Crumb Rubber Powder 30-Mesh
Crumb rubber with a 30 mesh size falls within the medium-fine range of crumb rubber.
It consists of small, granular pieces of recycled tire tread, with a particle size around 600 microns (0.6 millimeters).
Process:
Similar to other crumb rubber sizes, there are two main production methods:
Ambient Mechanical Grinding:
This is the most likely method for 30 mesh crumb.
- Scrap tires are shredded into chips.
- Metal and fibers are removed using magnets and air separation systems.
- The rubber crumb is then ground in mills. The number of grinding passes may be more than for coarser crumb sizes but less than for very fine grades.
- Screens or air classifiers separate the crumb into different sizes, isolating the 30 mesh fraction.
However, for 30 mesh, mechanical grinding is typically sufficient and more economical.
Technical Specifications:
Mesh Size: 30-Mesh
Particle Size: Approximately 600 microns (0.6 millimeters)
Fineness: Medium-fine
Other Specifications (may vary depending on supplier):
Moisture content: Typically, less than 0.2%
Ash content: Typically, less than 10%
Material: Recycled tire rubber (can be natural or synthetic)
Uses:
The medium-fine size of 30 mesh crumb rubber makes it suitable for applications requiring a balance between several factors:
Drainage: Offers good drainage properties due to the particle size.
Surface Properties: Provides a somewhat smoother surface compared to coarser crumb, making it suitable for some applications where a finer feel is desired.
Performance Enhancement: Can be used to improve specific properties in various products.
Here are some common uses of 30 mesh crumb rubber:
Playground Surfaces: Can be used as a top layer on playgrounds, offering a balance between a cushioned yet somewhat smoother feel compared to larger crumb.
Athletic Tracks: Used as a component in athletic track underlayment, providing drainage and stability.
Rubberized Products: Can be used as a filler in rubberized products like molded mats or tiles, offering improved strength, flexibility, and impact resistance.
Construction Applications: In some cases, it might be used in specific construction projects for drainage or as a lightweight fill with some structural integrity.
Additional Points:
- 30 mesh crumb rubber is an environmentally friendly product utilizing recycled tires.
- The specific properties can be tailored depending on processing methods and additives used.
- Proper handling is crucial due to potential dust inhalation hazards.
