- Adoption of spiral conveyor, high-efficient and maintenance-free.
The powder measuring and supplying system consists of the silos, spiral conveyor and powder measuring devices. The
powders (cement, coal dust, etc.) are filled into the storage silo through bulk cement tank car. The silo top is provided with
dust collector, which feature good dust collection and easy maintenance. In addition, the silo top is provided with pressure
relief valve and material level indicator. The automatic opening of relief valves can prevent too high an in-silo pressure.
The level indicators can produce the actual materials level. The silo bottom cone is provided with fluidisation pads so as
to break through arched powder. The silo bottom is provided with hand-operated butterfly valves to facilitate maintenance
of the silos and spiral conveyor. When it is necessary to feed powder into the mixer, the powder from the silo is conveyed
with spiral conveyor into the powder measuring devices (cement measuring device, coal dust measuring device) for
measuring purpose. The spiral conveyor would not stop feeding until measuring requirements are met.
- With pressure relief guards
- Silo top with material level indicators
- Silo top with dust collectors
- Silo bottom with fluidisation pads
The silo is a container for storing cement, coal dust and the like similar kind of powder. Its upper portion is provided with material
level indicators and its lower portion with signal lights. When the silo has been fully filled, signal lights in the control room and on the
silo lower portion will be on, warning simultaneously. At this time, powder must be stopped conveying immediately. The silo upper
portion is provided with dust collectors to prevent dusts from entering the atmosphere, causing environment pollution. The silo upper
portion is also provided with pressure relief guards. When the cement tank car fills cement into the silo and causes excessive pressure
in silo, the guards will open automatically for pressure relief to avoid accidents. Prolonged operation of dust collectors will lead to
decrease filtering efficiency of filter cores. And exhausting capacity will be decreased too. This will cause excessive pressure in
silo during cement conveyance, leading to relief guards start-up. Therefore dust collectors must be checked and cleaned at a regular
interval to change filter cores just in case.
-Cleaning the filter cores at dust collectors can be on the responsibility of a designated person, who must start up the vibrating motor
after charge completion. The running duration of the vibrating motor must not be longer than one minute.
-Each charge duration must not be too long. No longer than one hour is preferable.
-Once half a year filter cores must be checked for dirty materials. The filter core must be taken down and cleaned if too dirty.
The silo bottom is provided with fluidisation pads. The air pressure for arch breaking is controlled at 0.1~0.3Mpa. The manual
butterfly valve is provided between the silo bottom and spiral conveyor to facilitate maintenance of the silo and spiral conveyor.
2 .Spiral conveyor
- Variable pitch-designed blades with high-efficient conveyance
- Specially designed for powder conveyance
- Maintenance-free middle supports
The spiral conveyor is the equipment to convey the powder from the silo onto the powder scale by means of continuous spiral
3 Powder (cement, coal dusts) measuring device
- sensors to ensure measuring accuracy
- Large diameter butterfly valves with high efficient charging
- Compensation of unbalanced sensors
After the powder hopper (cement hopper, coal dust hopper) has contacted the sensor via connection seat, sensor signals will be output and amplified and compared with pre-set values. When the powder has reached pre-set values, the spiral conveyor will stop powder feed. When the mixer requires powder feed, the butterfly valve will open and powder will be discharged directly into the mixing drum of the mixer. After discharge completion, the powder scale will start at once the next measuring operation, thus making full use of the mixing time and reducing the mixing period. The powder scale hopper is provided with two powder inlets. The powder from different silos can be placed onto the scale via start-up of different powder spiral conveyors. The cement scale hopper and coal dust scale hopper are both provided with vibrators to facilitate powder into the mixer. For details, refer to 4.10 Electronic Scale
