Naipu owns most advanced facilities like the VB1000A Vertical Machining Center, TYC-40X4-PCD 8000T Platen Vulcanizing Press, φ4500*17000 Autoclave and so on.




Trommel Screen

Trommel screens, also known as trommels or rotary screens. They are broadly applied in the discharge ends of AG mills, SAG mills and ball mills to classify materials. They are a success in mineral processing plants of non-ferrous metals mines.




• Performance features

Trommel screens (rotary screens) manufactured by Naipu have not only combined characteristics of those trommels around the world, but also possess the technology uniquely developed by Naipu. As a result, our products have features as below:

1. High screening efficiency, less blockage;

2. Simple structure, less space demanded, easy installation and maintenance, no designated driver or power source needed.



• Shapes of Holes in Various Sieve

1. Square holes: mostly applied and accurate, suitable for screen-separating of regularly-shaped particles

2. Rectangular holes: when thicker screen wires are used, the precision rate drops due to high hole-opening rate and high throughput.

3. Long three-weft holes: It has the highest hole-opening rate, but has a poor precision rate, if used by shifting it by 90 degrees, the precision rate will be improved, owning to the long holes and the vibration of screen wires, blockage does not tend to occur long three-weft holes

4. Round: long service life, high precision, easy to be blocked; poor efficiency and low conveying capacity.

5. Triangle: High precision, high efficiency, poor capacity in anti-blockage and conveying, and holes enlarged after wears.

6. Equilateral triangle| grizzly type: Conveying capacity increases with the increasing of the height of rods, and the efficiency slightly drops when the rods become straight at both sides, and blockage gets worse.

7. Guide-track type: Normally it is combined with a grizzly in order to protect the rods and reduce the wear.

8. Angled arrangement: It can be used on any horizontal screen so as to increase the conveying capacity.

9. Loose rod arrangement: It can reduce blockage, but has a poor precision rate.

Rubber Liners

Wear resistant rubber liners manufactured by Naipu are widely used in non-ferrous and ferrous metals mining, coal and power plants. Gradually rubber liners are replacing traditional cast steel liners, winning users' positive comments. After long term of R&D, design and test, Naipu has successfully applied rubber liners, composite liners and rubber trommel screens in ball mills, SAG mills and AG mills, and has achieved significant tech breakthrough and innovation. 



• Mill Spares (Ball, AG, SAG Mill)


• Rubber liners

NAIPU lifters are made of tough abrasion resistant rubber with decades of proven field use, guaranteeing their ability to withstand the relentless pounding of mill action. They are available in a selection of profile designs and heights to give unexcelled performance under various grinding mill conditions.

NAIPU's rubber liners are designed and arranged so that the lifter bars can be easily replaced without affecting the shell plates, which can outlast lifter bars by at least two to one. Our lifter bars are engineered to be compatible with most shell and end liner plate designs.



• Performance Features

Rubber Mill Liners are chosen for most primary, secondary and tertiary ball mills. And in many cases rubber components are best suited for specific areas in AG and SAG mills.

Naipu has supplied complete rubber linings in some of the largest ball mills for CITIC Heavy Industries from China and others. We have supplied Rubber Liners for more than 100 mills worldwide.

1. High abrasion resistance, with service life 1.5 times longer than that of metal ones.

2. Lower noise by 8-10db than that of metal ones.

3. Light in weight, resulting in easy installation and disassembling (taking only 1/3 of the time needed for installing or removing metal liners).

4. High price/performance ratio
