Vertical shaft impact crusher central shaft iron stone mixing chamber

Abstract

The invention discloses a central axis type iron and stone mixing cavity in a vertical shaft impact crusher. The mixing cavity is characterized in that the height of an anvil in the central axis type iron and stone mixing cavity is 20% to 70% of the height of a rotor throwing channel, the central line of the height of the anvil basically coincides with the middle axis of the normal distribution of the thrown crushing material, on the circumference corresponding to the material thrown by a rotor, an L-shaped ring shape is defined by a steel plate still, and the anvil is encircled by the L shape. The cavity achieves the crushing effect close to the stone beating iron cavity, the whole crushing production line can exert all capacity of other machine devices, the final product yield is improved, the output ratio of final products is improved, and the ratio is more reasonable. The on-site adjustment height, and the front and back position are provided, the height, the thickness and flexibility of the front and back position are subsequently adjusted, and flexible conversion between cavities can be achieved according to different sites and different conditions.

Description

technical field [0001] The invention relates to a vertical shaft impact crusher, relates to the form of a cavity in the middle of the vertical shaft impact crusher, and particularly relates to a shaft type iron-stone mixing chamber in the vertical shaft impact crusher. Background technique [0002] The vertical shaft impact crusher is a crusher that uses a completely different working principle from the traditional crusher. The impact rotor rotates at a high speed of about 1500 rpm, and the linear speed of the rotor edge reaches a speed of more than 60m / s. The material is fed from the center. , by accelerating the crushable material to a speed of up to 60m / s, hitting the iron wall lining or stone wall lining to achieve the purpose of crushing the crushable material, which is heavier than the "vertical hammer breaking" that is difficult to increase the speed when falling from one side Or the effect of "vertical anti-breaking" is much better, especially for small and medium-si...

[0008] There are also some cavity designs on the market. An anvil is placed at the rear of the L-shaped stone-lined cavity. The purpose is to install and remove the anvil through the anvil, and to switch between the two cavity types of "stone-on-iron" and "rock-on-rock". , such a design, the cavity transformation is more convenient, but the disadvantages are also obvious, and its "stone striking iron" effect is weakened, because in other designs where all the anvils may be used, the middle and lower parts of the anvil in this cavity are lined with stones. The "buried" is still only the effect of "rock hitting rock". The use of the anvil is not sufficient. Basically, the lower half of the anvil is not worn, and the upper part is less worn. very big
