: , Song Dynasty < : <=# : Introduction to pebble filter material: Pebble (gravel) filter material, commonly known as support layer filter material or cushion filter material, is divided into (natural) cobblestone and (machined) quartz gravel. kind. The pebble filter material is excavated, screened, and water-selected from natural rivers. It is spherical in pure white and variegated colors, and processed into organic pebbles and quartz gravel. This product has an impurity-free density, silicon content of .%, and mechanical strength. It is used in water plants, mechanical filters, anion and cation exchange and other necessary materials. usual format:. Cobblestone products include: natural-colored machine-made cobblestones, river pebbles, rainstones, dry-bonded stones, spray-painted stones, landscaping stones, petrified wood, cultural stones, natural-colored marble rice and other building decoration materials and high-grade dyed sand for interior decoration. , non-toxic, odorless and non-decolorizing.
: , Song Dynasty < : <=# : Uses of cobblestones: Cobblestones are widely used in public buildings, villas, courtyard buildings, paved roads, park rockeries, bonsai filling materials, garden art and other high-end superstructures.

: , Song Dynasty cobblestones are also widely used in power plant transformers, water treatment filter material cushions, public buildings, villas, courtyards, garden pavements, river embankments, lake bottoms, chemical plants, sewage plants, steel plants, and tap water It is an excellent material of choice for factories and other projects. It has good water purification effect, is easy to flush, has a long service life and is cost-effective. It is one of the main water purification materials currently used in double-layer and three-layer filters. Gravel is produced by crushing and finishing quartz ore. It is widely used in water treatment support layers such as water plants, machine filters, and cation and anion exchange. Our factory is a professional manufacturer of cobblestones, producing various types of cobblestone filter materials such as cobblestones, cobblestone filter materials, black cobblestone filter materials, white cobblestone filter materials, and variegated cobblestone filter materials. Mainly used in water treatment pebbles, pebbles for filter tanks, pebbles for supporting layers, pebbles for cushions, pebbles for filter tanks, etc. The cobblestone filter material produced by our factory is processed by excavating, screening and washing from natural rivers. Pebble filter material is non-toxic, odorless and does not discolor. With hard quality, bright and simple color, pebbles have the characteristics of natural stone that are resistant to pressure, wear and corrosion. &<:
