River pebble material is initially broken by a river pebble sand making machine, and the coarse material is then transported to a secondary crushing machine for further fine crushing. The finely crushed stone is separated into two types of gravel by a vibrating screen. The gravel meeting the feed particle size requirements of the sand making machine is processed into sand, while the remaining material is returned for further fine crushing. Part of the gravel fed into the river pebble sand making machine is made into sand, which may be cleaned by the sand making machine (optional) before being processed into finished sand. The other part is sent back into the river pebble sand making machine for further crushing.

Working Principle

The River Gravel Sand Making Machine is a typical application in the current artificial sand industry, serving as an alternative to rod mill sand making machines, impact sand making machines, cone crushers, and straight-through sand making machines. River gravel is a hard, wear-resistant, and chemically stable stone with natural characteristics of high compressive strength, wear resistance, and corrosion resistance. It is widely used in the engineering field for the production of mechanism sand and stone shaping in water conservancy and hydropower projects, expressways, highways, high-speed railways, passenger rail lines, bridges, airport runways, municipal engineering, and high-rise buildings. Due to its widespread distribution, abundant resources, relatively low collection costs, and high application value, it has become an ideal choice for stone used in courtyards, roads, and construction projects.
