What is the reason for the screen blockage in the stabilized soil mixing station?

Stabilized soil mixing station is a mechanical equipment used to produce stable soil in highways and bridges. It is mainly composed of cement tanks, metering and conveying equipment, mixing equipment, etc. During the use of equipment, some customers report that they will encounter screen blockage. The problem affects the production schedule. What is the cause of the screen blockage?

The screen mesh of the stabilized soil mixing station is too small. If a small amount of stone debris remains on the vibrating screen, it will not pass through the sieve hole and gradually block the sieve hole. If it is a stone particle containing a large amount of critical near the size of the sieve, it contains more needle-shaped stone. The diameter of the wire of the woven mesh is relatively thick, and the good steel wire is both wear-resistant and tough, and can effectively improve the mesh passage rate.

 

Stabilized soil mixing station's requirements for soil: The general requirements for soil are easy to break, meet certain grading, and facilitate rolling forming. The soil used for the cement stabilized layer in expressway engineering is generally divided into the following three types according to the particle size and composition of the constituent particles in the soil (including gravel, gravel, sand particles, excluding clods and soil mass). Fine-grained soil: the particle size of the particles is less than 9.5mm, and the content of particles less than 2.36mm is not less than 90% (such as various clay, silty soil, sandy soil, sand and stone chips with different plasticity indexes) . Medium-grained soil: the particle size of the particles is less than 26.5 mm, and the particle content of less than 19.0 mm is not less than 90% (such as gravel, gravel, graded gravel, graded gravel, etc.). Coarse-grained soil, the particle size of the particles is less than 37.5 mm, and wherein the particle content of less than 31.5 mm is not less than 90% (such as gravel, crushed stone, graded gravel, graded gravel, etc.).

 

Good equipment is the basic guarantee for smooth construction. The screen of the stabilized soil mixing station produced by Jianxin Machinery is made of high quality and durable steel wire. In the actual use process, the screen blockage rarely occurs. For details, please contact Jianxin Machinery Sales Hotline.
