MMT pneumatic milling machine

Application:
The roller mill is the main equipment for milling section in flour mills. It mainly depends on a pair of differential transmission and relative rotation rolls to break wheat, meanwhile, scrapes endosperm from wheat bran, then endosperm grinding into flour. The material can be extruded, sheared and broken during the equipment working and so as to achieve a certain grinding effect, each roller mill has two independent drive, feeding, and grinding systems and play their functions in the flour passages.

New technology of MMTL Eight Rolls Pneumatic Flour Roller Mill:
1) Two breaking systems or two reduction systems connection directly without middle sieve
2) Both saving plansifter area and save the cost of pneumatic conveying 
3) Saving equipment investment cost and building area occupation.

Features:
1) Rolls lay out horizontally, the material is easy to grinding area, and rolls are easier assembly, disassembly and maintenance;
2) Full pneumatic control, the machine can be controlled independently or be controlled concentrated through a remote panel;
3) The fast and slow grinding rolls are driven by triple-wheel teeth wedge belts with advantages of no jump teeth, no deflection, smooth operation, and low noise;
4) Adjustable and standard self-aligning roller bearings are used for the grinding rolls to ensure highly concentric precise with rolls running, and sustain high speeds and roll pressures;
5) High quality double heads centrifugally casted rolls with dynamically balancing testing ensure smooth running and long service life; 
6) Rolls are adopted the eccentric lever clutch structure, damping beams alone support, roll groups self- undertake running stress; 
7) Reduction system is adopted gap air flow pressure device; it can improve the feeding condition, reduce rolls and materials temperature, and improve grinding efficiency;
8) The upper and lower split structure is designed for the two side frames of roller mill; the damping washer is fitted in the upper and lower connection point;
9) The completely enclosed structure is adopted for the machine, the static electric sprayed paint technology is used in surface treatment.
