The general sand and gravel production line mainly includes several key links such as feeding-crushing-sand making-screening and washing-transportation. Specific equipment selection can be tailored to its own process needs. Sand and gravel production seeks environmental protection, and closed design helps. For sand and gravel factories, environmental protection is mainly limited to two aspects: dust and noise. Usually, closed production can achieve a large extent of green environmental protection.
1. The installation of multi-effect dust removal equipment is necessary. At the same time, the production line adopts a partially enclosed design, and a dust cover is used to collect the generated dust, which can reduce a large extent of dust pollution;
2. The enclosed prefabricated house design can significantly reduce noise pollution and realize one of the important conditions for environmentally friendly sand and gravel production lines.
How to configure a closed environmentally friendly sand and gravel production line? Sand washing and screening is the key. In addition to sand washing equipment, Longding Environmental Protection Technology's sand washing production line to meet domestic environmental protection requirements should also be equipped with crushers, sand makers, vibrating screens, feeders and fine sand recycling machines. It is composed of various equipment such as machines. When the production line is operating, each equipment transfers materials between each other through belt conveyors. When designing the sand washing production line, planning should be carried out based on the hardness, grain size and other characteristics of the materials processed on site!
Production process of sand washing production line
1. The mined ore material is evenly sent to the jaw crusher through the vibration feeder for rough crushing, and the roughly broken material is then sent to the cone crusher through the conveyor for fine crushing.
2. The finely broken materials are sent to the vibrating screen by the conveyor for screening. Materials that do not meet the feed particle size of the sand making machine are screened out and transported to the cone crushing in the previous step for crushing again to meet the feed particle size of the sand making machine. The materials with the grain size are sent to the sand making machine for further sand making and fine crushing.
3. The processed fine sand and gravel are transported to a vibrating screen by a conveyor for screening treatment. The sand that meets the particle size requirements of the finished product is sent to the sand washer for dust removal and cleaning. After cleaning, it is sent to the finished product storage bin by a conveyor belt, but the sand that does not meet the requirements are returned to the sand making machine by the conveyor belt for re-processing until the requirements are met.
