Dual-roller dual-cavity three-impact crusher

Abstract

The invention provides a dual-roller dual-cavity three-impact crusher, mainly composed of a feed hopper, a case shell, a crushing roller, a fine crushing roller, a crushing hammer and a fine crushing hammer. The crusher has the structure characteristics that: 'a swing tooth plate is provided to form a crushing operation cavity, an upper drag rod and a lower drag rod are provided to form a fine crushing operation cavity, and a group of impact rod and fixed tooth plate is arranged' in the case shell, thus forming three-impact crushing structure; the crushing operation cavity and the fine crushing operation cavity form natural and smooth 'material flow grade'; and 'a distributary window is provided and an assistant feed bin is arranged' at the rear end of the case for effective charging and distributary, so that the crusher not only can carry out series processing operation of rough crushing, intermediate crushing and even fine crushing on medium and high hardness block materials but also can carry out crushing processing operation on wet ore-rock material containing much mud and high moisture, improves conformability to crushing material, has the advantages of low power energy consumption, high production efficiency and being capable of effectively prolonging the service life of hammer wearing part, and has excellent market prospect.

Description

Technical field: [0001] The present invention relates to a hammer crusher, in particular to a double-roller, double-chamber, three-strike crusher, which is especially suitable for crushing pebbles, iron and steel waste, quartz ore Coarse crushing, medium crushing and fine crushing of high-hardness materials such as basalt, copper-vanadium-nickel ore, and medium-soft and hard materials such as rocks with high water content. Background technique: [0002] In the process of industrial production, in order to meet the technical requirements of the process regulations, it is often necessary to decompose and crush the larger hard raw materials until they are finely crushed. This production requirement objectively promotes the further development of crusher products. and development work. Although there are various specifications and models of crusher products on the market for users to choose and use, it is needless to say that most of the current crusher products have single fun...

Problems solved by technology

However, its production efficiency is low, and the cost of crushing and processing operations is high.

Especially the current crushers commonly used in chemical, cement, brick-making and other industries, when performing fine crushing operations on medium-soft and hard wet materials, often show that the crushing operation is difficult, the wearing and wearing parts of the hammer head are fast, The use defects such as low processing efficiency and high production and operation costs, if the proportion of silt and sand in the medium-soft and hard wet materials is large and the water content (volume ratio) reaches 30%, the phenomenon of clogging and blocking the paste roller will also appear in the machine case. In severe cases, it will not work normally and can only be forced to stop production, which will have a serious impact on the production and work order
