Tire refining is fuel oil. The main substances in the raw materials that make up waste tires are rubber, carbon black, special additives, steel wire, polymers and other chemical substances. Therefore, waste tires are obtained after pyrolysis in waste tire refining equipment. The product is fuel. Waste tire refining is a legal refining project. Tire oil is also used for regular purposes. As for unenvironmental refineries that cause serious pollution to environmental protection, they are not allowed to produce because they are not environmentally friendly and do not have relevant environmental assessments. The density of the oil refined by the waste tire refining equipment is about 0.93, and the calorific value is close to 10,000 kcal. It is mainly sold to cement plants, glass plants, ceramic plants, power plants, steel plants, and boiler plants.
Waste tire oil refining equipment is divided into batch type and continuous type. In the whole tire refining site, intermittent refining equipment is generally used. Following the changes in environmental protection requirements and policies, more places are to use continuous equipment. Continuous refining equipment has greater advantages. Continuous refining equipment feeds and discharges slag in a confined space. The production is safer and more environmentally friendly, and the investment is higher.
The following figure shows the difference between Copers continuous and intermittent tire refining equipment?
| Continuous Pyrolysis Technology | Batch Pyrolysis Technology | |
| Process Route | Realizing continuous performance operation under the premise of safety and environmental protection. | Intermittent work, there are safety and environmental risks. |
| Throughput | Single machine with large capacity, 20-30tons per day, high operating efficiency | Single machine is small, 8-10 tons per day, low operating efficiency |
| Automaticity | Intelligent control, less labor, low labor intensity. | Manual or semi-automatic, high labor intensity. |
| Fuel Consumption | The combustible gas produced by pyrolysis can be used 100% and 70% fuel can be saved. | Additional fuel consumption is required, and the gas produced cannot be completely recycled. |
| Benefit comparison | The initial investment is large, but it is a one-time investment, and the return cycle is faster and the life cycle is longer. High oil yield, good quality oil and good economic benefit. | Early investment is little, but lower oil yield , poor quality, poor economic benefit. |
| Market Prospects | The government encourages the direction of development. | Phased out due to safety and environmental risks. |
| Heating Time | Saving heating time | Long heating time. |
| Slag | High temperature full close discharger slag, safe and environmental protection, short time. | The pyrolysis furnace needs to be cooled down, the waiting time is long, and there are safety risks |
| Feeding | Automatic feeding system, fast feeding, save labor. | Manual feeding, slow speed. |
