Sand and gravel production line is a special production line equipment for producing sand and stone for construction. It saves 50% energy compared with traditional sand making machine. It can make rocks, sand, river pebbles and other materials into various particle sizes that meet the requirements of construction sand. The sand produced has uniform particle size and high compressive strength. It is much more in line with construction requirements than natural sand and machine-made sand, and can improve the quality of construction. The finished products produced include stone and artificial sand, so it is called sand and gravel production line.

Working principle of sand and gravel production line: stone is evenly sent to jaw crusher by feeder for coarse crushing, and the coarse crushed material is sent to sand making machine by conveyor for further crushing. The fine crushed material is transported to vibrating screen for screening. The material that meets the finished product particle size requirements is sent to sand washing machine for cleaning. After cleaning, it is output by finished product conveyor belt as finished product; the material that does not meet the finished product particle size requirements is returned from vibrating screen to sand making machine for reprocessing, forming a closed circuit multiple cycles. The finished product particle size can be combined and graded according to user needs. If the dry production process is selected, it can be equipped with a coarse and fine powder separator and dust removal equipment. The crushing system is the heart of the whole set of equipment. Its job is to crush various ore raw materials into finished materials of the required particle size. A comprehensive sand and gravel production line can be composed of multiple crushers, and crushers with different performances are used to complete the crushing of stones. Crushing equipment generally includes jaw crushers, impact crushers, hammer crushers and cone crushers.

Large pieces of stone are evenly fed into the jaw or hammer crusher by the vibrating feeder through the silo for (first crushing) coarse crushing. The coarsely crushed stone is sent to the impact or cone crusher by the belt conveyor for secondary crushing. The main wear parts of the jaw crusher are the jaw plate; the main wear parts of the impact crusher are the hammer and the impact plate; the main wear parts of the hammer crusher are the hammer head; the main wear parts of the cone crusher are the crushing wall and the mortar wall.

Our company produces these wearing parts of crushers. The main materials of hammer heads are high manganese steel, medium alloy steel, bimetallic composite, high manganese steel inlaid with alloy rod, ceramic composite, manganese steel surfacing, high manganese steel inlaid with alloy rod + surfacing, etc. The main materials of crushing wall and mortar wall are high manganese steel and medium alloy steel. The materials of impact plate and plate hammer are high manganese steel, medium alloy steel, high manganese steel inlaid with alloy rod, inlaid with ceramic particles, etc. We will reasonably design and produce these wearing parts according to specific working conditions. The service life of our wearing parts is twice that of other companies. Helping enterprises to produce efficiently and reducing the frequency of downtime is our goal.
