Building materials, metallurgy and other industries are large energy consumers, and the supporting power of ball mills widely used in them is relatively large. The particle size of materials entering the ball mill is an important factor that directly affects the output and energy-saving efficiency of the ball mill. In recent years, the industry has promoted the "more crushing and less grinding" process to reduce energy consumption by reducing the particle size of the materials entering the grinding process. At present, the existing jaw crushers, hammer crushers, cone crushers, and roller crushers, roller presses and other crushing equipment introduced in the market in recent years are difficult to achieve a material size of 60% less than 2mm, which is common. Disadvantages of high energy consumption, high noise and large output granularity.

Most of the existing double-rotor crushers are driven by two sets of motors. Due to the installation and use of multiple sets of equipment, there are major problems in installation space, use cost and transmission synchronization control. The utility model drives a coaxial double-output speed reducer by a set of electric motors, which can effectively reduce space, reduce cost, improve transmission performance, and realize the function of single input and multiple outputs. In addition, the vertical double-rotor crusher realizes full-disc compound crushing, and the output particle size reaches more than 90% of the material ≤ 0.2mm.
