Efficient powder coating processing

Powder coatings are solvent-free coating substances which are used in the high-quality industrial coating of surfaces. Requirement: easy cleaning, constant particle size distribution!
The basic principle of operation has hardly changed since the 1960s. By optimising our grinding and classifying technologies, we have always kept pace with the increasing quality requirements.

Grinding powder coatings with classifier mills from the ACM product line

The classifier mills ACM were developed to do justice to the often-voiced demand for minimal cleaning times in the production of powder coatings. The ACM EC (Easy Clean) and EC-CL (Classifier Direct Drive) are tailored to exactly these requirements. The use of the new E3 beaters achieves throughput increases of up to 20 % when compared to your current ACM classifier mill. Energy savings mean you can reduce your production costs to a minimum.

For demanding special products: high-efficiency cyclone-classifier (HECC) makes change-over from cyclone to classifier operation possible
For the dedusting of powder coatings containing titanium dioxide: TSP fine separator ensures maximum selectivity and thorough cleaning

ACM system for manufacturing powder coatings

with a cyclone-classifier (optional) and cyclone

ACM EC-CL

particularly easy to clean

The ACM EC (Easy Clean) was developed to meet the demands for minimum cleaning times. The mill housing is designed as a double chamber system. This means that 70 % of the parts can be easily removed for mill loading without tools.

Advantages of the new design:

Easy and quick change of the parts of the mill equipment to be cleaned
80 % time saving during cleaning
Maximum accessibility
Cooling zone to reduce product buildup
Sound reduction

The cyclone classifier for efficient dedusting

change easily and flexibly

Alpine Classifier HECC

The high-efficiency cyclone classifiers (HECC) unite maximum coarse yield at efficient dedusting in classifier mode as well as optimised collection rates in cyclone mode.

Advantages of cyclone classifiers

automated lifting-swivelling device
Simple change between classifier and cyclone mode
No internal fittings and thus easy and fast cleaning

Advantages of cyclone classifiers in operation

Stepless reduction of the fines portion
Narrow particle size distribution
High precision of cut

The ultrafine classifier for maximum dedusting quality

for powder coatings containing titanium dioxide

Alpine Air Classifiert TSP

The TSP air classifier was specially designed for demanding classifying tasks. In addition to the highest selectivity, the focus was on aspects such as handling, safety as well as operating and installation costs.

All benefits at a glance

The critical fine fraction of <10 µm is <1% after the classifing process with the TSP
Product flow without back-mixing ensures a high quality of dedusting
The hinged housing enables optimal accessibility

Quick and easy cleaning when changing products minimizes downtimes
Especially suitable for toner and pigment sifting as well as for dedusting powder coatings containing titanium dioxide
Maximum precision of cut
