Working principle of horizontal rod cone crusher;

When the equipment works, the rotation of the motor swings around the fixed part through the pulley or coupling, the transmission shaft and the conical part under the force of the eccentric sleeve, so that the crushing wall of the cone crusher approaches and leaves the surface of the white roller wall fixedly installed on the adjusting sleeve, and the ore is constantly impacted, squeezed and bent in the crushing cavity, thus realizing the crushing of the ore. When the unbreakable foreign matter passes through the crushing cavity or the machine is overloaded for some reason, the spring safety system realizes safety, the ore outlet is enlarged, and the foreign matter is discharged from the crushing cavity. If the foreign matter is stuck in the ore outlet, the cavity cleaning system can be used to continuously enlarge the ore outlet, so that the foreign matter can be discharged from the crushing cavity. Under the action of the spring, the ore outlet automatically resets and the machine returns to normal work. This series of crushers can be divided into three types: coarse crushing cone crusher, medium crushing cone crusher and fine crushing cone crusher, which can be purchased according to different needs of users.

In the main engine, the grinding roller assembly is hung on the grinding roller hanger through the cross arm shaft, and the grinding roller hanger is fixedly connected with the main shaft and the shovel frame. The compression spring is on the cantilever outer end face of the bearing chamber of the grinding roller, and takes the cross arm shaft as the fulcrum to force the grinding roller to press against the inner circular surface of the grinding ring. When the motor drives the spindle to rotate through the transmission device, the shovel mounted on the shovel frame rotates synchronously with the grinding roller, and the grinding roller rotates while rolling in the inner circle of the grinding ring. The motor drives the impeller of the analyzer to rotate through the transmission device. The higher the impeller speed, the finer the separated powder. Ball mill is the key equipment for crushing materials after crushing.

4. The wearing parts have low loss, so the wearing parts are made of high-quality wear-resistant materials at home and abroad, which has a longer service life than the wearing parts of ordinary mill equipment, generally more than one year.

Working principle of grinding production line:

The working principle of the machine: after the block material is crushed to the required granularity by the jaw crusher, it is sent to the silo by the hoist, and then sent to the grinding room of the main engine by the vibrating feeder for grinding. The ground powder is taken away by the airflow of the fan, classified by the analyzer, and the powder with fineness enters the cyclone collector with the airflow for separation and collection, and then is discharged through the powder outlet pipe to obtain the finished powder. Then the airflow is sucked into the blower by the air return pipe at the upper end of the cyclone collector. The whole air flow system of this machine is closed and circulates under positive and negative pressure. There is a certain water content in the material ground in the mill. The heat generated in the grinding process causes the gas in the mill to evaporate, thus changing the gas flow rate. At the same time, due to the lax sealing of the pipeline joint of the whole machine, external gas is inhaled, which increases the air volume of circulating air flow. Therefore, the air flow balance is achieved by adjusting the residual air duct between the fan and the main engine, and the excess air is introduced into the bag dust collector, and the fine powder brought by the residual air is collected, and the residual air is purified and discharged.
