--Introduction
SD220 machine is the fourth generation product of our factory which is designed after our technicians combine kinds of brick machines' merits through many years' production experience. It is the best one of the small type brick machine for the synthetic economic benefit at present. It is welded with profiled bar and all of its gears are made of 45# steel and alloy steel and through processing of Lathe for gear and quencher and cementite quencher, then put into gear boxes. The running part of the machine is driven by bearing running and has airproof equipment for mud and water seal. The machine has the features of handsome shape, reasonable structure, good performance, high quality, smallness, lightness, high efficiency, durability, and convenience, and the user can use it everywhere and do not need a special place. The machine can be widely used and it is fit for clay, black earthly, mixed earth and so on. The machine is the best choice of brick equipment for small factories and professional individuals.

--Structure and Working Theory
The whole machine is composed of Mud-mixer, Bar-cutter, Brick-cutting Lathe. The power enters from the head of the axis after the flat pulley and gears slow their speed. The earth with moderate humidity will be put into the hopper from the upper part of Mud-mixer, and fall into the Mud vat after it is crushed down, then it is puddled by Screw in the vat and put forwards. At last it is squeezed into standard mud bar from the entrance. Under the drive of the Screw, the mud bar enters into Bar-cutter and goes ahead on its board. When it comes to the proper place, the pull pole of the Bar-cutter is pulled to cut mud bar. When the cut mud bar comes to the right place of the brick-cutter, the control pole of the brick-cutter is held down to make the mud bar move on the slab; So the mud bar is cut into standard brick, and then come to Brick-receiver.
