Sand and Gravel Separation Equipment

The sand and gravel separation production line is an industrial system that integrates mechanical screening, crushing, cleaning and classification functions.

The characteristics of the sand and stone separation production line
High efficiency in resource recovery, strong processing capacity, excellent environmental performance, high automation level, strong adaptability, and good equipment durability.
The application of the sand and stone separation production line
.1. Concrete mixing station: During the production process of the mixing station, a large amount of residual concrete, wastewater and waste residue from cleaning the mixing vehicles and equipment will be generated. These wastes contain a large amount of sand and stone resources. The sand and stone separation production line can process these materials, separate the sand and stone, and clean them to meet the standards for reuse, which can be used again in concrete production, saving sand and stone raw materials, reducing waste emissions, and reducing environmental pollution.
. Benefits: Reuse, saving raw materials, reducing waste emissions, and reducing environmental pollution.
.2. Construction site: Construction will produce a large amount of construction waste, which contains many sand and stone components. Through the sand and stone separation production line to process the construction waste, the sand and stone can be separated from other impurities and processed to be used for site backfilling, road base laying, etc., achieving the resource utilization of construction waste, reducing the amount of landfill, and reducing waste pollution.
. Benefits: Achieving the resource utilization of construction waste.
.3. Mining and processing: During mining, a large amount of mine waste and sand and stone mixtures will be produced. The sand and stone separation production line can screen and separate these materials, extract the sand and stone that meets the requirements, and use them for construction sand, road construction, etc., improving the utilization rate of mining resources, and also reducing the environmental damage caused by mining.
. Benefits: Improving the utilization rate of mining resources.
.4. Water conservancy project construction: During water conservancy project construction, a large amount of mud, sand and other materials will be produced, such as the淤泥 (sludge) and sand and stone mixture produced during river dredging. Using the sand and stone separation production line to process these materials, the sand and stone can be separated and used for construction projects, while the treated sludge can be subjected to harmless treatment or used for land improvement, which is conducive to the ecological protection of water conservancy projects.
. Benefits: Waste utilization.
.5. Road construction project: Road construction requires a large amount of sand and stone materials, and during the construction process, some sand and stone waste will also be generated. The sand and stone separation production line can recycle and process these wastes, separate the qualified sand and stone for reuse in road construction, reducing project costs and resource waste.
. Benefits: Waste recycling, reducing project costs, and reducing resource waste.
The equipment composition of the sand and stone separation production line
This production line is mainly composed of feeding equipment, separation equipment, cleaning equipment, conveying equipment, control system, etc.

FAQ

(1) The feeding speed is too fast (exceeding the designed processing capacity of the production line, for example, the feeding volume of the 200t/h production line suddenly increases to 300t/h); (2) The materials are caking (due to excessively high moisture content, the sand and stones are glued together, forming mud blocks with a diameter greater than 100mm); (3) The gap between the equipment is too small (the distance between the conveyor belt and the hopper is less than 50mm, or the deflector plate at the discharge port of the screening machine is misaligned).
(1) The content of mud in the feed is too high (the moisture content of the raw material mud is greater than 15%), exceeding the processing capacity of the equipment; (2) The stirring speed of the separator is abnormal (too high causing material splashing, too low resulting in insufficient mixing); (3) The cleaning water flow is insufficient (the pump pressure is less than 0.3 MPa, or the spray head is blocked); (4) The mesh size of the screening net is misaligned (the interface between coarse and fine aggregates for screening is confused).
