STORAGE SILOS
& HOPPERS
Custom-engineered stainless-steel storage systems for powders and granules. The twin-silo arrangement combines closed filling, filtered venting, inventory monitoring, flow activation and selected vacuum discharge to downstream process equipment.
HOW THE STORAGE SYSTEM WORKS
FILL
Receive powder from pneumatic. mechanical or gravity feed
VENT
Release displaced air through a correctly sized filter.
MONITOR
Track level and inventory using switches or load cells.
STORE
Maintain closed. protected and traceable product holding.
MOBILIZE
Activate the cone to prevent bridging or ratholing.
TRANSFER
Open the selected outlet and draw through the suction bowl
APPLICATION FIT & ENGINEERING VALUE
RIGHT APPLICATION
Pharmaceutical and nutraceutical
Closed SS storage for powders, excipients, premixes and granules with hygienic access and controlled transfer.
Food and specialty ingredients
Protected storage for flour, starch, sugar, additives and free-flowing or moderately cohesive ingredients.
Chemical and polymer processing
Application-specific construction for pigments, additives, resins, minerals and engineered bulk solids.
DESIGN VALUE
Stable downstream feeding
Bin activation and a correctly selected outlet promote repeatable draw-off to conveying or dosing equipment.
Visible inventory
Level devices and optional load cells support replenishment planning, batch accountability and low-level protection.
Flexible duty arrangement
Twin silos can serve duty/standby operation, product segregation or controlled changeover between sources.
CONSTRUCTION & CONFIGURATION OPTIONS
PRODUCT-CONTACT CONSTRUCTION
SS304 or SS316L with application-specific internal finish, weld treatmentand gasket selection.
STORAGE GEOMETRY
Cylindrical shell with engineered cone, access cover, vent connection and structural supports.
INVENTORY MEASUREMENT
High, low and high-high level switches; optional load-cell based continuous mass indication.
FLOW PROMOTION
Bin activator, vibration, air pads or other flow aid selected from actual powder flow behaviour.
OUTLET AND TRANSFER
Isolation valve, suction bowl, rotary valve, screw feeder or gravity outlet to suit downstream duty.
AUTOMATION AND PROTECTION
Fillpermissive, high-high trip, outlet sequencing filter monitoring, earthing and PLC integration.
CONTROLLED STORAGE AND VACUUM DISCHARGE
The approved twin-silo concept controls filling, venting, inventory and product flow. During discharge, only the selected silo is enabled: its bin activator mobilizes the powder, the isolation valve opens, and the suction bowl feeds the common vacuum conveying line.
CONTROLLED OPERATING SEQUENCE
FILL
Prove capacity available, filter ready and outlet closed.
VENT
Filter displaced and conveying air without dust escape
MONITOR
Track high, low and optional continuous mass signals.
SELECT
Choose one sião; keep the standby outlet isolated.
ACTIVATE
Start flow aid only under an approved discharge demand.
TRANSFER
Open outlet and convey through the common suction line.
CONTROL, SAFETY & MAINTENANCE
Fill protection
High-high level stops incoming product; vent filter readiness is a filling permissive.
Selected-path interlock
The duty silo valve and flow aid operate only when the downstream receiver and vacuum are ready.
Filter condition
Differential pressure or maintenance indication helps preserve venting capacity and containment.
Empty protection
Low-level or low-weight logic prevents extended empty conveying and supports changeover.
Structural safety
Maximum product, tare, accessory, dynamic and site loads are included in final support design.
Hygiene and access
Cleanable connections, inspection access, isolation, earthing and safe maintenance provisions are defined.
PRELIMINARY STORAGE SIZING GUIDE
This page supports early capacity screening only. Final usable volume, cone geometry, outlet, venting, structure, flow aid and transfer system require
confirmed powder tests, operating conditions and site loads.

CORE PRELIMINARY CALCULATIONS
1. REQUIRED GROSS VOLUME
Vgross [m3] = Required storage mass [kg]/ (Loose bulk density [kg/m3] x usable fill fraction)
2. STORED PRODUCT MASS
Mass [kg] = Usable product volume [m3] x loose bulk density [kg/m3]
3. STORAGE AUTONOMY
Autonomy [h] = Available product mass [kg]/ average downstream consumption [kg/h]
4. MAXIMUM SUPPORT LOAD
Design basis includes silo tare + maximum product + accessories + piping + dynamic and environmental loads.
FINAL SELECTION CHECKS
Powder flow
Cohesion, wall friction, segregation, flooding, bridging and ratholing determine cone, outlet and flow aid.
Venting
Filter duty must cover displaced air plus any conveying-air return without overpressure or dust emission.
Storage quality
Residence time, moisture pickup, temperature, aeration and cleaning define protection and finish.
Transfer duty
Required rate, line size, lift, bends, receiver and vacuum source determine the suction arrangement.
Structure and site
Indoor/outdoor, access, wind, seismic, platform, maintenance and allowable floor loads are verified.
Safety and controls
Area classification, earthing, explosion protection, interlocks and safe isolation are application-specific.
FINAL ENGINEERING CHECK
Confirm bin drawing and mass
Define CV and sampling
