Description

A fine impact sand making machine

technical field

The invention belongs to the technical field of sand making machines, and in particular relates to a fine impact sand making machine.

Background technique

With the acceleration of economic construction and social development, the demand for sand is also increasing, and the phenomenon of indiscriminate mining of river sand continues to appear, and various places have also adopted measures to prohibit mining. Therefore, artificial sand making machines should be used And born. In the field of mining equipment, the application of impact sand making machines is very common. Its working principle is to throw rock materials into the sand making machine. After entering the sand making machine, the rock materials are divided into middle throwing materials and surrounding blanking materials. ,The main shaft group of the sand making machine drives the impeller to rotate at a high speed, and the thrown material in the middle is hit and thrown at a high speed and hits the surrounding blanking material and the lining plate inside the sand making machine, so as to obtain crushed sand making raw materials.

However, the existing impact sand making machines still have the following deficiencies in the actual use process: First, because the existing sand and gravel raw materials are all of different particle sizes, the existing impact sand making machines all use an impeller to Sand and stones of different sizes are mixed together and rotated and accelerated to throw them, so that they collide with free-falling sand and stones. Although the sand and stones with larger particle sizes can be crushed, the same is true for smaller particles. Throwing out at a very high speed causes the materials with smaller particles to collide with the free-falling gravel and the crushing plate to be excessively crushed, so that excessive dust and smoke are generated during the high-speed rotation of the impeller, which not only causes the raw materials to be over-pulverized, but also destroys the The production environment of the sand making machine; secondly, the traditional sand making machine uses the throwing device to collide the side throwing of the sand in the middle with the falling rock and break it. , and will not repeatedly collide. For some larger or harder raw materials that are difficult to crush completely, these raw materials will directly fall into the outlet at the bottom and be mixed with the finished product directly. The finished product needs to be filtered and screened later. , resulting in poor sand making effect.
