The sand and gravel production line is a combination of sand production line and stone production line, which can produce sand and stone at the same time. The complete set of sand and gravel production line equipment is a combination of various equipment specializing in the production of construction sand and stone. It can combine various rocks, ore, Limestone, basalt, granite, pebbles, river pebbles, etc. are made of various sizes of construction sand and stones, which have uniform particle size, regular shape, and high compressive strength. They are far more in line with construction requirements than natural sand and can improve the building quality.
The complete set of sand and gravel production line equipment produced by our company has the advantages of low investment, high output, reliable performance, reasonable design, convenient operation, high work efficiency, and large processing capacity, features such as cracks and high compressive strength. The most important is that the complete set of sand and gravel production line equipment produced by our company is easier to maintain and maintain. The wearing parts are made of the latest domestic high-strength wear-resistant materials, with low loss and long service life, which can bring considerable economic benefits to customers.
According to the hardness of the ore, our company divides the sand and gravel production line into a two-level crushed sand production line and a first-level crushed sand production line.
The process of the secondary sand and gravel production line is roughly as follows: (silo)-vibrating feeder-jaw crusher-impact crusher-circular vibrating screen-sand making machine-bucket sand washing machine-fine sand recovery machine-finished products of various specifications, each machine is connected with a belt conveyor, and the finished sand and gravel of various specifications are gradually output from behind the circular vibrating screen.
The large ore is evenly sent to the jaw crusher by the vibrating feeder for coarse crushing. The coarsely crushed material is sent to the impact crusher by the belt conveyor for crushing and shaping, and then transported to the vibrating screen for screening. The materials that meet the requirements of the finished product size are transported to the finished product area (pebbles) or the bucket sand washing machine for cleaning. After cleaning, the finished product conveyor belt outputs the machine-made sand product; the waste water discharged from the sand washing machine contains some lost fines. For sand, a fine sand recovery machine is installed at the end to recover fine sand (the recovery rate can reach more than 90%). The recovered fine sand can be transported to the manufactured sand product area through the finished manufactured sand belt; the finished product size is not reached after screening. The required materials (larger pieces) are returned from the vibrating screen to the sand making machine for reprocessing, forming a closed circuit for multiple cycles. The granularity of the finished product can be combined and classified according to the needs of users. If dry production process is selected, coarse and fine powder separator and dust removal equipment can be equipped.
The process of the first-level crushed sand and gravel production line is roughly as follows: (silo)-vibrating feeder-heavy hammer crusher-circular vibrating screen-sand making machine-wheel bucket sand washing machine –fine sand recovery machine -finished products of various specifications, each machine is connected with a belt conveyor, and the finished sand and gravel of various specifications are gradually discharged from behind the circular vibrating screen.
The large ore is uniformly fed to the heavy hammer crusher by the vibrating feeder. After crushing, the materials are sent to the circular vibrating screen by the belt conveyor for screening, and the materials that meet the requirements of the finished product size are transported to the finished product area (pebbles). Or bucket sand washer for cleaning. After cleaning, it is transported to the finished product area by the belt conveyor to be the finished machine-made sand. The waste water discharged by the sand washer contains some lost fine sand. A fine sand recovery machine is installed at the end to recover the fine sand. (The recovery rate can reach more than 90%). The recovered fine sand can be transported to the machine-made sand product area through the finished machine-made sand belt; the materials (larger pieces) that do not meet the requirements of the finished product particle size after screening are returned to the machine-made sand the sand machine is reprocessed to form a closed circuit for multiple cycles. The granularity of the finished product can be combined and classified according to the needs of users. If dry production process is selected, coarse and fine powder separator and dust removal equipment can be equipped. For more information, you can click: www.lydhcrusher.com
