high quality prestressed spun concrete electric pole machine

Reinforced cement pole machines is used for concrete electrical pole manufacutring. Its mainly manufacture technology is longitudinal tension by steel wires. During rotation of mould,  it can squeeze out the excess water contained in concrete under centrifugal force. Thus, it can greatly improve the concrete density and strength.

• 1. Overview of Concrete Spun Pole Spinning Machine

Centrifugal spinning machine for prestressed spun concrete electrical pole is a kind of mold supporting

equipment used for producing reinforced and prestressed concrete poles and other cement

products with a variety of different diameter and length.

Centrifugal spinning machine for prestressed spun concrete pole is operated by remote-control stepless

continuously variable speed motor. It runs smoothly and has a variable-speed range. So the production

of concrete pipes are good of quality.

The steel base of the machine is welded in box-type structure with feature of sturdiness and durability.

The bearings are well sealed and reliable, long service. Random electric control equipment is complete

and easy to operate.

• 3. Features of Concrete Spun Pole Spinning Machine

3.1 Saving a great deal of steel, about 30~70% (employ cold-drawn steel wire can save 30%~60%; employ

high stress steel wire can save 40%~69%).

3.2 Crack resistance can increase by about 3~5 times.

3.3 Rigidity increases 1~3 times.

3.4 Reducing the cost (using cold drawn steel wire can reduce 25%~40%; using high stress steel wire can reduce 12%~21%).

3.5 Good durability, can delay the existence and expansion of cracks.

3.6 Protect the environment on which human beings depend on for existence, and reduce the deforestation.

• 4. Working Principle of Concrete Spun Pole Spinning Machine

4.1 Adding the slurry into the steel mold for concrete pole, it is driven quickly and rotating at the same speed

of the machine. Each component is separated and released under the centrifugal force. Usually the higher the

slurry rotate speed, the better the slurry separating effect.

4.2 Centrifugal sedimentation is the use of different density of each component in the slurry, which is rotated

under the centrifugal force. To realize the liquid - solid (or liquid - liquid) separation.

4.3 The speed of separation is slow when the viscosity of slurry is high.

4.4 It is good for centrifugal sedimentation when the slurry density is different in each component.
