PENDULUM ROLLER MILLS

WIDE APPLICATION'S VARIETY

 

The pendulum roller mills BRASPROCESS MP Series are indicates to grind several of solid materials, with a wide application range. However, observe that the acceptable products must be preferably in the hardness range over 40 of the Hardgrove grindability index (for mineral coals and/or charcoals, petroleum coke or other possible solid fuels), and/or below 6 in the Mohs Scale (for non-metallic mineral in general or manufactured substances) with moisture in feeding, in terms of the specific product processed, which may be over 20%, such as in the particular case of charcoal breeze, with feeding granulometry up to 30 mm, obtaining a pulverized product 99,99% passable from mesh 60, to 99,99% passable through Tyler 325 (44 microns) mesh or even finer meshes; according to the pre-selected classifier.

In order to process materials with high contents of initial moisture, the roller mills are dimensioned in terms of thus moisture, and not only in function of the initial and final granulometry desired for a given grinding capacity.

The basic feature of the grinding with pendulum roll grinders BRASPROCESS is the performance with low power consumption and disregardable noise level, thus enabling to achieve medium to superfine granulometries by selecting the classifier integrated to the grinder, in addition to its high operational reliability in productive chains, with continuous and severe utilization

 

 

   
 
   

PENDULUM ROLLER MILL

 

This is a well-known grinding concept, which for decades consolidated a successful performance. By keeping the grinding principle and leveraging the technological evolution occurred, its mechanical construction has been an object of on-going technical innovation, aiming at maximizing its productivity and reducing even more its low power consumption, in addition to support more and more the market needs for mineral loads, formulations or solid fuels.



EQUIPMENT SELECTION

The first factor to be considered when selecting the grinding system is correct characterization of the mineral/product to be processed. The capacity required from the system, and primarily from the grinder, depends on the material type, its
crystalline structure and size, hardness and friability, abrasiveness, density, presence of foreign contaminant bodies, origin, granulometry of the raw product, eventual moisture, and finally , the granulometry of the pulverized product desired, as much as possible, according to the Tyler
screen standards. In case of moisture in the raw product,
it shall be informed whether or not this must be removed, as well as the percentages to be achieved in terms of the grinding systems feeding conditions and the residual value in the pulverized product.

 

 
   
   

“THE MACHINE”

 

 

The pendulum roller mill BRASPROCESS MP Series
incorporate the technical enhancements
recently occurred and their electromechanical
construction enables to grind, classify, dry retain
and expel impurities; dosage, aggregate
and mix continuously and simultaneously,
by its integrated circuit.


 

 

 

 

 

 

 

The more information you can check on the material, the more accurate will be the grinder dimensioning, and the more adequate will be the auxiliary equipment. When applicable, additional information on product particularities, such as abrasiveness, explosiveness, unctuousity, softening point, will be always very useful.
   

CAPACITIES

The Pendulum Roller Mill BRASPROCESS MP Series is comprised by 7 standardized models, and as previously mentioned, the actual productivity depends on several factors; however, assuming that the unit dimensioning shall be confirmed by the Engineering Dept. at BRASPROCESS.

COMPARATIVE ADVANTAGES

Once the grinding capacity and product are defined, the grinder and the complementary equipment are specifically selected. The products to be improved frequently present critical or variable characteristics, with strict limitations that require additional cautions. In this aspect, and in order to maximize the unit productivity, prevent interruptions by events no expected in the project or reduce downtime and increase the lifetime of wearable parts, it is important to identify the particular product characteristics that influence on system performance. We highlight below the comparative advantages offered by the grinder, aiming at its maximum efficiency.
