Founded in 1964
OEM wear parts on an Air Classifying Mill (ACM) were failing so fast that our partner had to shut down and replace components daily, if not hourly.
Since this specialized grinding equipment is crucial to proper particle size reduction and classification, the chronic wear failures were crippling the dry chemical manufacturer’s productivity and affecting profitability.
Good Earth Tools proposed adding solid tungsten carbide to the wear surfaces of each vulnerable component in the Air Classifier Mill, with the goal of substantially extending both wear life and uptime.
After evaluating the application, our team engineered, built, tested, and implemented custom StarCarb-protected solutions.
OEM parts show heavy wear after 24,000 LBS
StarCarb-protected parts show no wear after 569,000 LBS.
Even after processing more than 569,000 lbs of product — a 24x improvement from the previous 24,000 lbs — the StarCarb-protected wear parts from Good Earth Tools continued to perform at their peak.
By maximizing uptime and minimizing replacement parts and labor, our tungsten carbide solutions helped bring maintenance costs down from $2m to $70K, a near 97% cost savings.
