Complete process for handling powders and bulk materials in the chemical industry
SYVRAC designs complete installations for handling powders and bulk materials in the chemical industry. Our design office integrates internal equipment and partners to create turnkey processes adapted to the safety, quality and productivity constraints of chemical sites worldwide.
- Design office specialising in powder and bulk processes for all chemical fields
- Integration of SYVRAC and partner powder storage and handling equipment for complete solutions
- Turnkey management of projects in regulated environments (ATEX, SEVESO, OEB, etc.)
- Expertise in sensitive, abrasive, toxic or explosive products
Description
SYVRAC provides the chemical industry with cutting-edge expertise in powder and bulk processes, covering the entire solid raw material processing chain. Our highly experienced in-house design office tailors each project to the specific characteristics of each product, safety requirements (ATEX, OEB, SEVESO, etc.) and productivity challenges.
We design and build complete lines incorporating:
- Sealed big bag emptying
- Controlled atmosphere truck unloading
- Secure storage silos with explosion vents
- Confined or nitrogen-based pneumatic or mechanical transfer
- Multi-component weight dosing
- Homogeneous mixing, even for reactive products
- Controlled grinding/micronisation
- Control sieving
- Semi-automatic packaging in big bags or sacks
- Centralised supervision and complete traceability
Commonly handled products:
Our experience has led us to work with all types of chemical powders. Here are some of the compounds we have already processed using our Syvrac processes:
pigments, silica, carbon black, mineral fillers, waxes, resins, plastic powders, PVC granules, technical polymers, metal oxides, pharmaceuticals, catalysts, chemical fertilisers, abrasive powders, cosmetic additives, detergent powders, filtration agents, ion exchange resin beads, coating powders, silica fumes, industrial starches, technical food powders.
Our teams integrate SYVRAC equipment and complementary technologies from our partners (fine grinding, drying, high-precision screening, decontamination, CIP, etc.) to meet all your chemical powder deconditioning, handling, transfer and bulk reconditioning needs.

Options
Our comprehensive bulk and powder handling process for the chemical industry is standardised, but options allow us to tailor it to your needs and requirements.
Operator containment
Automated CIP
Enhanced ATEX safety
Centralised dust filtration
1 • Receipt of chemical raw materials
Solid bulk products are received and unloaded via big bag emptying stations equipped with containment systems to protect operators (glove box, sealed connection head) or via tank lorry unloading, sometimes in a neutral atmosphere under nitrogen. These stations guarantee total safety in ATEX or OEB environments. High-efficiency filtration and extraction systems keep the area clean and contained. Truck unloading can be combined with an automated sampling bench to immediately check incoming batches.
2 • Secure storage for sensitive products
SYVRAC, an expert in powder storage, offers a wide range of silos adapted to chemical constraints: coated steel silos, 316L stainless steel, or polyester resin for chemical resistance. Each silo can be equipped with pressure/temperature monitoring, ATEX instruments, and breakaway devices (discs, vents, valves). Our design office takes into account all safety constraints as well as product constraints such as density, abrasiveness, or reactivity, with options for fluidisation or internal agitation to ensure product flow.
3 • Pneumatic/mechanical confined transfer
SYVRAC develops and installs all types of confined transfer systems: pneumatic (dense or dilute phase, suction or pressure) or mechanical (screws, elevators, vibrating conveyors). For explosive or toxic products, the entire process can be inerted with nitrogen, and each line is equipped with safety systems, ATEX sensors and safety devices. Manufacturing is suitable for all sectors, including mirror-polished, micro-blasted stainless steel or water-polished finishes.
4 • Secure packaging in bags, big bags or drums
SYVRAC integrates all types of packaging stations. These systems are designed to guarantee cleanliness, operator safety and traceability. Syvrac offers systems for bagging, filling big bags or packaging drums. Filling can be carried out in a confined manner. The equipment can integrate weighing, labelling, inerting, sealing and sampling.
5 • Types of chemical process lines produced
SYVRAC designs and installs complete turnkey lines for the chemical and fine chemicals industries, integrating its own equipment and that of specialised partners. Here are some examples of lines produced:
- Secure transfer of fumed silica to a mixer under inert atmosphere with packaging in sealed big bags – ATEX Zone 21
- Emptying of pigment big bags and weight dosing in multi-component formulation, line equipped with metal detectors, safety sieves and CIP cleaning
- Controlled micronisation of mineral fillers with calibrated screening and repackaging in bags via automatic bagging machine with operator containment
- Grinding of technical plastic powders and granulation, including confined mechanical transfer and storage in HDPE resin silos with internal fluidisation
- Unloading of carbon black tanker trucks with centralised filtration, extraction to buffer hopper and filling into closed metal drums
- Chemical fertiliser formulation process including paddle mixers, high-precision dosing screws and robotic palletising
- Sensitive catalyst transfer line with secure transfer lock, ATEX instrumentation and batch tracking integrated into the MES system
Each line is designed with regulatory constraints in mind and delivered with full qualification, technical documentation and operator training.
