CE conformity for Screw conveyor
For Screw conveyor, the applicable CE scope is determined from intended use, energy sources, safety architecture and target market. The risk assessment, technical file, testing and conformity route must be verified against the actual model.
The transport agentScrew or centerless spiral wrapped over a mile; pipe or U-boat rotation
LocationLayered, sloping or vertical; single or multiple entry-exit arrangements
Protected pointsThe toilet, the exit, the examination lids, the caplin and the mid-bed
Critical failureTightness, excessive torque, breaking of the mile, bed warming and refeeding
Direct response to the scope
CE conformity for Screw conveyor — Define the product boundary first
The rotating helix pushes dust, granules, mud or small pieces into a pipe or U-shaped boat. If the feeding mouth is left open, the arm, cleaning apparatus or bag can be caught in the viaduct; opening the product flow manually in the exit shot gives similar access.
Long or multi-bed conveyors require periodic maintenance of suspension beds, interlocking covers and flanges. Although the opening of the lid is an advantage of manufacturing, screws should not be accessed completely continuously. Excessive torque of the engine during the grip can leave compression energy in the material; feed insulation, screwdriver lock and controlled discharge are applied before the lid is loosened.
When carrying burning dust, the enclosed body does not eliminate the explosive atmosphere; on the contrary, it can create a volume where the dust is trapped. Source temperature, foreign metal, static electricity, bed heating and connected filter-silos are evaluated.
Product profile
Technical features that change the evaluation
The following data shows why even models with the same product name can change the path of conformity.
The transport agentScrew or centerless spiral wrapped over a mile; pipe or U-boat rotation
LocationLayered, sloping or vertical; single or multiple entry-exit arrangements
Protected pointsThe toilet, the exit, the examination lids, the caplin and the mid-bed
Critical failureTightness, excessive torque, breaking of the mile, bed warming and refeeding
Risk architecture
The main dangers to be addressed in the file
The protective, control and verification approach shall be based on the actual product cycle.
Not caught when the lid is opened
The screws are visible under the interim inspection cover.
The energy of resistance
The tight product, the flexible mile and the full feeding tank can move when the lid is opened.
Turn around and don 't jump
The wrong phase or maintenance command can move the product in an unexpected direction, throwing it out of a clear point, confirming the direction control and interface logic.
Heating the bed
Loss of grease or compaction can create a hot surface and fire hazard on the suspended bed.
The dust-chemical-hygiene exposure
Depending on the product being transported, explosive dust, irritating chemical or microbiological residue is formed.
The conditional law matrix
When will the regulation take effect?
A single product name doesn't give the same answer for all models.
| The subject | The situation | Product-based evaluation |
|---|---|---|
| The machine's layout | YES, YES | In Turkey, 2006/42/AT is applied for the propellant; the next national compliance is confirmed on the date of the propellant's first market launch or first service. The engine screw and body are examined together. 2006/42/EC is applied in the EU/EEA, including 19 hob 2027; for propellant conveyors, from 20 hob 2027 (EU) 2023/1230. |
| EMC | IT 'S A MESS . | EMC scope is assessed in terms of the intended environment; driver and communication patterns affect test requirements. |
| LVD | NO , NOT AT ALL . | The LVD is not applied to machinery as a separate directive; electrical safety objectives are met within the scope of machinery legislation. |
| PED | NO , NOT AT ALL . | Standard helenone pressure equipment carrying atmospheric products is not; if the process body is designed under pressure, the result is re-evaluated. |
| ATEX | IT 'S A MESS . | If there is burning dust or steam, the indoor and outdoor zones, mechanical spark, bed temperature and electrical equipment category are taken into account. |
| Food theme | IT 'S A MESS . | If food is transported, contact materials, hygienic design, lubricant, demontability and cleanliness evidence are handled in parallel to the CE process. |
Standard and verification approach
- EN 618: Casting material other than fixed-band conveyors shall be evaluated for safety and EMC requirements in mechanical conveyor equipment.
- EN ISO 12100: It structures product, settlement, cover access, clogging and maintenance behavior throughout the life cycle.
- EN ISO 14120: It supports the principles of mechanical design of boat decks, turtle shelters and access grids.
- EN ISO 14119: It is used to select the lock mechanism on the frequently opened inspection lids and to reduce defeat.
- EN ISO 13849-1 and -2: The cover lock is used to verify the safety functions of over-tork and cross-line stopping.
- EN ISO 14159: It provides an approach to the cleanability and contamination risks of machine design in food or similar hygienic processes.
- EN 60204-1: If applicable to an electrical configuration, it is used in feeding, engine, control and testing; it is not written as an automatic requirement.
Important distinction
CE conformity for Screw conveyor — Product conformity is a separate study.
ISO management system certification does not replace product-specific risk analysis, test evidence and compliance file.
The compliance work plan
In what order will the technical preparation proceed?
Product and task definitions
The material being transported, the length of the beam, the humidity, the combustion capacity, the cleaning and the feeding form are converted into technical input.
Access map
The use of the containment at the normal use of the sink, exit, mid-cap, caplin and bed points is examined.
Mechanical control design
The grille, locked lid, torque monitoring, directional control, insulation and line interlocks are set up according to the risk outcome.
Test and verify
Standing, opening, overloading, reverse direction, smuggling-to-powder and if any, temperature functions are tested with the actual product.
File and instructions
The opening of the shed, cleaning, bed maintenance, product limits and remaining risks are completed with the statement.

Frequently Asked Questions
CE conformity for Screw conveyor — Technical answers about
How do you verify the safety of the heloton entry grid?
The opening of the lattice, the safety distance, the product flow and the possibility of disassembly are examined, and if it can be easily removed, a fixation or locking solution is required.
If the test lid is a cork, shouldn't you need a sensor?
The frequency of application and actual behavior of tool use are evaluated, and the risk reduction for a fast-access cover may not be sufficient for the sole case.
Can we reverse-engineer the lock?
If the opposite direction has been confirmed to affect mechanical design, connected equipment and the discharge point, control mode can be defined; not assumed as an automatic solution.
Is the ATEX label necessary for the powder in the heloton?
The combustible and explosive properties of the material, concentration, zone and fuel sources cannot be determined without determining.
What hygiene risks does stainless steel not solve in food herring?
Surface finish, sources, bed position, drainage, residue pockets, counter and cleaning method are also evaluated.
Should the emergency position of the helix operating under the silo shut down the silo?
The safe sequence with the input valve or feeder is determined and tested in the actual failure scenario as to whether the material flow continues to sustain the hazard.
