    Control charts are a method that uses statistical principles. This principle is often used in quality control work to perform process capability analysis and process analysis.
    (two) control principle
    When the project implementation process is in a normal state, the project's operational activities are stable, or a process that operates according to standardization. At this time, most of the quality control points should be within a certain small boundary (this boundary usually adopts ±3 times standard deviation, if the requirement is low, it can be enlarged), or the arrangement has a regularity. The higher the quality level, the less likely it is that the control boundary or the alignment is defective; and once the point exceeds the control limit or the arrangement is defective, it can be considered that the good condition and standard operating conditions for maintaining the normal operation of the project are highly likely to have been damage. Therefore, it is possible to control the quality through the control chart reflecting the quality state, that is, to measure the quality point in the process, and when an abnormality is found, it is possible to further observe, investigate, clarify the cause of the abnormality, and take measures to eliminate the abnormal factor; Conversely, if the control point is normal or normal after the measure, the effect of good control can be obtained.
What is plastic granulator?
Plastic Granulator,also popular as crusher or grinder,is size reduction machine used for granulating various materials into small and uniform particle sizes.It is widely used in waste recycling industry,especially in plastic recycling field.
Plastic grinder machine is ideal for crushing bulk waste materials such as various scrap plastic products,like PET,HDPE,PP,PE,PVC,These waste plastic material normally are in the form of injection/extrusion runners,plastic pipes,film,PET bottles,HDPE containers,nylon strips or pipes,so on and so forth.Besides used in plastic recycling field,granulator is also available for crushing many other types of waste material such as paper,rubber,etc.
Granulator can be used as standard equipment.Or you can connect it with a feeding conveyor and even shredding and baling machines to compose production lines.Some heavy duty granulators with high output rate are quite commonly applied in recycling lines such as RDF line.They are usually positioned behind the shredders as as secondary granulating process to get smaller and uniform sized articles.
RHONG have many different kinds of plastic granulators for your choice to crush different waste material,as for the details,pls see following:
(1)Sound proof granulator good features as following:
A:Fully airtight silent designed,noise below 80dba without 1 meter away from the machine,avoids powder contamination
B:stainless steel material suction spout easy for cleaning and re-move
C:Installed with safety protection system and CE electrical appliances meeting the European safety standard for your optional purchase
D:Installed with electrical phase controller and power isolator,safety operation and simple maintenance
(2)Middle speed granulator good features as following:
A:suitable to be installed beside the machine,combination with a cyclone separator and dryer to form a rapid recycling system.It eliminates the complex intermediate links,and avoids manpower and material waste.Hence ensures maxium recycling efficiency
B:suitable for spot recycle of srape products of small plastic bottles,containers,pellicle plastics,sheets,sprues from injection molding machines and extrusion parts,tailored to an extremely wide range of application.
C:middle speed granulator has characteristics of low noise,dust free,occuping small space,engery efficiency and able to operate for long hours continuously,with high efficient environment protection.
