Features

MR Continuous Mix Asphalt Plant is continuous hot mix asphalt plant. It's designed for portability, durability and reliability. MR hot mix asphalt plant is a cost-effective product which has characteristics of modular design, compact structure, fast set up, easy relocation, less power consumption and high fuel energy efficiency. 

High Precision IAggregates Dosing 

When collecting ingredients, the aggregates of different particle sizes that need to be mixed are respectively loaded into different batching hoppers by using a loader, and belt conveyors are arranged under each batching hopper, and the belt conveyor is driven by a frequency conversion speed regulating motor. The ingredients are mixed according to the mixing ratio of the construction technology; the matched materials are dropped on the horizontal aggregate belt conveyor, which is transported through the filter screen to the inclined belt conveyor.

Counter-flow Dryer

The drum counter-flow rotary drying heating method is provided with a spiral rewinding blade and a feeding blade in the cylinder body, and different shapes of reversing blades are installed in different regions, and the drum cylinder body has an inclination angle of about 3.5-4 degrees, and the outer layer has 40cm of thermal insulation rock wool prevents heat loss.

  1. Fully dedicated to aggregates drying and heating. It operates in a counterflow system, in which the heat is applied gradually over the aggregates, respecting the physical laws for moisture extraction, ensuring high productivity and low fuel consumption.
  2. Designed using advanced computerized simulation systems, it has fins designed to efficiently meet all the steps of the drying and heating stage with maximum efficiency, ensuring complete elimination of moisture, correct temperature and high throughput
  3. Automatic control of the dryer spin speed results in the maximum heat exchange between the aggregates and fuel gases
  4. Intelligent exhaust system that ensures perfect combustion regardless of the production rate

Air Burner

The fuel burner is controlled by a single-chip microcomputer program. Simply press the “Start” button to start the oil pump, auto-ignition, flameout alarm, automatic temperature control and display. The fuel can be automatically adjusted according to the required furnace temperature. . It is also equipped with a manual function to ensure the normal operation of the burner through a manual system when the system fails.

Twin-shaft Reverse Pugmill Mixer 

The mixing machine adopts the horizontal double-shaft paddle type spiral stirring method, the stirring blade, the stirring arm and the lining plate are all made of chrome-molybdenum alloy wear-resistant cast iron, and the stirring arm is made of cast steel material. It has strong corrosion resistance and wear resistance, which greatly prolongs its service life.
