crushing and screening plant

In recent years, with the continuous growth of demand for construction, mining and infrastructure construction, the technology and equipment level of crushing and screening plants, as a key link in the production of sand and gravel aggregates, has been continuously improved. At present, crushing and screening plants at home and abroad are developing in the direction of large-scale, intelligent and environmentally friendly. The application of new high-efficiency crushers and multi-layer vibrating screens has significantly improved production efficiency and finished product quality. At the same time, the tightening of environmental protection policies has prompted enterprises to adopt closed plant buildings and dust removal and noise reduction technologies to reduce dust and noise pollution.

In terms of crushing and screening processes, typical processes include coarse crushing, medium crushing, fine crushing and screening. After the raw materials are coarsely crushed by a jaw crusher or a gyratory crusher, they are medium and finely crushed by a cone crusher or an impact crusher, and finally graded by particle size through a vibrating screen to form finished aggregates of different specifications. Some high-end production lines also introduce closed-loop circulation systems to return substandard materials to the crusher for reprocessing to improve resource utilization.

In terms of equipment configuration, the crushing and screening plant needs to select the appropriate equipment combination according to the hardness of the raw materials, production capacity requirements and finished product specifications. For example, the crushing of hard rocks such as granite usually adopts the hard rock solution of “jaw crusher + cone crusher + vertical shaft impact crusher”, while medium-hard materials such as limestone can adopt the simplified process of “impact crusher + vibrating screen”. In addition, the intelligent control system can monitor the operating status of the equipment in real time, optimize production parameters, and reduce energy consumption and maintenance costs.

In the future, with the integration of technologies such as 5G and the Internet of Things, the crushing and screening plant will further realize automation and digital operation, and promote the industry to develop in the direction of high efficiency, energy saving, green and sustainable development.
