Closed-Circuit Mobile Crusher is a portable machine designed for crushing stones, primarily used in construction and mining industries. The machine is designed to break down large stone blocks into smaller, manageable pieces, typically to be used in asphalt, concrete, or road construction. The term "closed-circuit" refers to the fact that the crushed material circulates within a processing line, allowing for more accurate control over the size of the crushed stones.

Purpose and Applications:

Closed-circuit mobile crushers are designed to minimize dust and particulate matter during the crushing process. They can process various types of stones, including granite, basalt, limestone, etc. These crushers are mainly used in asphalt production, concrete plants, road construction, quarries, and various construction projects.

Working Principle:

Closed-circuit mobile crushers operate by feeding the raw material through a feeder, which directs it to a crusher. The crusher breaks the stones into smaller sizes, which are then separated by a screen. Stones that do not meet the desired size are sent back into the crusher, forming a closed-loop system. This cycle continues until the desired particle size is achieved. This closed-circuit process allows for continuous recycling of material.

The primary advantages of closed-circuit mobile crushers are their high efficiency and portability. These machines can be relocated on-site, providing flexibility for various projects.
