Small RMC Plant
Products Description
AGICO Small RMC Plant is a compact ready-mix concrete batching system with a capacity range of 20–60 m³/h. Two configurations are offered: the stationary HZS series and the towable YHZS mobile series. Every unit is equipped with a JS twin-shaft forced mixer as standard and a digital weighing system using RS485 load cells connected directly to a Siemens PLC.
AGICO has served the cement and concrete equipment industry for over 20 years, holding CE and ISO 9001 certifications. More than 1,000 units have been delivered to over 30 countries. Typical applications include small-scale commercial RMC start-ups, precast factory feeding lines, and on-site batching for remote mining projects.
Products Details
The plant uses a vertical layered layout with a gravity-flow material path. Aggregates are loaded into batcher bins by a wheel loader. The PLC opens pneumatic butterfly valves sequentially to release each aggregate type into the weighing hopper according to the preset mix design. Cement is simultaneously conveyed from the silo to an independently suspended powder scale by a screw conveyor, while water and admixtures are pumped into separate metering vessels. After all four material groups are weighed, the PLC initiates charging in the order of aggregates, cement, then water and admixtures into the twin-shaft mixer. Forced mixing lasts 45 seconds before the hydraulic discharge gate opens. The finished concrete slides through a discharge chute into a transit mixer truck. One complete batching cycle takes approximately 72 seconds.
The major sub-systems are configured as follows: the aggregate batching unit uses a PLD-series batcher with 2–4 bins, each holding 4.5–15 m³; the powder system consists of bolted silos (50–200 t) and Ф219/Ф273 screw conveyors; the water system uses a stainless steel weighing tank with gravity feed and a pneumatic shut-off valve for double interruption; the mixer is a JS-series twin-shaft forced type with high-chrome wear-resistant cast iron arms and liners, plus a multi-labyrinth air-sealed shaft-end design; the electrical system is built around a Siemens S7-1200 PLC, supporting over 200 mix recipes and Ethernet-based remote diagnostics.
Products Features
±1% Cement Weighing Accuracy - Digital load cells transmit RS485 signals directly to the PLC. Intermediate analog signal loss is eliminated. Batch-to-batch deviation is tightly controlled, and annual cement waste is reduced by over 10 tons.
Twin-Shaft Mixer as Standard - The JS500 forced mixer is fitted from the smallest AG-HZS25 model. Mixing uniformity reaches ≥95% within 45 seconds, and the segregation issues common to reversible drum mixers are avoided.
Q345B Bolted Steel Structure - All main joints are connected with Grade 10.9 high-strength bolts. On-site welding and NDT are not required. Installation is completed in 5–7 days, and the structure can be fully disassembled and reused after relocation.
8 mm Silo Cone Wall Thickness - The cone section is rolled from Q345B steel plate. Compared with the industry-standard 6 mm design, the corrosion allowance is increased by 50%, and mid-life cone replacement is effectively avoided.
Pre-Wired for Target Grid - The control cabinet is pre-wired and power-tested before shipment to match the destination country's voltage. Three grid standards (380V/440V/480V) are supported, and the HMI is preloaded with a six-language interface.
20 Years of Heavy Equipment Expertise - The quality system is built on rotary kiln and ball mill EPC experience. The weighing platform uses a 1.5× dynamic load safety factor, and all structural welds undergo 100% ultrasonic testing.

FAQ
Q: What is included in AGICO's FOB quotation? How are shipping and customs handled?
AGICO's standard FOB quotation covers the main batching plant, batcher, screw conveyors, control cabinet, and standard silo, including factory packing. Ocean freight, destination customs clearance, local foundation work, and installation are excluded. AGICO provides a complete export documentation package, including a commercial invoice, packing list, certificate of origin, and bill of lading. Third-party pre-shipment inspection by SGS or BV can be arranged upon request. For first-time concrete equipment importers, AGICO can recommend partner freight forwarders and estimate shipping lead times and destination port charges.
Q: Who handles installation and commissioning after the equipment arrives? Is an on-site engineer required?
Two installation plans are offered by AGICO. The standard plan is remote-guided installation. A bilingual installation manual, foundation drawings, and step-by-step videos are shipped with the equipment. The customer assembles the units by part number while an AGICO engineer guides torque checks and power-on testing via video call. The premium plan involves on-site deployment of one mechanical engineer and one electrical engineer, who complete installation and 72 hours of continuous trial production over a 10–14 day service period. Both plans include operator training and one month of online support.
Q: Does AGICO provide custom configurations for its small RMC plants?
Flexible configuration is supported based on standard models. Adjustable items include the number of aggregate bins (from 2 to 4), silo capacity (50 to 200 tons), feeding method (skip hoist or inclined belt), and control system (standalone PLC or networked with a 4G DTU remote management module). AGICO can also pre-load mix recipes to match the customer's local concrete standards before shipment. For special environments-such as high-altitude sites where motor derating is required, or coastal saline-mist areas where the control cabinet can be upgraded to a stainless steel enclosure with IP65 protection-adaptive designs are available.
Q: What after-sales support and technical response time does AGICO offer?
A 12-month full warranty is provided from the bill of lading date, with lifetime technical support. The after-sales response operates at three levels: routine technical inquiries are handled in real time via email or instant messaging; equipment fault diagnosis is performed by an engineer accessing the PLC remotely, with most issues identified within 4 hours; for replacement parts, AGICO maintains inventory of common wear items-mixing blades, liners, load cells, solenoid valves, and PLC modules-shipped within 48 hours of order confirmation. For manufacturing defects covered under warranty, AGICO provides replacement parts free of charge and covers air freight costs.
