Three Head Mortar Grinder

Product Structure

This Laboratory three heads mortar grinder mainly comprises the upper three sets of grinding heads, clutches, mortar supports, motors, localizer and other parts.
The grinding head, mortar support and clutch are evenly installed on the swivel base at 120° each other. The support plate and electrical equipment are installed on the front of the base; a motor is installed on its left side. To meet the requirements of grinding various materials, there are partitions between the three pairs of grinding tools to prevent samples from mixing with each other.

【Working Principle】
1. Loading: Lift the grinding head up and place it on the seat cover, take off the cover on the mortar, put the material to be ground into the mortar, put the cover on, and put down the grinding head.
2. Grinding: Start the motor and turn the clutch handle clockwise to close the friction clutch to make the grinding head and mortar rotate to grind the material.
3. Unloading: Turn the clutch handle counterclockwise to disconnect the friction clutch, so that the pestle and mortar stop moving. Lift the grinding head and take off the bowl cover, and put the material receiving container on the corresponding position of the material receiving rack. Turn the long handle located to the left of the mortar so that the mortar swivels up to rest above the catcher. Use a brush to brush the powder in the mortar into the receiving container. After the material is unloaded, reset the mortar and start charging again.
4. Transposition: When the motor is rotating and the grinding head needs to be exchanged, use your left hand to lightly press the locator handle cover at the lower left of the receiving frame. The upper part of the mill can rotate by itself, and when it turns to 120º, that is, when the other mortar reaches the discharge position, it stops automatically. When it is necessary to transpose when the motor is not running, the operation method is the same as before, and you need to lightly turn the turntable with your right hand.
