Reasonable and scientific crushing and recycling of waste tires is one of the main ways of recycling and comprehensive utilization of waste tires. At present, most of the waste truck and bus tires of all-steel tires and natural rubber in the industry are processed by retreading and producing recycled rubber and rubber powder.

Among them, according to the particle size, part of the recycled rubber powder is used to produce recycled rubber, and the other part is used to produce products such as modified asphalt or waterproofing membranes. So what equipment is needed for the recycling of these waste tires?

Waste tire recycling equipment generally refers to shredding equipment, which shreds tires into rubber powder, such as equipment for separating steel wires, tire ring cutting machine, tire slicing machine, tire smashing machine, steel wire separator, crushing unit, tire bilateral cutting machine, Steel ring separator, shredder, glue breaking unit, etc.

Waste tire processing equipment is divided into two production lines, with different equipment. Semi-automatic waste tire rubber powder equipment is composed of ring cutter, strip cutter, dicing machine, wire mill, conveyor, waste tire grinding unit, fiber separator and dust removal facility. The automatic tire grinding machine consists of wire drawing machine, Shredder, conveyor, feeding rotary system, double-roll rubber powder machine, steel wire magnetic separator, magnetic separation separator, pulse dust collector, customers can use these two specifications of waste tire processing equipment according to different raw materials In the line, choose to match with different stand-alone devices.

The main working steps are as follows: firstly remove the ring steel wire, then shred it with a shredder, separate the fine steel wire with a wire separator, obtain granules by a rubber granulator, and re-grind as needed to obtain rubber powder. In the middle, dust removal can be added to prevent pollution, and the fiber in the tire can be removed by the fiber separator, and the obtained purity is higher.

The above is the relevant introduction about waste tire recycling. When choosing to purchase tire recycling equipment, you should fully understand your own needs, such as output, environmental protection, etc., and then choose the appropriate waste tire recycling equipment.

What are the most viable markets in the local geographic area? Which markets can be developed quickly? (Typically, it is tire-derived fuel and civil engineering). Does the local/state/federal government have a grant program for market development? A critical element in examining potential markets is determining the obstacles to these markets? Below is a quick view of possible obstacles (by market) for consideration.

Obstacles to Tire Derived Fuel

Fuel Types/Supply
What other supplemental fuels are currently used in the target market? What type of fuels is the target industry currently using? If pulverized coal is the dominant fuel then TDF may not be a good fit. How many tires are available in the local market area? For example in the case of TDF, the target client may require one to three million scrap tires per year. Will the proposed business be capable of providing this amount of tires to the target client?

Acceptance of TDF
Who will be the sole responsible party for convincing management (end user) to begin using TDF? If so, how much is the target client paying for their main fuel supply? TDF will always have to be lower. Is the facility being paid to take any materials for fuel? If so, TDF typically cannot compete. Will the target client have to make substantial modifications to their existing operations to incorporate TDF? If so, who will pay for this modification (industry, government subsidy)? The acceptance of TDF can be a function of the feeding/monitoring system required. Most facilities do not have capital expenses calculated into their budget. Waiting for this expense to be budgeted can take two years. How long will it take for you and the target industry to obtain permits?

Opposition to TDF
Will opposition come from public concerns or competition? Is the facility in a nonattainment area for any regulated air pollutants? If so, what are the main emission criteria considerations? Compare those to the benefits of TDF, which has been found to lower nitrogen oxides.

Obstacles to Rubber Modified Asphalt
Is there a mix of roadway pavements in target market area (construction material, road surface material/style)? Have you determined the receptivity of the local department of transportation, public works departments and contractors for utilizing alternative pavements? The history of alternative pavements in the target market, the region and state will be a critical issue. The time lag between the initial contact with a potential user and sale of a pavement product could be as long as three to four years.

What about the supply of quality ground rubber? Can you provide this material? What other types of modifiers are the local roadway contractors using? What about the cost competitiveness of ground rubber versus other modifiers? Remember, quality and consistency of the ground rubber will be of paramount importance.

Obstacles to Civil Engineering Applications
Check with local regulations to determine the classification of a processed tire. Is it considered a solid waste or a beneficial use commodity? Do the present rules make it conducive for a smooth entry into the market? Have you determined the receptivity of the local departments of solid waste, water quality and health to the proposed civil engineering applications? What about state agencies? Have these applications been tested in the local target market area? If used previously, what were the results?

Standard Practice for the Use of Scrap Tires in Civil Engineering Applications:
This American Society for Testing and Materials (ASTM) publication provides guidance for testing the physical properties and data for assessment of the leachate generation potential of processed or whole scrap tires in lieu of conventional civil engineering materials, such as stone, gravel, soil, sand or other fill materials. In addition, typical construction practices are outlined. This ASTM document (D--98) is available from the Rubber Manufacturers Association please see https://www.ustires.org/
