It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.  

The main components of submarine hammer drilling equipment include the drill rig, hammer, drill pipes, and the drill bit. The drill rig is often mounted on a surface vessel or a floating platform and is designed to support the excessive weight and dynamic forces encountered during drilling operations.

Safety Features

In the ever-evolving fields of mining and construction, the need for efficient, precise, and powerful drilling techniques is paramount. Among various methods, down-the-hole (DTH) hammer drilling has emerged as a pivotal technology, providing a range of benefits that enhance productivity and reduce operational costs.

The applications of the ZJ slurry pump are vast and varied. In the mining sector, it is extensively used for transporting mineral slurries and managing tailings. Similarly, in the construction industry, it plays a vital role in moving cement and other aggregates. Water treatment facilities also utilize ZJ pumps for sludge transfer, managing the critical process of waste management effectively.

2. Positive Displacement Pumps For more viscous slurries or when maintaining a consistent flow despite variations in pressure is essential, positive displacement (PD) pumps are ideal. These pumps work by trapping a fixed amount of slurry and forcing it through the discharge. PD pumps can handle thick and abrasive slurries, making them a preferred choice in mining and mineral processing applications.

Conclusion

1. Greater Efficiency DTH drilling significantly reduces drilling time when compared to rotary methods. The direct impact of the hammer allows for faster penetration rates, enabling operators to cover more ground in shorter periods. This efficiency is especially critical in industries where time equates to money.

In mining applications, high density slurry pumps play a crucial role in transporting mineral slurries from the processing plant to the tailings storage facility. Their robust construction and efficient design help minimize downtime and maintenance costs, ultimately improving productivity and profitability for mining companies.
In the construction industry, high density slurry pumps are utilized for handling concrete mixtures, grout, and other construction materials. Their ability to handle high-density slurries with ease ensures smooth and efficient operations, leading to faster project completion times and cost savings.
