Description

Technical Field

[0001] The utility model relates to the technical field of mechanical powder sieves, in particular to an annular sieve hammer type crushing device with adjustable centrifugal force and replaceable sieve holes. Background Technique

[0002] With the development of mechanical powder sieves, the annular sieve hammer crusher has been widely used in the technical field of mechanical powder sieves; currently, during the operation of a general annular sieve hammer crusher, the circulating layer formed in the crushing chamber will affect the crushing efficiency of raw materials. The circulating layer refers to the state in which raw materials are jointly affected by the high-speed rotating crushing hammer blades and centrifugal force in the crushing chamber and form a circulating flow state along the inner wall of the crushing chamber. A fixed centrifugal force will result in poor powder screening effect; in addition, different application scenarios have different requirements for the particle size. Different specifications of sieve hole diameters are required during screening, while the existing general annular sieve hammer crusher needs to rely on tools for replacement, which is time-consuming and affects production efficiency.
