Abstract

The invention discloses a dry machine-made sand production system, which comprises a crusher, a vibrating feeding mechanism and a winnowing screening device, which are sequentially connected with one another, wherein a dust outlet of the winnowing screening device is connected with an inlet of primary dust-removing equipment; an air outlet of the dust-removing equipment is connected with the inlet of a draught fan; an outlet of the draught fan is respectively connected with an air inlet of the winnowing screening device and the inlet of secondary dust-removing equipment; a crude product outlet of the winnowing screening device is connected with the inlet of the crusher; a dust outlet and a feeding opening are formed in the upper part of the winnowing screening device; a lateral air inlet is formed below the feeding opening; a sieve is arranged in the middle of the winnowing screening device; a finished product outlet below the sieve and a crude product outlet below the outlet at the lower end of the sieve are formed in the lower part of the winnowing screening device; and the feeding opening is connected with a discharge opening of the vibrating feeding mechanism. According to the dry machine-made sand production system, the energy consumption of the system is effectively reduced; and the equipment investment cost and the late maintenance cost are greatly reduced.

Description

technical field [0001] The invention relates to the field of machine-made sand production, in particular to a dry machine-made sand production system. Background technique [0002] With the improvement of people's awareness of environmental protection and in order to reduce the damage to natural resources, the use of natural sand has been strictly restricted, and it will gradually withdraw from the building materials market and be replaced by machine-made sand. Machine-made sand belongs to the fine aggregate in concrete, which refers to rock particles crushed by machinery with a particle size of less than 4.75mm. At present, the commonly used method of dry machine-made sand is: after the raw material passes through the crushing equipment, the finished product is screened out, usually with additional shaping and humidification processes, and at the same time, all or part of the coarse material above the finished product size is returned to the crushing equipment for re-crushi...
