Product Characteristics：
1.Mixing system:
The mixer is a single-shaft screw belt mixer. It has many of advantages such as: high stirring efficiency,no dead zone, good mixing uniformity. Besides, the driving mode is direct drive of motor reducer;and the drive can realize forward and reverse function;the transmission is stable,;the operation is reliable; The shaft end seal adopts the double seal structure that the labyrinth seal and one-way seal is combined. The seal is reliable and does not leak slurry. The discharge gate adopts the structure of pneumatic automatic controlling gate valve. The discharge gate has good sealing performance, convenient maintenance, no slurry leakage, and adjustable speed of discharging ; A sieve device is added in the mixing chamber to filter particles larger than 6mm in diameter.2. Grouting pump:
The grouting pump adopts the adjustable stator technology of single-screw pump; the pumping pressure is adjustable; the energy consumption is small; the efficiency is high; the rotor adopts nanotechnology, has excellent wearing resistance and long service life; the grouting pump adopts frequency conversion control; The pumping flow rate and speed are adjusted in real time, and the reverse pressure relief function is adopted; the hopper is lined with a nylon plate structure, which is not filled and glued, and is easy to clean; the outlet is equipped with a diaphragm type pressure gauge to monitor the pumping pressure in real time; The hopper has a built-in screw feeding device, which feeds evenly, and the pumping is continuous without pulse phenomenon. The hopper is equipped with a sieve to prevent large particles from entering the grouting pump.3.Control System:
The complete set of equipment adopts centralized control ，fabric point remote control ，and anchor trolley operation room bypass control mode for design, centralized control including the control of equipment's total power, mixer start and stop, grouting pump start and stop;forward and reverse, frequency conversion of the grouting pump.The remote control of the cloth point and the bypass control of the bolt trolley operation room are mainly to control the start and stop of the grouting pump, so as to control the grouting amount of the bolt to achieve the purpose of precise grouting.Technical parameter
