IPA roll compactors and mills are durable machines built for long lasting run time. However, all machines require maintenance and often replacing of parts to continue producing optimum product quality and throughputs. Production rates can unknowingly decline over time from a process issue or deteriorating parts.Whether you are running a compactor 24/7 or producing batches of material, it is important to keep your equipment at peak performance. Below you will find guidelines of commonly occurring problems and suggested resolutions.
These process conditions also apply for competitor machines, such as the Fitzpatrick Chilsonator & Fitzmill. Should you have a maintenance question that is not list below or require PLC software/hardware upgrades, please reach out to IPA and we can problem solve with you.
