Methods and devices for agitating material. In some embodiments, an agitator is positioned in a receptacle to agitate material therein. The agitator may include a shaft, an arm extending from the shaft, and at least one knife extending from the arm. In some embodiments, the agitator may further include one or more agitator elements operably connected to at least one knife.

A combined crushing granulation drier has a combined tank, which is provided with a plurality of layers or a single layer. Two adjacent layers of tank bodies of the combined tank are connected by granulator connecting flanges. The granulator connecting flanges are arranged on the inner side of the combined tank. The ends of the flanges are fixed by bolts to form a fast-assembly type structure. A feed temporary storage bin is arranged at the upper part of the combined tank. The feed temporary storage bin and the tank body at the uppermost layer of the combined tank are connected, fixed and sealed by connecting flanges of the feed temporary storage bin. The combined tank is internally provided with a rolling unit. Each layer of rolling drum is internally provided with a rotating speed sensor.

The present invention is a vertical drier which dries the asphalt road upper structural members like aggregate and like asphalt coating which is desired to be recycled (RAP) and which takes the humidity of said asphalt road upper structural members; and which has a vertical body having an end through which said members are discharged and having another end which is opened to an accumulation compartment; and where the hot air, heated by a heat source, is transferred inside said body. Said drier is characterized by comprising at least one drying box which has a chamber form where the poured members are accumulated in the inner part thereof and which extends orthogonally to the flow direction inside the body; in order to keep the members, which pour inside said body from an inlet part, for certain duration and in order to transfer said members from the outlet part to the accumulation compartment step by step.
