1. The general grinding output of the state invention patent Zhengchang E type champion king grinder increases 30% than the same trade. Electric consumption of one ton output of fine grinding reduce 3-4KW. Take the feed plant's annual feed production 100,000tons as an example,the raw materials is 70%,the industrial electricity 0.6RMB/KW,every year can save electricity 100,000 tons × 70% × (3KW-4KW) × 0.6RMB/KW=126,000RMB-168,000RMB. Take the feed plant's annual feed production 200,000 as an example, every year can save electricity 252,000RMB-336,000RMB. Take the feed plant's annual feed production 300,000 as an example, every year can save 378,000RMB-504,000RMB. Use Zhengchang new model champion king grinders, the investment can be returned in half a year or one year from efficiency improvement and processing cost of grinding section is lower from now on. Besides output raise,Zhengchang new generation grinder, the grinding fineness and noise leads same trade,grinding fineness is near to micro grinding effect, saving money of one set of micro grinding machine.Zhengchang new generation grinder increase stone and sand removal device,more suitable for high-grade pig feed,suckling pig feed and pet feed processing, providing a new high-efficiency and energy saving equipment for improving the high-grade feed quality.

2. Patent design of assembling multi grinding chambers,the secondary efficiency of shrimp feed and premix improved above 30%, the efficiency of raw materials direct fine grinding improved above 30%.

3. Multigroup shear plate design, increasing shearing action,destroying circulation layer,grinding efficiency improved above 30%.

4. Entering wind in side direction, changing wind field of grinding chamber, improving grinding efficiency and reducing working temperature of main shaft. Eight groups of hammer design increases probability of collision of hammer and materials and improve grinding efficiency.

5. Patent design of assembling multi grinding chambers, increasing the useful life of hammer and sieve plate greatly,especially the small bore sieve plate.

6. Professional design of innovative rotor assembly,rotor runs more smoothly, although the wear and tear hammer and lower temperature of grinding chamber.

7. Equipped with grinding load controlling instrument,realizing closed-loop control of load current and feeding quantity,improving grinding efficiency and preventing overload production.

8. The delay closed-loop chain control of main electric motor,impulse fan and impulse solenoid valve,ensure main electric motor and impulse fan after power failure,solenoid valve continues working,reduce dust attached to bag, ensure air permeability of pulse bag.

9. Pulse bag blocks alarm,ensure grinding chamber runs in rated negative pressure.The setting of main bearing warning system improves persistent stability of main drive.
