Nowadays, China’s infrastructure projects are increasing, and the demand for mechanism sand for infrastructure is increasing sharply. The stone processing mechanism sand industry has a good prospect. In addition, the country has strict environmental control on sand and stone factories, it is a wise choice to build a large fully enclosed environmental sand production line to ensure the long-term stable operation of sand and stone factories. This paper introduces the equipment that needs to be configured for the fully enclosed environmental protection sand production line, and the customer case is attached for your reference.
I. Equipment configuration of large fully enclosed environmental protection sand production line
It is recommended to adopt the three-stage crushing process to build a large-scale sand making factory. The three-stage crushing process is coarse crushing, medium and fine crushing and sand making. The crusher equipment used is jaw crusher, cone crusher/impact crusher and sand making machine. Sand making machine has two functions of sand making and shaping. The shape of the finished product is better, the new environmental protection design is added, automatic circulation in the vortex chamber, and the dust does not overflow. In addition, a sand washing machine is needed to clean the mechanical sand, so that the finished product is more pure.
Note: Cone crusher is suitable for processing granite, basalt and other high hard materials. Impact crusher is suitable for processing bluestone, coal gangue, dolomite and other medium hard materials.
II. Environmental protection measures of fully enclosed sand production line
Under the situation of strict environmental inspection, it is not enough to build a fully enclosed workshop to meet the environmental requirements. Indoor pollution sources mainly include dust, sewage and noise. A series of environmental protection measures should be taken to prevent pollution and ensure environmental protection standards in production.
Dust collector is installed to collect dust at the material outlet of the production line, the conveyor belt is equipped with a sealing cover to prevent dust spillover during transportation, crushing equipment is equipped with a sound insulation cover to reduce working noise, sewage sedimentation tank is built, sand washing wastewater is filtered, and the filtered water can be used for sand washing again to achieve zero discharge of waste water.
