At the same time, the concrete industry's demand for aggregates such as sand and gravel is increasing, and the impact of the consumption and mining of natural sand and gravel on the ecological environment is becoming increasingly serious. If construction waste is processed and made into recycled aggregates for secondary use, it will be of great significance to environmental protection and resource utilization.

[0003] The recycled aggregate formed after the crushing of construction waste has many pores and tiny cracks, and has the characteristics of low apparent density and high water absorption, which has an adverse effect on secondary use. Therefore, the strengthening of recycled aggregate is one of the main research contents of the current construction waste recycling. A large amount of dust will be generated in the process of strengthening the recycled aggregate to remove the adhesive mortar. Stopping the machine for manual cleaning will affect production efficiency and is not good for the health of operators.

[0037] The working process of the utility model is:

[0038] 1. Before using the device, you should select the appropriate grinding cylinder bottom 13 and the particle collection drawer sieve bottom 13' according to the aggregate reinforcement particle size requirements. Generally, after the grinding cylinder bottom 13 is determined according to the aggregate reinforcement particle size requirements, the particle collection drawer sieve bottom 13' with a smaller aperture is selected;

[0039] 2. Open the barrel bottom buckle 15, pull the barrel bottom handle 17, take out the grinding barrel bottom 13 used last time, and then install the selected grinding barrel bottom 13 through the barrel bottom slide 14, and fix it through the barrel bottom buckle 15 and the barrel bottom slot 16;

[0040] 3. Open the pellet collection drawer buckle 21, pull the handle 19, pull out the pellet collection drawer 18, take out the pellet collection drawer sieve bottom 13' used last time, put in the pellet collection drawer sieve bottom 13' selected for this use, push the pellet collection drawer 18 in through the pellet collection drawer slide 20, and fix it through the pellet collection drawer buckle 21 and the pellet collection drawer slot 22;

[0041] 4. Add the aggregate to be reinforced through the feed hopper 6. Note that the amount of aggregate added should meet the equipment use requirements;

[0042] 5. According to the aggregate strengthening particle size requirements, select the appropriate speed and start the drive motor 7;

[0043] 6. As the motor 7 rotates, the grinding roller 10 and the cleaning scraper 12 rotate accordingly; the grinding roller 10 strengthens the aggregate added into the grinding cylinder 1, and the cleaning scraper 12 cleans the side wall of the grinding cylinder 1 and promotes the rotation of the aggregate in the grinding cylinder 1, thereby improving the aggregate strengthening efficiency;

[0044] 7. When part of the aggregate reaches the required particle size for strengthening, it will fall into the aggregate collection drawer 18 through the sieve hole 13-1 of the grinding cylinder bottom 13, and at the same time, the fine powder with a smaller particle size will also enter the collection drawer 18;

[0045] 8. The vibrations generated by the operation of the machine and the falling of the pellets will cause the spring 23 to expand and contract, so that the pellet collection outer trough 24 will be displaced along the pellet collection outer trough slide 25, and the pellet collection drawer 18 will also be displaced, thereby playing a screening role. The fine powder with a smaller particle size passes through the sieve hole 13-1 of the sieve bottom 13' of the pellet collection drawer and falls into the fine powder collection drawer 26;

[0046] 9. When the motor rotation time is over, turn off the motor power supply, and observe the grinding of aggregate in the grinding cylinder 1 through the magnetic door 5 to decide whether to set the grinding time again. If the grinding is completed, proceed to the next step;

[0047] 10. Open the granular material collection drawer buckle 21, pull the granular material collection drawer handle 19, and draw out the granular material collection drawer 18. After collecting the reinforced aggregate, the granular material collection drawer sieve bottom 13' can be taken out and placed in the sieve bottom storage bin 33, and the granular material collection drawer 18 can be pushed back into the main body of the grinding cylinder 1;

[0048] 11. Open the micro-powder collecting drawer buckle 29, pull the micro-powder collecting drawer handle 27, draw out the micro-powder collecting drawer 26, clean the micro-powder generated by the reinforced aggregate, and then push the micro-powder collecting drawer 26 back into the main body of the grinding cylinder 1;

[0049] 12. The cylinder bottom buckle 15 can be opened, and the grinding cylinder bottom 13 can be pulled out through the cylinder bottom handle 17 and stored in the screen bottom storage bin 33.
