Description

Technical Field

[0001] This utility model relates to the technical field of perlite processing equipment, and in particular to a perlite filter aid pulverizing equipment. Background Technology

[0002] Perlite filter aid is made from natural perlite ore sand that has been calcined and expanded at high temperatures before being crushed. After crushing, the surface of the perlite particles becomes uneven, forming a serrated structure. These particles are squeezed and interlocked during the filter cake formation process, creating a rough filtration network with many interconnected channels. This network not only blocks micron-sized particles but also boasts a high porosity of 80%-90%, ensuring that the liquid can pass through quickly while effectively intercepting impurities, achieving highly efficient filtration.

[0003] Traditional crushing equipment, such as the perlite filter aid crushing device disclosed in Chinese utility model patent CN219559836U, uses a drive mechanism to rotate a main shaft. The rotation of the main shaft causes a grinding roller connected to a connecting rod to approach a grinding disc under centrifugal force. The grinding roller rotates around the main shaft and cooperates with the grinding disc to crush the perlite raw material. An adjustment mechanism allows for limiting the distance between the connecting rod and the grinding disc during operation, thus preventing over-grinding of the perlite. However, due to the varying particle sizes of the perlite raw material, smaller particles are prone to over-grinding during the crushing process, which also reduces crushing efficiency.
