Fully Hydraulic System Shotcrete Machine Mini Concrete Dry Shotcrete Machine

It is a fully hydraulic, dry-mix (dry shotcrete) machine designed to convey and spray dry mortar/concrete mixes using compressed air and hydraulic power.

Under optimal conditions the machine can convey material up to 200 m horizontally and 50 m vertically; many site layouts use distances around 100 m. Actual achievable distance depends on mix, hose layout, compressor, and nozzle settings.

Rated throughput is 7 m3/hour, though actual output will vary with material mix, operator skill, hose length and diameter, and job conditions.

This machine is suitable for typical dry shotcrete mixes; a commonly recommended ratio is cement:sand = 1:3.5. Do not exceed the specified maximum aggregate size of 20 mm.

The unit is powered by a 4 kW motor and requires a 380 V three-phase electrical supply. Confirm site power compatibility before delivery.

Air consumption is specified at 7–15 m3/min. Select an air compressor that meets or exceeds this flow rate and provides adequate pressure for dry shotcrete operations.

The machine is specified for a hose inner diameter of 57 mm; use compatible, durable shotcrete hoses rated for dry-mix spraying.

The machine weighs approximately 700 kg and has compact dimensions (1650 x 800 x 1280 mm), making it relatively easy to move with light lifting equipment or on a small trailer.

Core components include the hydraulic pump and gear system. Common spare parts include wear plates, nozzles, hoses, lining, seals and hydraulic filters—keep these on hand for fast maintenance.

Yes; the product supports customizable color options and can typically be fitted with optional accessories or controls. Contact the supplier for specific customization options and lead times.

Typical applications include tunnel and underground construction, shotcreting of building projects, concrete repair, foundation and retaining wall construction, and filling voids in mining or civil works.

Regular tasks include daily cleaning of the hopper and hoses, inspection of wear parts (nozzle, hoses, lining), checking hydraulic fluid level/condition and filters, and periodic replacement of wear items per operating hours. Follow the manufacturer's maintenance schedule for intervals.

Yes—operators should be trained in dry shotcrete techniques and machine operation. Recommended safety measures include wearing respiratory protection, eye/face protection, hearing protection, and following safe handling procedures for compressed air and hydraulic systems.

Warranty terms, after-sales support and spare parts availability vary by supplier; contact your vendor or the manufacturer (brand: earlybird, model EB-7) to obtain warranty details, service contacts and to order parts.
