What equipment is used to process marble waste into gravel?

We all know that marble is an excellent decorative material. When large marble blocks are carved or cut to create decorative items, some waste and residue are inevitably produced. It is understood that this waste can be processed into gravel for reuse after certain treatments. So, is the gravel made from marble waste marketable? What machinery is used for processing marble?

Marble waste processed into gravel enjoys strong market demand! Primarily composed of calcite, limestone, serpentine, and dolomite, marble is crushed into gravel specifications of 0-5mm, 5-10mm, and 10-20mm. This gravel exhibits characteristics such as dimensional stability, high rigidity, excellent wear resistance, minimal thermal deformation, and extended service life. It is primarily sold to the construction, chemical, rubber industries. In road construction, it mixes with cement and asphalt to form robust subbase fillers. It also serves as artificial sand, foundry sand, marble mosaic material, and filler for coatings and plastics. Thus, crushed stone from marble waste not only sells well but commands high prices.

What equipment is used for processing marble waste?

Typically, marble scrap consists of irregularly sized fragments with a Mohs hardness ranging from 2.5 to 5. Considering the material's characteristics, a combination of jaw crusher + cone crusher is recommended for processing marble.

1. Jaw Crusher

Performs primary crushing of marble, handling materials under 1.2 meters. Utilizing a compression crushing principle, its deep V-shaped crushing chamber eliminates dead zones, increasing throughput. Equipped with oversized bearings and a forged main shaft, it withstands greater crushing forces. The flywheel design effectively reduces vibration for smoother operation, while hydraulic components ensure reliable performance and low failure rates. Adjustable discharge opening from 10-350mm with comprehensive finished product specifications.

2. Cone Crusher

Performs fine crushing of pre-crushed marble. Employing a laminar crushing mechanism, this method delivers superior results for high-hardness materials. Key features include a large-diameter spindle, heavy-duty main frame, and an automatic control system with an independent oil lubrication system. These elements collectively ensure robust durability during marble processing. Reliable operation is achieved through hydraulic motor-adjustable discharge openings (3-60mm range, equivalent to 12/13mm aggregate). The finished product exhibits a predominantly cubic structure, significantly reducing needle-like and flake-shaped particles. Wear-resistant components minimize long-term operational costs and extend service life.
