Unique Zhengchang Hammer Mill Technology

The company received the industry’s first national patent for a hammer mill.

In designing and manufacturing its hammer mill, Zhengchang uses an advanced multi-chamber structure to prevent material build-up and increase production capacity.

Grinding efficiency is up 30 to 50 percent, particle fineness and product uniformity are up to 30 percent higher, and grinding temperature is reduced by up to 0.5 °C.

The unique hammer mill design extends the life of the hammers and screen, especially the screen holes.

The professional rotor design ensures steady rotor movement and keeps the grinding chamber temperature low even when the hammers are worn. It also improves the screen’s resistance to pressure and allows it to be folded and packed safely and reliably.

The Zhengchang hammer mill has a load control system for grinding and a closed-loop load circuit that improves operating efficiency and prevents overload.

Closed-loop interlock control of the main motor, pulse fan and pulse solenoid valve keeps the main motor and pulse fan running after a power cut, reducing dust build-up in the bags and improving suction in the pulse filter bags.

A pulse blockage alarm ensures the hammer mill chamber operates under negative pressure. A main shaft temperature alarm improves main motor stability.

An advanced grinding chamber design with a modified air path and a larger chamber gives more room for grinding. The material path has been changed and material circulation improved. The machine base is also designed to increase efficiency and operating stability.

The innovative design makes the machine suitable for grinding fibrous materials, high-moisture materials and coarse oily raw materials, especially dried fish feed, cottonseed, corn, shrimp feed, beans, plant materials and high-moisture corn (17–24 percent). It can run at full load without screen blockage. Product uniformity is higher. Screen sizes can range from 1.2 mm down to smaller sizes for coarse, medium, fine and very fine products. The machine is highly efficient and material does not stick to the screen.

The most advanced technologies are used in building the vibrating hammer mill.
