The crushing screen machine consists of multiple parts: driving part: usually using a waterway amphibious motor, double motor type or three motor type can be selected according to the width of the canal and the processing capacity, crushing part: the two shafts drive the blades to cross and crush, the blade is the most important part, the blade needs to have high hardness and high process requirements, usually only imported blades are more reliable, the screen part: this part is used to block large particles of garbage. In order to avoid excessive head loss, it is recommended to choose a gap of about 20mm. The screen part is also called a drum, which has a rotating rake that pushes the garbage to the crushing part. Generally, they are divided into single-drum and double-drum, which are selected according to the flow rate and channel width. The cutting blades used in existing crushing-type screen machines are generally integral structures with a certain thickness. After long-term use, the blades are prone to damage. When replacement is required, the entire drive shaft is often required to be disassembled and the damaged blades are replaced. It is inconvenient to replace a damaged single cutter head.
