T725 has 3 main parts:
-Slimy materal mixer
in this part water is mixed with some materials like cemen,groutand...in high speed and quality. and the partcles of rock or... to the size of 8 mm can be added to the mixing.in T725 it is possible to mix and maintain 3 type of dry materials with water.
This system can continuously transfer the material and make the mixture with any density. The system is designed in a way that there is no problem for its service and mounting and dismantling. It can be done in no time. There is a water pump installed in the A rock bolt is a long anchor bolt, for stabilizing rock excavations, which may be turned or rock cuts and is an essential component in mining and tunneling.
Rock bolts work by knitting the rock mass together sufficiently before it can more to loosen and also may be used to support wire mesh.
Rock bolts were first used in mining in the 1890 and later were applied to civil tunneling.
Based on their resposibilites, they are used in various sizes and to be stablized them, cement and yrout are applied.
One of the most important method of injection is white wash injection.
T800 is fully automatic, can mix any ratio of water and cement or other materials. An electromotor with a gearbox supplies the required energy for the rotor. Dry materials are guided to the mixer by a rubber duct. Here materials are mixed with water and required water is poured from some opening holes in the mixer.
Then the mixture is guided to the main spiral part of the pump and is sprayed out.
The system can act in any condition by this machine.
The following applications are predicted for the system:
- Injection of rock bolt by paste method with cement or grout.
- Injection of rock bolt by slurry method.
- Using it as a machine for spraying cement mortar or its counterparts such as plaster.

Spare parts for shotcrete machine
The importance quality of spare parts – consumer goods and non – consumer goods – for all experts and engineers have been approved.
T.T.E company for improving the quality of spare parts, rely on two very important point one is enhance the quality based on the feedback reports of workshops and two is lower the price with reference to new technologies and eliminate the human factor in production.
Here are some features of products in this company briefly :
Rubber plate is one of the high consumption of spare parts in shotcrete machine . In order to increase the quality of rubber plates. T.T.E has created a new method that causes the least transformation and avoids the tilt and warp of rubber plate. Also there is possibility to re – use the rubber plate by scouring and smoothing them.
It is notable that the production of rubber cylinders are with one – piece mold that increase the longevity of them. Also the high and low edges of rubber cylinder has some lines which improve the action caulk of rotor.

Shotcrete is spraying the mortar of sand, cement and special additive with the use of compressed air and special machine called Shotcrete Machine.
Shotcreting can be used in building projects to cover the exterior and interior the building with the mortar of sand and cement.
Shotcrete was invented in the early 1900s in America.until the 1950s when the wet-mix process was devised, only the dry-mix process was used. Todays, based on the application in various places, both shotcretes are used in many projects.
Shotcrete set invente d by Carl Akeley in 1909 and introduced at the cement show in New York in 1915 , was a great success and unique as a construction tool, and during 5 years of its careers saw several changes and improvements to suit the mamy user in civil and industrial applications.
Todays, mining companies, contractors and engineers have to rely on quick, effective method of pnewmatically applied concrete known worldwide as shotcrete . It s a key component of many and mining projects . and smart contractors know that if shotcrete is applied correctly using the right equipment, additives and technical support, a solid foundation is built for a successful project. That’s why it is so vital to work with a knowledgeable, experienced shotcrete partner.
The concept of using fibers as reinforcement is not new. Fibers have been used as reinforcement since ancient times, while horsehair Was used in mortar and straw in mud bricks. Today the concept of fiber reinforced concrete has been on of the topics of
Addition of steel fibers into the concrete improves:
- The crack resistance (or ductility) capacity of the concrete.
- The tensile strength of the concrete.
- Toughness, bond strength.
- Flexural and compressive resistance.
- Impact resistance. In result Fiber reinforced shotcrete compare to shotcrete
