At present, the country's environmental protection has entered a critical stage, especially in recent years when the smog in winter has become severe. Various provinces and cities have successively issued relevant laws and regulations such as traffic restrictions and mining restrictions. Low-carbon environmental protection and green development have become the development direction of various industries. Especially the gravel aggregate industry. The traditional sand and gravel aggregate production can no longer meet the current urban development needs. In order to adapt to the current social development, mine crushing equipment companies have developed new types of environmental protection machinery. Environmentally friendly sand and gravel production lines have become the development goals of major enterprises.
The main equipment used in the sand and gravel production line are: vibrating feeder, jaw crusher, impact crusher, vibrating screen, etc. So how can we reduce the pollution to the environment? How to configure the gravel production line to achieve green production?
Sand and gravel production line
The process of sand and gravel production line is roughly: (silo) ---- feeder ---- jaw crusher ---- impact crusher ---- vibrating screen (finished stone), the middle machine Conveyors can be used to connect between them, and cone crushers, dust removal equipment, etc. can also be equipped according to the needs of users.
The first is the selection of the crusher. Under the premise of meeting the crushing ratio determined by the process, similar equipment should be selected as much as possible with large crushing force, uniform particle size, small vibration amplitude, and good dust-proof effect. For example, the Bellian jaw crusher adopts deep cavity crushing, high efficiency and energy saving, and the flywheel design can effectively reduce vibration, make the machine run more smoothly, and meet the requirements of energy saving and environmental protection.
Furthermore, on the basis of ensuring the screening efficiency, the vibrating screen should try to choose equipment with low vibration and noise. At present, there is also a new type of HX series vibrating screen, which is self-lubricating with thin oil, and the lubricating oil is replaced every 3 to 6 months, which greatly saves the cost.
From the concept of environmental protection, the sand and gravel production line should be located far away from residential areas and office areas. At the same time, the crushing and screening workshop should be located in a concave area as much as possible to avoid dust and noise pollution.
In addition, the operator should strictly wear protective equipment such as dust masks/earplugs during operation. The sewage from the sand and gravel production line can be recycled, deposited and reused. It is necessary to ensure the smooth discharge of sewage from the system, and the waste residue must be transported to the designated stockyard.
The editor warmly reminds everyone: During the production process, it is necessary to operate according to the regulations. If necessary, the crushing, screening and sand making parts can be closed to achieve the purpose of dust prevention and noise prevention. When choosing a manufacturer, you should choose an enterprise with rich experience and integrated production and sales. The editor recommends Bellian Machinery to consumers. It is a large-scale mining machinery manufacturer in China. It integrates R&D, production and sales. It has rich experience and technology. Tailor-made" sand and gravel production line, good after-sales service, trustworthy.
