When is a tire too worn to drive on safely? Tires should be changed when the tread is worn down to 2/32&#; and the tire no longer provides good traction while driving. At this point, the tire is no longer useful for its intended purpose. However, most of the product is still intact. Most of the rubber, metal, and nylon used to manufacture the tire are still there.

As these substances are, for the most, not biodegradable, it is a shame when they find their way into landfills. Thus, the need for tire recycling equipment. Tire shredders are capable of removing and separating out the different tire components for recycling and reuse.

Tire shredders are some of the most hard-working and robust equipment. Cutting through large truck and even mining tires, however, requires immense amounts of power and torque. The shredding process also creates a lot of wear and tear on the machine&#;s blades as they cut through thick rubber and metal. To make tire recycling a profitable business, recyclers must invest in high-quality machines that can be serviced quickly and easily.

Primary Shredder

The primary shredder is usually the first piece of equipment in any recycling line. This first step is where the whole tire is broken down into more manageable sizes. When recycling extremely large tires, such as those used in mining operations, you may choose to start by running the tires through a machine to remove the tire&#;s wire bead. This precursory step makes the rest of the shredding process easier and will help the blades last longer.

Made in both single and double shaft configurations, primary shredders make quick work of the whole tires. They can process anywhere from 10-30 tons of rubber per hour. The advantage of a single shaft shredder is that the product is usually more uniform. Single shaft shredder output can be screened. Large rubber pieces get filtered out by the screen before taking a second pass through the shredder.

Having double the shafts, however, can significantly speed up the shredding process. While double shaft shredders typically are not screened and produce shreds in the broader array of sizes, lack of uniformity may not be a problem if your primary product is crumb rubber. These machines are great at breaking down tires fast.

Grater

Also known as the secondary shredder in many lines, graters process the rough shreds produced by the primary shredder into rubber pieces one inch or smaller in size. Adding a screen to the grater is a common way to control for particle size. It is at this step in the process that the tire wire is also removed. This wire is hard on the blades of any piece of equipment and can be easily recycled with other scrap metal. Removing it at this stage makes the rest of the process down the line run more smoothly. When the rubber exits the grater, it is uniform, wire-free mulch, which is a desirable end market product for many uses in and of itself.

Granulator

Some waste rubber recycling projects require crumb rubber, which consists of rubber granules smaller than a tire grater can produce. To produce crumb rubber, recyclers feed clean rubber mulch into the granulator. Making high-quality crumb rubber may require several passes through the machine. As it is ground to particles only 3/8&#; in size, any remaining contaminants are also removed. A high-grade finished product should be nearly 100% free of wire, nylon, or polyester. Only clean crumb rubber will have the desired properties when mixed with asphalt or other building materials.

Cracker Mill

If rubber powder is the end product for your business, you will need a cracker mill. This piece of machinery takes an input of crumb rubber and grinds it down to a powder so fine that it is measured in millimeters. This fine-textured product is small enough to be used in manufacturing products requiring rubber-like properties, including car parts, membranes, and even new tires. The technology and applications for powder rubber continue to improve and expand.

Tire shredding equipment is a powerful lineup of machines that regularly break down some of the most rigid recycling material. With each step in the line, the tires are broken down into smaller and smaller pieces.

The rubber produced at nearly every stage by each machine is useful to someone in some application. The trick is to understand the market and your customers. Know what people are using in your area and find the machine that will make that product.

Tire shredder manufacturers continue to look for ways to improve their machinery, as well as looking for ways to expand the use of their workhorses into other recycling sectors. The health of our environment depends on this important work.

A tire shredder is an essential piece of equipment in the tire recycling process that can cut tires into smaller pieces, making them easier to process and recycle. In this article, we will take an in-depth look at tire shredders, how they work and what they are used for in various applications.

Tire shredders are heavy-duty machines designed to process the solid material components of tires, such as the rubber, wire and synthetic fibers inside the tire. The powerful blades of a tire shredder cut tires into smaller pieces, typically ranging in size from 2 inches (50 mm) to 6 inches (150 mm). The size of the output can be adjusted according to the requirements of subsequent processing steps.

Tire shredders are typically built with a twin-shaft configuration, which is more conducive to the shredding of tires. The twin-shaft shredder is usually used for primary shredding. Pelletizers are used for further size reduction after primary shredding.

Tire shredder working principle

Feeding: The tires are fed into the shredder via a conveyor belt or automatic conveyor system.

Shredding: The shredder uses a set of rotating blades to cut the tires into small pieces. The blades are powered by an electric motor and are mounted on a high-speed rotating shaft. As tires are fed into the shredder, they are cut by the rotating blades.

Discharge: The shredded material is then discharged from the shredder through the discharge opening. There is a metal screen installed at the discharge opening, the rubber pieces that meet the size are excluded through the screen, and the rubber pieces that do not meet the size or are too big will enter the shredder again to be shredded until they meet the size.

The output size can be controlled by adjusting the speed of the blade, the size of the blade or the size of the screen in the shredder.

Advantages of Tire Shredder

Waste Tire Disposal: Tire shredders can effectively shred and process waste tires, converting them into reusable materials. This helps to solve the environmental problems of waste tire treatment and disposal.

Resource Recycling: Shredded tires can be used for recycling. For example, shredded rubber granules can be used to make new tires, rubber flooring, rubber fenders and other products. This helps to conserve resources and reduce the need for raw materials.

Space Saving: Used tires usually take up a lot of storage space. By using a tire shredder, tires can be effectively reduced in size, thus saving storage and transportation space.

Energy Recovery: Some advanced tire shredders can also shred tires into fuel pellets for energy recovery. These pellets can be used to generate electricity or heating systems, providing renewable energy.

Increased Efficiency: Tire shredders can efficiently process large quantities of scrap tires, increasing processing speed and efficiency. This is important for industries such as waste tire processing plants and recycled rubber manufacturers.

In short, tire shredders are essential machines in the tire recycling process. They are designed to process the tough material components of tires, cutting them into smaller pieces for further processing or use in various applications. The use of tire shredders helps in the recycling of used tires and provides an environmentally friendly solution to the problem of tire waste.
