Product Overview
Dry and Wet Concrete Spray Shotcrete Gunite Machine for Mining
Dry mix shotcrete machine use air pressure to convey dry material from the machine through the hose to the nozzle where water is added. PZ Series dry mix shotcrete machine is a low to high production, continuous-feed material placement unit for dry-mix gunite or refractory materials. It is equally at home underground in a mining environment as it is on a construction jobsite. This kind gunite machine has a rotor feed system, which stands up job-after-job to ensure a long service life with low maintenance. Several hose and nozzle options are available to meet the demands of every gunite / shotcrete spraying application.

Frequently Asked Questions
What materials can the PZ series shotcrete machine handle?
The PZ series is designed for dry-mix concrete, gunite, and refractory materials. It can handle a material ratio of cement to sand between 1:3 and 1:5.
What is the maximum conveying distance for these machines?
The machine can transport materials up to 200 meters horizontally and up to 50 meters vertically, making it ideal for deep mining and high-rise construction.
Is the machine easy to maintain?
Yes, the direct rotor-type material chamber is designed for smooth discharge and prevents blocking, which significantly simplifies cleaning and daily maintenance.
Does the machine support different power voltages?
The standard configuration is 380V. However, for specific project requirements, we recommend consulting our technical team regarding motor customization options.
What are the primary safety features?
The machine includes a reinforced safety frame and a sturdy body design to protect operators from accidental hazards and ensure stability during high-pressure operation.
How does the dry-mix shotcrete process work?
It uses air pressure to convey dry materials through a hose to the nozzle. Water is then added at the nozzle head just before the material is sprayed onto the surface.
