Solar PV Panel Recycling Machine

Products Detail

Waste photovoltaic panel recycling equipment, first through automated dismantling equipment. The junction box is disassembled and then its aluminium frame is removed. Then the glass in the panel is removed by the glass removal machine. Remove the tempered glass. Immediately after that, the battery is crushed and sorted. Extract high value silicon powder, copper powder, plastic, aluminium frame, junction box, etc. The main components of photovoltaic panel module: aluminium frame, glass, battery panel, EVA adhesive, junction box and so on. The main component of glass is silicon dioxide, and the secondary components are: alumina, limestone, soda ash, etc. EVA is mainly ethylene-vinyl acetate copolymer. The panel components are monocrystalline and polycrystalline silicon. The frame is mainly made of aluminium. The backsheet is made of two layers of PVF film and one layer of PET film. After the photovoltaic panel recycling equipment to extract the metal in it. So that the resource recycling. The comprehensive recycling rate of the whole set of equipment is more than 96%. The proportion of glass is 65%~70%, and the proportion of aluminium frame is 10%~15%. Plastic is about: 10%, 3%~5% silicon. The recycled materials can be used in different industry sectors. Glass can be sent to glass manufacturing plants after recycling. Aluminium frames are sent to aluminium refineries. Waste plastics can be used as fuel. Silicon can be reused in the heavy metal industry. Separated copper powder can be used for copper refining.  

Principle of operation: The junction boxes and aluminium frames of the PV panels are first removed from the solar PV panels using an automatic frame remover. This facilitates subsequent processing and recycling. After removing the frames, the PV panels are sent to the preheating area. The glass panels are baked by heating tubes. The EVA film is softened and dissolved. This facilitates the subsequent peeling of the glass from the backsheet. After preheating, the PV panels are automatically transported to the de-glazing machine. The photovoltaic glass panels are squeezed between two rollers. This moves the glass forward. Under mechanical action. The cutter breaks the glass panels for separation. The separated glass is collected in tonne packs through the glass outlet. The panels are transported by conveyor to the next process. The battery plate enters the crushing and sorting system immediately after. Firstly, the battery boards are shredded into small pieces of 3-4cm. Then it passes through the crusher, where the blades hit at high speed to break up the crushed materials. Equipped with 2mm screen. The material then passes through the analyser for gravity sorting. Through the granularity of the materials in line with the specific gravity sorting machine for sorting. The materials that do not meet the particle size will enter the grinding system. After screening and grinding, the particles are screened again by the specific gravity separator. The heavier metal powder copper is discharged from the front discharge port. The lighter metal and plastic mixed powder is discharged from the rear outlet. The mixed metal and plastic powder then passes through the high-pressure electrostatic separator, sieving out: plastic and metal powder.
