What are the differences between relaxation screen and vibrating screen?

The relaxation screen and Pantalla vibrante are both used in various industries to process materials, but they operate based on different principles and serve different functions.

Difference between relaxation screen and vibrating screen

1. Operation Principle:

Relaxation Screen:

A relaxation screen typically refers to a type of screen where the material being processed is allowed to settle or “relax” as it moves across the screen surface. This allows the particles to find natural gaps and fall through the mesh more easily.

It usually relies on gravity and controlled movement of the material, allowing fine particles to pass through openings without significant agitation.

This method is more suitable for delicate or fragile materials that might be damaged by vigorous motion.

Vibrating Screen:

A vibrating screen works by using a motor to create vibrations that agitate the material being screened. The entire screen surface vibrates, causing the material to move in a specific direction.

The constant vibration helps in separating particles of different sizes more efficiently. Vibrating screens are usually more aggressive and are designed to process large volumes of material in shorter periods.

They come in various types, such as circular, lineal, o movimiento elíptico, depending on the vibrating mechanism used.

2. Intensity of Motion:

Relaxation Screen:

Has gentle movement, which allows materials to settle and find natural spaces through which they can pass. There is little to no agitation, relying more on the material’s flow across the screen.

Suitable for fine or delicate materials that need less forceful handling.

Vibrating Screen:

The screen surface experiences vigorous, repeated vibrations, which force the material to move across the screen in a controlled manner. The motion helps separate fine and coarse materials quickly.

Ideal for heavy-duty applications, such as mining, construcción, and bulk material processing.

3. Application and Materials Processed:

Relaxation Screen:

Often used for fine screening and materials that are sensitive to damage or breakage. Examples include processing fragile particles, polvos, or granular substances.

Can be used in food processing, chemical industries, or any application where gentle handling is essential.

What are the reasons for the explosion of glass tempering furnace?

Explosions in glass tempering furnaces can occur due to a variety of reasons, many of which stem from operational issues, material defects, or improper maintenance. Understanding these causes can help prevent such incidents.

Causes of explosion of glass tempering furnace

glass tempering furnaces

1. Glass Defects

Nickel Sulfide Inclusions (NiS): Nickel sulfide inclusions are microscopic impurities in glass that can cause it to shatter spontaneously. These inclusions can expand during the tempering process and lead to delayed failure, sometimes causing the glass to explode after being tempered.

Internal Stresses: If the glass is not properly annealed before entering the tempering process, internal stresses can build up. These stresses can cause the glass to explode under heat or when exposed to rapid cooling.

Surface Defects: Scratches, papas fritas, or cracks on the glass surface can act as stress concentrators during the tempering process, leading to failure and explosion.

2. Incorrect Furnace Settings

Uneven Heating: If the furnace does not heat the glass evenly, it can cause thermal stress. Uneven heating or cooling (temple) of the glass can lead to differences in expansion and contraction, resulting in glass breakage.

Overheating: Glass that is overheated in the furnace may develop severe internal stresses. When exposed to quenching (rapid cooling), it may fail and shatter explosively.

Incorrect Temperature Gradient: A proper temperature gradient between the heating and cooling sections of the furnace is crucial. If the temperature changes too rapidly or is unevenly distributed, it can cause thermal shock to the glass.

3. Improper Quenching (Enfriamiento) Proceso de

Insufficient or Excessive Cooling: The quenching process, where the glass is cooled rapidly, must be well-regulated. If the cooling is too rapid or uneven, it can lead to a high stress differential between the inner and outer layers of the glass, causing it to shatter.

Improper Airflow: The airflow during quenching should be evenly distributed. Uneven airflow can lead to localized cooling, creating stress points that may cause the glass to break or explode.
