Problems solved by technology

However, although this device also adopts secondary crushing treatment, the two crushing processes are all carried out through the crushing shaft. For some minerals input into the crushing box, while crushing, the crushing shaft at some positions cannot be accurately located. As a result, local minerals cannot be crushed, resulting in low crushing quality and low crushing efficiency

Embodiment 1

[0019] see Figure 1-3 , an environment-friendly crushing device for primary processing of minerals, comprising a base 10, a bracket 11, a feed inlet 13, a primary crushing cavity 18, a secondary crushing cavity 26, and a discharge port 32; the bracket 11 is fixedly installed on the left side of the base 10 On the top, the right side wall of the top of the bracket 11 is fixedly installed with a horizontal bar 12, and the right end of the bar 12 is provided with a feed port 13 for minerals to enter downwards, and the bottom of the feed port 13 communicates with a primary crushing chamber downwards. 18. A set of hammer plates 33 are arranged inside the primary crushing chamber 18 , and the bottom of the hammer plates 33 is provided with a corrugated structure to increase the friction between the bottom of the hammer plates 33 and the minerals inside the primary crushing chamber 18 . The top of the hammer plate 33 is fixed with a vertical telescopic rod 14, and the top of the tel...

Embodiment 2

[0024] On the basis of Embodiment 1, a buffer chamber 23 is fixedly installed, and a group of pressing plates 35 are arranged inside the buffer chamber 23. A group of vertical telescopic rods 14 are fixedly connected through the connecting rods. By setting a buffer chamber 23 between the hammer plate 33 and the telescopic rods 14, the buffering part can be slowed down when the hammer plate 33 touches the bottom of the primary crushing chamber 18 in an instant. impact force to protect the hammer plate 33 and the primary crushing chamber 18 for safe use.

Abstract

The invention relates to the technical field of mining machinery, and discloses an environment-friendly crushing device for mineral primary processing. The environment-friendly crushing device comprises a base, a bracket, a feeding inlet, a primary crushing cavity, secondary crushing cavities and a discharging outlet; a set of hammering plates is arranged in the primary crushing cavity, vertical telescopic rods are fixedly mounted at the tops of the hammering plates, fixed blocks are fixedly mounted in the middles of the telescopic rods, driving rods are fixedly mounted on the left side facesof the fixed blocks, the left sides located in the middles of the telescopic rods are provided with a set of vertically-placed mounting discs, two sets of pushing rods are fixedly mounted on the upperparts and the lower parts of the right side faces of the mounting discs, and transverse rotating rods are fixedly mounted in the middles of the left sides of the mounting discs; and two sets of discharging nets are arranged on the lower parts of the left side wall and the right side wall of the primary crushing cavity, the exteriors of the discharging nets communicate with obliquely downward discharging pipes, the bottoms of the discharging pipes communicate with the secondary crushing cavities, and crushing shafts are arranged in the secondary crushing cavities. The environment-friendly crushing device has the advantages of secondary crushing treatment, comprehensive crushing, high quality, high efficiency and good environmental protection property.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to an environment-friendly crushing device for primary mineral processing. Background technique [0002] Machinery directly used for mineral mining and beneficiation, including mining machinery and mineral processing machinery. Broadly speaking, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, fans and drainage machinery are also used in mining operations. Mining machinery includes mining machinery for mining metal ore and non-metallic ore. [0003] Chinese patent (notification number: CN 206897546 U, announcement date: 2018.01.19) discloses a dual-type high-efficiency crushing device for mineral mining, including a primary crushing box and a secondary crushing box. There is a material inlet on the top, and a hopper is arranged on the material inlet. The first crushing shaft, the second crushing shaft, the third cru...
