Product Description

What is rubber asphalt/bitumen

Crumb rubber modified asphalt/bitumen, abbreviated as CRMA or CRMB, is a product that meets the relevant technical index requirements by mixing Crumb rubber and asphalt (sometime with a additives) in a certain proportion using special equipment. It is also called asphalt rubber, Crumb rubber modified asphalt/bitumen.

What is asphalt rubber blending plant? 

The asphalt rubber blending plant is a kind of equipment that mixes  Crumb rubber and high-temperature asphalt. Each country has different names, such as rubber asphalt plant, crumble rubber asphalt/bitumen plant or asphalt rubber blending equipment.

Main composition
It consists of asphalt rapid heating part, rubber powder elevator, blending tank, reaction development tank, control system, etc.

What supporting equipment is needed to run a Crumb rubber modified asphalt plant?

Thermal oil boiler, Provide heat source to heat bitumen。 
Bitumen tank ,Storing and heating raw bitumen
CRMB tank,Development and storage of CRMB。

Production Process

11

1. The bitumen is heated by transfer oil through a heat exchanger to 195-210°C.
2. The bitumen enter the mixing tank after passing through the flow meter.
3. After PLC calculates the lifting speed of Crumb rubber based on the flow rate and formula of bitumen, it starts the hoist and adds Crumb rubber at the predetermined speed.
4. The high-temperature bitumen and Crumb rubber are mixed evenly in the mixing tank through high-speed stirring.
5. The mixture of asphalt and rubber powder passes through the pump and enters the development tank.
6. After the mixture is grown in the development  tank for 45 minutes, the test is carried out.

Advantage

1. The Crumb rubber is added using electronic weight-reducing weighing and spiral frequency conversion speed regulation for feeding.
2. The bitumen supply is measured by a variable frequency pump speed controlled flow meter.
3. Bitumen heating uses a large-capacity heat exchanger and electronic temperature control to adapt to the ambient temperatures in different regions.
4. Both the host machine and the reactor unit adopt container structure, which is convenient for supporting, high productivity and easy to move.
5. Special rubber asphalt pump greatly improves the reliability of the plant.
6. PLC + program controller realizes manual/automatic control, which is convenient, safe and reliable, and the human-machine dialogue interface makes the control more humane;
7. The use of international brand electrical components such as Siemens and Schneider greatly improves versatility and reliability.
