WHB-300 Type Lime-Soil Mixer (Soil Screener): The batching and metering assembly adopts belt-flow metering, featuring accurate batching and convenient operation and maintenance. The production efficiency can be adjusted within a certain range through the gate plate below the discharge outlet (a screw rod adjusts the valve opening height). A screen mesh is installed above the hopper to prevent oversized main and auxiliary materials from entering. Mixing and screening adopt a continuous rotary self-falling drum type, with strong separation capability and high mixing uniformity; the screened particle size is ≤15mm. A side-wall vibrator is installed on the side wall of the loess hopper to prevent arching. The front and rear frames of the external transport secondary conveyor are hinged, and it can be hoisted to a vertical position during transportation. Designed maximum production capacity: 300 tons or 200 cubic meters per hour; overall dimensions 7.3×2.9×3.3m; total machine weight 7.6t; mixing particle size ≤20mm; uniformity ≥90%; total machine power 27kW; loess storage 7.5m³, white lime storage 4m³; loess/white lime/external transport conveyor motors 5.5/3/4kW, rotary screen motor 5.5kW, bin wall vibrators 0.75kW×3, each conveyor uses UCP310 bearings and 20A chains. It integrates storage, batching, screening, mixing, and transport, and is mainly used in various building foundation engineering constructions.
