1. Application and suitable scope

JFS2000MG hammer mill adapts “Dripping-shape” structure and it is the latest crushing technology and manufacturing process introduced from abroad. It is suitable for crushing many materials such as dried cassava, maize, bean cake, sorghum, soybean, conch and stem, which is widely used in the alcohol, grain, feedstuff, citric acid, starch and other industries.

2. Main specifications and technical parameters

Note:

1. The reference productivity in the above table is the crushing output when the crusher is with correct installation, good suction, the negative pressure under the sieve ≤ 700～1000Pa, standard high porosity sieve plate, and the moisture content ≤14％.

2.The productivity is only for model selection reference. If there is any special requirement, it can also be designed separately.

3. Main structure and working principle

1) For structure diagram and installation foundation, please refer to Figure 1.

2) Working principle

Material is fed from the top inlet and will enter into the crushing chamber through the feeding guide mechanism. The material is struck by high speed rotating hammerer, so it is crushed by being rubbed and struck in cycles and cutting function of punching sieve. Meanwhile under the action of centrifugal force and air stream, the material of qualified granularity will pass through the sieve pore and discharge from the outlet under the base. Customer can adapt multiple auxiliary equipments to finish the work such as material collection, conveying and warehouse entry based on the specific process.

4. Operation

1,Operator should be familiar with the machine’s performance, understand its structure, and learn the Operation Instruction seriously.

2,Before starting the machine, check each connection part carefully, no looseness is allowed.

3,Check whether the rotor rotation is flexible and there should be no abnormal noise.

4,Increase feed quantity gradually after no load running for 2～3 minutes.

5,Before stop the machine, first stop feeding, discharge all the remaining material in the machine, and then it could be stopped.

6,The rotating direction of main shaft is determined by different feeding direction. The rotating direction of motor is controlled by manual direction control of guide mechanism. Before opening the door, power supply should be switched off. When the door is opened, crusher will stop and meanwhile the motor can not be started, to guarantee the safety and reliability when replacing damageable parts and doing maintenance. After maintenance is finished and the door is closed, put the handle of feed guide plate in the correct position in accordance with the needed rotation of motor.

5,Maintenance and troubleshooting

1,Maintenance

＜1＞Operate strictly in accordance with the operation methods; every shift should do the necessary inspections and cleaning work.

＜2＞After the machine’s every working time of 4000－5000 hours, the bearings should be removed and washed once.

＜3＞Do repair or replacement immediately when the components are damaged or badly worn. The rotor should be taken for dynamic balance correction after repair or replacement.

＜4＞If the down time is long, both inside and outside of the machine should be cleaned up and remove the dustiness, to prevent corrosion and the sieve pore blocking.

＜5＞For long-term storage, the machine should be placed in a ventilated and dry place, and rain-proof measures should be taken when stored in the open air.
