The Parts & Features

Cold Feeder System

std_coldfeederEvery hopper is equipped with belt convayor controlled by frequency convertors. The primary recipe can be delicate and the energy consumption is minimized. Bin-wall vibrators are mounted on wall of sand hoppers to ensure the materials feeding. A grill is to prevent oversize materials getting into the dryer drum. The feeder bin system is mounted with pulling switch for personnal safety.

Dry Drum System

std_drydrumThe drum body is designed for high efficiency and energy saving. The fully-automatic burner from Italy can have diesel, heavy oil and gas as fuel options.The steel plates of dryer blades are made of HARDOX400 from Sweden, which has high wear resistant and heat resistant.

Filler Silo

std_fillersiloStand alone for imported filler silo and recovered filler silo respectively are available. Stack-up type of two silos are also available. The fluidifying air system fixed in the cone section is made of silicon dryer, adjusting pressure valve, solenoid and air ejector, to avoid humping in the bin cone. The blowing time and the intermission time can be adjusted to ensure equable and continuous filler feeding.


std_mixingtowerThe arms are symmetrically crossed to ensure high-speed, effective and well mix quality. The liner boards, paddles and arms are made of high chromium and high molybdenum materials. They are easy to be adjusted and changed.

Vibrating Screen

std_screenDouble vibrating motors (for DG4000 and above is double horizontal shafts) and compulsory vibrating screen, the passing rate reaches 95%. 48-hour non-stop inspection with CSI digital vibrating tester (USA standard) is conducted before ex-works for every operating vibrating screen.

Weighing System

std_weighingBoth the aggregate and filler scales are weighing aggregate and filler in an accumulative method. The weighing hopper is a container with hot oil cladding to preserve heat and ensure the weighing accuracy. The weighing system will reckon the portion of aggregates against that of the asphalt and display the temperature of asphalt on the computer in the control cabin.

Bag Filtering House

std_dustcollectA special designed on Pre-separator is simple in structure and effective in separating the bigger size particles from the emission. The filter bags are made of DUPONT NOMEX material with high temperature resistant. The emission can be less than 20 mg/Nm³. Temperature sensors are installed to protect the filter bags from over-heated and moisture condensation.

Hot Storage Bin

std_hotstoragebinThe hot storage bin is designed to prevent final mixture from isolation.It is equipped with continuous level indicator, which is connected with acoustic and optical alert. The skip travels along the track driven by the frequency controlling windlass. On the track, there are upper/lower limit switches to ensure skip operates precisely and safely.

Control Room

std_controlsystemFully computerized control panel and HMI back-up system for high reliability. A 120-hour non-stop test is conducted for every control system to ensure problem free before ex-works. Reliable electronic components and PLC are applied to secure the performance of the plant. Remote control system can be setup for remote diagnosing and monitoring.
