Description

Screening equipment for cast steel pill production

Technical Field

The utility model relates to the technical field of screening equipment, in particular to screening equipment for cast steel pill production.

Background

The utility model mainly relates to the screening equipment technology, and cast steel pellets are materials commonly used in the fields of projectile cleaning, surface treatment, steel processing and the like. It is typically made of high carbon steel or alloy steel, with high hardness, wear resistance and impact resistance. The screening of the cast steel shot refers to the process of classifying the cast steel shot in particle size. The cast steel shot is an abrasive material used for the processes of casting cleaning, sand blasting and the like, and the particle size distribution directly influences the cleaning effect and the service life of the cast steel shot. Generally, cast steel pellets are screened by placing a sample of cast steel pellets into screening equipment and separating out cast steel pellets of different sizes by the pore size of the screen. Typical screening equipment is a vibrating screen, a cyclone screen, or the like. During screening, cast steel pill samples are uniformly placed into a feed inlet of screening equipment, and then the equipment is started to vibrate or rotate. Under the action of vibration or rotation, the cast steel pill sample can gradually pass through the aperture of the screen, larger particles can be blocked on the screen, and smaller particles fall into a collecting box below through the screen. After sieving, cast steel pellets with different granularities can be respectively collected and used according to the needs. Generally, the size classification of cast steel shot is generally carried out according to international standard ISO11124-3, and is classified into different particle size classes such as G10, G12, G14, etc. Screening of cast steel shot is very important to ensure its cleaning effect and service life, because the impact force and cleaning capacity of cast steel shot of different particle sizes in the cleaning operation are different. Therefore, when cleaning or sand blasting using cast steel shots, it is necessary to select cast steel shots of an appropriate grain size level according to specific process requirements and characteristics of the cleaning object.
