Description
The present invention relates to a cone crusher of a modified structure, and more particularly, having a multi-stage mantle, multi-stage concave characterized in that to increase the fracture effect by installing a plurality of impact bars for each stage of the multi-stage mantle An impact cone crusher of the structure.
The demand for aggregates required at various construction sites is increasing, and various production machines for obtaining the aggregates are also proposed.
Jaw crusher is a device in which raw stone enters and breaks between the fixed plate and the moving jaw. The jaw crusher is determined according to the size of the jaw, and the gap between the fixed plate and the copper plate It is a grinding machine that determines the size of aggregate produced by adjusting, and roll crusher is a device that rotates two rolls in opposite directions and puts stones between them to adjust the size of aggregate by adjusting the gap between two rolls. The impact crusher is a crushing machine that is crushed by a shock plate installed in a cylinder that rotates at high speed at several tens of m / sec. It is mainly used to remove the mortar and paste from the waste aggregate. .
Construction wastes generated in various construction works and road works are shredded to a proper size using a hammer crusher at a collection site and transported to a treatment facility. Cone crushers are used to shred aggregates that have been primary shredded using, and primary shredded from jaw crushers to smaller particle sizes if necessary.
Cone crusher is the aggregate that passes through the input hopper and the mantle disposed at the bottom of the input hopper is rotated by concentricity or eccentricity, and the aggregate is passed through the gap between the cone cage formed at the outer wall of the mantle and the mantle. It is a production apparatus for obtaining smaller fine aggregates by being crushed and crushed.
In general, the distance between the mantle and the concave in the cone crusher has a structure of the upper and lower straits, which are gradually narrowed downwardly. By sticking can further increase the crushing and grinding effect, on the other side, the gap between the mantle and the concave is further increased, the aggregate falling to the part has a problem that the crushing effect falls.
As a result, among the aggregates that pass through the cone crusher, there is a large amount of aggregates that are crushed and crushed again so that the aggregates are re-injected into the mantle. Repeatedly occurring process has had a problem that the effective aggregate crushing and grinding is not made smoothly.
In addition, the conventional corn crusher had the problem of replacing the mantle by tearing off the whole corn crusher, including the concave, in the process of crushing and crushing the aggregate while eccentric rotation, if the mantle cracks or needs repair, When the amount of aggregate that enters through the input hopper has a problem that the lack of force to crush the aggregate can not perform the role of crushing and grinding properly.
In addition, in the conventional corn crusher structure, only the aggregates produced were not easily removed and the aggregates were crushed to give recognition of poor materials due to paste problems. It only shows the effect of crushing aggregates below the appropriate size using jaw crushers, but in order to remove the mortar paste components attached to the crushed aggregate raw materials, a separate separator must be used to remove and deliver the mortar paste components. There have been problems such as being returned or recalled as a bad material by omission of the material. Providing high quality recycled aggregates requires the use of the mortar paste ingredients to make the best quality aggregates with the minimum time, effort and equipment. How much can you get rid of? Even if it is not an exaggeration.
When the impact crusher is introduced into the hopper, the injected aggregate is guided to the center of the impact rota by the feeding of the impact rota, and the guided stone is sprayed by the spray cone provided at the bottom of the center of the impact rota and evenly distributed inside the impact rota. When the impact rota rotates and the embedded gemstone is strongly sprayed to the outside by centrifugal force, the aggregate that is bounced out to the outside is hit by an anvil installed coaxially with the impact rota, and is broken into a chute that is a lower hopper. As a device for crushing and crushing aggregate by falling, it is a device that gives the function and effect that can effectively peel off the mortar or paste, which is foreign matter adhering to the aggregate by hitting the aggregate strongly.
The present invention is to provide a structure that combines the advantages of the conventional crushing mantle with the eccentric rotating mantle and the advantage of the mortar removal function of the impact crusher in one device, it can be crushed and crushed most of the input aggregate The purpose of the present invention is to provide an impact cone crusher having a multi-stage mantle structure that can effectively remove foreign substances such as mortar / paste adhered to the aggregate.
The multi-stage mantle provides an impact-type cone crusher having a function of striking and crushing the aggregate over the entire area from the top to the bottom of the mantle, while also allowing impact bars to be installed at each stage. It has a purpose.
In order to achieve the above object, in the present application, a plurality of impact bars are installed in each stage in a mantle composed of multiple stages, so that aggregate aggregates are hit by the impact bars installed in the mantle and collide with the concave so that crushing and grinding can occur simultaneously. Disclosed is a technical idea of an impact cone crusher.
In particular, the technical concept of an impact-type cone crusher that divides the conical mantle into multiple stages and installs an impact bar for each stage can be hit by the impact bar for the most input aggregate.
The impact cone crusher with a multi-stage mantle provided herein can achieve the effect of mixing the functions of the conventional cone crusher and the impact crusher two functions in one device structure, so as to crush and crush the aggregate raw material, It provides an effect that can effectively remove foreign substances such as paste.
In addition, in the present application, the mantle is divided into multiple stages, and various types of impact bars are installed at each stage, so that the impact bar can be crushed and crushed evenly by allowing the impact bar to fall to either the center or the outside of the mantle. It will have an effect.
