Hammer mills and lump breakers, also known as lump crushers, are machines used in material handling systems across a wide range of applications. Many industrial sectors require particle size reduction for the processing of material—minerals and mining, cosmetics and pharmaceuticals, agricultural and food manufacturing, pet foods and plastics, and so on. In processing material, particle size reduction may be necessary to increase the surface area of material, increase dissolution or absorption rates, improve pneumatic conveyance, achieve greater uniformity, or to provide effective drying and mixing of the material.
Though both lump breakers and hammer mills provide solutions for particle size reduction of materials, each is designed to fulfill different application requirements. This relates to the concept of size reduction, which varies depending on the processing needs of the material itself. Even though the common denominator is the reduction in size—the crushing, grinding, pulverizing, shredding, de-lumping, or milling of material is accomplished by utilizing specific equipment that emphasizes a unique mechanism to break the product into smaller pieces.
Cómo procesa los materiales cada máquina
Hay diferencias clave en la aplicación de los trituradores de trozos y los molinos de martillos. Dependiendo de las necesidades de procesamiento, uno puede ser más eficiente o más económico que el otro. Para entender las diferencias entre ambos, veamos con más detalle qué es cada uno y cómo funcionan.
Rompedores de Lápices
Lump breakers are used to break apart granules and powders that have agglomerated or formed lumps as the result of weak cohesive forces between individual particles. Lump breakers crush these lumps with specially shaped blades housed within its housing. The rotation of these blades through stationary, fixed combs applies sufficient impact and compression force to efficiently break lumps of agglomerated material fed through an opening in the top of the unit. The process continues until the material is reduced in size sufficient to pass through a screen at the discharge of the unit.
Los rompedores de grumos son importantes en el procesamiento de materiales que tienden a aglomerarse y agruparse durante el almacenamiento o el transporte. Esto es común en el cemento, los fertilizantes y los productos químicos en polvo que se encuentran en las industrias pesadas, pero también en los productos alimenticios como el azúcar, las sales, las tripas de alimentos y las barras de granola. De hecho, cualquier tipo de material seco, granulado, fino o en polvo que tenga tendencia a absorber la humedad resultante de la misma, probablemente se apelmazará cuando se almacene. Romper los grumos del material en su tamaño de partícula original y uniforme permite una manipulación más fácil y un procesamiento posterior.
Molinos de martillos
A diferencia de un rompedor de terrones, un el molino de martillos está diseñado para triturar, moler, pulverizar y hacer añicos partículas individuales de material sólido. La reducción uniforme del tamaño de las partículas de la materia prima se produce mediante golpes repetidos de martillos móviles sujetos a un eje giratorio alojado en el interior de la cámara del molino. Una vez que el material se introduce en la cámara, los martillos oscilantes impactan y aceleran las partículas, que chocan contra las paredes de la cámara y entre sí. Los impactos y colisiones se repiten hasta que las partículas individuales son lo suficientemente pequeñas como para pasar a través de una criba situada en el fondo de la cámara.
Whether pepper, coffee beans, coal or asphalt, hammer mills can effectively shatter, grind, shred, crush or pulverize any raw material to a desired outcome through repeated impact. The resulting particle size is not only determined by screen size, but also the hammer tip speed, thickness and quantity of hammers, and their uniform configuration, or pattern as distributed around the circumference of the rotor.. For example, reducing stones to a fine size would require a high shaft speed with balanced symmetry, a smaller screen, and a high number of hammers.
La diferencia entre las trituradoras de grumos y los molinos de martillos
As mentioned, lump breakers are designed to reduce agglomerated particles, whereas hammer mills are used to break down individual particles into smaller sizes. A lump breaker gently crushes and pulverizes fine material that has agglomerated or densified due to environmental conditions in the course of transportation or storage. A hammer mill operates with extreme power, efficiency and higher impact force to reduce bulk solids to a uniform particle size.
Lump breakers and hammer mills are each used for particle reduction of material. Both are robust machines that are utilized to process large materials into smaller materials for easier handling and further processing. However, they function in different ways. The key difference between them is related to their respective application methods which in turn, is related to the type of material being processed. Whether the material requires the gentle impact of a blade or the forceful impact of a hammer will determine which application, the lump breaker or hammer mill, is best suited for the processing requirements of the material.
