three head grinding mill

Product introduction
The three-head grinder is a kind of grinding equipment for dry grinding and analyzing samples. It is mainly used for grinding and analyzing samples in the laboratories of metallurgy, building materials, chemical industry, coal, hydropower, commodity inspection, geology and other departments. It can also be used for grinding and analyzing samples by relevant parties. Fine and generally used for a small amount of materials. The mortar and pestle can be made of ceramics, corundum, alloy steel and other materials according to the special requirements of users.



Product application
Application field: It is used for grinding and analyzing samples in the laboratories of metallurgy, building materials, chemical industry, coal, hydropower, commodity inspection, geology and other departments, and also for grinding general small amount of materials.
Equipment advantages: The three-head grinding machine is a grinding equipment for dry grinding and analyzing samples. It is equipped with time digital display and timing device.
Working principle: This machine is mainly composed of three sets of grinding heads, clutches, mortar supports and positioners. The grinding head, mortar support and clutch are evenly installed on the turntable at 120° to each other. The turntable is installed in the bearing of the base. The front of the base is equipped with a receiving support plate and electrical appliances, and the left side is equipped with a motor. When the clutch is turned on, the motor drives the grinding head to rotate through the pulley, gear shaft and universal joint. The other end of the gear shaft meshes with the gear of the mortar support. Due to the relative sliding of the forward rotation of the pestle and the rotation of the mortar in the same direction, the weight of the grinding head generates pressure to grind the material. The clutch is a normally closed dry friction clutch. The coupling and disengagement of the friction clutch is realized by the up and down swing of the lever around the support pin. When the lever is raised, the spring is compressed and the friction plate is disengaged from the gear. When the lever moves down, the spring returns, and the friction plate fits with the end face of the gear, thereby transmitting power. The up and down movement of the lever is realized by the joystick. When the handle is on the right, the clutch rotates counterclockwise to the left, the shaft installed in the turntable pushes the pin by eccentricity, and the adjusting screw of the lever is pushed up, and the lever swings upward to disengage the clutch. During use, when the friction plate is worn, the nut can be loosened and the adjusting screw can be adjusted downward. Since each pair of laps has a separate clutch operation, the movements of the three pairs of laps do not affect each other, so they can work at the same time, or one or two of them can work.
