The company integrates R&D, manufacturing, and installation and commissioning of complete coal washing and preparation equipment. Our products include complete sets of coal washing equipment, coal preparation equipment, jigging machines, coal washing machines, flotation machines, thickeners, dryers, crushers, vibrating screens, and more. We specialize in manufacturing complete sets of coal washing and preparation equipment, jigging machines, coal washing machines, flotation machines, thickeners, dryers, crushers, and vibrating screens. Recognized by the Zaozhuang City Science and Technology Bureau as a "Coal Preparation Equipment Engineering Research Center," the company holds 5 invention patents and over 30 utility model patents. We have undertaken several provincial and municipal science and technology projects, technology transformation projects, and have been awarded multiple national science and technology innovation project certificates. In 2012, the "Xinjia" brand was recognized as a well-known trademark in Shandong Province.
The company's independently developed "modular intelligent coal preparation equipment" project passed provincial scientific and technological appraisal in July 2008 and was listed as a 2009 Shandong Province technology innovation promotion project. This product is an efficient, energy-saving, and environmentally friendly solution for washing and preparing fine coal.
The LTX series modular intelligent coal preparation equipment can wash 1.5 to 4 million tons of raw coal annually. This product features unique design technology and an integrated installation structure, saving approximately 50% of the total investment compared to traditional processes, reducing washing costs by about 60%, increasing fine coal recovery rates by 3-5%, and shortening plant construction periods by 60%. It ensures accurate washing precision, achieves closed-loop water circulation with no environmental pollution, and provides significant economic returns, typically recouping the investment within one year.
In 2007, the company collaborated with the China University of Mining and Technology's Institute of Mining Machinery to develop the DWX type suspended single hydraulic prop product. This product was a key technological achievement promoted during the "Tenth Five-Year Plan" period, holding more than ten national invention and utility model patents. It represents a new generation of coal mine support products directly developed by China University of Mining and Technology!
