During the collection and transportation process, various foreign matters are mixed into the sludge, which leads to the failure of the sludge dryer to work continuously and stably, and even the foreign matters are often stuck in the slitting machine, causing damage to the slitting machine. Our company specially develops a slitting machine with a foreign matter preventing function, which effectively solves the problem of continuously and stably slitting the sludge mixed with foreign matters without damaging the slitting machine.

[0003] At present, the existing slitting machines cannot handle the sludge mixed with foreign matters, especially the sludge mixed with bolts, iron blocks and hard stone blocks, which will cause the slitting machine to be stuck and damaged, and the slitting machine rolling cutter will be damaged, resulting in long-term shutdown for maintenance and affecting production. The maintenance cost is particularly high and the maintenance time is particularly long, which is the old and difficult problem of the sludge dryer on the market. SUMMARY
