Broyeur vertical LM
Based on the absorption of advanced technologies of famous international corporations and 30 years’ experience in grinding mill production, SBM has launched the LM Vertical Grinding Mill which integrates five functions of crushing, affûtage, powder selection, drying and material conveying. It is characterized by centralized technological process, small occupational area, low investment, haute efficacité, energy conservation and environment protection.
caractéristiques du produit: Integration of multiple functions, more stable and reliable production and more excellent capacity
- Taille d'entrée: 0-70millimètre
- Capacité: 3-340TPH
- Matériel: Calcaire, calcite, dolomie, charbon de pétrole, gypse, barytine, marbre, talc, poudre de charbon, etc..
Performance
Less Comprehensive Investment
LM Vertical Grinding Mill integrates crushing, séchage, affûtage, separating and transport. The structure is simple while the layout is compact. Its occupational area is about 50% of that of the ball-milling system. The LM grinding mill can also be arranged outdoors, which greatly reduces the investment cost.
Comprehensive Optimization, Lower Operating Costs
From aspects of grinding efficiency, powder drying, abrasion of vulnerable parts and maintenance & replacement of spare parts, SBM’s LM Vertical Grinding Mill achieves lower energy consumption, stronger drying capacity, as well as lower abrasion and easier checks of core parts, saving the operating costs greatly.
Short Grinding Time & Low Iron Content
The materials linger in the grinding mill for a short time, which can reduce repeated grinding and is easy to detect and control the grain size and chemical component of the product. En outre, the grinding roller and millstone do not contact directly. The iron content in the product is very low, and the iron generated due to mechanical wear is easy to be removed, thus effectively guaranteeing the whiteness and purity of the material.
Greener & More Automated
The operation of LM grinding mill is stable and has small vibration, so that the noise is small. The system is sealed in an integral manner and works under negative pressure, so that there is no dust spilling and the environment can keep clean with the emission standard far better than the international standard. LM grinding mill is also equipped with expert-level automatic control system, which can realize free switch between remote control and local control. The operations are simple and labor-saving.
Traitement numérisé, Une plus grande précision
Il existe des dizaines de lignes de machines-outils à commande numérique. Opérations telles que les plaques d'acier’ Coupe, pliant, rabotage, le fraisage et la pulvérisation de peinture sont tous contrôlés numériquement. La précision d'usinage est élevée, surtout pour les pièces principales.
Approvisionnement suffisant en pièces de rechange, Fonctionnement sans souci
SBM, dont les activités couvrent la production et la vente, assume la responsabilité de chaque machine produite par nous-mêmes. Nous pouvons offrir aux clients des services techniques sur les produits et les pièces de rechange d'origine pour garantir un fonctionnement sans souci..
Principe de fonctionnement
The grinding plate rotates under the action of main motor of LM Vertical Grinding Mill and the reducer. Entre-temps, hot wind enters the vertical mill. After raw materials fall onto the center of grinding plate, they move to the edge of grinding plate under the action of centrifugal force. En passant par la zone de meulage entre le rouleau et la plaque de meulage, les matériaux volumineux sont brisés directement par la pression du rouleau tandis que les matériaux fins forment une couche où les matériaux s'écrasent les uns les autres. Broken materials after grinding continue moving to the edge of grinding plate until they are brought away by the airflow at the air ring. For coarse materials which cannot be brought away would fall onto the grinding plate for another grinding. When passing the upper separator, materials in the air flow will be divided into two parts by the blades of rotor, that is, coarse particles and fine powders. Coarse particles would be sent back to have another grinding while the qualified fine powders enter the powder collector with airflow as finished products. Pour des articles divers comme des blocs de fer dans les matériaux, lorsqu'ils se déplacent vers le bord de la plaque de broyage, en raison de leur poids plus élevé, ils tomberaient dans la cavité inférieure du broyeur et seraient ensuite envoyés dans le port de déchargement par un scarper installé au bas de la plaque de broyage et finalement déchargés hors du broyeur.
