SCM production line

The supplementary cementitious materials (SCM) production line serves as a green nexus linking solid waste, technology, and construction. It transforms industrial by-products such as fly ash and slag into high-reactivity materials with controlled performance through intelligent grinding and precise homogenization. These materials ultimately become critical components in major projects like super high-rises and cross-sea bridges, playing a central role in enhancing durability and reducing carbon emissions.

The main purpose:

1. In cement production, it is directly mixed into cement in a certain proportion. It is a component material in the production of slag Portland cement to improve the performance of cement and reduce production costs and energy consumption. The addition of water slag in slag Portland cement The amount is 20%-70% by weight.

2. In ready-mixed concrete and cement products, it can replace a moderate amount or excessive amount of part of the cement. It can be used as a cementing material to directly mix concrete and mortar to improve its working performance. Slag powder appears in the construction market as a vertical product and is widely used in concrete. , can replace about 50% of cement.

Volcanic Ash

Volcanic ash is an indispensable key material for achieving high performance, and low-carbon objectives in modern sustainable civil engineering and the cement industry.

Modern technology grinding system

LM vertical mill is a special equipment for scm powdering. It integrates crushing, drying, grinding and grading transportation. The system is simple and the layout is compact. It covers an area of about 50% of the ball mill system and can be arranged in the open air. Therefore It can greatly reduce investment costs; and the grinding roller directly grinds the materials on the grinding disc, which has low energy consumption and saves 30% to 40% of energy compared with the ball mill system.

SCM powder preparation

Unique hydraulic device

The grinding roller can be turned out of the machine with a hydraulic device, making maintenance very convenient. The grinding roller cover can be turned over to extend its service life. The mill can be started without load, eliminating the trouble of difficult startup. Equipped with grinding roller limit device to avoid severe vibration of the mill.
Unique grinding roller sleeve

The proprietary grinding roller sleeve can be turned over for use, extending the service life of the wear-resistant material.
Eliminate booting difficulties

There is no need to put material on the grinding plate before starting up, and the mill can be started without load, eliminating the trouble of difficult startup.
Unique limiting device

It is equipped with a grinding roller limit device to avoid severe vibration caused by material interruption during the working hours of the mill.

Stable output

Due to the function of the hydraulic device and the limiting device, the gap between the grinding roller and the grinding disc can be adjusted to a constant gap with wear, thereby increasing the grinding pressure and stabilizing the output.
Grinding roller sealing device

Equipped with a new grinding roller sealing device, the sealing is more reliable and no sealing fan is required.
Thin oil lubrication for grinding roller shaft

The grinding roller shaft is lubricated with proprietary thin oil and adopts cyclic forced lubrication, which is stable and reliable and has a long service life.
Powder separator frequency conversion control

The powder separator adopts frequency conversion control, and the fineness adjustment is convenient and fast, and the particle size is stable.

SCM Powder Making Process Flow

The core process—“Grinding–Separating–Collecting–Homogenizing”—forms a closed-circuit loop, enabling continuous, efficient, and high-quality production.
Raw materials (e.g., fly ash, slag) are batched and proportioned, then elevated to a vertical roller mill for efficient grinding and simultaneous drying. The ground material is carried by air flow to a dynamic separator, where qualified fine powder is selected, while coarse particles are returned to the mill for regrinding. The qualified fines are collected by a dust collector, stored and homogenized in a blending silo, and finally dispatched via packaging or bulk loading systems.
