mounted on smaller-sized jumbos and single-boom rigs commonly used in narrow vein and development mines.

In the case of MHD100X, it is easy to guess what it is – an advanced version of the same drifter in the same weight class – the "X" in the names of drifters usually means an improved sealing kit, better wear resistance or advanced hydraulics that ensure better penetration rate and longevity of the drifter without increasing its size and shape. For customers who operate the MHD100, the MHD100X is a logical choice for upgrade, which retains the same mounting and rod specifications as the previous version, yet offering better drilling efficiency and durability. Such improvements are very valuable in the mining industry since the cost of rig modifications is far greater than the cost difference between the versions of the drifter.

MHD1838HD+: Designed for Heavy Duty

The MHD1838HD+ is considered one of the heavy duty class drifters, which usually is designed for high-speed drilling operations in underground metal mines, large tunnel boring and heavy duty quarries, where the rock mass or holes are tougher or bigger. The "HD" means heavy duty construction with strengthened housings, larger bores inside for higher hydraulic flow, and construction parts that can work with high-frequency impacts without early fatigue. The "+" usually means a newer version of the machine with some improvements in durability or flushing/dust handling of the drill steel or other features that would make rebuild intervals longer.

As the heavy duty drifters, including 1838HD+, produce more impact energy with each stroke, they usually work with bigger rigs and higher capacity hydraulic power packs. In case there are two options – a medium class machine and an HD+ machine, you have to decide whether you need faster drilling operations or smaller equipment cost, hoses and pumps size, and heading or bench dimensions.

Selecting the Proper Drifter for the Application

In reality, the choice of the appropriate model such as the MHD100, MHD100X, and MHD1838HD+ is determined by a handful of practical considerations:

Hardness and abrasion resistance of rock – harder rock usually warrants the extra impact energy that comes with an HD-type drifter.

Compatibility with rig setup – weight and mounting dimensions of the drifter need to be compatible with the existing boom and feed assembly.

Hole size and depth – bigger holes and greater depths require increased capacities.

Production rate – continuous production drilling requires robust machines designed for frequent and constant high-frequency operation, whereas sporadic bolting and/or development operations can be successfully performed using mid-range drifters.

Maintenance facilities – good in-house maintenance facilities may allow getting additional efficiency out of higher performance machines.

Conclusion

Although hydraulic drifters are only a minor physical part of a large drilling rig, they form the greatest tool that will enable control of the rate of penetration, durability of rods, and total drilling costs. No matter whether it is a mid-size class MHD100 or MHD100X to perform normal face and bolting work, or even a bigger MHD1838HD+ for hard production drilling, it all comes down to selecting the right size of the drifter for the rock and rig in question.
