Selection of Sand Making Equipment for Premium Basalt Sand Production Line

Basalt is a major component of the Earth’s continental crust. It is widely distributed, easy to obtain and abundant in reserves. As a high-quality raw material for manufactured sand, basalt features high hardness, good wear resistance, great solidity and strong compression resistance. Manufactured sand made from basalt is very popular and widely used in the construction industry.

However, precisely because of its excellent physical properties, basalt’s high hardness and wear resistance also make it quite difficult to crush and process into sand. It has become an urgent task to solve this problem, optimize the traditional production process, and improve the quality and output of finished sand.

With the continuous development of technology, many sand making machines and complete production lines have been launched specially for processing hard rock in the high-quality manufactured sand market.

The common processing flow of a basalt sand making production line is divided into three stages: primary crushing, secondary crushing, and sand making & shaping.

The whole production line mainly consists of a feeder, jaw crusher, belt conveyor, cone crusher, vibrating screen, sand making machine and sand washing machine.

Technological Flow of Basalt & Hard Rock Sand Making Production Line

First, bulk basalt materials are sent by the feeder to the jaw crusher for primary crushing.

The crushed raw materials are then transported by the belt conveyor to the cone crusher for medium crushing.

After crushing, qualified materials are delivered to the sand making machine, while unqualified materials are sent back to the cone crusher for re-crushing.

After sand making, finished materials are screened by the vibrating screen. Unqualified particles are returned to the sand making machine for reprocessing. Qualified finished sand is cleaned by the sand washing machine and then sent to the finished product stockpile.

Choosing the Right Equipment Is the Key to Building a Premium Basalt Sand Making Line

Basalt raw materials are usually large in size. Therefore, the jaw crusher is adopted as the primary crusher, thanks to its large feeding size and capacity to handle high-compression-strength materials. It has a large crushing ratio and high output, and produces well-graded particles, providing stable material supply for the follow-up crushing process.

GME cone crusher adopts the laminated crushing principle, which optimizes particle shape. Finished grains are cubic in shape. It features high efficiency, low operating cost, good particle quality and stable operation with high reliability, making it the ideal choice for secondary and tertiary crushing of medium-hard materials.

As professional equipment in the sand making industry, SBM sand making machines save energy, have a long service life and wide application range. They integrate sand making and shaping into one process. The finished sand is mostly cubic with low content of flaky particles and excellent quality, fully meeting the demand for high-quality manufactured sand in the market.
