A vertical injection grout pump is a high-pressure grouting device specifically designed for vertical grouting operations. Its core function is to precisely inject grout (such as cement grout, chemical grout, etc.) into foundations, soil layers, or building cracks using high pressure to achieve engineering purposes such as reinforcement, seepage prevention, and leak sealing.

High-pressure grouting pumps, based on high-pressure jet grouting technology, are used in drilling rig applications to achieve foundation reinforcement through the coordinated operation of the high-pressure pump and the drilling rig.

Grouting pumps inject cement-based or chemical grout into foundation cracks, pores, or weak layers under high pressure, forming a solidified mass to enhance the foundation’s bearing capacity. Its reinforcement principles encompass the following aspects:
Permeation consolidation: The grout fills soil pores, increasing density through cementation; suitable for highly permeable strata such as sandy soil and silt.
Fracturing reinforcement: High-pressure grout fractures the soil, forming a dendritic grout vein network, improving the overall strength of the foundation; commonly used for soft clay or collapsible loess.
Compaction grouting: High-pressure compaction of the surrounding soil creates a dense zone; suitable for saturated soft clay or artificial fill.

A high-pressure cement grouting pump is an industrial device that delivers cement grout (or chemical grout) under high pressure. It is widely used in engineering fields such as foundation reinforcement, seepage prevention and plugging, and structural reinforcement. Its core function is to inject grout under high pressure to fill voids in soil or concrete structures, forming a stable composite structure and improving the load-bearing capacity and durability of the project.

A high-pressure vertical grout pump is a specialized positive displacement pump designed to inject grout (a mixture of cement, water, and often additives) into cracks, voids, and fissures under high pressure. Applications: Soil nailing & ground stabilization. Tunneling and mining grouting. Dam and foundation repair. Post-tensioning duct grouting. Void filling beneath slabs or structures.

Refractory gunning machine uses high-pressure spraying of refractory materials to quickly repair the refractory layer of high-temperature components such as kiln linings, preheaters, and coolers. Their core advantages lie in efficient repair, reduced downtime, and lower labor intensity. They are particularly suitable for partial or overall refractory layer maintenance of equipment such as rotary kilns, decomposition furnaces, and grate coolers in cement plants.

250kg capacity refractory mixer and gunning machine is the specialized piece of equipment used in industrial applications—particularly in steel, cement, petrochemical, and power generation industries—for mixing and applying refractory castables or gunning mixes onto furnace linings, ladles, kilns, or other high-temperature structures.

The main applications of cement grout pump stations include:
Foundation reinforcement: Grouting for foundations in dams, tunnels, mines, etc., to improve bearing capacity.
Structural repair: Reinforcement of buildings and bridges, foundation lifting, soil compaction grouting, etc.
Underground engineering: Tunnel lining, contact grouting, and tunnel waterproofing.
Marine engineering: Underwater foundations, wharf scour protection, shoreline reinforcement, etc.

A cement bentonite grout mixing plant is a specialized system designed to produce homogeneous, stable slurries used primarily in geotechnical and civil engineering applications such as: Slurry walls (diaphragm walls), groundwater cutoff, tunneling and shaft sealing, landfill containment barriers, and soil nailing and ground improvement. Working Principle: Premixing Stage: Bentonite and water are thoroughly dispersed under low-speed stirring to form a colloidal solution.
Main Mixing Stage: Cement and additives are added, and homogeneous mixing is achieved through high-speed shear mixing.
Transportation and Storage: The mixed slurry is transported to the construction site via a pumping system or temporarily stored in mixing tanks to maintain its fluidity.

The grout pump and mixing station is an integrated device combining a mixer, mixing tank, and grouting pump. It injects cement-based or chemical grout into strata, structural fissures, or soil and rock masses under high pressure to achieve reinforcement, seepage prevention, or filling functions. Its working principle can be divided into three stages:
1. Cement grout preparation: A high-speed vortex mixer rapidly mixes cement, bentonite, and water, forming a homogeneous grout within 10 seconds, preventing particle sedimentation.
2. Cement grout storage: The mixing tank continuously agitates the grout to prevent solidification and ensure a continuous supply.
3. High-pressure grouting: A hydraulically driven pump generates high pressure through piston or plunger movement, injecting the grout into the target area. The pressure range is 0-45 Bar (some models reach 0-100 Bar), and the flow rate is 0-100 L/min.

6000L capacity tank soil seed spraying machines mix seeds, fertilizer, mulch (such as wood fiber or pulp), and water into a slurry, which is then sprayed evenly onto the soil surface under high pressure. The mulch protects seeds from rain and wind erosion while maintaining soil moisture and promoting germination. Small hydroseeding machines are suitable for applications such as slopes, mine reclamation, and river management, rapidly establishing a vegetation layer to reduce soil erosion. For example, in hard or acidic soils, a binder can be added to enhance slurry adhesion. They support various terrains, including slopes (up to 60°), rocky slopes, and infertile soils. Some models are equipped with diesel engines for use in harsh outdoor environments.

A hydraulic high-pressure horizontal cement grouting pump is a specialized device driven by a hydraulic system to inject cement slurry and other readily setting materials into rock formations, soil cracks, or gaps in building structures at high pressure. The core principle is based on hydraulic transmission and the reciprocating motion of a plunger:
Hydraulic drive: An electric motor drives a gear pump, which delivers high-pressure oil through a relief valve and into a hydraulic reversing valve block, controlling the reciprocating motion of the hydraulic cylinder.
Synchronized grouting: The hydraulic cylinder and the working cylinder move synchronously, with suction and discharge valves at each end. This allows for single-liquid or dual-liquid grouting (e.g., a mixture of cement slurry and water glass).

Today, our factory shipped four GZ-3ER refractory gunning machines. These gunning machines use compressed air to spray a precisely proportioned mixture of refractory materials at high speed, forming a refractory coating on the surface being sprayed. Their significant advantages, including rapid application speed, high efficiency, and high-quality work, have led to their widespread adoption. Refractory gunning machines are primarily used in the following applications:
1. Metallurgical Industry: Hot and cold repairs of blast furnaces, ladles, and converter linings.

5. Decoration Engineering: Relief coatings, handicraft spraying, and rockery shaping.

Plastic tank hydro seeding machine uses a tank made of plastic (typically high-density polyethylene or HDPE) instead of traditional materials like steel or fiberglass. These machines are used to spray a slurry mixture of seed, mulch, fertilizer, water, and sometimes tackifiers (to prevent runoff) onto soil for landscaping, erosion control, and revegetation projects.

Refractory gunning machines for repairing EAF use compressed air or a mechanical pump to mix refractory materials (such as magnesia and alumina-magnesia gunning materials) with water or a binder, then spray them at high speed onto the worn areas of the electric arc furnace lining, forming a dense repair layer. For electric arc furnace (EAF) gunning repairs, we recommend using refractory gunning machines with high-pressure output, wear-resistant nozzles, automated control, and explosion-proof design. Their core function is to repair the furnace lining by spraying refractory materials at high pressure, and key parameters must be compatible with the high-temperature, high-wear environment of the EAF.
