The function of the material distribution cone of the VSI sand making machine:
The material distribution cone is also called bulk material cone, material distributor, material distribution plate, distribution cone, etc. It is one of the indispensable accessories in the crushing device of VSI series new type sand making machine (VSI impact crusher). The material of the sand machine is evenly dispersed in the impeller to realize the reasonable distribution of the material, prevent uneven wear of various parts, and ensure the smooth operation of the sand making machine and the quality of the finished sand.
VSI sand making machine can be divided into "rock-on-rock" and "rock-on-iron" crushing principles according to the feeding method. The distributing cone of the impact crusher is installed on the upper part of the vortex crushing chamber, and the function of the distributing plate is to divide the incoming material from the feeding hopper. Stone-to-stone adopts a waterfall flow distribution system. The material falls into the hopper of the sand making machine, falls through the annular hole, and is divided into two streams by the material distribution cone: a part of the material directly enters the impeller through the central feed pipe and is gradually accelerated to a higher speed. Ejected at high speed, a part of the material enters the outer side of the impeller in the vortex crushing chamber from the outside of the central feeding pipe, and finally the two paths of material collide strongly in the area of the impeller, resulting in rock-on-rock crushing.
"Stone iron" is to introduce all the materials into the impeller cavity, and after the impeller accelerates, it is thrown out, and the metal impact plate on the inner wall of the equipment is collided to achieve the crushing effect. By adjusting the ratio of center feed and edge feed of the distribution cone, the flexible conversion between sand making and shaping of the VSI sand making machine can be realized.

The material and life of the distribution cone:
There are many kinds of materials of the material distribution cone, the common ones are high manganese steel, high chromium alloy steel, austenitic wear-resistant manganese steel, new composite materials, etc. In particular, the new type of wear-resistant ceramic sand making machine material distribution cone uses special toughened ceramic composite materials to replace the traditional manganese steel and poured alloy parts, which greatly improves the wear resistance of the impact block and the crushing capacity of the sand making machine, and the service life is increased by 3-6 times.
As a common wear-resistant and vulnerable part of impact sand making machine, the consumption is relatively large, and the selection of high-quality wear-resistant material cone can well ensure the actual production and application of sand making machine equipment and extend the service life of the impact sand making machine material cone.

Advantages of wear-resistant ceramic distribution cone:
1.Wear resistance, long service life: the main factor that determines the wear resistance of materials is the hardness of the material, the hardness of wear-resistant ceramics is as high as HRA85 or more, far beyond high chromium cast iron, strong wear resistance, compared with high chromium cast iron cone, 95 alumina ceramic cone service life is extended by 3 times, ZTA ceramic cone service life is extended by 6 times, which can greatly save costs, reduce the number of replacement and maintenance, and improve production efficiency.
2.Dust suppression and noise reduction: Due to the characteristics of the material, the wear-resistant ceramic distribution cone also has the effect of suppressing dust and reducing noise.
3.Impact resistance of ZTA ceramics: During the working process of the sand making machine, the distributing cone will be continuously impacted by crushed stones, etc. ZTA wear-resistant ceramics produced by KINGCERA are also called zirconium-aluminum composite ceramics. Composed of aluminum and zirconia, it has both the high hardness of alumina ceramics and the toughness of zirconia, which is both wear-resistant and impact-resistant.

As a professional manufacturer with more than 30 years of R&D and application of special ceramic materials, KINGCERA Ceramics has achieved independent production and quality control in the whole process from raw material import, powder grinding, green tape molding, kiln sintering to fine processing.
The wear-resistant ceramic powder cone produced by KINGCERA, the alumina powder is imported from Australian , and special ingredients such as zirconia are added according to the unique formula of KINGCERA, and the spray granulation tower is used to make round and uniform high-quality powder. Through large tonnage cold isostatic press compacted, and finally sintered at a high temperature, and then polished, finely processed, and strictly inspected before leaving the factory. Each process is strictly controlled to ensure reliable quality.
