Embodiment 1

[0024] A construction waste crushing system, including a feeder, a head crusher, a first conveyor belt, a sand making machine, a second conveyor belt, a magnetic separation device, and a vibrating screen connected in sequence. The discharge end of the vibrating screen is connected with several The crushed aggregate conveyor belt is used to transport the crushed aggregate; the other end of the crushed aggregate conveyor belt connected to the uppermost discharge port of the vibrating screen is connected to the winnowing equipment for discharging white garbage or paper scraps, and the output of the winnowing equipment One end is connected with a conveying return belt, and the other end of the conveying return belt is connected with the feeding end of the sand making machine.

[0025] After the construction waste is initially crushed by the head crusher, the sand making machine can grind the crushed materials into smaller particles, and the vibrating screen can directly screen the ...

Embodiment 2

[0028] On the basis of Example 1, the discharge end of the vibrating screen includes four discharge ports, and the aggregate particle sizes of the discharge ports from bottom to top are: below 3 mm, 3 mm to 10 mm, 10 mm to 30 mm, and 30 mm above.

[0029] The discharge end of the vibrating screen includes four discharge ports, so aggregates of different particle sizes can be screened accurately, which facilitates the collection of aggregates of different specifications and improves the utilization rate of products. Below 3mm, 3mm~10mm, and 10mm~30mm can be recycled separately to obtain products of different specifications. Larger aggregates over 30mm will be transported to the air separation equipment together with white garbage and paper scraps, and then transported to the feeding end of the sand making machine through the conveyor belt, then the aggregates over 30mm can be crushed again, making the aggregate be fully utilized.

Embodiment 3

[0031] On the basis of Embodiment 1 or Embodiment 2, the lengths of the first conveyor belt, the second conveyor belt, the pulverized aggregate conveyor belt, and the conveying return belt are all 6m to 8m. The width of the conveyor belt, crushed aggregate conveyor belt, and conveying return belt is 60cm to 80cm.

[0032] The length of the first conveyor belt, the second conveyor belt, the crushed aggregate conveyor belt, and the conveying return belt are all 6m-8m and the width is 60cm-80cm, so as to ensure that the materials can be accurately conveyed and avoid material leakage from the conveyor belt.

Abstract

The invention relates to the field of construction waste recycled aggregate production, in particular to a construction waste smashing system. The technical scheme of the system is that: the construction waste smashing system comprises a feeding machine, a head crusher, a first conveyer belt, a sand making machine, a second conveyer belt, magnetic separation equipment and a vibrating screen, the discharge end of the vibrating screen is connected with a plurality of smashed aggregate conveyer belts for conveying smashed aggregate; the other end of the smashed aggregate conveyer belt, which is connected with the discharge hole in the uppermost end of the vibrating screen, is connected with air separation equipment for discharging white rubbish or scraps of paper, the discharge end of the airseparation equipment is connected with a material conveying and back feeding belt, and the other end of the material conveying and back feeding belt is connected with the feed end of the sand makingmachine. The construction waste smashing system provided by the invention can be used for efficiently screening aggregate and reducing aggregate waste, and the problems that a current construction waste smashing device is low in efficiency and has difficulty in fully recycling the aggregate.

Description

technical field [0001] The invention relates to the field of construction waste recycled aggregate production, in particular to a construction waste crushing system. Background technique [0002] As one of the pillar industries of the national economy, the construction industry has developed by leaps and bounds in recent years, but the resulting construction waste is also increasing. According to incomplete statistics, my country produces 200 million tons of construction waste every year, especially in the disaster-stricken areas after the earthquake. A large amount of collapsed construction waste, the above-mentioned construction waste not only causes a large amount of waste of resources, but also takes up a lot of space, affects the urban environment, and brings many inconveniences to people's production and life. [0003] The utility model patent with the patent application number CN200920032757.3 discloses a production equipment for construction waste recycled aggregates,...
