1. Project Background: Arabic Gum Powder for Food and Pharma Use

Our UK customer is a processor and packer of arabic gum powder used in food, beverage and pharma-related applications. They purchase arabic gum in granular or irregular chunks and need to pulverize, classify and mix it into a stable, fine powder ready for filling and downstream blending.

The existing process relied on smaller standalone mills and manual mixing, which led to inconsistent fineness, unstable capacity and frequent manual intervention. To support long-term contracts with brand owners, the customer wanted a dedicated milling + screening + mixing line with stable throughput and long service life.

2. Customer Pain Points: Consistency and Long-Term Reliability

During the technical discussions, the customer highlighted several key pain points:

• Unstable capacity
  Output varied significantly depending on operator and raw material condition. This made it hard to plan production and meet tight delivery schedules.

• Inconsistent product fineness
  Without proper classification, some batches were too coarse and others overly fine, affecting dissolution behavior and performance in formulations.

• Unstable motor load
  Manual or gravity feeding caused fluctuations in load and current. This increased mechanical stress and raised concerns about long-term reliability.

• Need for a long-service solution
  The customer wanted a line that could run for decades with planned wear-part replacement, not a “throwaway” machine that would require full replacement after a few years.

3. Solution: 120kg/h Arabic Gum Milling & Mixing Line

In response, we supplied a 120kg/h arabic gum powder milling and mixing line tailored to the UK customer’s requirements. The key configuration features are:

• Designed capacity: 120 kg/h
  The line is engineered to deliver a stable 120 kg/h of finished arabic gum powder under normal operating conditions, covering current order volume with room for moderate growth.

• Crushing + screening for controlled fineness
  Arabic gum is first mechanically pulverized, then passed through a screening section. By selecting the proper screen mesh, the customer can precisely control the final powder fineness to match different application needs.

• Screw feeding for uniform material input
  A screw feeding system delivers raw material into the mill at a controlled rate. This ensures uniform feeding, which directly stabilizes the grinding process, reduces blockages and helps maintain consistent product quality.

• Stable current and stable capacity
  Because the feed is even, the mill runs under stable current and load. This reduces mechanical and electrical stress on the motor, smooths out capacity and improves overall process reliability.

• Integrated mixing capability
  After milling and classification, the powder is discharged into a mixing section (or integrated mixer, depending on layout). This ensures homogeneous product, ready for packing or for further use in customer-specific blends.

4. Lifetime and Maintenance: 20-Year Equipment Life, Planned Wear Parts

The line is designed not only for performance today, but also for long-term operation:

• Equipment lifetime up to 20 years
  With proper routine maintenance and normal operating conditions, the core equipment is designed to remain in service for around 20 years. Structural parts, frames, housings and main mechanical components are dimensioned for long-term duty.

• Cutters as wear parts (6–12 months)
  The cutters (blades/beaters) in the milling chamber are treated as normal wear parts. Depending on material hardness, running hours and cleaning practices, typical service life is 6–12 months before sharpening or replacement is needed. This is clearly communicated as part of the maintenance plan so the customer can stock spare cutters and avoid unplanned downtime.

• Stable load = reduced stress
  Thanks to the screw feeder and stable current, the motor and mechanical components are less exposed to overloads and shock loads, which helps extend service life and keep total cost of ownership under control.

5. Results: Controlled Fineness, Stable Output, Predictable Maintenance

After commissioning and ramp-up, the UK customer reported several concrete improvements:

1. Consistent 120 kg/h output
   The line runs at its design capacity with minimal operator intervention, making production planning more accurate and reducing overtime needs.

2. Precisely controlled product fineness
   By selecting screen mesh sizes, the customer can ensure that each batch of arabic gum powder meets the required fineness specifications for different end uses.

3. Stable current and smoother operation
   The screw feeding system keeps motor current within a narrow band. This has improved reliability, reduced nuisance stops and made the process more predictable for operators.

4. Clear maintenance strategy
   With a 20-year design lifetime for the main equipment and a defined 6–12 month life for cutter wear parts, the customer can plan maintenance and spare-part inventory instead of reacting to unexpected failures.
