Gravity sorting machine for waste circuit board recycling production line

The specific gravity separator is a new type of sorting and separation equipment newly introduced by our company. It is also a new environmentally friendly and energy-saving equipment in the current mixture separation and sorting industry. The equipment has stable performance, obvious effect, high efficiency and energy saving, environmental protection standards for the use site, no water pollution, no acid and alkali pollution, and the products are favored by customers after they are listed. The specific gravity separator has a wide range of uses and is suitable for the separation and sorting of various metal and non-metallic materials, powdery materials, granular materials, and mixed materials using different materials, different specific gravity, and different particle sizes. , chemical industry, electronic metal recovery and rare metal recovery and many other industries have very broad prospects for use. It replaces the old equipment that pollutes and wastes resources, such as the old process water separation and flotation in the old market.

It has the characteristics of short process flow, convenient operation, no pollution, low energy consumption, low cost and strong adaptability; it can handle high and low content of electronic waste waste; simple equipment, low investment, easy to realize continuous industrial production; metal recycling If the unique gold and platinum purifying agent in this technology is used, its purity and recovery rate can reach 100%, and the waste slag after e-waste extraction can be mixed with sand and gravel in a certain proportion to make slag bricks, which will become high-quality slag bricks. Wall building materials, or powder made from PCB boards to make handicrafts, no solid waste discharge. Traditional electronic waste treatment has caused a large amount of pollutant discharge. Using this process to extract gold not only protects the environment, but also has good economic benefits, benefiting the country and the people, and killing two birds with one stone. This method is especially suitable for small and medium-sized enterprises and individual practitioners.

The specific gravity separator, pulse dust collector and induced draft fan form a set of grading system. The oil and paper are pumped away by the material under the action of the fan, and the coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating grading turbine. The coarse particles are collected by the gravity and centrifugal force, and are thrown around the cylinder by the rotor blades and slide down the cylinder. It is blown to the classification chamber again, and the material is discharged from the lower discharge port under the action of gravity.

The utilization value of secondary resources of precious metals is increasing, mainly because humans have produced a large amount of precious metals (gold, silver, platinum, palladium, rhodium, iridium). Precious metal resources are scarce, especially gold and silver industry reserves are less. The content of precious metals is much higher than that of the original ore, generally hundreds of times more. Gold production, consumption and main application areas. The gold content in e-waste is much higher than that of the original ore, generally hundreds of times more. The recovery from it is much lower than the extraction cost from the original ore, and the economic benefit is very obvious. The grade of electronic waste waste generally ranges from 800 to 1500 grams per ton, that is, 0.8 to 1.5 grams of gold can be extracted per kilogram of waste.
