Cement tank is usually used as a supporting product of concrete mixing plant (building), and it is widely used. But Xiaobian still wants to remind you that when you buy cement tanks, you should carefully check whether the hopper structure is reasonable. Because the hopper structure is important to the performance of cement tank. The reasonable shape of hopper structure, the shape and position of hopper and discharge port are of decisive significance to prevent arching of cement tank and promote the overall flow. The shape of the hopper structure and the position and shape of the discharge port determine the ability of the material to pass through the hopper, while the mechanical properties of the material restrict the structure, shape and size of the hopper itself.
           

混凝土搅拌车料斗的卸料口位置通常有中心卸料、边角和侧边卸料，后二者由于存在不对称性，成拱的可能性小，但在相同的倾角下要求料斗的高度大一些。料斗的倒锥通常是从圆形到圆形，方形到方形，圆形到矩形，或矩形到圆形，倒锥下口的形状，常受配料器入口形状的制约，使两者配合起来，便于卸料而不结拱。

The position of discharge port of concrete mixer hopper usually includes center discharge, corner discharge and side discharge. The latter two are not likely to form arch due to asymmetry, but the height of hopper is required to be larger under the same inclination angle. The inverted cone of hopper is usually from round to round, from square to square, from round to rectangular, or from rectangular to round. The shape of the lower opening of the inverted cone is often restricted by the shape of the inlet of the batcher, so that the two can be combined to facilitate discharging without arching.

为了获得畅通的整体流动，避免结拱，水泥罐有各种形式的料斗可供选择。对称料斗的对称两边的物料向中间挤压，易阻塞结拱，但容易制作；相对于非对称料斗，其长度较小，多用于流动性好的物料，非对称料斗与前者的情况相反，不易结拱，故采用较多.但同样倾角，其料斗长度比对称者要长。

In order to obtain smooth overall flow and avoid arching, various types of hoppers are available for cement tank. The material on both sides of the symmetrical hopper is squeezed to the middle, which is easy to block and arch, but it is easy to make. Compared with the asymmetric hopper, its length is smaller, and it is mostly used for materials with good fluidity. The asymmetric hopper is opposite to the former, which is not easy to arch, so it is used more. But with the same inclination angle, its hopper length is longer than that of the symmetric hopper.
