GZPK-51/65/83 series high-speed tablet press is a fully automatic high-speed rotary tablet press, which compacts various granular raw materials into pieces twice by a pair of pre-press wheels and a pair of main press wheels.
The general requirements for the granules are as follows：
- If the tablet weight is less than 0.3g, the powder particles screened by 16-20 mesh screens are selected
- If the tablet weight is more than 0.3g, the powder particles sifted by 10-14 mesh screens are selected
- Semi-solid powder, wet powder, fine powder can not be pressed or pressed forming is not good.
The part of the GZPK-51/65/83 series tablet press machine is a fully enclosed tablet press chamber, the material metal in contact with the powder is acid-alkali resistant austenitic stainless steel, and the non-metallic material is non-toxic material. Four transparent Windows can be opened, so that the machine clean without obstruction, easy to replace the punch.
The lower part of the machine is sealed by four stainless steel doors with porous material inside, and contains various driving devices to ensure safety and reduce noise. The process of tablet pressing is completed by five steps: filling, measuring, pre-pressing, main pressing and tablet drawing. The operation of the tablet press is completely controlled by the touch screen on the electric control cabinet.
The main supporting structure of the GZPK-51/65/83 series equipment is a four-column structure. As shown in the following figure, the bottom plate is equipped with a left and right stand, the left and right stand is equipped with a base plate, the base plate and the top plate are supported by four 140×140 columns, the height of the whole machine is only 1981, the center of gravity is low, so the equipment is very stable when running.
The upper main pressure wheel and the prepressure wheel are supported by two support plates, which are directly installed on the top plate, and finally the force is finally transmitted to the top plate and the column to ensure the pressure of the upper main pressure wheel and the prepressure wheel, and reduce the vibration and noise.
