100 kg Ball Mill Project Overview

The client is an established chocolate manufacturer in Ethiopia. The company already runs a large production plant, and at the time of this inquiry it was building a satellite factory inside Addis Ababa to serve city demand without hauling product from the main site. The satellite plant came with two hard constraints: a much smaller floor area, and a product mix wider than plain chocolate.

An 12 September 2026 bei 05:14, the buyer, Solomon, sent his first message through WhatsApp:

“Interested in 100kg capacity ball mill for chocolate. Aber, I also want to produce other pastes and creams with it. I need a ball mill easy to clean, pflegen, add or remove products from the ball mill.”

From the first exchange, Solomon made it clear that he was not a first-time equipment buyer. He had been running large-capacity mills, he had bought grinding equipment in China before, and he knew exactly which failure mode he wanted to avoid: viscous product blocking the circulation line and forcing a full teardown of pipes and the tank bottom.

The commercial outcome was a single-machine order built around a 100 L Kugelmühle für Schokolade, specified with an upgraded 1.5 kW rotary lobe pump and a pump body customised for high-viscosity material, quoted at USD 1*,643 EXW with a 120-day validity.

Client Requirements for the Chocolate Ball Mill

Solomon’s brief was unusually complete for a first message. Across the first week of discussion he defined seven requirements, several of them shaped by equipment he already owned.

Kompakt 100 kg capacity with large-machine performance. The satellite plant needed a small mill, but he did not want a downgraded machine. He asked for “a 100kg compact ball-mill with similar spec to the larger ones.”

Multi-product processing capability.
While chocolate is the core product, it is not the only one. He wants the same tank equipment to process other pastes and creams, specifically citing jams, Erdnussbutter, and cookie butter (similar to Nutella or Biscoff spreads) as future production targets.

Pure cocoa butter chocolate vs. cocoa butter substitute (CBS) Schokolade.
Gondor asked whether he uses cocoa butter or cocoa butter substitutes for grinding. He replied, “I produce both pure cocoa butter chocolate and CBS chocolate,” and immediately inquired about the equipment’s compatibility with CBS.

No circulation clogging issues.
His primary technical concern was: “I know pumps can transport and circulate high-viscosity chocolate, but will this cause clogging? With my current ball mill, I sometimes have to dismantle the bottom section and piping to clear blockages, which leads to downtime.”

Rapid cleaning and ingredient loading.
He specifically asked if there were “openings large enough to add ingredients and clean the interior of the ball mill.” Switching products—for instance, between chocolate and cookie butter—must be a practical, feasible process to meet daily production needs.

Ability to handle extremely thick materials containing particulates.
The cookie butter he plans to produce consists of approximately 50% cookie powder, with the remainder being soft fats; he also intends to add cookie pieces for a crunchy texture. He described the consistency of this mixture as “much thicker” than the salad dressing shown in Gondor’s reference video.

Clear quotation and electrical compatibility.
Alongside technical discussions, he requested a “quotation that includes all necessary spare parts” and confirmed that his factory’s power supply standard is 220 V / 50 Hz.

Conflict between footprint constraints and material viscosity.

A compact equipment design typically implies a smaller pump body and narrower transfer piping. Jedoch, the product list Solomon intended to process presented the opposite scenario: the most viscous materials on the list were the very new products that drove his decision to purchase the equipment in the first place.

Concerns stemming from past equipment failures.

This objection was not raised without cause. He had previously experienced production stoppages in his existing grinding equipment due to pipe blockages and described the subsequent disassembly and cleaning process in detail. Any response that disregarded this experience would have been dismissed as mere sales rhetoric.

Justifying the price of equipment modifications.

The upgraded pump increased the equipment’s cost. Solomon immediately noticed this and asked, “Is the price hike due to the motor?” Folglich, a detailed, item-by-item breakdown of the configuration was required to justify the price.

Skepticism regarding Chinese suppliers.

Although Gondor explained the manufacturing quality, Solomon was blunt in his response: “The Chinese companies I’ve worked with before said the same thing, Aber…” In diesem Stadium, the primary obstacle to the partnership was credibility, not technical specifications.

Switching between product varieties in a confined space.

Due to limited space at the branch facility, the grinder had to be cleaned and reloaded in situ; this made the size of the hopper opening and the discharge path critical factors affecting the operational workflow.

Voltage verification.

It was confirmed that the branch facility’s industrial power supply was 220 V / 50 Hz (einphasig). This necessitated a single-phase configuration, ruling out the 380 V three-phase power supply used in Gondor’s larger 500-liter and 1000-liter models.

Unsere technischen Empfehlungen

Gondor recommends a single 100-liter capacity unit rather than a scaled-down version of a standard model; the pumping and temperature control systems are designed based on the highest-viscosity product in the Solomon list (going beyond the requirements for chocolate alone).

1. Kernausrüstung: 100-Liter SUS304 Grinder with PLC Control

The tank is constructed entirely from food-grade 304 Edelstahl, featuring full PLC control, automatic variable-frequency speed regulation, and an insulated water jacket for temperature management. Designed to achieve a grinding fineness of 18–25 μm, the unit handles both pure chocolate and cocoa-equivalent/compound chocolate, eliminating the need for secondary refining for the specified products.

2. Pumping System: 1.5 kW Lobe Pump with Custom Pump Body

This represents a critical engineering upgrade. Standard equipment typically employs a lobe pump with a 0.75 kW-Motor; while sufficient for chocolate mass, such motors lack the power to handle pastes containing 50% biscuit powder. Gondor engineers selected a 1.5 kW lobe pump paired with a custom pump body designed for high-viscosity materials. Zusätzlich, the transfer piping has been widened to ensure the sampling channel remains unobstructed during high-load operation.

3. Cleaning and Product Changeover Access

The tank features a 900 mm diameter opening, providing ample space for manual access for cleaning or direct ingredient loading. Combined with the wide-bore piping design, the unit allows for daily product changeovers—switching between chocolate, Nusspasten, and biscuit creams—without requiring the disassembly of bottom components.

4. Temperature and Viscosity Management

The equipment is equipped with heating and constant-temperature control capabilities. Gondor used this characteristic to explain to Solomon the potential changes in material state on the production floor: the viscosity of the chocolate paste decreases as the temperature rises and causes it to re-solidify as the temperature drops; folglich, the apparent viscosity within the tank depends not only on the formulation but also on the temperature setting. This exchange transformed what was initially a complaint about “excessive viscosity” into an operational parameter that the factory could control independently.

Why this solution meets the customer’s needs

Pump selection was based on the most challenging product, not the easiest.

While a 0.75 kW lobe pump could handle chocolate mass, it could not reliably process a 50% biscuit crumb paste containing particulates. Auswählen eines 1.5 kW lobe pump with a custom-designed pump housing eliminated the risk of equipment failure and associated downtime.

Capacity requirements were met without compromising equipment specifications.

The customer required a compact machine that delivered the performance of large-scale equipment. This 100-liter unit features the same SUS304 construction, PLC control system, and 18–25 μm grinding fineness found in larger units, enabling the satellite plant to perform independent fine grinding without having to settle for laboratory-grade equipment.

Multi-product processing was incorporated as a key design requirement.

The equipment features a 900 mm wide feed inlet, spacious piping, and sampling ports, allowing chocolate, Nusspasten, and biscuit creams to be processed on a single machine within a compact footprint—exactly what the customer originally requested.

Price justification through specific configuration details.

When the customer questioned whether the motor was driving up the price, we highlighted key specifications: an upgraded pump housing, custom housing design, SUS304 construction, a premium-brand motor, a 12-month warranty, and technical support services. Buyers could verify each of these items during the price comparison process.

Risk shifted to the manufacturing plant rather than the buyer’s site.

Test runs using the customer’s specific recipes were conducted prior to shipment to ensure proper operation; this process moved verification to an earlier stage, ensuring any issues were resolved at the factory without incurring additional costs for the customer.
