The present invention relates to a transfer screw for crusher is mainly used for food grinder. The subject innovation is in the grinder feed screw for transferring the material to be added such as vegetables, fruit and other grains, pressure-fed (押送) means for radially continuous form is pushed while feeding the injected material along its direction of rotation to one direction of the screw wing and characterized in that hayeoseo it includes. The subject innovation is to enhance the pressure-feeding force of the material by increasing the friction coefficient of the material to be added is made effective pressure-feeding of the material. Thus, the subject innovation can be prevented enable effective transfer of the material injected in, and can shorten the length of the screw, the low-speed rotation, and inputs this to the hopper out external scattering. In addition, the subject innovation is President and also primary crushing effect can be obtained because the particles or the liquid phase to be obtained the material to reduce the grinding load of the main crushing means put in a short time. Thus, the present design may not have to be enlarged or rotated with high speed the length of the screw more than necessary due to the increased pressure-feeding force to reduce power consumption and thus, can extend the life of the machine. Conveying screw, pressure-feeding means.
