I suggest you check the dry granulator with a few questions below.
1 material characteristics, refers to the material's compressibility, fluidity (sugar viscosity), heat sensitivity and the material's own humidity, water content and so on. It is necessary to conduct tests before dry granulation of the material to fully understand the characteristics of the material.
2 The rotation speed of the pressure roller and the rotation speed of the pressure roller determine the residence time of the material in the rolling zone between the pressure rollers, which directly affects the discharge of air contained in the material.
3 The gap of the pressure roller refers to the close distance between the two pressure rollers. This data is closely related to the pressure of the material between the pressure rollers and the amount of material passing through it. At the same time, the gap of the pressure roller can be adjusted, and the material rolling can also be changed. At the same time, the rolling angle of the product is generally easy to roll and shrink, and the corresponding rolling angle is large (that is, the gap of the pressure wheel can be adjusted smaller).
4 feeding system and screw feeding pressure, different material characteristics, the required pre-rolling pressure is not equal. Therefore, the feeding speed and the screw feeding are reasonably adjusted, and the material is more stable through the pressure adjustment, and the dry rolling effect can be effectively improved.
5 The side gap and sealing of the cylinder seat and the pressure wheel can enable the Zui to reduce the side gap leakage powder to a low degree, so as to improve the product yield.
6 Water cooling on the surface of the pressure roller, in order to more effectively reduce the extrusion heat generated by the material during the rolling process, the surface of the pressure roller is forced to be cooled by water, and the ice water machine with water circulation cooling system can be pressed according to the needs of the user. The surface temperature of the wheel is adjusted to below normal temperature to enable more effective cooling of the surface of the pressure roller and improve the dry rolling effect.
In addition, it is necessary to inspect the parts: (1) The material of the pressure roller: customized by special materials, and subjected to high temperature quenching and tempering treatment, so that the pressure roller has good plasticity, toughness and strength, and improves the comprehensive mechanical properties; The surface of the pressure roller: on the surface of the pressure roller, it should generate a large friction force with the material, which can produce a large adhesion between the materials, which is beneficial to improve the rolling effect, and the ideal molded product is obtained. Therefore, it is necessary to select different pressure roller surfaces according to different materials; (3) Hardness treatment on the surface of the pressure roller: adopt international advanced surface hard nitriding treatment technology to ensure surface hardness of HV1200o or more and nitride layer depth of 0.2mm. The pressure roller has strong wear resistance, improves the fatigue resistance, and has better corrosion resistance. The service life of the pressure roller is guaranteed for 5 to 12 years under normal use; (4) The structure of the pressure roller: unique, A reasonable internal structure allows the surface of the pressure roller to be well cooled. (5) The material of the pressure roller is made of stainless steel 304-2B.
