What is PS?
Polystyrene (PS for short) is a polymer synthesized from styrene monomer by free radical addition polymerization, and its chemical formula is (C8H8) N. It is a kind of colorless transparent thermoplastic, with glass conversion temperature higher than 100℃, so it is often used to make a variety of disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes.

PS Features:
Polystyrene has good fluidity, good processing performance, easy coloring and good dimensional stability. It can be processed into various parts by injection molding, extrusion molding, blow molding, foaming, thermal molding, bonding, coating, welding, machining, printing and other methods, especially for injection molding.
A, mechanical properties: high strength, fatigue resistance, dimensional stability, creep is small (there is little change under high temperature conditions);
B, heat aging: enhanced UL temperature index of 120~140℃ (outdoor long-term aging is also very good);
C. Solvent resistance: no stress cracking;
D. Water stability: easy to decompose in water (use with caution in high temperature and high humidity environment);
E, electrical properties: 1, insulation performance: excellent (humidity, high temperature can also maintain the stability of electrical properties, is the ideal material for manufacturing electronic, electrical parts); 2. Dielectric coefficient: 3.0-3.2; 3, arc resistance: 120s
F, molding machinability: ordinary equipment injection or extrusion. Because crystallization speed is fast, fluidity is good, mold temperature is also lower than other engineering plastics requirements. When processing thin-wall parts, it only takes a few seconds and only takes 40-60s for large parts.

PS Application:
PS is widely used in the optical industry, this is because it has good light transmittance caused by it, can make optical glass and optical instruments, can also make transparent or bright colors, such as lampshades, lighting appliances, etc. PS can also be used to produce many electrical components and instruments that work in high-frequency environments. Because PS plastic is a difficult inert surface material, industrial lamination, the need to use professional PS glue bonding.
The use of PS products alone, brittleness, and in PS to add a small number of other substances, such as butadiene can significantly reduce brittleness, improve impact toughness, this plastic called impact PS, its mechanical properties greatly improved, can be used to produce many excellent mechanical parts and components of the plastic.

Description:
PS Polystyrene Plastic Pulverizer Mill Grinder Machine of the PNMF series is available with disc diameter from 300 to 800 mm. These plastic pulverizer machines are high speed, precision grinders for the processing of medium-hard, impact resistant and friable materials. The material to be pulverized is introduced through the center of a vertically fixed grinding disc which is mounted concentrically with an identical high speed rotating disc. Centrifugal force carries the material through the grinding area and the resulting powder is collected with a blower and cyclone system. Depending on the application the machines can be equipped with one-piece grinding discs or grinding segments.
The plastic pulverizer machine is mainly composed of an electric motor, disc-type blade, feeding fan, vibrating sieve, dust removing system, etc.
According to the customer’s needs, you can choose some accessories, such as a converter, vacuum loader, screw loader, magnetic net, metal separator, chiller, pulse dust collector, metering and weighing packaging machine, etc.

Technical Features:
1. The new disc design is of high quality, strong resistance and the life of this grinding disc is double the ordinary ones.
2. The newly designed professional bearings is with a high rotation rate. At the same time using only one drive motor, to ensure the efficient grinding crash, which greatly saves the time of machine operation and engineering control.
3. Easy installation and maintenance, just open the door to clean up.
4. The whole milling process is sealed, without dust leakage.
5. Full automatic design, automatically feeding, discharging and sorting.
6. Grinding gap adjustment is simple, just use the feeler gauge and adjust bolts can be fine-tuning.
7. The mill uses the water and wind double cooling system, Prevent bearing and other parts from overheating.
8. Well-known brand accessories, such as SKF bearings and Siemens motors, can work for a long time, saving the trouble of changing accessories frequently.
9. With a wide range of optional accessories, professional solutions can be developed based on the customer’s budget and processing requirements.
