Double rotor sand maker professional solution for lower costs and higher efficiency in concrete plant sand making

Double rotor sand making machine that eliminates secondary crushing Double Rotor Sand Crusher Equipment Overview The double-rotor sand making machine uses a "rock-on-rock" crushing principle with two rotors, enabling simultaneous production of aggregates and manufactured sand in a single pass – finished products are produced immediately without the need for repeated crushing. The machine has a processing capacity of 20–280 t/h and a maximum feed size of ≤30 mm. It is suitable for crushing and sand making from medium‑hard materials such as limestone and bluestone. Key advantages include a high reduction ratio, well‑rounded finished particles, continuous gradation, and adjustable fineness modulus – fully meeting the high standards of ready‑mix concrete plants for sand and aggregates. The dual feed inlets combined with a hydraulic opening cover make maintenance convenient, reduce wear part consumption, extend machine life, and keep the failure rate at ≤0.5% per 1,000 hours – far below…
