Lead Equipment supplies grouting machines for rock cavities and fissures, integrating grout preparation and injection for rock void filling and foundation treatment.

The hydraulic drive and adjustable output capabilities of the plunger-type grout pump enable contractors to adjust the delivery volume based on the required flow rate and pressure during underground construction.

Compared to single-cylinder pumps, double-cylinder high-pressure cement grouting pumps offer more stable flow rates, higher reliability, and more precise pressure control.

Dry refractory spraying machines use compressed air to deliver a dry mixture of refractory materials (such as refractory aggregates, powders, and binders) to the nozzle, where it is mixed with a mist of water and sprayed onto the work surface.

A dry mix gunning machine for refractory is a device specifically designed for spraying refractory materials. It uses compressed air to deliver a dry mix to a nozzle, where it is mixed with water and then sprayed at high speed onto the surface to be sprayed, forming a refractory lining or performing repair work.

High shear bentonite grout mixer features a twin-helix mixing paddle and a bottom scraper design for thorough mixing without dead zones, achieving a bentonite particle dispersion of over 90%.

Dry mix refractory guncrete machine is designed to handle dry refractory mixes (powders or granular materials) and mix them with water at the nozzle before spraying.

A small colloidal grout mixer is a specialized, compact mixing unit designed to produce high-shear, homogeneous grouts—typically cement-based, chemical, or bentonite-polymer blends—with extremely fine particle dispersion and minimal air entrapment.
