TK700 Wet Shotcreting Machine

TK series rotor-piston type wet shotcreting machines are CRAC’s significant scientific research achievements with independent intellectual property rights. With the unique feeding device composed of rotor, piston and cam, it achieves conveying of plastic concrete in the uniform thin flow process.

The products have been awarded the 2nd prize of Science and Technology Progress Award of Ministry of Railways in 1998, the 3rd prize of National Nature Sciences Award in 1999, and selected into National Key & New Products Plan in 1999 and 2000. By 2010, TK series wet shotcreting machines have already been listed in the equipment procurement catalog of CREC.

The products have the following characteristics:

Key technologies

Anti-sticking technology: the problem of material sticking in chamber is resolved by forced pumping concrete via the piston.

Uniform thin flow technology: conveying of plastic concrete in uniform thin flow process is achieved by feeding concrete into three material chambers radially and simultaneously.

Accelerator adding and controlling technology: the dosing pump is accurate and adjustable; the homogenous mixing of concrete and accelerator can be achieved by atomizing jet and high-quality spraying at the nozzle
