I. Overview of kneading machine: Vacuum kneading machine is a kind of equipment for mixing, kneading, crushing, dispersing and polymerizing high-viscosity and ultra-high viscosity elastoplastic materials into chemical products. It has full functions, varieties and applications. It is especially suitable for various industries such as plastics, rubber, silicone rubber, dyes, pigments, inks, food bases, pharmaceuticals, architectural coatings, carbon, and fiber.
Second, the characteristics of the kneading machine:
1. In addition to the extra large kneading machine, the general machine adopts a through-disc for easy installation.
2. In the transmission system, the small kneading machine (1-100 liters) adopts the worm wheel or cycloidal pinwheel reducer, and the large kneading machine (100-2000 liters) adopts the hard tooth surface reducer, which makes the transmission with the main machine stable and small. ,long life.
3. The mixing paddle and the inner wall of the mixing tank which are in contact with the material are made of stainless steel to ensure the purity and quality of the product.
4. The shaft seal structure is advanced and the sealing effect is good. The high required shaft seal adopts our special vacuum box shaft seal structure to ensure that black material will not be ground.
5. Centralized electrical control (including main engine operation, hydraulic reversing, hydraulic opening and constant temperature control) and accurate temperature control and temperature display for easy operation and process control.
Third, the classification of kneading machine:
1. According to the size of the product, the capacity of the kneading machine has been serialized from 1 liter to 6000 liter.
2. According to different purposes, the kneading machine can be made into normal pressure, vacuum and pressure type.
3, according to different heat transfer media, divided into steam heating, heat transfer oil electric heating and water cooling type.
4, according to different discharge methods, divided into hydraulic tilting cylinder discharge, ball valve discharge and screw extrusion type.
5. According to the weight and impact of the load, it is divided into standard type and heavy type.
6. According to the characteristics of the material or the nature of the liquid material added in the kneading, it is divided into ordinary type, increased safety type and explosion-proof type.
7. According to the classification of the stirring paddle speed, it can be divided into single speed type, double speed type and speed regulation type.
Fourth, the scope of application: vacuum kneading machine is widely used in high viscosity sealant, silicone rubber, neutral acid glass glue, chewing gum, bubble gum, pulp, cellulose, also used in batteries, inks, pigments, dyes, pharmaceuticals, resins, plastics , rubber, cosmetics and other industries.
Five, common forms
The kneading machine can be made into four types: ordinary type, pressure type, vacuum type and high temperature type. According to the material, it can be divided into carbon steel kneading machine, stainless steel kneading machine and special material kneading machine. The temperature adjustment mode adopts a jacket, steam, oil heating, water cooling and the like, and uses a hydraulic tumbling cylinder and a cover. The discharging method includes hydraulic pressure, overturning of the cylinder, ball valve discharge, screw extrusion, hydraulic flap discharge and the like. The temperature, time, viscosity and other related data in production can be controlled and recorded in real time through PLC. The cylinder and the contact between the blade and the material are made of stainless steel, alloy steel, manganese steel and other materials to ensure product quality.
