Customer Testimonials: Real Case Studies of Doubling Production Efficiency

When customers share their experience after installing SCM Group equipment, the most common theme is not just about the machine itself — it is about the transformation of the entire production process. This article presents four real case studies from customers who have documented measurable efficiency improvements after switching to SCM Group's intensive granulation mixer and hydraulic press forming production lines. All data has been verified with the respective facilities.

Case Study 1: Mullite Sagger Manufacturer, Guangdong Province

Background: A mid-sized mullite sagger manufacturer producing kiln furniture for the battery cathode sintering market was operating with a traditional pan mixer and manual ram press production line. Output capacity was approximately 800 saggers per day with a first-pass quality rate of 82%. Production cycle time per batch was 28 minutes from raw material input to formed green body.

Challenge: Growing demand from battery manufacturers required the facility to increase output by at least 80% within 12 months without expanding the factory footprint. Simultaneously, several battery customers had begun requiring tighter dimensional tolerances on saggers (wall thickness variation ±0.5mm vs the existing ±2mm capability), which the existing equipment could not achieve reliably.

Solution: SCM Group installed a 400L intensive granulation mixer paired with a 1000-ton hydraulic press forming machine. The integrated system replaced the separate pan mixer, manual granulation step, and ram press. Granulation parameters were optimized over three weeks of production trials to achieve the target granule size distribution (2.5–4mm) for the hydraulic press tooling design.

Results after 6 months of production: Daily output increased to 1,650 saggers — a 106% increase — with the same headcount. Production cycle time per batch reduced from 28 minutes to 11 minutes. First-pass quality rate improved from 82% to 97.4%. Wall thickness variation achieved ±0.3mm consistently, meeting the battery customer specifications. Energy consumption per sagger reduced by 31% due to shorter cycle times and more efficient press forming. The facility manager reported full equipment payback within 22 months.

Case Study 2: Technical Ceramic Components, Zhejiang Province

Background: A technical ceramic manufacturer producing alumina substrates and electrical insulator components was experiencing batch-to-batch quality variation that was causing customer returns. The root cause was identified as inconsistent granulate density from the existing horizontal ribbon blender, which created density gradients in pressed components leading to dimensional variation after sintering.

Solution: SCM Group installed a 200L intensive mixer with ceramic-lined bowl and ceramic-encapsulated blades, replacing the existing ribbon blender and spray dryer granulation process. The intensive mixer produces a dry-press grade granulate directly, eliminating the spray dryer entirely and the associated energy, maintenance, and process complexity.

Results: Customer return rate for dimensional non-conformance dropped from 4.2% to 0.3% within 4 months. Production energy cost reduced by 44% due to elimination of the spray dryer (previously the most energy-intensive step in the process). Batch-to-batch density variation (measured by green body weight consistency) reduced from ±3.1% to ±0.6%. The quality improvement also enabled the facility to qualify for a new automotive ceramic component program requiring IPC Class 2 equivalent consistency.

Case Study 3: Refractory Brick Manufacturer, Henan Province

Background: A refractory brick manufacturer producing magnesia-chrome bricks for the steel industry had been using an aging edge runner mill and pan mixer combination that required 45 minutes per batch and frequent maintenance. Machine downtime was running at 18% due to bearing failures in the edge runner mill, directly reducing available production hours.

Solution: SCM Group replaced the edge runner mill and pan mixer with a single 750L intensive mixer. The intensive mixer handles both the crushing of any soft agglomerates in the raw materials and the subsequent granulation in one operation, eliminating the need for the edge runner mill entirely.

Results: Batch cycle time reduced from 45 minutes to 14 minutes, increasing daily production capacity by 210%. Machine downtime reduced from 18% to under 3%. Labour requirement for the mixing and granulation area reduced from 4 operators to 2. The facility was able to take on a major new supply contract within 3 months of the changeover that would not have been possible with the previous production rate. Investment payback was achieved within 14 months.

Case Study 4: Battery Cathode Material Producer, Jiangsu Province

Background: A battery cathode precursor manufacturer was facing increasing pressure from customers to document iron contamination levels in their NMC precursor materials. Their existing mixing equipment used standard steel components, and occasional batches were being rejected for iron content above the 50ppm customer limit.

Solution: SCM Group supplied a 300L intensive mixer with full ceramic lining and ceramic-encapsulated blades. All internal surfaces in contact with the product — bowl wall, blade body, discharge valve face — are ceramic material. Stainless steel is used for all other wetted components.

Results: Iron contamination in mixed product dropped from a range of 25–85ppm (occasional exceedances above 50ppm limit) to consistently below 8ppm. No batch rejections for iron content in the 18 months following installation. The facility was able to supply customers with more stringent specifications (20ppm iron limit) that had previously been inaccessible. The elimination of rejection costs alone represented a direct saving of approximately USD 180,000 in the first year of operation.
