Application:
QVC Series Pneumatic vacuum loading machine is used in automatic material for Tablet Press machine, Pulverizing machine, capsule filling machine, Screen machine, Packing machine, Pulverizing machine, Screen machine and Mixing machine etc. It doesn't need any mechanical vacuum pump, so it is simple structure, small volume, without repairing, no noise and easy being controlled. It can be stopped separating layer for the feeding material because the machine has high vacuum. QVC Series Pneumatic Vacuum Conveyor was designed according to international standard. It is easy cleaned and beautiful. It meets GMP requirement.
Characteristic:
Solve the problem thoroughly about the separating layer of material.
The sintered-metal filter is Japanese original.
It can be removed the material static electricity.
It is airtight without crossed contamination.
It is made in good quality stainless steel(304 and 316L).
It is made in non-toxic and corrosion resistant material.
Filter is easy cleaned.
It is controlled intelligently and automatically.
It is easy dismantled with building blocks structure.
It is easy set up and small volume, the weight is light
It is no noise and screening
It is economical and practical the cost is lower.
Working Principle
Vacuum feeder is a vacuum loading machine by using pneumatic vacuum pump as vacuum source. With this vacuum feeder materials could be fed directly from container into mixer, reactor, hopper, sheet press, packing machine, vibrating griddle, pellet trimming machine, hydro-state pelleter, dry-state pelleter and disintegrator. To use this feeder could lighten workers' labor intensity, put an end to powder pollution and ensure that the production process meets GMP requirements.

Cold drawn steel bar is produced by Hot Rolled Steel Bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
