Machine-made sand screening project in cooperation with Liming Heavy Industry

Liming Heavy Industry is a well-known brand in my country's machinery manufacturing industry. The brand is affiliated to Henan Liming Heavy Industry Technology Co., Ltd. Liming Heavy Industry Technology is a joint-stock enterprise that mainly produces large and medium-sized series of crushers, sand making machines, and grinding mills, integrating R&D, production, and sales. The company is headquartered in the Zhengzhou National High-tech Industrial Development Zone, covering an area of approximately 150,000 square meters. It has several wholly-owned subsidiaries. The machinery and equipment manufacturing and production base located in Shangjie covers an area of 70,000 square meters. In 2010, sales exceeded 1 billion yuan, of which export earnings reached 370 million yuan. In 2011, sales reached 1.35 billion yuan, achieving new breakthroughs. Since its establishment in 1987, the company has adhered to the scientific management methods of modern enterprises, precision manufacturing, continuous innovation, and has rapidly developed and grown into a shining pearl in my country's machinery manufacturing industry.

Natural sand resources have a certain limit, and long-term large-scale mining will affect the natural environment. Coupled with the continuous development of my country's economic construction, natural sand can no longer meet the diversified requirements for construction sand, and machine-made sand has emerged. The circular vibrating screen used in the sand making line is mostly used in stone lines. For machine-made sand finer than 4.75mm, the screening accuracy is too poor and cannot meet the usage standards.
