Marble is a type of recrystallized limestone formed under high temperature and pressure, which gives it a dense, durable structure and aesthetic appeal. Apart from being widely used in construction and decorative projects, the leftover material from marble processing also has high value. These by-products can be crushed into fine aggregates and powders, which are widely used in the chemical industry, fillers, and construction materials.

Dolomite is a carbonate mineral with a hardness of 3.5-4 and a specific gravity of 2.85-2.9. It is commonly found in gray-white color and has a similar appearance to limestone. Dolomite can be classified into iron dolomite and manganese dolomite. Due to its versatile properties, dolomite is widely used in building materials, ceramics, glass and refractories, chemical industries, agriculture, environmental protection, and energy-saving applications.

As the demand for sustainable and high-performance construction materials rises, river pebbles—composed primarily of silicon dioxide—have become increasingly valuable due to their hardness, durability, and environmental friendliness. Traditionally used in landscaping and high-grade concrete applications, pebbles now play a key role in eco-friendly construction, and modern processing methods are evolving to match that need.

Feldspar is one of the most abundant minerals in the Earth's crust, widely used in ceramics, glassmaking, and even as a filler in paints, plastics, and rubber. Generally, feldspar appears milk white, but due to the presence of different impurities, it may also take on hues of yellow, brown, light red, or dark gray, and in some rare cases, even exhibit a beautiful iridescence that enhances its decorative value.

Gabbro is a coarse-grained, dark-colored intrusive igneous rock mainly composed of plagioclase and augite. Known for its hardness, density, and durability, gabbro is widely distributed in the deep oceanic crust and is a common raw material in large-scale construction projects. It is extensively used in producing crushed stone, aggregate bases, high-grade concrete, decorative stone, and road foundation materials. As demand for construction aggregates continues to rise, the mobile crushing station has become an essential piece of equipment for efficient gabbro crushing and processing.
