    Main Features

    The molded product has high compressive strength, good density, good frost resistance and accurate size. The four guide columns are plated with chromium and have good torsional strength and wear resistance. The separator adopts the sensor and hydraulic proportional drive technology, and produces the forced centrifugal discharge under the action of the swing arm and the arc breaking mechanism, so that the separation is rapid and uniform, and the production efficiency is improved. Mold and indenter positioning is more accurate, the use of low mold orientation vertical, directional vibration and upper mold pressure vibration, and the production of blocks uniform density, high strength, greatly improve the efficiency of production. This machine has good performance, high efficiency and low energy consumption, and conforms to JC/T920-2003 standard. It has achieved good economic and social benefits since it was put into the market, and is an ideal equipment for producing high-quality blocks and concrete bricks.

    This model has the following features:
