What does Fine Mill mean?
Fine mill describes the process of fine grinding. The fine grinding systems used enable agglomerates to be broken up and solid grain structures to be broken down to the finest grinding. The material to be ground is rubbed in a finely adjusted grinder in order to achieve the most homogeneous grinding possible. Fine grinding usually takes place at low speeds in order to increase the storage stability of the products. This type of grinding makes it possible to achieve very narrow grain spectra.
The storage stability of certain products can also be improved with the addition of liquids by means of fine grinding. Fine grinding processes are particularly suitable for breaking down agglomerates – especially for crystallized goods.
Fine Mill at Ebbecke Process Engineering
All grinding systems for bulk material processing are made of stainless steel and designed as closed systems with dosing devices, discharge with disposable filters, separators and bunkers. Accordingly, they comply with the strict specifications and hygiene standards of the food, pharmaceutical and cosmetics industries.
Technologies for fine grinding
Ebbecke Verfahrenstechnik offers a wide range of processes in the field of contract grinding:
- Spiral jet mill – for high-quality dry micronization
- Fine Mill – for perfect fine grinding (e.g. powder)
- Cryogenic Mill – Cold grinding for temperature-sensitive products
- Drug Mill – for the economical grinding of natural products
- Plastic Mill – for the production of plastic powders
Areas of application
Fine grinding / fine milling is used in many different sectors, including the pharmaceutical industry, the chemical industry and the cosmetics industry. Ebbecke Verfahrenstechnik specializes in the micronization of many different materials with their different properties and requirements. These include, for example, plant-based substances, foodstuffs and plastics. With our fine-mill systems, we can ensure not only the dissolution of agglomerates and the breaking up of solid grain structures in high quality in the field of contract grinding, but also the ultra-fine grinding of materials in reproducible product quality. Our grinding systems can be individually adapted to the specific requirements of the grinding process.
- Fine grinding of products for the production of narrow grain spectra
- Fine grinding of products with dosing of superplasticizers to produce storage stability
- Fine grinding of plastic pellets
- Destruction of agglomerates in crystallized goods
- Fine grinding with sieving or sifting of oversize particles
- Combination with metal detection
- Laser diffraction and moisture measurement in our own laboratory for quality control
- Micronization possible under hygiene standards for food, pharmaceuticals or cosmetics in hygienic operations
Quality assurance for fine grinding
To ensure the quality of the end product, oversize particles can be screened out or sifted out using laser diffraction and moisture measuring devices, among other things. In addition, experts at Ebbecke Verfahrenstechnik check the accuracy of the fine grinding results in the company’s own laboratory and can thus ensure that all quality criteria have been met. Laser diffraction devices, test sieve shakers and air jet sieves are available for this purpose.
For applications in the food, pharmaceutical or cosmetics sectors, special attention must also be paid to hygienic conditions – this is where micronization under hygiene standards comes into play. As part of regular hygiene checks, we sample surfaces and system components and can analyze such microbiological swab samples ourselves in our laboratory in order to permanently check compliance with strict hygiene standards in hygiene processing.
