Double-cavity compound-pendulum jaw crusher for ore crushing

Abstract

The invention relates to a double-cavity compound-pendulum jaw crusher for ore crushing. The double-cavity compound-pendulum jaw crusher is characterized by comprising a rack and an adjustable feeding hopper installed at the upper end of the rack, wherein the size and position of the feeding hopper are both adjustable; two independently-driven movable jaws are symmetrically arranged below the feeding hopper, and are connected with a motor drive device for driving the two movable jaws to carry out a compound-pendulum motion independently; a fixed jaw is arranged between the two movable jaws, and is fixed on the rack; two independent crushing cavities are formed between the two movable jaws and the middle fixed jaw; a discharge port is arranged below the fixed jaw; a material separation anvil for separating ores to the left crushing cavity and the right crushing cavity is installed on the symmetry axis of the two movable jaws at the top of the fixed jaw; the two movable jaws are connected with movable jaw adjustment mechanisms with the same structure respectively; and a detection door and an observation hole are further arranged in the rack. The double-cavity compound-pendulum jaw crusher disclosed by the invention has the advantages of being efficient, high in yield, easy to manufacture, high in applicability, flexible to operate, capable of guaranteeing a discharge granularity, and the like.

Description

technical field [0001] The patent of the invention belongs to the technical field of material crushing and grinding in various industries, and is especially suitable for the field of ore crushing, in particular to a double-cavity compound pendulum jaw crusher for ore crushing. Background technique [0002] The jaw crusher has a wide range of applications and can crush all materials that meet the adaptability requirements, such as limestone, sandstone, iron ore and other materials, and is mainly used for coarse crushing operations. [0003] In recent years, with the rapid development of infrastructure, the aggregate industry has gained momentum, and new large-scale sand and gravel aggregate yards have sprung up across the country. Natural sand and gravel aggregate is a non-renewable, indispensable and irreplaceable natural mineral resource, and it is close to exhaustion, and environmental protection does not allow it to be exploited in large quantities. Compared with natural...
