Plastic Recycling for Household Appliances and Sundries

Design Conditions

1.Raw materials: shredded into 50-70mm pieces and use packaging bags.

2.Raw materials identified; PP-PSABS-Metal-Odor A, etc.

3.The highest capacity of shredder will be 2t/h when the fraction around 20mm, blade change 10h.

4.Power supply: 380V/50HZ.

Description Of The Sinking And Floating Process

When the customer uses the forklift to pour the raw material into the feeder, the raw material enters the 15 degree salt water tank the metal will sink to the bottom and carried to big bag by the screw, the silica gel, PP, PS, ABS sponges float up in the 15 degree salt water , the sponge sucked by suction device to absorb the bagging, and the rest will be screwed into the shredder and shredded in to 20mm fraction, and the spiral will be transported to the high-speed friction machine to clean the coating and dirt, After washing and de-watering process, it enters the 15-degree water tank to remove the metal odor The floating material enters the dehydrator to remove the salt water and then enters the clean water tank. The bottom material comes out of PS and ABS, and the floating material comes out of PP bagging for next electrostatic color sorting.

Process Specification

This recycling system is used to sort sundries, E-waste, battery shells, ELV plastics and iron plant ASR. With the development of the plastic industry and the improvement of people's awareness of environmental protection, it is urgent to recycle waste plastics. The demand for engineering plastics in the plastic recycling industry is also increasing. The plastic recycling line effectively solves the problem of waste plastic that is difficult to be treated by sinking and floating iron removal, crushing, grinding, sorting, cleaning, de-watering, static electricity, color sorting and other processes.

Features

1.The recycling and cleaning line integrate humanization and automation to save labor.

2.High quality VFD will used in the key part of electrical control for easy speed adjust and reliable operation.

3.The whole system will take manually control for starting, brake, operation, alarm etc.... the advantage is stable operation and easy to shift order and reduce the size of electrical carbine.

4.Less than 10t/h water consumption (need clean water supply, closed loop water circle will save total cost at most.) All of the water could be recycled if take the central water treatment; solid suspend less than 1500mg/l without odour.

5.The installed power depends on the capacity.

6.Compressed air: 0.6-0.8MPa.

7.Noise Level: the shredder area with level 130-135dB, de-water noise level 90-105dB.
