Turning boulders into revenue with the Screening Bucket

A  mid-size well know Road contractor from the north eastern part of India is currently undertaking several Road Construction works for approximately 15 Kms, under the PMGSY and CMGSY Programs of the region.

The PMGSY & CMGSY Program is a national plan to provide with roads to the unconnected villages of India, especially in the hilly and rural areas. Under this program, 300,000 km of roads are about to be repaired & 750 km of new roads will be constructed.

The Customer has a 150 TPH plant with four slab screening and earlier they collected River stone adjacent to the project site with the help of an excavator. The river boulders collected contained with sand and mud which could not be used in crusher as the output aggregates would contain mud and sand, which is not eligible for road projects.

Prior to purchasing MB Screening machine, customer was using manpower to clean the input stratus, which was not only a time consuming activity, but it was highly inefficient in terms of productivity and quality. During the nationwide lockdown, availability of manual labours was extremely less and customer was unable to take out aggregates for their daily use.

They require the following grades for their road construction job.

• 63 mm Down – for GSB;
• 40 mm Down – for WMM;
• 20 mm Down.

Due to non-availability of labour force, their crusher became non-productive and they started buying aggregates from the nearest crushers, which is about 40 Kms away from their project site.

Their buying price was about Rs-600/CFT (cubic feet) for 20mm down & Rs. 400-450/CFT for 40mm down plus the transportation cost, which is an extra burden on them.

After purchasing MB Screening Machines MB-S18 with 20x20mm mesh size which was mounted on Kobelco SK220 heavy machine, in just ONE step they are:

✔ Excavating boulders from the river directly with the help of MB-S18;
✔ Washing/cleaning the sand and muds in the river itself during collection.

Resulting in the elimination of all the costly and ineffective processes of:

• Gathering the river boulders by excavator; 
• Shifting the materials to the site;
• Arranging the cleaning of those boulders manually.

With the help of MB-S18, they obtain the following benefits:

✔ Being able to perfectly clean the soil/mud attached to the boulders;
✔ Cleaning the material directly at the collection point in a faster way;
✔ Higher quantity of raw material available to crush;
✔ These materials can be used as a qualified aggregates for the road construction works.

Today, Customer has successfully eliminated their reliance on third party suppliers, and were also able to reduce their production cost drastically. They are getting much higher productivity with the help of MB-S18 Screening Bucket and the crusher has started production of GSB / WMM material at full capacity.

Customer after fulfilling their own requirement have started supplying aggregates in the local market, which is an helping them to increase revenue.
