Brief Description:Laboratory twin-screw granulation equipment can broadly be categorized into two types. One type is the shaping and processing method, which mainly involves processing powdered materials through specific equipment and methods to form agglomerated materials that meet specific requirements for shape, size, composition, density, etc. This method pays particular attention to controlling the properties of individual agglomerates.
Laboratory twin-screw granulation equipmentBroadly speaking, any process that aggregates small particles into larger entities and any process that divides "large" blocks into smaller particles can be referred to as a granulation process. The former is called powder granulation, and the latter can be referred to as crushing granulation. Among these, twin-screw granulation technology can broadly be divided into two categories. One category is the shaping and processing method, which mainly involves processing powdered materials through specific equipment and methods to meet certain requirements for shape, size, composition, density, etc., of the agglomerated material. This method particularly focuses on controlling the properties of individual agglomerates. The other category is particle size enlargement, which mainly involves aggregating fine powders into coarser particles. This method focuses on controlling the properties of the entire batch of material.
The forming process is widely used in current industrial applications, but the process system is relatively complex, and the production capacity is relatively low, with higher production costs. In contrast, increasing the particle size is mostly applied in processes where the requirements for particle shape and density are not high. Such systems are simple and easy to operate, typically offering larger production capacities and lower production and operating costs.
Below is an introduction for youLaboratory twin-screw granulation equipmentPrinciple of operation:
After the new gear transmission box has been "run-in", the oil should be replaced, and then the oil should be changed every 4000 hours of operation. Regularly clean the oil filter and remove sediment at the bottom of the oil tank, and regularly lubricate the lubrication points. Check the temperature rise of the motor and the oil tank, whether the bearings are locally overheated, any abnormal noise from the motor and gears, oil leakage, the radial runout of the spline shaft, and the contact clearance between the spline shaft and the screw end face. Conduct daily maintenance on the transmission system.
Some screw homogenization sections are a completely smooth rod known as the head, but there are also those with grooves or milled patterns. The head serves to stir and regulate the material, eliminating pulsation (pulsing phenomena) during flow, and it increases the material pressure, reduces the layer thickness, improves heating conditions, and can further enhance the screw's plasticizing efficiency.
Countercurrent — the flow direction is opposite to the main flow, caused by the pressure gradient due to resistance from the die, multi-hole plate, filter plate, etc. Cross flow — the melt flows in a direction perpendicular to the screw thread wall, affecting the mixing and heat exchange of the melt during the extrusion process. Leakage flow — the backflow formed at the gap between the screw and barrel due to the pressure gradient, flowing along the axial direction of the screw.
