Twin-Shaft Kiln

The MTW European Type Trapezium Mill adopts 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. The integral bevel gear cuts loss and failure points versus bel

The Raymond Mill is ideal for non-flammable, non-explosive materials with Mohs hardness below 7 and moisture under 6%, such as limestone, calcite, dolomite, marble, gypsum, heavy calcium carbonate, bentonite, kaolin, bauxite, barite, talc and feldspar.

Small single‑drum models run at 3‑8r/min; medium‑large ones run 1.5‑6r/min; three‑tube dryer shaft rotates 4‑10r/min. Higher speed increases material‑showering frequency yet shortens residence time. Lower speed extends drying time with reduced throughput. Production shall balance capacity and drying result. Never adjust speed beyond model‑specified range, otherwise supporting rollers and blocking wheels will suffer accelerated wear.

Choke‑feeding means keeping the upper crushing cavity continuously filled with material, which is essential for inter‑particle crushing. It does not mean jamming the chamber but maintaining proper material height inside observation window with steady

Qualified fine powder enters the cyclone collector for gas-solid separation and is discharged by a rotary valve; ultrafine fractions are captured again by the pulse collector. Product is pneumatically conveyed to silos or ton-bag packers for automated fi

S5X circular vibrating screen can be equipped with 1‑4 screen decks; deck quantity determines number of finished fractions. Single deck is for simple pre‑screening to remove large impurities. Two decks produce three material fractions. Three decks ou
