Introduction:
ZHM Huawu Steel design and manufacture heavy duty hoppers, feeders & frame conveyors for all industrial and commercial applications,These designs performs in tough environments while protecting the product from the weather conditions, capturing of dust emissions, while limiting the risk of igniting flammable products. Common options include: trussed frames, walkways, service platforms, support bents, transfer towers, and reloading tail sections.
Crushing stations are just one of the many elements that make up a processing plant. No matter what the capacity or the material your plant is processing, ZHM Huawu Steel can help design, fabricate and install a crushing station that will serve the purpose well. We have experience in designing for all stages of crushing which also includes the satellite elements such as hydraulic breakers, retaining walls, operators control buildings and the structural steel associated with each element. All of our crushing stations can be fully enclosed to satisfy any dust or noise control requirements a producer may encounter.

2.1 Cutting
.1 Where the ends of members are to bear in compression, the ends shall be cold sawn and then machined so that the loads are evenly transmitted over the entire area of the section..2 In all other cases, setting may be by shearing, cropping or sawing. Notches or other shaping to the ends of members shall be formed by cold or hot sawing.
.3 Machine Flame cutting may be used only where approved, in writing by the Owner.

2.3 Welding Operations
.2 Stud shear connectors, where specified, shall be welded in accordance with the manufacturer's instructions.
.3 For any load-bearing structural parts, columns, crossbeams, diagonal stays, etc. an allocation of the welder to the seams welded by him is to be ensured. This can be achieved by a stamping of the seams with the relevant welder's number or allocating of the welder stamp by marking in a drawing/sketch.
a. For every welding procedure and filler metal (type designation according to the standard) for steels ≤ S355,
b. For every welding position which occurs in the production
c. Steels > S355 separated agreement.
d. Fillet welds shall be qualified separately and shall not be covered by butt welds.

according to EN/ISO.
a. The technical qualification must have been proved.
b. The scope of qualification must cover the welder’s/operator’s scope of app
4.2.3. Quality of Welds
.1 All slags, weld spatters, ignition points and deposits due to welding must be removed. Any auxiliary materials resistant to spatters are subject to the explicit approval by Owner.
.2 Any inadmissible notches must be removed in a professional manner – primarily by flush grinding, in particular cases by re-welding.
.3 Preheating and temperature of intermediate layers, rate of cooling and as required heat control and heat application depend on the specifications of each applicable welding procedure qualification test (WPQR/ WPAR).
.4 A sufficiently wide and homogeneous heat distribution (≥ 50 mm on both sides of the groove as a function of the component thickness and ambient temperature) is to be ensured.
.5 Welding points must be protected against harmful weather influences, e.g. precipitation, condensation water, draught and wind.
4.3. Testing of Welds
.1 Owner reserves the right to demand test welds. The weld seam quality is evaluated according to the criteria of standard EN ISO 5817 (see also below Table).
.2 The following testing shall be applicable to non-destructive tests:
- a. (VT) Visual inspection
- b. (PT) Dye penetrant inspection

4.4. Payment For Testing
.1 ZHM Huawu Steel, as the Manufacturer, will include in his rates for the cost of providing and using equipment for the non-destructive testing of welds (radiographic, ultrasonic, dye penetrate and
magnetic particle), during fabrication and on site as required by the radiographic films and other test results and reports available to the Owner.
.1 Steel plate work shall be protected against corrosion by the application of coatings as shown on the drawings and specified below. The EU/ISO standards and guidelines shall be binding for the corrosion protection, unless otherwise specified by Owner.
4.5.1. Surface Preparation
.1 The surface preparation of any non-galvanized parts shall be done by means of dry abrasive blast cleaning.
.2 In this respect, all steel parts including the weld seams are de-rusted according to EN ISO12944-4 immediately prior to the application of the primer coat by means of dry abrasive blast cleaning at least until the standard preparation grade Sa 2½ is reached. For any cast parts of metal an
equivalent pre-treatment is taken for granted.
.3 For any non-galvanized parts any rust, welding residues, weld spatters, slag, burrs, salt, atypical impurities and similar must be removed from the surfaces prior to blast-cleaning. Rust, weld spatters, slag, burrs must be removed. Any boreholes shall be considered as surfaces and
accordingly prepared in an equivalent manner. Any existing edges from flame cuts, saw cuts, punched holes and cutting work, etc. shall be chamfered. Any screw holes and boreholes shall be deburred.
4.5.2. Application of Painting
.1 The application of the factory-made coating(s) shall be affected in closed rooms by airless guns. All corners, clearances, screw holes and hardly accessible areas must be pre-painted after the surface preparation. The primer coat shall be applied immediately after blasting. For the application of the intermediate and finishing coats the rework periods shall be complied with according to the manufacturer's specifications.
.2 The specifications of the paint supplier must be followed with priority.
.3 For the storage and processing of the coating materials the regulations of the coating manufacturer shall be additionally observed.
.4 Before the start of any corrosion protection work the Contractor must inform the Owner as follows:
- a. execution site
- b. period of execution
- c. any commissioned subcontractors
- d. any applicable coating materials and coating systems incl. manufacturer ZHM Huawu Steel
.5 Inspections of the corrosion protection work shall be made possible to the Owner, the coating manufacturers and any companies commissioned with the application of the later finishing coats at any time and without prior notice.
.6 The specified film thicknesses are to be understood as nominal dry film thicknesses according to EN ISO 12944-5. In this respect, any individual values of the dry film thickness, which are below 80 % of the nominal dry film thickness, shall not be permissible. Individual values between 80 % and 100 % of the nominal dry film thickness are permissible, provided the mean value of all measuring results is equal to or greater than the nominal dry film thickness.
.7 For the max. film thickness the data in the Technical Data Sheet of the coating supplier shall be applicable. If no data is contained in these data sheets, the max. film thickness must not be greater than three times the nominal dry film thickness.
.8 For any applied factory-made coating systems with multiple layers the coating materials shall be purchased from the same manufacturer.
.9 In case of any contact surfaces of pre-stressed screwed connections the contact plate surface may only be provided with a prime coat. A thickness of max. 60 μm is sufficient.
