We put limestone screenings in our horse arena years ago and in spite of going over it with a landscape rake fairly regularly, it's gradually packed so hard it's almost like concrete. I can break it into large pieces with a lot of effort with my bucket, but it's slow going and then I have huge pieces that are hard to break up.


Rental Equipment. Because of the large capital investment involved and the unique expertise required, it is not unusual for dredging contractors to rent some of their equipment, such as additional tugs or scows. For this example, dredging equipment is assumed to be owned by the contractor. Selection of Equipment.

Impact Crushers – VSIs and HSIs. Impact-style crushers include VSIs, as well as horizontal shaft impactors (HSIs), and are best used with less abrasive rock types, like limestone. These types of machines break apart material by the impacting forces of certain wear parts known as blow bars and impact plates or toggles.. Some operations also use impact-style crushers after they have …

4. Swing the sledgehammer a full 180 degrees to hit the rock. Starting slow, swing the sledgehammer above your head and down onto the rock using your arms and legs to do the majority of the lifting. Keep hitting the same spot again and again. Eventually, a small fault line will appear on the surface of the rock.


The cost of hydraulic excavator for 10m 3 excavation = 0.04125x5000 = Rs.206.25 Likewise, based on the capacity of other equipment, labors etc., their cost is calculated. Contractors profit is also added to the total cost of labors and machineries. Then grand total gives the rate of excavation per 10m 3 of soil excavation.


The size of the material could be 100's of cu.yds, and the energy will be quickly absorbed. This is why it is recommended to work from a bench so the rock has somewhere to break out. We recommend when trenching in limestone or medium hard rock, to use a 3,000 – 5,000-ft. lb. breaker.


Step 1 - Make a Rough Outline. Using dark markers or spray paint get a rough outline of the required shape and design on the limestone block. If you are a beginner and lack experience in cutting or carving limestone it is a good idea to start with medium-sized blocks of limestone as they are not only relatively easier to use but also painlessly easy to manage.


After the rough breaking, steel and iron equipment are added to remove the steel bars and iron blocks in the waste concrete, which will eliminate the damage of steel bars and iron blocks to the equipment without affecting the production. Generally, the impact crusher, the fine crushing jaw crusher or the cone crusher is used as the secondary ...

Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones. Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering—chemical weathering. With this process, water that is slightly acidic slowly wears away stone.
