high quality european standard destoner for flour mill

 Description of De-stone

Equippment for cleaning section

De-stoner separates the impurities according to the suspending speed difference in the air between wheat and the same size heavy impurities. Gravity de-stoner is a device which intergrates grading and de-stoning functions.

Operates on the cacuum principle . Steel base frame with sieve slope asjustmenmt. steel sieve box is supported by special hollow rubber blocks. Withdrawable wooden sieve frames,covered with steel screens, steel diffuser baffusers and cube-shaped cleaners. Integrated product distribution system. 

Plexi-glass inspection window, access openings closed with rubber covers. Final separation device for the stones is adjustable. Commom board accommodates the product inlet, aspiration  connection and air regulating valve with cacuum indicator.Outlets equipped with rubber sleeve valces.

Collection funnel for product outlet.

Oscilating drive 2*0.25kw

Hebei Africa Machinery Co., Ltd is specialized in grain processing equipment including flour milling machine, animal feed machine and grain silos. We have modern production workshop, advanced professional design, producing and installing group, scientific managerment mode, strict quality inspection to supply high quality complete sets of flour milling machines for wheat, corn/maize, rice, rye and barley, etc. Based on the advanced technology, good quality and reasonable price, we have very good reputation in the world market.

The process of flour milling (from wheat to milled into wheat flour) usually consist of the following: 1. wheat storage (silos, or warehouse) ---------- 2. cleaning system (sifter, destoner, seprater, magnet, scourer, etc) ----------- 3. dampening (dampener, conditioning silos, etc) ---------- 4. milling system (roller mill, plansifter, purifier, impact detacher, etc.) ---------- 5. Flour pressure and blending system (if need) ---------- 6. flour packing and stacking

We installed flour mill project in Ireland, Mexico, Argentina, Ecuador, Australia, Indonesia, Russia, and so on. In our country-China, we installed many projects, such as 500t/24h, 400t/24h, 220t/24h, 150t/24h, 120t/24h, 100t/24h.

The raw material (wheat, maize/corn, rice, etc) need to be cleaned before dampening to remove all kinds of impurities, like stick, mod, stone, iron, etc by sieve, de-stoner, magnet, etc.

After first cleaning, the material need to be dampened and conditioned in silos to suitable moisture contained, then start the second cleaning before milling.

After second cleaning, the material is clean enough to go to milling section.

Roller mill break the material, and plansifter separate the suitable size flour, purifier will extract the pure flour, semolina, etc.

After milling section, the flour will be packed into bags or stored in flour silos, or go to flour tanker.

PLC system, fully automatic controlling system with a lot of balancer, sensor, etc.
