The specifications of the rotary tooth rake cleaning machine and the circulating tooth rake grid cleaning machine are divided according to the machine width, covering GSLY300-3600 models, and the corresponding models adopt parallel design. The core configuration and selection of $r $n are based on the multi specification selection of $r $n rake teeth gap, including 1mm, 3mm, 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, etc. The selection of $r $n should take into account factors such as water flow rate, lifting height, total solid-liquid separation capacity, as well as the shape and particle size of the separated material, and can also be matched with different materials. $r $n size adaptation and customization services $r $n devices can be flexibly extended according to user needs and actual usage scenarios.
