Rubber Screen Panel vsPolyurethane Screen Panel: a comprehensive comparison of materials, performance and application scenarios
Rubber Screen Panel vsPolyurethane Screen Panel
a comprehensive comparison of materials, performance and application scenarios
1. Material and structure comparison
|
Comparison dimensions |
Polyurethane screen plate |
|
|
Basic materials |
Mainly made of natural/synthetic rubber (nitrile, chloroprene rubber), bonded with metal frame |
Polyurethane elastomer as the core, can be combined with metal frame |
|
Structural characteristics |
Strong elasticity, low rigidity, less modular design, light weight (about 15kg/㎡) |
Adjustable hardness (Shore 20A-95A), compact structure, similar weight but more solid |
|
Applicable scenarios |
Small and medium-sized vibrating screens, high-frequency vibration equipment |
Large screening equipment, heavy vibrating screen (such as relaxation screen) |
2. Core performance differences
1. Wear resistance
Rubber Screen Panel: suitable for medium hardness materials (raw coal, sand and gravel), with a service life of 3-6 months; easy to wear under high hardness ores (iron ore).
Polyurethane screen plate: wear resistance is 3-5 times that of rubber, with a service life of 6-12 months, suitable for high impact materials (gold mines, copper mines).
2. Impact resistance and elasticity
Rubber Screen Panel: excellent elasticity, absorbs high-frequency vibrations, but long-term impact is prone to tearing and delamination.
Polyurethane screen plate: higher tear strength (30-60kN/m), suitable for large particle screening, stable impact resistance.
3. Corrosion resistance and weather resistance
Rubber Screen Panel: general acid and alkali resistance, synthetic rubber temperature resistance -30℃~80℃, easy to age.
Polyurethane screen plate: excellent acid and alkali resistance, oil resistance, applicable temperature -40℃~100℃, anti-ultraviolet aging, suitable for outdoor humid environment.
4. Screening efficiency and clogging
Rubber Screen Panel: The inverted cone screen hole has strong self-cleaning ability, but the elastic deformation affects the precision of fine particles.
Polyurethane screen plate: The screen hole shape is regular (square/circular), the hardness is high and the deformation is small, and the "secondary bounce" structure is used to reduce the clogging of wet and sticky materials.
5. Noise and energy consumption
Rubber Screen Panel: strong vibration absorption, low noise of 5-20 decibels, and low energy consumption.
Polyurethane screen plate: noise is reduced by 10-15 decibels, long-term wear resistance and stable energy consumption.
3. Application scenarios and industry adaptation
|
Screen plate type |
Applicable materials |
Suitable equipment |
Typical industries: |
|
Rubber Screen Panel |
Medium hardness, dry/slightly wet materials (raw coal, quartz sand) |
Small and medium-sized vibrating screens, circular vibrating screens |
coal preparation plant, sand and gravel building materials plant, |
|
Polyurethane screen plate |
High hardness, corrosive, wet and sticky materials (gold mines, construction waste) |
Large vibrating screens, tension screens |
Metal mine, solid waste treatment, water conservancy project |
4. Cost and maintenance comparison
Purchase cost: The price of polyurethane screen plate is 30%-50% higher, but it has a long life and lower overall cost.
Maintenance difficulty:
Rubber Screen Panel: The bonding layer needs to be checked regularly and the replacement frequency is high.
Polyurethane screen plate: Modular design supports local replacement and convenient maintenance.
5. Selection suggestions
Choose Rubber Screen Panel: limited budget, low material hardness, high equipment vibration frequency (such as high-frequency screen).
Choose polyurethane screen plate: highly corrosive environment, wet sticky material clogging problem, and pursuit of long-term screening accuracy (such as ore selection).
6. Actual case reference
Coal mine raw coal screening: Choose Rubber Screen Panel, which has low cost and strong self-cleaning ability and is suitable for dry environment.
Gold mine wet ore processing: Use polyurethane screen plate, which is wear-resistant and corrosion-resistant, and significantly reduces mud and water clogging.
