Coperion: Cement Blending with Manufacturing Pull Principle

Cement Blending On Demand: Coperion's Pull-Based Production in Action

Blended cement is usually produced ahead of demand and parked in silos. Coperion's system takes the opposite route: it blends exactly what has been ordered, when it is ordered.

The approach is built around the Manufacturing Pull Principle, which flips the traditional logic of cement production. Instead of producing in advance and hoping demand will follow, the plant blends to order. That means less inventory, more flexibility, and fresher product.

The Problem with Traditional Cement Blending

Most cement producers still rely on a push system: large batches are blended in advance based on forecasted demand, then stored in silos, taking up valuable space and tying up capital. If the forecast is off — which it often is — producers are left with excess inventory or outdated product.

The push system isn't flexible either. If a customer changes a spec, or a new recipe is needed, the plant has to wait until the right material is blended and available. That slows everything down.

Coperion's Alternative: Blend Only What's Needed

The Coperion system supports a pull-based approach: it produces only what has been ordered, just in time. No waiting for inventory, and no storing blended material "just in case."

The core of the system combines weighing and blending in one step. Instead of running material through a traditional mixer, Coperion uses:

• A rotating measuring wheel that meters material flow
• A Coriolis flowmeter that measures mass flow in real time
• A control system that adjusts blending ratios continuously

The result: precise, consistent cement blends delivered directly into the packaging or transport line, without any intermediate storage.

How It Works in Practice

The video shows the system blending main materials and additives in real time. As the components flow through, their mass is measured precisely and the ratios are adjusted continuously, so recipe accuracy is maintained without interrupting the flow of material.

There's no stop-start batching, no stored mixed product, and no delay between order and production. Cement is blended fresh and moves immediately to the next stage — a truck, a silo, or a bagging line.

Where the Setup Fits Best

The pull-based arrangement pays off where:

• Storage space is limited
• Multiple product types are handled daily
• Clean, fast recipe changeovers are needed
• Production must respond directly to sales orders
• Cost and resource efficiency are priorities

It also suits retrofit projects where a traditional blending system with large silos isn't practical, and it reduces product waste along the way.
