With the increasing global resource tension and the growing prominence of environmental issues, the reuse and resource utilization of waste materials have become important topics in social development. As a common by-product of mining and industrial production, the rational reuse of silica waste not only helps alleviate resource pressure but also effectively reduces environmental pollution. The following are some of the main applications of silica waste:
Sintered clay brick production: Waste silica powder can be used in the production of sintered clay bricks. By mixing it with clay and undergoing specific processing techniques, high-quality sintered bricks with high compressive strength, low water absorption rate, and small firing shrinkage deformation can be produced. These bricks have a bright light white color and can be made into colored bricks by adding pigments to meet various architectural requirements.
Silicate cement manufacturing: Silica is one of the important raw materials for manufacturing silicate cement. The high content of silica in waste silica powder can be utilized for this purpose, thereby improving the quality and performance of the cement.
Road paving: Processed silica waste (such as quartz sand) can be mixed with asphalt to pave high-quality roads, enhancing the wear resistance and durability of the road surface.
The LM-Y Vertical Pre-grinding Roller Mill is an advanced grinding equipment developed by SBM based on the LM series vertical grinding mill. It extensively incorporates advanced technologies from both domestic and international sources, and is combined with the company's extensive production experience in crushers and mills. It is an ideal equipment for the powder industry, integrating sand-making and grinding functions.
Equipment Advantages
1.Extensively used, versatile in function: Integrates sand-making and grinding capabilities. Suitable for preparing sand and powder from materials with Mohs hardness below 7, such as limestone, dolomite, calcite, quartz, silica stone, marble, and coal gangue. It can simultaneously produce both sand and powder products, such as 40-140 mesh sand and fine powder above 200 mesh.
2.Intelligent control, adjustable fineness: The entire production line can achieve intelligent control and coordinated production. The fineness of the finished products can be flexibly adjusted according to production needs. Moreover, the proportion of fine powder and fine sand in the product can be flexibly adjusted within a certain range, meeting the market demands of enterprises.
3.High single-machine production capacity and excellent product particle shape: The special grinding curve combined with the laminated crushing principle results in low production energy consumption, high single-machine output, excellent product sand particle shape without sharp corners, and high product value.
4.Low operating cost and easy maintenance: The wear-resistant parts have a long service life. Since the grinding rollers do not directly contact the grinding disc during operation, there is less wear and a longer service life. Moreover, the grinding roller sleeve can be flipped over for use, significantly reducing the cost of wear-prone parts; the grinding part can be lifted out of the machine by a hydraulic device, making maintenance and repair convenient and fast.
5.Easy to operate and reliable in operation: Equipped with a hydraulic system, the grinding pressure can be adjusted conveniently, suitable for materials of various hardness; equipped with a limit device to prevent direct contact between the roller sleeve and the grinding disc liner, avoiding destructive impacts and violent vibrations.
