Zoomlion's new generation of sand making machine in Ningxiang Industrial Park off the assembly line

Sand making machine is also called vertical shaft impact crusher. Its principle is to break through the anvil iron or stone layer in the surrounding circle by high speed rotating impeller to produce qualified construction sand. The technical difficulty lies in the need to have efficient crushing capacity, but also to be able to break out the round particles of qualified, uniform-quality construction of sand. Zoomlion's new generation of products successfully meets these two requirements.

Closed recycling system makes the site clean and tidy

In terms of technological innovation, Zoomlion adopted a discrete element method to perform basic technology research on the new generation of sand making machines. It used collision energy and number of collisions as evaluation indicators to study the crushing effect, and combined it with experimental data for simulation analysis and verification. The technicians analyzed the sand formation rate and grinding rate with different types and sizes of anvil irons, and developed an industry-first crushing method. The new generation of sand-making machine is equipped with the industry's first "iron-stone sequence mixed-hit" crushing method to ensure the sand-forming rate while ensuring the sand-forming granularity (voidage). This crushing method was tested at Hanshou early this year. In the validation process of the sand making machine system, under the condition of 60 tons of qualified sand production capacity, the sand forming rate of the initial generation product has increased significantly. The crushing method and several other technologies have applied for invention patents.

In terms of cost, Zoomlion's new generation of sand making machine adopts a modular design and can be equipped with a variety of crushing techniques such as stone paving stone, stone paving iron and stone iron, and can be matched with the material feeding chamber with flow control function. The power system with different powers and the transmission system with different rotation speeds can be selected to meet the various crushing needs of various types of stone and meet the needs of different construction sites. The combination of different modules can realize different functions such as sand shaping machine, high-speed grading machine, and grain size adjustment machine. At the same time, through the optimization of product structure, the number of wearing parts is reduced by 13.5% compared to the initial generation products. The daily maintenance and routine maintenance of the product can open the sand feeder inlet chamber, observation door and other components without using a wrench or other tools.

The new generation of ZXS1000H-400 plastic sand making machine is Zoomlion’s new product developed and developed on the basis of absorbing the advanced experience and technology of the mining crushing machinery industry, marking that Zoomlion’s heavy machinery sand product has reached a Higher steps.
