2.1 Product Introduction
Batch mixing trailer is mainly composed of trailer chassis, power system, batch mixing tank, manifold system, electrical system, centrifugal pump, hydraulic system, gas system, control system and so on.
Batch trailer is mainly used for batch mixing equipment for cementing operations in desert and land oil fields, and can prepare oilfield cementing slurry with high efficiency and high quality by mixing with agitator.
The equipment takes into account the actual working conditions of the oilfield to form a new product that can be both continuous and batch mixed.
The equipment can meet several working conditions.
Continuous mixing: The mixing slurry can be pumped directly from the mixing tank through the transfer pump to the suction end of the large pump to complete the operation.
Batch mixing: The slurry continuously mixed from the mixing tank passes through two batches of mixing tanks successively to achieve batch mixing storage and continuous cementing operation.

6. Electrical System
The power supply of the electronic control system is provided by the battery and the generator of the engine, providing power for instruments, engine start, stop, lighting, etc. The lighting device is easy to operate at night and observe and measure the liquid level inside the tank.
7. Mixing System and Manifold System
The mixing system is a crucial core component of batch mixing equipment, primarily consisting of a centrifugal pump, jet manifold, mixing tank, mixing pipeline, flow meter, densitometer, simple mixer, and ash supply manifold.
A pressure gauge is installed on the injection manifold to monitor injection pressure.
The suction inlet of the circulation pump is positioned lower than the tank and main pipelines to facilitate the discharge of residual liquid from the tank and pipelines, ensuring a rational pipeline layout and good suction performance.
The injection pump suction inlet is equipped with a 4” connector (FIG206 union type) for connecting to clean water.
The suction manifold at the bottom of the front batch mixing tank (near the engine) is slightly higher than that of the rear batch mixing tank. Viewed from the side of the skid, the entire tank bottom suction manifold is higher at the front and lower at the back, facilitating cleaning and drainage of the entire vehicle. A 4” drain port (FIG206 union head assembly) is located at the lowest point of the rear batch mixing tank manifold.
All rigid pipelines are rationally laid out with smooth transition angles. Connections between pipelines are kept as short as possible and use clamps for easy disassembly and cleaning. The pipeline routing is designed with a certain angle to ensure good suction and discharge performance.
For convenient post-operation cleaning, a 10-meter cleaning pipeline with a high-pressure nozzle is designed into the injection pipeline.
