This system is a set of automatic bales handling system, to grind the standard bales of rubber into small size granule and homogenize it perfectly, then weigh and transport the granule to the internal mixer. It consists of six parts: introduction conveyor, shredder, granule conveyor, blending drum, anti-sticking preparation device and de-dust device. 　Good mixing uniformity, high weighing accuracy of raw rubber, reduces the impact of human factors, and improves the quality of finished products. 　Higher level automation, easier operation, less manpower. 　Upgraded rubber cutting method, save the need of raw rubber heating, effectively save energy and operation costs. 　Lower discharge temperature, shorten mixing time, improve filling factor, greatly enhance production efficiency.
