Aggregate weighing

A. Hot aggregate bins.

5 discharging doors are installed under hot aggregate bins. Every door is controlled with 2 air-cylinders. Weighing precision is improved through secondary weighing.

B. Weighing hopper

Aggregate is discharged from hot storage bins to weighing hopper. Weighing hopper is hanged to steel frame through tensile sensors, which carry signals to control system.

The emptying door of weighing hopper is promoted by air-cylinders. Door shafts need no lubrication, but check them every 6 months for abrasion and replace them if necessary.

C. Dustproof cover

There is a dustproof cover between weighing hopper, hot storage bins and mixer. Joint has a soft airproof part. The weighing hopper should not bump with cover.

There is a exhaust pipe at the cover, which allows air to flow freely. When weighing hopper discharges aggregate to mixer, the inner air will expel, so as to avoid hopper to shake. Check this exhaust pipe for block every 3 months.

D. Sampling window

Open the sampling window at upper cover joint, get sample from each hot bin.

E. Tensile sensor

3 tensile sensors hang the weighing hopper. These sensors need no maintenance and adjustment, but notice the following items to guarantee its life.

When carrying on weld near weighing hopper weigh barrel, earth the barrel to avoid current enters sensor.

When carrying on maintenance, and have to remove weigh hopper or influence sensor, ensure reinstallation equals to former standard, and on one level, screw down all locknuts

Check weigh hopper for fine stone or dunghill that influence hopper moving.
