Particle size adjustable ore crusher

Abstract

The invention relates to the technical field of ore crushers, in particular to a particle size adjustable ore crusher. The particle size adjustable ore crusher comprises a supporting seat, wherein a crushing box is arranged on the upper end face of the supporting seat, a box cover is arranged at the upper end of the crushing box, and a feeding hopper is arranged on the left side of the upper end face of the box cover; a crushing barrel is arranged inside the crushing box, and the outer side of the crushing barrel is sleeved with an adjusting sleeve; crushing rods are uniformly arranged on theinner side wall of the crushing barrel; the crushing rods penetrate through the side wall of the crushing barrel to be sleeved with a baffle, the outer side of the portion, between the baffle and theouter side wall of the crushing barrel, of each crushing rod is sleeved with a first spring, and wedge-shaped plates are evenly arranged on the portions, corresponding to the crushing rods, of the inner side wall of the adjusting sleeve from top to bottom; and adjusting screws are uniformly arranged on the upper end face of the adjusting sleeve, and the other end of each adjusting screw penetratesthrough the box cover to be sleeved with an adjusting nut. The particle size adjustable ore crusher has the advantages that the crushing particle size can be adjusted, and the crushing efficiency ishigher.

Description

technical field [0001] The invention relates to the technical field of ore crushers, in particular to an ore crusher with adjustable particle size. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be utilized. Can be divided into metallic minerals, non-metallic minerals. The unit content of useful components (elements or minerals) in ores is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are usually expressed in percentages. The ore grade is often used to measure the value of ore, but the composition and harmful impurities of the gangue (useless minerals in the ore or minerals with very little useful content that cannot be used) and harmful impurities in the ore also affect the value of the ore. [0003] With the continuous development of the existing industry, the crushing output of the existing ore crusher i...

Problems solved by technology

[0003] With the continuous development of the existing industry, the crushing output of the existing ore crusher is the focus of the crusher at this stage. However, although the output has been increased, many problems have appeared as follows: the distance between the crushing hammer and the crushing cylinder Unable to adjust, the discharge particle size cannot be adjusted, the gap of the filter plate is too single, the filter plate cannot be replaced as needed, and the crushing efficiency is low
