The roller sieve, also known as a mud and stone separator or a butterfly sieve, typically consists of a blade disk and shaft assembly. It disintegrates and sorts materials to be classified through the shaft's rotation. By synchronously circulating and transporting materials with force and the blade disk, it continuously processes wet, clay, and other difficult-to-separate and clean materials, including light substances and stones. The working principle involves a motor-driven interlocked shaft that rotates with irregularly shaped devices. The sieve surface is composed of many linearly arranged rotating bearings, with identical sieve disks aligned on the roller. The rollers are driven by gears to rotate the chain. The rotation direction is consistent with the flow direction of the raw materials, and there is a gap between the shafts. Irregular, wear-resistant devices mounted on the shaft support the movement of large-grained materials forward. Since the sieve shaft is customized for different running directions, when materials running at different speeds meet on the sieve surface, they begin to run axially, evenly distributing the materials across the sieve surface, enhancing the sieve's efficiency. Fine-grained materials fall into the separator's bottom and are transported out by a conveyor belt.

Additionally, pay attention to the following aspects for better cleaning and clogging prevention of the sand and stone separator: The drainage channel is a safe passage for the separator slurry to enter the sedimentation pond, and it must be cleared at all times to prevent sedimentation砂浆 from causing blockages. The sedimentation pond is a storage pool for the separator's cleaning砂浆 and sedimentation. When the water level above the secondary sedimentation pond reaches 1 meter, ensure there is adequate indoor sedimentation space and clear it immediately. The water depth in the wastewater well (i.e., sedimentation pond) must be maintained at over 1.5 meters, and clear it immediately if it's insufficient. The sand and stone separator itself has the advantage of simple and convenient operation. It requires minimal attention during operation, saving a significant amount of human resources and offering high returns. However, pay special attention to the cleaning stage of the sand and stone separator, and assign specific personnel for maintenance and cleaning.
