Plastic grinding machine? Plastic grinding machine is widely used in the grinding and processing of various plastic materials in the fields of chemical industry, waste recycling, plastic pipe profile manufacturing, plastic modification and other fields. Changyuan Machinery is classified according to the grinding principle. The grinding mills are mainly divided into two categories: rotor (turbine type) grinding mill and disc grinding mill. According to the grinding method, they are divided into normal temperature grinding grinding mill and cryogenic grinding grinding mill. Usually we The most common one is a normal temperature grinding mill. The rotor mill was formed in the early 1980s. It has been continuously used, improved and updated, and is still in use today. The model has evolved from the original SMP-400 model to the current SMP-500, SMP-600, and SMP-800 in 2004. Major improvements have been made in the structure. The output of Changyuan Machinery's plastic grinding mill has also increased from the initial tens of kilograms to hundreds of kilograms and even nearly 1 ton per hour. At the same time, the fineness has also developed from the previous fixed number to the current adjustable . The disc grinding mill was manufactured at the end of the last century. The grinding principle of Changyuan Machinery plastic grinding mill is similar to the traditional mill grinding principle in ancient my country. It is used in the field of plastic grinding and has the characteristics of low energy consumption and high output. , the grinding materials are PVC, PE, PC, PA, ABS and other materials that do not contain calcium powder, and can also be used for rubber, plant fiber and other materials. The product models and specifications vary depending on the manufacturer. The main models are MF-250, MF -350?, MF-450, ?MF-550?, MF-800, etc. Changyuan Machinery's grinding disc structure design has evolved from an early two-ring toothed disc to a single-ringed toothed disc, and then to a double-sided toothed disc, gradually improving wear resistance and increasing output. ●The plastic grinding machine adopts a new tool structure, which increases the output and overcomes the characteristics of low output and coarse powder of PE grinding. ●The plastic grinding machine has high output, fine grinding, energy saving and environmental protection. ●The scope of application of the plastic grinding machine It is widely used and can grind PVC, PE, PS, PA, PC and other plastics. ●The plastic grinding mill is easy to install and maintain. You can clean it by opening the door cover. ●The entire plastic grinding process of the plastic grinding mill is fully sealed and there is no dust pollution. ● The powder size of the plastic grinding mill is adjustable from 10 to 120 meshes and is easy to adjust. ●Plastic grinding machine The plastic grinding machine cooling system uses a combination of wind and water for cooling. ●Plastic grinding machine has high-quality wear-resistant steel cutting tools with high output. Good wear resistance. ●The plastic grinding mill operates fully automatically and continuously. ? ●The plastic grinding mill has a compact structure and a small footprint. ? ●The plastic grinding mill has an integrated steel structure, making it stable and reliable. ? ●The closed design of the plastic grinding mill uses its own air volume and pressure to collect the prepared powder without dust leakage. ? ●Plastic grinding machine's user-friendly knife adjustment, design concept, and fixed knife gap adjustment only takes a moment, easily. ? ●The plastic grinding mill is easy to maintain and clean. ? ●Plastic grinding machine This machine can grind various soft and hard leathers into fibrous shapes at room temperature: artificial leather, PVC, PE and other materials with different molecular structures can be ground into 20-80 mesh powder, which is especially suitable for plastic modification. ? MF-400 grinding mill is a special equipment for processing and grinding thermoplastic plastics in plastic products factories. The powder ground by this machine using scrap scrap recovered during the production process should account for 20-30% in the processing formula. The chemical and physical properties of its products all meet the standards. The use of this machine requires low investment and quick results. It is a good helper for plastic product factories to reduce costs and save money and solve the problem of accumulation of waste and defective products.
Overview of SMW-500 Plastic Mill
This machine is the latest mill independently developed by our factory. Its features are as follows:
1. Compared with grinding mills of the same type, the output is greatly improved (increased output by 20%-50%) under the same power consumption, saving energy consumption.
2. A dust collection device is added to effectively reduce dust pollution.
3. Turning off the fan to discharge material reduces the labor intensity of operators.
4. The door cover of the main machine can be opened for easy maintenance and tool replacement.
5. The use of Feng Shui double cooling can better reduce the working temperature in the machine body, and the ground materials are not easy to degenerate. It is also conducive to the grinding of heat-sensitive plastics, and can grind some PE and ABS. system.
Working principle
1. The working part of this machine is the cutterhead.
The high-speed particles are partially crushed after impacting the tooth plate and the tooth plate, and are extracted by suction, while the larger particles continue to impact, crush and are extracted. This reduces the load on the cutterhead, improves grinding efficiency, and allows the powder to be cooled evenly.
2. Low temperature is the main advantage of this machine. In terms of heat work equivalent: work done per hour is replaced by 860 kcal of heat. This machine uses external ventilation with an air volume of 50m3/kw. Most of the heat is taken away by the temperature difference between the inlet and outlet air. A small amount of heat is solved by water cooling. Requirements: The inlet temperature of the cooling water should not be greater than 25°C, and the outlet water temperature should not be greater than 45°C. In summer, the cooling water flow should be increased appropriately to reduce the temperature.
Usage: Our factory absorbs advanced foreign technology to develop a series of grinding machines, which are used for successfully grinding PVC plastics, high-density PE, or other plastics with low to medium hardness. It has been proved by the practical operation of a professional factory for plastic products that if 20%---30% calcium carbonate is added to the ground powder during processing, the chemical and physical properties of the products will remain unchanged as the indicators of new materials, and the output can reach 150~ 220KG (40-80 mesh). Therefore, this equipment is the best equipment for plastic product factories to reduce costs and eliminate waste accumulation.
