Shaft Kiln

It is built for manufactured sand; product size is usually 0 to 5 mm, adjustable to standard sand (e.g. 0–4.75 mm) or fine/medium grades. With classification and air-material control it yields well-graded, well-shaped sand for concrete and mortar.

Metal pieces break through material bed instantly and trigger violent vibration, local chipping of roller sleeves and table liners, even damage reducer gear pairs. Manual inspection cannot fully block metal impurities. Install iron remover plus metal‑d

Single‑drum dryer capacity covers 0.5‑160t/h. Min model φ600*6000 reaches 0.5‑1.5t/h; max φ3600*25000 reaches 95‑160t/h. Real capacity depends on incoming moisture, target final moisture, particle size, inflow temperature and rotating speed. Higher feed moisture reduces actual output. Max inflow temperature is 700‑800℃. Real throughput calculation requires material test data instead of nameplate value only.

Qualified powder is captured by the bag collector and sent via rotary valve and air slide or pneumatic pump to the product silo. Negative-pressure operation ensures high recovery with no dust, and can link with homogenizing and bulk-loading for storage a

Equipped with intelligent electric control cabinet, it realizes automatic control over feeding, grinding, classification and collection. It supports connection to upper‑level central‑control system for remote parameter monitoring and fault alarm disp

Adopts spiral bevel-gear integral drive: the main motor drives the central shaft via a reducer for a short chain and precise ratio with smooth, efficient power. Versus belt or multi-stage drives it cuts loss and failure points.
