Integral dry sand making system

Abstract

The invention discloses an integral dry sand making system. The system is structurally characterized in that the lower part of a bucket elevator is connected with a feeding rubber belt machine, and the upper part of the bucket elevator is connected with a high-frequency screen feeding chute; the high-frequency screen feeding chute is connected with a high-frequency screen; the lower part of the high-frequency screen is connected with a high-frequency screen front discharging chute and a rainscreen type powder selecting device; the high-frequency screen front discharging chute is connected witha double-cavity vertical shaft crusher; the upper end of the rainscreen type powder selecting device is connected with a dust collecting air pipe, and the dust collecting air pipe is connected with adust removal device; the lower end of the rainscreen type powder selecting device is respectively connected with an undersize powder selecting fan and a humidifier feeding chute; the humidifier feeding chute is connected with a humidifier; and the double-cavity vertical shaft crusher is connected with the feeding rubber belt machine. The integral dry sand making system has the following beneficial effects that according to the design, the high-frequency screen is adopted for screening, and the high-frequency screen has the characteristic that a frame cannot vibrate and a screen vibrates, so that the influence on the sand making system is reduced, and high-efficiency powder selection is achieved while the screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sand making process, in particular to an integrated dry sand making system. Background technique [0002] In recent years, with the depletion and prohibition of mining of natural sand, environmental protection requirements have become more and more stringent. Machine-made sand, which was originally used in large quantities in the fields of hydropower, nuclear power, road and bridge engineering construction, is gradually becoming popular. The demand for machine-made sand for concrete and dry-mixed mortar is increasing year by year. At present, many equipment manufacturers have introduced dry sand-making systems. These complete sets of equipment often have the advantages of environmental protection, high-quality finished sand, and recyclable stone powder. But the core Advanced crushing, screening and powder selection equipment have not been able to achieve major breakthroughs, and most of the sand making s...

Problems solved by technology

[0003] The purpose of the present invention is to provide an integral dry sand making system. This new type of sand making building can well solve the problem that the traditional sand making building system uses ordinary vertical shafts and air selection screens for crushing and screening. The output and reliability are low. The problem
