Mixing System

• The main mixer of the 120 concrete batching plant adopts a JS2000 twin‑shaft compulsory mixer, featuring strong mixing capacity, excellent mixing uniformity, high production efficiency and reliable performance.
• It achieves ideal mixing results for dry-hard, plastic and various mix‑ratio concrete. The mixer top cover is equipped with a water spray pipe, inspection door, observation door and feeding device.
• The feeding device includes inlets for cement, fly ash and aggregates, as well as a water inlet device. To increase the impact of water on the main shaft, a pipeline pump is installed on the mixer cover to prevent material from sticking to the shaft.

Aggregate Batching and Conveying Section

• The aggregate batching and conveying section consists of an aggregate batching machine and an inclined belt conveyor.
• The process flow is: aggregate yard → storage bin → weighing hopper → horizontal belt conveyor → inclined belt conveyor.

1. Aggregate Batching Machine

• The aggregate batching machine is equipped with four aggregate bins, suitable for grading up to four types of aggregates.
• Aggregate bins feed materials to the weighing hopper, with precise weighing controlled by a microcomputer weighing controller. It can perform weighing setting, zero reset, weight compensation, output control signals and other functions.

• 2. Inclined Belt Conveyor

• The inclined belt conveyor is mainly composed of conveyor belt, transmission device, idlers, cleaning device, frame, escalator and so on.

• After the weighed aggregates are discharged by the horizontal belt conveyor, they are fed into the intermediate storage hopper by the inclined belt conveyor.

• Overhaul passages are arranged on both sides of the inclined belt conveyor, and chutes are installed at the bottom to prevent material from falling.

• Powder Storage and Conveying System

• The powder storage and conveying system consists of cement silos and screw conveyors.
• The process flow is: powder silo → screw conveyor → powder weighing hopper.

• 1. Cement Silo

• The cement silo is a steel structure, composed of support, cylinder, flap door, top silo dust collector, arch breaking device and feeding pipe.
• Powder is blown into the silo by compressed air through the feeding pipe, and the pressure air inside the silo is discharged through the top silo dust collector.
• Each cement silo is equipped with high and low level indicators to show the empty or full status of the silo.

• 2. Screw Conveyor

• The screw conveyor is a device used to convey powder from silos to the weighing hopper for metering.
• It is mainly composed of power transmission device, screw shaft, pipe body, intermediate support, inlet and outlet pipes, etc.

  It features high conveying efficiency, good sealing performance, no dust pollution, and is sectionally assembled for easy transportation.
