SBM Rotor Makes New Concept of Sand Making

Since the reform and opening up, China has not only become a “world factory” but has printed “Made in China” products in every corner of the world. At the same time, China has also become a “world site.” Small demolition and construction have transformed China's face. The construction requires a large amount of raw materials for sand and gravel, while the limited natural sand and gravel has greatly hindered the construction of our country. At this time, VSI sand making machine came into being. The machined sand not only has no limitation on the quantity of natural sand, but is also more stable in quality than natural sand, and its cementing strength with cement mortar is also higher.

A sand producer with reliable quality and excellent performance is very important for construction projects. The rotor as the core component of the sand making machine, its structural design is directly related to the performance and service life of the whole machine. Shanghai SBM Machinery Co., Ltd. has continuously improved and optimized its rotor design and manufacture, and developed a new deep cavity rotor.

Compared with conventional sand machine rotors, the launch depth of new deep cavity rotors is about 50% higher than that of ordinary rotors, which means that there is more space between the material cone, the impeller guard ring, and the upper and lower runner plates. The increase of the internal space enables the rotor to accommodate more feeds and the amount of processing is greatly increased. At the same time, the increase of the internal space can also reduce the wear of the material on the upper and lower runner plates and extend the service life of the runner plates.

We have also made many improvements in the other core components of the rotor. For example, the impact block is changed from the traditional rectangle to a new diamond design, which avoids excessive wear of the contact material in the rectangular impact block during use, thereby effectively increasing the service life of the impact block; The material head is designed in a segmented manner and the auxiliary throwing head design is successfully applied. In this way, the utilization efficiency of the throwing head can be increased by more than 50%, which effectively avoids the accidental replacement of the throwing head caused by material negligence and the material damage to the impeller body in the actual operation, and greatly improves the safety factor of the machine.

Innovation is not necessarily a major invention that changes the world. In this era of extremely rich material resources, perhaps focus on the details, focus on the user's real needs and experience, and thus quickly attack, made a series of "micro-innovation", but also can make the machine's performance has been effectively upgraded. This is also one aspect of the SBM R&D team. Little rotor, out of the new concept of sand making.
