Another outstanding success @ Hillhead 2014 . . . .

With fine weather throughout, the turnout at this year’s Hillhead expo was extremely high with many decision makers present. We would like to thank all visitors to our stand and for the high volume of enquiries received, across a wide variety of products on show. A substantial order was forthcoming at the show for 24 of our heavy duty filters ( without the union jack livery ) lending weight to sustainable growth in the UK market. Other products that took visitors interest were the SN8000 Outloader & the UK debut showing of the innovative Rotary B'Fly valve but leading the way in interest & enquires was the shaftless screw stand, a relatively new addition to our ever popular range of shafted screw conveyors.

Extract for those who couldn’t attend this year’s expo.

Front L/H show working demo of various level detection devices, including the ever popular semi continuous level.

Front centre, extracts from our filter family with the Maxair 24m2 centre stage ( an OEM favourite ) & front R/H showing the heavy duty SN filter

In the background are samples from our standard & rotary butterfly series & samples from our shafted screw range. Also, by the steps, was the UK debut of the all new quick fit flexible sleeve - FlexAtex™.

Front R/H show the working model of the SN8000 series Outloader with integral filter.

Back centre shows samples from the shaftless screw range with various liner options – the most popular exhibit on the stand

All @ SN Engineering gratefully acknowledge the time clients, old & new, that took time out of their busy schedules to visit Hillhead, and in particular our stand and we look forward to being of service in the near future.

We cordially invite all to re-convene at the same location @ Hillhead 2016, we look forward to it . . . .

New CaCO³ processing plant comes on line: 

Bulk silos 2 @ ~2500Te each & 1 @ 500Te capacity

        October saw the culmination of a year’s work by SN Engineering, UK based bulk materials handling specialists, with the completion of the 1st phase of commissioning of a new carbonate processing plant.

Calcium carbonate, or CaCO3, comprises more than 4% of the earth’s crust and is found throughout the world. It’s most common natural forms are chalk, limestone, and marble, produced by the sedimentation of the shells of small fossilised snails, shellfish, and coral over millions of years. Although all three forms are identical in chemical terms, they differ in many other respects, including purity, whiteness, thickness and homogeneity. Calcium carbonate is one of the most useful and versatile materials known to man.

Some typical uses for CaCO3            

Paper, Plastics, Paints, and Coatings:

Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler – and due to its special white colour - as a coating pigment. In the paper industry it is valued worldwide for its high brightness and light scattering characteristics, and is used as an inexpensive filler to make bright opaque paper. Filler is used at the wet-end of paper making machines, and calcium carbonate
filler allows for the paper to be bright and smooth. As an extender, calcium carbonate can represent as much as 30% by weight in paints. Calcium carbonate also is used widely as a filler in adhesives, and sealants.

Personal Health and Food Production:

Calcium carbonate is used widely as an effective dietary calcium supplement, antacid, phosphate binder, or base material for medicinal tablets. It is also found on many grocery store shelves in products such as baking powder, toothpaste, dry-mix dessert mixes, dough, and wine. Calcium carbonate is the active ingredient in agricultural lime, and is used in animal feed. Calcium carbonate also benefits the environment through water and waste treatment.

SNE’s brief was to design a facility that would accept & store the raw bulk material before being conveyed to the grinding & classification process.

Following processing, the sub 75µm finished product was to be conveyed and stored in a pair of 2600m³ ( 12.5mØ ) bulk storage silos. The client then required a high capacity, dust free, out loading facility from the bulk storage silos to road vehicles for onward movement to their client.

Other major considerations was that of logistics – all this was to take place some 2000 miles from HQ @ Gloucester – and would involve more than 20 x 40ft road & sea going containers. 

Rising to the challenge, SNE completed the task- from initial conception, to design thru’ manufacture & delivery to site & finally supervision of installation & 1st commissioning in just 12 months.

Fed via ground receiving hopper, the raw material is conveyed via a series of belt conveyors, and thru’ an intermediary crusher which reduces the rock down to ~50mm, and then onward to a bucket elevator which in turn feeds into a specially designed ~500m³ x 7.6Ø storage silo. The silo has been designed with a larger than normal outlet, to eliminate possible bridging and has the added advantage of 3No vibrators for aiding discharge when required.

Once the CC is processed, the GCC is then pneumatically conveyed via a 168Ø conveying line to the top of the 12.5Ø  x 30m high silos; at which point it is diverted to either of the preselected silos. A dense phase system was selected for this task, and although new to the client ( traditionally they had used dilute phase ), the system has proved successful in conveying the product with minimum velocity & quick cycle times – typically 45 seconds to convey 2.2Te over a total conveying line of ~75m.

Complete feed back to the client’s plant room for both the compressors / dryer & the conveying system is maintained via Profibus interfacing. 

Each silo is equipped with a high capacity, fan assisted, dust plant to ensure all introduced dust laden air is 
safely managed with only pre-filtered air being released to atmosphere. With each of these silos having a working capacity of ~2500Te stock inventory is maintained via a dual system of weigh indication & continuous level devices giving a continuous feedback to the client plant room via 4-20mA signalling.

To ensure the 2500Te of stored product discharges freely, the whole of the silo cones have been fitted out with air slides & externally piped to 1 of 3 independent ring mains, thus ensuring any area within the cone can be aerated as and when required.

In addition, each silo aeration system is being fed by its own dedicated low pressure, high volume blower unit. Each of these blowers is enclosed within their own acoustic cabinet to further reduce on noise pollution.

Once the 2600m³ silos have received the processed material, the product is discharged via 1 of 2 407Ø high capacity, heavy duty designed screw conveyors which in turn discharge, via a SN7000 series dust free loading bellows, into road tankers for onward shipment to client.

SP silos range enhanced . . . . .

Bulk Silo skirted 70m3 capacity          SN Engineering saw the evolution of the SP- 3.5mØ series of silos as a natural progression into offering clients the flexibility they desired. Until recently the ever popular range of 3.5Ø silos—35 to 125m³ capacities, revolved around the standard 4 legged construction design.

Following thru’ on a specific need from an existing client that utilised these silo’s and then externally clad-in the bottom section—for
weather protection of their equipment installed to discharge & convey the silos contents— raised the obvious question , well seems obvious now, as to whether these units could be adapted within their design to include for skirts.

In consultation with the design & manufacturing engineers a solution was found that not only looks aesthetically pleasing but also gave a lower overall capital cost. With the benefit of reducing site labour time & cost when compared to previously clad options.

Rolled out during the 1st half of 2012 the initial client has now standardised on this option and has reported a very good reception from their clients.

Having now proved the design & concept the units have subsequently been offered out to other clients with a very positive uptake and are forecast to fast become the leading option & preferred choice within the 3.5mØ series.

Initial plans are to possibly roll out this option to the next series size within the family and some market research is currently underway for evaluation of clients initial thoughts—the feedback would currently suggest that this option would be well received—watch this space for regular updates . . . . .
