The heavy ammonium nitrate oil truck consists of a truck chassis, latex storage and conveying system, sensitizer storage and conveying system, accelerator storage and conveying system, porous granular ammonium nitrate storage and conveying system, diesel storage and conveying system, pump filling and mixing conveying system, screw conveying and filling and mixing conveying system, transfer hopper, drum winding and unwinding system, hydraulic system, and electrical control system, etc.  

2. Process Introduction and Flow The heavy ammonium nitrate (HAM) oil tanker can flexibly adjust the loading ratio of latex matrix and porous granular ammonium nitrate in its hopper according to changes in blasting conditions and requirements. It loads latex matrix, porous granular ammonium nitrate, sensitizer, accelerator, clean water, diesel fuel, etc., in the specified proportions before driving to the blasting site to adapt to different mine needs.

One HAM oil tanker can produce pure emulsion explosives, pure HAM explosives, pumpable HAM explosives with ≤30% porous granular ammonium nitrate, and HAM explosives with >30% porous granular ammonium nitrate, offering flexibility and mobility.

The HAM oil tanker allows for manual setting of the HAM oil ratio. When pure emulsion explosives or pumpable heavy ammonium nitrate explosives with porous granular ammonium nitrate content ≤30% are mixed at the production site, the pumping and mixing system is automatically configured to fill the blast holes; when pure ammonium nitrate explosives or heavy ammonium nitrate explosives with porous granular ammonium nitrate content >30% are mixed at the production site, the spiral mixing and conveying system is automatically configured to fill the blast holes.

4. Technical Advantages The  BCZH-15 on-site mixing multi-functional (heavy ammonium nitrate oil) explosives truck features safety, intelligence, stability, controllability, convenient operation, accurate metering, high efficiency, and low consumption. Its main technical features are as follows:

(1) Unique Silo Structure The silo's overall appearance is teardrop-shaped, improving the flowability of latex matrix and ammonium nitrate particles within the silo and reducing their excess volume. The teardrop shape also increases the strength and rigidity of the tank itself, improving the mixing truck's performance while extending the silo's service life by 30%. The silo is made of high-strength aluminum alloy, meeting the requirements for corrosion resistance and loading strength of the loaded materials. The design process underwent professional strength verification and calculation, and excellent processing technology fully guarantees welding, installation quality, and service life. It is very suitable for vehicles traveling on bumpy mining roads .

(2) Convenient Switching Between Multiple Types of Explosives The heavy ammonium nitrate (HAA) oil tanker can flexibly adjust the loading ratio of latex matrix and porous granular ammonium nitrate in its hopper according to changes in blasting conditions and requirements, adapting to different mine needs. Compared to hoppers with fixed loading types, this truly achieves full coverage of HAA oil explosive production needs, from 0% to 100% latex matrix content, all from a single tanker.

Based on the rock characteristics and blasting requirements of each borehole, the type or density of explosive to be produced can be selected with a single click. The system automatically starts the corresponding equipment and initiates closed-loop control. This not only enables quick switching between different types of explosives in different boreholes but also allows for energy matching by loading different types of explosives into the same borehole based on rock variations, achieving optimal blasting results. Depending on the characteristics of the ore, different types of explosives can be loaded into a single borehole. For example, emulsion explosives can be loaded at the bottom of the borehole, pumpable heavy ammonium nitrate oil can be loaded in the middle, and porous granular ammonium nitrate oil can be loaded at the top (as shown in the diagram below). First, set "Porous Granular Ammonium Nitrate (0%)" and the loading amount in the control interface. Place the loading hose at the bottom of the borehole, start loading, and the system will automatically load and retract the hose, stopping automatically when the set loading amount is reached. Then, modify "Porous Granular Ammonium Nitrate (20%)" in the control system interface, set the loading amount, start loading, and the system will automatically load pumpable heavy ammonium nitrate oil, stopping automatically when the loading amount is reached and retracting the loading hose. Finally, swing the mixing auger above the borehole, set "Porous Granular Ammonium Nitrate (100%)" in the control system interface, set the loading amount, start loading, and the system will automatically load porous granular ammonium nitrate into the borehole, stopping automatically when the loading amount is reached. This efficiently and quickly achieves the loading of three types of explosives into a single borehole. For example, the loading method for two different densities of heavy ammonium nitrate (HAM) explosives in a single borehole (as shown in the figure below): First, set "porous granular ammonium nitrate (30%)" and the loading amount on the control interface. Place the loading hose to the bottom of the borehole, start loading, and the system will automatically load and retract the hose, stopping automatically after reaching the set loading amount. Then, modify "porous granular ammonium nitrate (70%)" on the control system interface, set the loading amount, start loading, and the system will automatically load HAM explosives via a screw, stopping automatically after reaching the loading amount. This efficiently and quickly achieves the loading of two types of explosives in a single borehole.

(3) Top-mounted screw and double-drum configuration improve loading efficiency. The HAM explosive truck adopts a top-mounted screw design. When producing HAM explosives or HAM explosives (porous granular ammonium nitrate > 30%), the top-mounted screw can rotate freely 350° to locate and load the explosives, with a working radius of up to 5 m, significantly improving working efficiency. An automatic hose reel system is installed at both the rear and front of the vehicle. When loading emulsion explosives or pumpable heavy ammonium nitrate explosives at the front, the front-end hose is used; when loading at the rear, the rear-end hose is used. The reel automatically retracts during the loading process, allowing one person to operate the entire operation without the need for personnel to drag the hose to the front or rear, reducing manpower and improving efficiency.

(4) PID Closed-Loop Control System and Accurate Explosive Measurement

The electrical control system uses a PLC, an IFM electromagnetic flowmeter, and a speed sensor with 180 pulses per revolution. It achieves PID closed-loop proportional control according to the process formula. This advanced control system ensures accurate measurement of each conveyed material according to the set process ratio during the production of pure emulsion explosives, pumpable heavy ammonium nitrate explosives, and pure ammonium nitrate explosives, as well as screw conveyor heavy ammonium nitrate explosives, accurately measuring the filling amount of the boreholes. The hydraulic system uses an advanced manual/automatic integrated valve, providing high control accuracy and reliability. In the event of an electrical fault, the equipment can still continue to operate in an emergency state by operating the handle.

(5) Proportional Control, Adjustable Process Ratio: During automatic loading of the heavy ammonium phosphate (HAP) oil tanker, only the loading speed needs to be set. The system automatically matches all participating process equipment according to the set loading speed. Through a PID closed-loop control system, it automatically delivers materials in precise proportions, truly achieving one-button start loading. The entire loading process is convenient and reliable. Simultaneously, the process ratio can be adjusted through simple operation on the control interface according to blasting needs, meeting the production requirements of different explosives.

(6) Multiple Protections, Safe and Reliable: The HAP oil tanker does not contain finished explosives, ensuring the entire operation is safe and reliable. Only non-explosive semi-finished products need to be stored within the user's site, eliminating the need to store explosives, reducing storage costs and risks.

Advanced detection instruments such as electromagnetic flowmeters, capacitive level gauges, high-performance speed sensors, temperature sensors, and pressure sensors are used to accurately collect real-time data on the HAP oil tanker's transfer hopper level, sensitizer flow rate, accelerator flow rate, water ring flow rate, diesel flow rate, latex pressure and temperature, hydraulic oil temperature, and other operating information, feeding it back to the system. The system features multiple safety interlocks protecting against low and high material levels in the transfer hopper, as well as interruptions in the flow of latex, sensitizer, accelerator, water ring, and diesel fuel. It also provides protection against latex pressure, latex temperature, hydraulic oil temperature, and operating time. These multiple protection devices ensure the normal operation and safety of the equipment. Furthermore, it has a function for calculating remaining raw materials, effectively guaranteeing the safety of equipment operation and preventing material flow interruptions in the production system. The top of the tank is equipped with 800mm high pneumatically controlled lifting safety guardrails on both sides, along with non-slip perforated footboards, ensuring the safety of personnel working on the top of the tank.

• Unique Water Ring Drag Reduction: A specially designed water ring structure is installed between the charging screw pump (product pump) and the hose, enabling long-distance transport of high-viscosity latex matrix under water ring lubrication. At a transport pressure of 0.5–0.8 MPa, the transport distance of the latex matrix can reach over 80m. Water ring drag reduction conveying technology can effectively reduce the conveying pressure under the same pipe diameter and flow rate, thereby realizing long-distance conveying of latex matrix. For blast holes that are difficult for vehicles to approach, the charging hose can be dragged to the vicinity of the blast hole for filling, thereby realizing multi-directional blast hole filling. Its external structure is as follows:

• Static mixing and rapid sensitization technology An advanced static mixer is installed at the front end of the charging hose. This mixer can not only fully mix the latex matrix, sensitizer and accelerator, but also effectively improve the viscosity of the emulsion explosive after mixing through its shearing action on the latex matrix, which significantly improves the blasting effect of the explosive. By adopting the static sensitization process technology, the latex matrix, sensitizer and accelerator are fully mixed through the static disperser and then injected into the blast hole. According to the ambient temperature and the temperature of the latex matrix, the amount or concentration of the accelerator can be adjusted to meet the rapid sensitization under different temperature conditions, such as 70℃ matrix, normal temperature matrix, and low temperature conditions in winter. After the latex matrix is loaded into the blast hole, it completes foaming in about 10 minutes and forms an emulsion explosive with initiation sensitivity.

(9) Diesel Injection and High-Efficiency Spiral Mixing and Conveying Technology

In the production of ammonium nitrate (AM) explosives, pumpable heavy ammonium nitrate (HAM) explosives, and spiral-conveyed HAM explosives, a combination of diesel injection and high-efficiency spiral mixing and conveying technology was applied. A unique diesel injection device was installed at the end of the diesel conveying line. Before the diesel was injected into the spiral and mixed with porous granular ammonium nitrate, it underwent pressurized injection treatment. After passing through the diesel injection device, the diesel formed an annular oil mist, which was evenly sprayed inside the spiral. After passing through the diesel injection device, the contact area between the diesel and the porous granular ammonium nitrate increased by 5 to 10 times, significantly improving the mixing uniformity of the two.

(10) Spiral Mixing and Conveying Technology

The mixing spiral adopted a broken-tooth progressive (variable pitch) spiral mixing and conveying technology. The spiral was made of integral stainless steel pipe, which caused axial and radial mixing to occur when the material passed through the mixing spiral, forming a composite mixture and improving the mixing effect of the material. The combination of diesel injection and high-efficiency spiral mixing and conveying technology significantly improved the mixing effect and conveying efficiency of the material, and improved the overall performance of the mixed explosives.

(11) PLC Centralized Control and Remote Operation: The cab control system is equipped with an LED vehicle-mounted display screen. The automatic control functions required for each stage of the loading system are centrally controlled by a PLC, allowing operators to complete normal production operations from the cab. One-click matching is achieved according to blasting requirements: Based on the required type of explosive to be loaded, the operator selects the desired explosive type on the control system interface with a single click to complete the operation. A user-friendly human-machine interface is used, along with a high-performance remote control device. Operators can easily complete functions such as loading, cleaning, and data uploading, and can control the lifting and rotation of the auger, reducing the labor intensity of operators and lowering operating costs.

(12) High level of informatization and seamless integration of charging and blasting: The charging operation interface is user-friendly and features displays for matrix temperature, hydraulic oil temperature, sensitizer flow rate, accelerator flow rate, diesel flow rate, water ring flow rate, matrix transfer pump (matrix pump) delivery pressure, and charging screw pump (product pump) delivery pressure. During the pre-set single-hole charging process, the system automatically records, stores, uploads, and prints the parameters of the filled borehole network, including the number of holes, batch charging amount, cumulative charging amount, and hole depth, facilitating blasting operations statistics for blasting personnel. Data can be uploaded wirelessly with a single click.

(13) Unique water-air cleaning system: The heavy ammonium phosphate (HAP) oil truck is equipped with a dual-path water and air cleaning system to clean the delivery pipelines after charging, preparing them for the next charging operation. The vehicle has pre-installed compressed air connection ports (G1/2″) at the latex pipeline, sensitizer pipeline, accelerator pipeline, diesel pipeline, and water ring pipeline. After the system is cleaned with water, the onboard compressed air can be used to clean the pipelines. This prevents the pipelines from freezing and cracking in extreme low-temperature environments. The water and air dual-path cleaning system can clean both the charging screw pump (product pump) and the transfer pump (matrix pump). Simply connect the water pump outlet pipeline to the quick connector and start the charging screw pump (product pump) and transfer pump (matrix pump) to effectively clean the charging screw pump (product pump) and pipeline system.

(14) Strong chassis adaptability and low maintenance cost The heavy ammonium oil truck is equipped with the latest National VI automobile chassis, which has the advantages of sufficient power, strong adaptability, and low fuel consumption. It can adapt to the harsh conditions of mining roads such as muddy, rugged, winding, and slippery roads. The vehicle's maximum climbing ability is 35%, and the minimum turning radius is 11m.
