6 ALPINE WET PROCESSING ALPINE AGITATED BALL MILL AHM An agitated ball mill with a horizontal and cylindrical grinding chamber that is universal in use for the continuous wet grinding of particles down to the submicron range. AGITATED BALL MILL AHM PRINCIPLE OF OPERATION OPERATION The AHM is available in sizes suitable for the laboratory, the testing centre or for large-scale production. This agitated ball mill was specially developed for suspensions with good flow properties where a steep particle size distribution and high end-product fineness are demanded. The mill is suitable for both continuous operation and for batch mode in the case of closed-circuit grinding. The product is fed to the mill inlet by means of a suitable pump and exits the mill through a screen at the machine outlet. The grinding chamber is filled to a level of approximately 70-80% with grinding pearls and the purpose of the screen at the outlet is to retain the pearls whilst allowing the milled slurry to exit the mill. Rotating stirrers prevent blockage of the screen. The mills are equipped with stationary or mobile support units that guarantee simple dismantling for cleaning and maintenance. There is sufficient space underneath the grinding chamber to permit the use of large-volume collection bins for emptying and cleaning the mill. PRODUCT INLET PRODUCT OUTLET GRINDING CHAMBER GRINDING PEARL SEPARATION

7 The slotted screen separating element is low-wear in design and is installed in the mill axis. It comprises a screen holder and a slotted pipe screen which can be exchanged easily and quickly without having to empty the mill. Rotating stirrers in the separating zone relieve the screen dynamically and prevent blockages. A robust, double-action mechanical seal with sealing-liquid unit guarantees a high level of operating reliability. WEAR PROTECTION agitator discs, separating rings and stirrers is selected to suit the individual application. Because of this, a long service life can be achieved even if abrasive suspensions are processed. Again, the individual components have been designed with flexibility and cost optimisation in mind. When extremely high demands are placed on the products with regard to contamination, the rotor and stator parts can be coated with either high-grade ceramics or tungsten carbide. The AHM has a cylindrical, double-walled mill housing that can be cooled. The inside of the grinding chamber is lined using sleeve sections in either hardened stainless steel or polyurethane. This modular concept enables rapid exchange of the lining and offers such advantages as inexpensive spares and flexible application possibilities.

8 ALPINE WET PROCESSING ALPINE POWERPAINT DPP This ball mill was specially developed for use in the paint and varnish industry to grind and disperse high-grade water-based and solvent-based paint systems and pigment dispersions. ANNULAR BALL MILL POWERPAINT DPP PRINCIPLE OF OPERATION OPERATION When it comes to the dispersion efficiency, ease of cleaning and cooling efficiency, the Alpine PowerPaint DPP has been designed to fulfil the highest demands. It is suitable for processing solvents as well as suspensions of high viscosity. In addition to applications in the paint industry, the excellent cooling capability and ease of cleaning make the DPP mill well suited to pharmaceutical and foodstuffs applications. The product is introduced centrally into the mill by means of a pump and exits the mill via a rotating slotted screen through the hollow shaft in the upper section of the mill. The geometry of the mill is annular in design and the toroid-shaped gap is filled with grinding pearls. Return channels within the mill are located such that a uniform distribution of the grinding pearls within the grinding gap is achieved at any operating speed, thus ensuring that the separating zone is kept free from blockages. The PowerPaint DPP is characterised by its ease of operation. Main features are the simplicity and speed of emptying the grinding pearls, as well as the ease with which the mill can be dismantled under application of the integrated lifting and swivel unit. The slotted screen can be exchanged without the necessity to remove the rotor. The fact that the mill can be cleaned with a very small amount of a suitable fluid makes for fast enables rapid changeover of products product outlet product inlet mechanical seal circulation channels mill housing rotor cooling grinding gap rotor slotted screen discharge opening cooling Jacket

9 WEAR PROTECTION As a result of the toroid-shaped annular geometry, deflection zones with narrow radii where grinding pearls could possibly block up and cause high local wear are avoided. The optimum motion of the grinding pearls results in a long service life of the machine components, i.e. of the wear-protection elements. A robust, doubleaction mechanical seal with sealing-liquid unit guarantees a high level of operating reliability. Sintered carbide materials ensure excellent wear protection and a long service life. The easily accessible grinding chamber walls and rotor surfaces can also be flame-sprayed with tungsten carbide. The wear-protection materials are characterised by their excellent thermal conductivity; a prerequisite for intensive cooling of the grinding chamber. Powerpaint DPP Grinding bin M o t o r (litres) (kw) 500 DPP 3, DPP 9, DPP Generously dimensioned cooling zones both at the stator and the rotor permit the gentle processing of temperature-sensitive products such as water-based varnishes and lacquers. Over and above this, all productcontact materials are also suitable for operation with solvents. The compact design of the PowerPaint DPP permits an extremely flexible set-up as well as easy integration into existing systems. PROCESS TECHNOLOGIES FOR TOMORROW SM 8 / 9

10 ALPINE WET PROCESSING ALPINE AGITATED BALL MILL DISCOPLEX ADP AGITATED BALL MILL DISCOPLEX ADP The Alpine Discoplex is a ball mill that was specially developed for autogenous grinding, for highly viscous products and for dispersion tasks. The closed-circuit grinding of superfine products is the main application for this mill. PRINCIPLE OF OPERATION The Discoplex is a highly flexible agitated ball mill in terms of it s ease of operation and the wide range of materials of construction available for the wear protection of the grinding chamber and rotor. The construction materials of the stirrers and grinding chamber lining can be freely selected in different combinations. The rotor is disc-shaped in design and has agitators that ensure uniform motion of the grinding pearls. WEAR PROTECTION The two levels upon which the separating element and the grinding pearls are located as well as the internal circulation of the grinding media prevent the grinding pearls from compacting against the discharge screen. The screen can can be installed in any of the different mill designs to be rotating or stationary. The grinding chamber lining can be of tungsten carbide or elastomers. Thanks to their simple form, the stirrers can be made rom a wide range of materials and combined freely with the material used for lining the grinding chamber and rotor.

11 ALPINE ATTRITION MILL ANR The agitated ball mill ANR is an attrition mill in conventional open design. The mill is ideal for grinding mineral powder suspensions of medium viscosity at high outputs. It is used for single-pass grinding in continuous operation. AGITATED BALL MILL ANR PRINCIPLE OF OPERATION The open construction of the ANR permits a robust and simple design that allows large machine sizes to be built. There are neither separating elements nor shaft seals, the result being optimum operating reliability. The open design permits the grinding pearls to be topped up easily during continuous operation. The product is charged to the lower section of the mill by means of a suitable pump and exits the mill via an overflow in the upper section of the mill. Special production parameters ensure that the force of gravity retains the grinding pearls in the mill. The grinding pearls are set into motion by a ceramic-coated agitator. The standarddesign stator is also lined with ceramic to ensure a long service life and to prevent product discolouration. The large-volume design coupled with operation at low speeds permits the production of superfine products at low power consumption. All ANR models can alternatively be supplied with a hydraulic motor. This facilitates mill start-up, permits the speed to be adjusted and makes it possible to use much lower installed motor power values.

12 ALPINE WET PROCESSING ALPINE WET CLASSIFIER HYDROPLEX AHP Long years of experience with classifiers led to development of the Alpine Hydroplex AHP wet classifier. WET CLASSIFIER AHP PRINCIPLE OF OPERATION OPERATION This wet classifier is especially suitable for high-tech products as well as for the separation of relatively small product batches of standard products or products with sensitive surfaces. Typical applications are ceramics, pigments or abrasives. The wet classifier is equally suitable for operation as a stand-alone classifier for pure separation tasks of for operation in circuit with a wet mill. Its flexibility is its forte. The product is pumped into the bottom section of the classifier and is separated into a fine fraction and a coarse fraction by means of a deflector wheel. The fines pass radially through the classifying wheel and exit the classifier via the hollow shaft. The coarse material is discharged from the classifier housing by means of a suitable coarse material pump. The classifier can be opened and dismantled easily by means of the integrated hydraulic lifting unit. Thanks to the modular design, the wear parts are simple and inexpensive to exchange. 100 wet classification of caolin throughput feed fines coarse T (h) 0 0, AHP fineness [µm] (measured with Sedigraph) Parameter: 3500 rpm: AG: 220 kg/h: fines: 115 kg/h: 20 wt% concentr.

13 WEAR PROTECTION The AHP wet classifier can be lined with a number of different wear-protection materials. The wheel can be in ceramic design and the housing can be lined with polyurethane, tungsten carbide or ceramic. The classifier is also suitable for processing solvents. The working range constitutes particle sizes under 200 µm. Cut points of between approx. 2 and 5 µm are possible. The cut point is essentially influenced by the specific weight of the solid. The higher the density, the finer the cut point. Separations are possible with solids concentrations of up to 30% weight. If dispersion agents are used, even higher concentrations can be processed. By varying the speed and throughput rate, the AHP can be employed over a wide particle size range. The end products can thus be optimally adapted to changing market demands. Because of its simple geometry, the AHP is quick and easy to clean and can thus also be employed for different product lines on an alternating basis.

14 ALPINE WET PROCESSING LABORATORY MILL 90 AHM The 90 AHM is the laboratory mill in the AHM series and is designed as a table-top mill with separate control cabinet. LABORATORY MILL 90 AHM PRINCIPLE OF OPERATION WEAR PROTECTION This mill is ideal for small product batches and for development tests, including those in the field of nanotechnology. Extremely small grinding pearls (<0.4 mm) can be used in this mill and tests on the stabilisation of suspensions in the submicron range can be performed. In contrast to the other AHM models, the laboratory version has a variable-speed direct drive and a generously dimensioned flat screen deck. To permit filling and emptying, the mill is suspended in pivots on a frame. The upright position also allows a cleaning of the screen without emptying the mill. The wear parts of the basic machine are exchangeable and can be made of stainless steel, ceramic, tungsten carbide, polyurethane or other plastics. OPERATION The high degree of flexibility results from the possibility of equipping the mill with grinding bins and agitator shafts in different lengths. This makes it possible to adapt the mill to different grinding bin volumes and to process batches of 250 ml, 500 ml and 1100 ml. Clamp rings guarantee ease of cleaning and dismantling. A high degree of operating reliability is achieved with the double-action mechanical seal.

15 GRINDING PEARLS, TECHNOLOGY AND CONSTRUCTION MATERIALS GRINDING PEARLS Besides the mill design, there are a number of other factors that make a major contribution to the success of a grinding process, namely the type of grinding media used, the wear-protection materials, the separation of the grinding pearls and naturally also the process as a whole. WEAR-PROTECTION MATERIALS We use a variety of different materials to line our mills if highly abrasive products are being ground. To guarantee a long service life, we employ high-grade polyurethane, selected steels or ceramic materials, as well as coatings with tungsten carbide or other materials that have a favourable influence on the grinding process. GRINDING PEARL SEPARATION The fact that the grinding pearls do not compact together is an important advantage with all our mills. With the AHM mill, rotating pins ensure that the batch of grinding media remains loose and separate around the screen, whereas with the ADP and the DPP, it is the special mill geometry and the subsequent circulation of grinding pearls that ensures smooth and trouble-free operation. The rotating screen in these mills also brings an additional optimisation in the case of highly viscous products. GRINDING MEDIA We work with a selected number of reputable grinding media manufacturers who we have no hesitation in recommending. The quality of the grinding pearls is extremely important for the entire grinding process and a prerequisite for trouble-free mill operation, because abraded media particles can naturally adversely affect the end product. There are grinding pearls (material, size, etc.) to suit every grinding process, and we work in close cooperation with our customers to ensure selection of the ideal media for their application ALPINE COMPLETE SOLUTIONS Alpine has many years of experience in engineering complete wet systems to suit your individual requirements and wishes, and also offers turnkey solutions upon request.

16 ALPINE WET PROCESSING SYSTEM EXAMPLE: ENGINEERING CERAMICS WET GRINDING OF HARD MATERIALS Optimum wear protection and suitable grinding pearls ensure that these mills have a long service life. The two illustrated AHM agitator ball mills are generally operated independent of each other in closed-circuit mode. The selected configuration, however, is so flexible that these mills can also be series-connected. This brings advantages if different products are being processed and also offers redundancy with respect to the availability of the grinding system. The suspension is mixed in a bin before being pumped by a hose pump through the mill and back into the bin again. Over the running time of the grinding operation, this results in a specific number of theoretical passes through the mill that influence the grinding process. We also offer different options as regards the system control. Dependent on customer requirements, a PLC unit with different control circuits can be installed to monitor the entire system. Our control systems can be designed for incorporation into existing systems, enabling monitoring of our process at the central control station. Ask us about the various options!
