Overview of Centrifugal Spinning Concrete Pole Machine

Centrifugal Spinning Machine for Prestressed Concrete Electric Spun Pole
SL Centrifugal Spinning Machine for spun concrete Electric pole & pile is driven by speed regulation DC Motor. The spinning process is automatically controlled with a simple push button control panel.

High centrifugal force extracts the excess water from fresh concrete placed in the concrete pole mold. This process makes the concrete extremely compacted which in turn improves the quality of concrete character. Concrete poles will have smooth surface with void cross-section.

The spinning process starts with slow revolution. The concrete will be distributed uniformly over the whole mold. Following that, the revolution increases automatically to medium speed and finally to high speed. At the highest speed, a large magnitude of centrifugal force (~30g) acts to compact the concrete. This period will take about 15 minutes.

2 concrete electric pole Length: 6-18m

Working Principe

1. The steel mould should work together with pole spinning machine. The steel mould should be placed on the spinning machine smoothly.

2. Put the mixed slurry into the mould and rotate in different directions under the motor driven.

3. In this process, the redundant water in the concrete is released by the force of centrifugal, and the concrete is dense and high strength. And then, the pole forms around the inner wall of the pole mould.

Technical Parameter of concrete electric pole making machine

Features

1. Advanced Welding technology, which enhances smooth finish of the mould wall and surface and eliminates uneven traces of rivet holes.The surface of concrete poles  will be improved obviously.

2. The pole mold cylinder is changed to U-type longitudinal stiffeners. This structure can greatly increase the stiffness and flexural strength of the steel mould.

3. Install the slot with rubber sealing strip, in order to prevent leakage to ensure quality.

Concrete Pole Production Process

1. Raw Materials Preparation

prepared raw materials required for the producing of cement poles.Production raw materials include: steel, sand, gravel, and cement.We should choose high quality steel bar, cement that is strong resistance to pressure,choose fast solidification and low density cement.Sand should be filtered to prevent other magazines doping.

2 Steel Cage Forming Process

Use straightening & cutting machine to straighten and cut steel bar in accordance with the provisions. After finishing straightening steel bar,send them to the next program.Please note that the straightening of steel should be cut off according to the length of cement pole. Length should be accurate. It is crucial for the steel bar is equivalent to concrete pole skeleton .

3. Tension Steel Cage 

4. Concrete Distribution Process

Place the steel cages in the open mold .After pouring with cement with concrete distribution machine , cover the cover mould.After confirmation on both sides of the gap smaller or closed, finally plug two sides with pouting lips fortress to prevent the outflow of cement.

5. Centrifugal Spinning

After closing the mold and hoist with crane onto the spinning machines . Then start the spinning process . It will take three different speed regulating steps , totall 15 minutes . At this step , speed variable control cabinet and motor is suggested .

6. Steam Curing 

It's one of most imporatant process for the concrete pole production . With the steam supplying into the steam curing pool by the steam boiler , the concrete poles in the mold will be treated with four hours at least in the pool . At different period , concrete poles will need different temperature .  And at about 86 degree , the temperatue should keep steady .

7. Inspection of Finished Concrete Poles

8. Storage of Qualified Concrete Poles

We supply complete concrete pole machines and be responsible for installation and commissioning and also workers production training service .
