- Slate line machines and which parts wear out firstA fibre-cement sheet line is a chain of stages: raw material preparation, milling, fibre opening, the forming machine, press, curing, demolding, autoclave, cutting. What wears out first is whatever rubs against the slurry and the sheet: forming felts, screens, knives, shaft bearings and slurry pumps.
- Forming felt for sheet lines: how to choose and when to changeChoose the felt by the slurry the machine runs on (asbestos cement or fibre cement), the type of fabric (woven or needle-punched), the density in g/m² and the exact width and length of your machine. Change it when it clogs and drains poorly, stretches or starts to mark the sheet.
- Spiral dryer fabric: what 820A, 831B and the grams meanSpiral dryer fabric is a belt of plastic coils linked by pintles. It is fitted in the dryer section of a paper or board machine in place of dryer felt. The plant's designation encodes the coil size and whether there is a filler, and the grams are the weight of a square meter of fabric.
- Corrugator spare parts: what wears out and what is ordered mostA corrugator wears where paper rubs, bends and is cut: corrugating rolls and the pressure roll or belt of the single facer, glue rolls, double backer belts, slitter and cut-off knives. Next to them are bearings, belts, motors and pneumatics. Standard items can be ordered by number, knives and rolls by drawing or sample.
- Printing press spare parts: what can be sourced in China and what notFrom China you can order standard parts: bearings, belts, motors, pneumatics, sensors, and also shafts, knives and roller rubber to a drawing or sample. Units with the press maker's number, such as control boards, proprietary mechanisms and software, are safer to take from the maker: a compatible copy can be found, but the risk is yours.
- Steam boiler for a workshop: which fuel and which designA boiler is chosen from the fuel you always have and from how much steam, and at what pressure, the workshop needs. Gas and liquid fuel call for a fire-tube boiler with a burner. Coal and biomass call for a boiler with a grate. Wet biomass, slag and low-grade coal call for a fluidized bed boiler.
- Scissor, mast or articulated lift: which one you needIf you need to rise straight up and work on a wide platform, take a scissor lift. If space is tight, the floor is weak or the door is narrow, take a mast lift. If a machine, a stack or a bay is in the way and you must reach across it, take an articulated or telescopic boom lift. After that, choose travel, power and height.
- Yard ramp or dock leveller: how to load a truck at a warehouseIf the warehouse has no loading dock, take a mobile yard ramp: the forklift drives up it into the truck body straight from the yard. If there is a dock or one is being built, fit a dock leveller in the opening: it bridges the gap and the height difference between the warehouse floor and the truck bed. A lift table brings the load up to workstation height, a tilter turns it over.
- Cement plant spare parts from China: what is ordered and howAt a cement plant what is changed most often is what rubs against clinker and raw meal: grinding balls and mill liners, kiln lining, filter bags, elevator belts and buckets. Next come large bearings, gearboxes and kiln rollers. Standard units are ordered by number, cast wear parts by drawing or sample with the material grade.
