The high-efficiency wet granulation machine is designed around the entire process of "material mixing - pulp spraying - particle forming - discharge and discharge". The core structure is divided into seven modules, which work together to ensure granulation efficiency and particle quality, as follows:
1、 Host rack and casing
The frame is welded with high-strength steel and treated with rust prevention to stably support internal components and avoid vibration displacement. The shell is designed with stainless steel enclosure, which meets hygiene requirements and prevents dust overflow and material pollution; An openable observation door is installed on the side for easy viewing of granulation status and subsequent cleaning and maintenance.
2、 Mixing and Mixing System
The core consists of a stirring motor, a stirring shaft, and a stirring blade. The motor drives the shaft to rotate through a reduction mechanism, and the blades are divided into "plow blade type" and "screw belt type" (suitable for viscous materials, anti caking). Some models are equipped with auxiliary mixing blades to improve uniformity.
3、 Granulation cutting system
Including cutting motor, cutting shaft, and cutting blade, the motor speed can be adjusted according to the particle size. Cutting knives are mostly multi bladed, with precise grinding of the blade edge, which can quickly cut wet material into regular particles without drawing; Some of the cutting tools are detachable and easy to adjust or replace.
4、 Liquid jet pulping system
Including adhesive storage tanks, metering pumps, spray pipelines, and atomizing nozzles. The storage tank is filled with adhesive, and the bottom is equipped with agitation to prevent sedimentation; The metering pump accurately controls the quantity (error ≤ 2%), and the atomizing nozzle turns the adhesive into small droplets, evenly covering the dry powder to avoid local high humidity sticking to the wall.
5、 Transmission and speed control system
Composed of a motor, reducer, pulley, and frequency converter. Motor selects power according to load; Reduce speed and increase torque of the reducer to prevent material splashing or mixing stagnation; The frequency converter achieves stepless speed regulation and can be adapted to the process by setting parameters through the panel.
6、 Discharge and Unloading System
Including discharge door, cylinder and discharge device. The discharge door is located at the bottom and is controlled by a cylinder switch. After granulation, the door is opened and discharged by gravity; Some models are equipped with spiral unloaders to transport particles to subsequent processes to prevent blockage. Sealing strips are installed at the contact between the door and equipment to prevent leakage.
7、 Control system
Composed of a control panel, PLC controller, and sensors. The panel is equipped with a touch screen and physical keys, which can set parameters (speed, spray volume, etc.) and view the operating status; PLC receives sensor signals and automatically adjusts parameters to ensure stable operation. It also has fault alarm and shutdown functions.
