Σ Paddle Kneader: Z Series
The kneader is a wet grinding equipment with a pair of mating and rotating blades (usually Z-shaped), under the action of shear force caused by different speeds, the materials can react quickly and finally get uniform mixing.
The kneader can be used for kneading and mixing rubber and vulcanized rubber of various high-viscosity and elastic-plastic materials. Many factories or laboratories are inseparable from it in the production and manufacture of silica gel, sealant, hot melt, food gum base, and pharmaceutical traditional Chinese medicine preparations.
The kneader is a unique mixing and stirring equipment. Generally, there are two Σ paddles, and the parallel intersecting differential type arrangement is used, which can make one paddle faster and the other paddle faster. Slower, resulting in high shear forces. Different paddle speeds allow the materials to be kneaded to be cut quickly so that the materials can be mixed in an optimal state.
The main structure of the Z-blade mixer
The whole part is mainly composed of six parts including the kneading part, base part, hydraulic system, transmission system, vacuum system, and electric control system. The part of the Z blade mixer is composed of a cylinder block, pulp shaft, wall panel, cylinder head, and so on. The hydraulic system is controlled by two small oil cylinders and two large oil cylinders by a hydraulic station. This hydraulic system can well meet the functions of opening and closing the large cover and turning the mixing cylinder. The system design pressure is 7.0Mpa and the electric control The system has manual and automatic electronic control systems, which can be selected and requested by the user at will, and the operation is convenient and reliable.
Characteristics of Z Blade Mixer
The Z-blade mixer mainly uses two Z-shaped paddles with different speeds to produce intense shearing, extrusion and stirring, so that thin materials can be mixed at high speed to produce uniform materials. Z blade mixer can be made into ordinary type, pressure type, vacuum type, etc. The main design method is determined according to the needs of users. FRANLI‘s engineers adopt heat transfer oil heating, steam, water cooling, etc. according to the user’s usage habits and temperature adjustment methods. The discharge method is hydraulic tilting, bottom ball valve discharge, screw extrusion, etc., to meet the needs of users in an all-around way.
The Z blade mixer can be designed in a heating or non-heating mode according to the needs. The heat exchange methods usually include electric heating, steam heating, circulating hot oil heating, circulating water cooling, etc. The discharge methods of the Z blade mixer include hydraulic cylinder dumping, ball valve discharge, screw extrusion, etc. The cylinder body and paddles in contact with the material are made of SUS304 stainless steel to ensure the quality of the material.

How to use the Z-blade mixer
In general, when using the equipment, the user needs to clean the kneading chamber of the Z blade mixer, and after turning on the equipment, it needs to be idling for 10-15 minutes. This step is mainly to ensure that the machine is clean before use. There is no problem. After ensuring that the equipment is in good condition, the user can use it for production mixing. There are certain differences between the new machine and the old machine in terms of gears and deceleration motors. The main reason is the noise problem during use. Generally, the new machine is very noisy when it is in use. Therefore, the new machine needs a period of running-in. After a natural running-in, the noise will stop abruptly.
The vacuuming, stirring, and mixing processes of the Z blade mixer produced by FRANLI have been recognized by many partners, depending on the professionalism of the manufacturer. We mainly use steam heating or water cooling to make the material go through the whole process of kneading to ensure uniform cooling and heating. It has the characteristics of fast temperature adjustment, not easy to burn, and fast freezing speed. The equipment has a variety of discharge methods, among which the hydraulic flip discharge is the most used. Before the Z blade mixer is discharged, the empty valve needs to be released, and the whole discharge process is fast and uniform.
The cover on the top of the device is mainly made of silicone rubber, while the shaft end is in the form of a mechanical seal. This sealing method can bring good sealing performance. The user also needs to check whether other firmware is loose, whether the steam pipe is leaking, Whether the circuit is leaking, etc. For the electric heating type Z blade mixer, it is also necessary to have a grounding device to prevent irreversible consequences during the use of the machine.
