Category overview: https://www.jianqiangjx.cn/en/categories/

### 1. Bin Tipping & Dumping ★ Export priority
- Bin tipping machine / covered bin tipping machine — stationary tipping station
- Single-arm lift and dump, movable dumper, barrel-holding vertical lift and tipper — bag, drum and bin handling
- Bin lift and tipper, single-bucket lift and tipper — lifts a bin and tips it into a silo or mixer
- Double-arm lift and dump — eight load ratings: 200 / 300 / 450 / 500 / 700 / 1000 / 2000 / 3000 kg
- Twin roller chains in 16A / 20A / 24A / 28A / 32A; rail in rail steel, square tube or 12# channel Q345
- Motors: 2.2 / 3 / 4 / 5.5 / 7.5 / 15 / 18.5 kW brake motors, sized to the load
- Construction: twin-chain drive, the container returns to floor level for a second feed cycle;
  upper and lower limit switches plus a 0–50 s adjustable timer
- Control cabinet: electrical components, overload protection, limit switches, remote signal interface;
  optional explosion-proof control cabinet and button box
- CE-certified components available on export builds; full SUS304 stainless body

### 2. Mixing Equipment ★ Export priority
- 500 L vertical mixer — small-batch powder blending
- Single-drive dual-shaft mixer — counter-flow top to bottom, higher blend uniformity
- Horizontal twin-paddle mixer — large-batch powder and granule blending
- Polished product chamber, no dead corners, suitable for food and pharmaceutical duty

### 3. Screw Conveying
- U-type screw conveyor (Ø140–Ø350) — horizontal and inclined, the general-purpose workhorse
- Shaftless screw conveyor — no central shaft; moves sticky, fibrous, filter-cake and sludge materials
- Twin-screw conveyor — high throughput with gentle mixing in transit
- Quick-release screw conveyor — opens for washing and product changeover, food and pharmaceutical lines
- Materials of construction: SUS 304 / 316L stainless steel, Q235B carbon steel, PP flighting

### 4. Feeding & Metering
- Ø159 round-hopper and Ø219 geared screw feeders — pick up from a hopper into the next process step
- Twin-screw extruders with irregular flight blades — force feeders that break arches for sticky materials
- Screw metering feeder — volumetric dosing in SUS316L for chloride-bearing service,
  optional loss-in-weight module

### 5. Vertical Lifting
- Z-type bucket elevator — compact vertical lift
- Scraper (flight-chain) elevator — for dusty, sticky or wet material
- Vertical bucket elevator — C-type continuous bucket layout, Ø254 × 3 mm tube, gravity discharge,
  automatic residue return
- Bucket elevator (rotating bucket type) — 304 stainless, 3–5 t/h, ~5100 mm lift, 1.8 L PE buckets,
  1:80 reducer, 2.2 kW motor plus 0.8 kW vibrating feeder at the inlet

### 6. Storage & Anti-Bridging
- 60 m³ slide-frame silo with anti-bridging structure
- Bridge-breaker + screw feeder combinations — the standard fix for powder arching in silos,
  breaker agitator on top and twin screws at the outlet

### 7. Crushing & Valving
- Two-shaft wave-tooth crushers — agglomerate and lump reduction
- Three-way diverter valve, eccentric three-way valve, pneumatic three-way valve — routes a
  powder line between two or three destinations

### 8. Conveying Support
- Belt conveyor — bagged goods, cartons and pallets, plus bulk transfer

## Five Handling Solutions

1. **Sticky and viscous material handling** — scraper elevator + shaftless screw for filter cake,
   wet sludge, molasses and pastes. Outcome: no clogging, no wall build-up, stable continuous discharge.
2. **Powder anti-bridging (arching) systems** — sliding-frame silo + bridge-breaker + twin-screw feeder.
   Outcome: arching broken reliably, uniform discharge rate, throughput recovered.
3. **Sludge dewatering and drying lines** — shaftless screw + scraper elevator + buffer silo, from
   filter-press cake to the dryer inlet.
4. **Food-grade conveying (GMP)** — polished stainless construction, quick-release design, no dead
   corners, suitable for CIP cleaning.
5. **Explosion-proof conveying** — CT4 dust protection and Exd IIB T4 gas protection for flammable
   atmospheres.
