The main parameters of hammer crusher include linear velocity, production capacity and motor power.
Linear velocity
Linear velocity selection for the impact hammer crusher is determined based on material properties, crushing ratio, machine structure, and also takes into account the wear grade of the hammer head. A higher linear velocity enhances the impacting speed, providing more opportunities to strike materials, which aids in achieving finer product granularity and improving production capacity. However, excessively high linear velocity can hinder material entry into the striking zone, increase hammer head wear, and reduce energy utilization efficiency. Conversely, reducing the linear velocity decreases hammer head wear but increases wear on the hammer dish. Therefore, the selection of linear velocity requires comprehensive consideration. Given that it is influenced by cutting action as well as hammering and grinding between the hammer head and grizzly bar, an appropriate range is 30-40 m/s.
Production capacity
There are numerous factors that influence production capacity, including crushing ratio, rotational speed, material physical properties, particle size distribution, machine structure, and others.
Motor power
The power requirement is influenced by several factors including material properties, crushing ratio, processing capacity, and the impact of rotational inertia of the rotor during the initial phase when the hammer is asymmetric.
