摘要
The present invention relates to a process for recycling waste toner with an additive and a mixture resulting from the recycling of waste toners. Waste toners are a type of waste that contains materials such as (non) metals, plastic, but also toner powder that is not consumed in the containers. To date, this powder has not been used because of the high risk of explosion during processing. This invention encompasses the process of recycling waste toners (1) in a way that they are dozed to device for mechanical shredding (3) with the adding of the additive (2) which is by its composition Calcium carbonate - calcite - CaCO3 CAS number 471-34-1, in the amount of 5-12% of the total mass of waste toners all in the normal atmosphere. After the mechanical shredding (3), the mixed shredded part of the waste toner and the additive (2) are sifted (4) through the sieve. Resulting waste powder contains mass part of Calcium 3-35% and mass part of TOC* 6-40% powder particle size 500 μm The recycling process which is the subject of this invention allows the mechanical shredding to happen in the open atmosphere without the risk of explosion due to adding the additive calcite. *TOC - total organic carbon - total carbon
