Abstract

The invention discloses a compound screening device for desert sand, which relates to the technical field of sand material screening, and comprises a primary centrifugal screening component and a secondary blast screening connected to the outlet of the primary centrifugal screening component component and the secondary centrifugal screening component; the primary centrifugal screening component coarsely screens the desert sand, firstly separates the large particle size and small particle size desert sand, and the coarsely screened desert sand passes through the secondary blast The screening component and the secondary centrifugal screening component carry out fine screening, and finally separate several kinds of sand materials with different particle sizes from large to small, so that the final obtained different sand materials can be used in different ways. This device is dedicated For the separation of desert sand, the separation of desert sand is relatively sufficient, and the use value of desert sand will not be affected by screening.

Description

technical field [0001] The invention relates to the technical field of sand screening, in particular to a compound screening device for desert sand. Background technique [0002] At present, the sand used in construction projects in most areas of my country is still river sand. Due to the increase in demand, river sand has been over-exploited for many years. Now my country's desertified land has reached 18.12% of the country's land area, about 1.7 million square kilometers. In areas rich in desert sand resources, there are a large number of ultra-fine sand resources. In order to meet the requirements of sustainable development and environmental protection, desert sand is used in construction. profound significance in the industry. However, the average particle size of desert sand is small, usually between 0.13mm and 0.315mm, and the roundness is low, so it needs to be screened to select sand particles that meet the requirements of concrete preparation. [0003] The commonly...
