QTJ4－20 Hydraulic Automatic Baking-Free Brick Machine is an equipment involving mechanical, hydraulic and electrical control systems. It is characterized by high efficiency, reasonable design, compact structure, easy operating and convenient maintenance.

For the product forming, the machine takes the hydraulic force as the main and the mechanical force as the auxiliary, through vibrating and pressing, to finish the forming procedure. The formed products are high in compressive strength, good in density, perfect in anti-frost and precise in dimensions. Its four guiding columns are coated with cadmium, having perfect torsional strength and wearing capacity. Its material distributor, using sensor and hydraulic proportional driving technologies, can produce forced centrifugal discharging under the function of swing and arc-breaking mechanism to provide quick and even material distributing, and to increase the productivity.
