Zircon sand, as a multifunctional material with broad application prospects, is increasingly used in ceramics, aviation, aerospace, automobiles, machinery and other fields. Henan Zhengzhou Mining Machinery Co., Ltd., as a manufacturer focusing on grinding equipment production and process design, has recently successfully designed and provided a complete zircon sand grinding production line solution for a customer in West Asia, demonstrating the company's technical strength and service level in this field.

The core of the project is to finely process the 75μm zircon sand raw material to less than 45μm to meet the needs of high-end applications. The design of the production line fully considers the characteristics of zircon sand and its requirements in subsequent applications, ensuring the high purity and quality of the product.

The specific process is as follows:

l  Raw material preparation:

75μm zircon sand raw materials are first unloaded into the raw material bin through ton bags, and then sent to the ceramic ball mill by a screw conveyor.

l  Grinding process:

The ceramic ball mill finely grinds the zircon sand to reduce its particle size to below 45μm. This link is the key to the entire production line and directly determines the quality of the final product.

l  Grading and screening:

The ground material is sent to the powder selector through a bucket elevator for fine particle size classification. Fine powder less than 45μm is collected in the fine powder buffer bin, while coarse powder greater than 45μm is returned to the ball mill through a screw conveyor for re-grinding to ensure that all materials reach the specified particle size.

l  Pneumatic conveying:

Fine powder is transported to the finished product bin by high-speed air through the cooperation of a pneumatic screw conveying pump and a Roots blower, achieving effective and clean material transfer.

l  Dust removal and environmental protection:

To ensure the cleanliness of the working environment and the health of operators, dust removal points are set up at key locations of the production line, such as the top of the raw material warehouse and the outlet of the ball mill. The gas after dust removal is discharged out of the factory by the induced draft fan. At the same time, a top dust collector is installed on the top of the finished product warehouse to ensure pressure balance in the warehouse and reduce dust.

l  Equipment anti-corrosion:

Considering the sensitivity of zircon sand to iron, the equipment in direct contact with the material in the production line is treated with stainless steel or ceramic patches, which effectively controls the iron content and ensures the purity of the zircon sand.                                      

Henan Zhengzhou Mining Machinery Co., Ltd. not only provides high-quality grinding equipment, but also has comprehensive process design capabilities, and can tailor-make a full range of services for customers, including project feasibility studies, process flow design, equipment layout planning, equipment manufacturing, installation and commissioning, and after-sales training. The successful case of the zircon sand grinding production line once again proves the capabilities and market competitiveness of Zhengzhou Mining Machinery in the field of grinding equipment.

In short, the construction and operation of the zircon sand grinding production line not only demonstrates Zhengzhou Mining Machinery's profound foundation in technological innovation and process optimization, but also opens up a broader space for the application of zircon sand in various industries, and promotes the technological progress and sustainable development of related industries.
