PZ-5Q Air Mortar Driven Dry Mix Concrete Shotcrete Machine for Coal Gunite
Air motor anti-explosion dry shotcrete spray concrete gunite machine
Product Introduction
1. This Air motor shotcrete machine is mainly used for tunnels, hydro-power engineering, mines, underground engineering, civil engineering, and slope stabilization, etc.
2. It is ideal for refractory material spraying and repair for industrial kilns or the inner linings of kilns.
Main Features
High Efficiency: Highly effective shotcrete machine used for dry-mix, damp-mix shotcreting, and steel fiber reinforced shotcreting.
Non-Adhesion Rotor: Utilizes a new material chamber to completely eliminate bonding and blocking during operation, reducing maintenance periods.
Precision Clamping: A four-point clamping device makes it easy to adjust the pressure between the sealing plate and rotor disk, preventing air and dust leaks.
Steady Conveying: Thin flow conveying method with vortex flow ensures the spraying flow is even, continuous, and steady for superior quality.

Frequently Asked Questions (FAQ)
Q1: What are the main applications of the PZ-5Q shotcrete machine?
A1: It is primarily used for tunnel construction, hydro-power engineering, mining operations, underground civil engineering, and slope stabilization projects.
Q2: Can the machine be used in explosion-proof environments like coal mines?
A2: Yes, the PZ-5Q is air mortar driven (air motor), making it an anti-explosion solution ideal for coal mines and other hazardous underground environments.
Q3: What is the benefit of the non-adhesion rotor system?
A3: The new material chamber in the rotor prevents bonding and blocking during operation, which significantly reduces downtime and the required maintenance frequency.
Q4: What is the maximum conveying distance for this machine?
A4: Both the PZ-5Q and PZ-7Q models can reach a maximum horizontal transmission distance of up to 200 meters.
Q5: Is it suitable for steel fiber reinforced shotcreting?
A5: Yes, the machine is designed to handle dry-mix, damp-mix, and steel fiber reinforced shotcrete effectively.
Q6: How does the four-point clamping device improve performance?
A6: It allows for precise adjustment of pressure between the sealing plate and rotor disk, ensuring zero air and dust leakage while prolonging the life of consumable parts.
