laboratory size reduction mill for stone

Features of lab size reduction mill:

1.Stable. Stable revolving speed of the gear transmission. Ensure the working consistency & repeatability

2. Efficient. Four jars work together. Produce 4 different size & different material samples at the same time.

3. Functional. Rotation speed Adjustable.

4. Safe. With safety switch installed to avoid machine run when the cover open

5. Safe. The frequency converter has low-voltage and over-current protection function. Protect the motor successfully.

6. Convenient. With self-timing power off, self-timing forward and inversion function. Raise the efficiency by choosing one-way, alternately or continuously rotation method with timing or not as required.

7. Perfect. Functional with low barycenter, stable performance, compact structure, easy operation, reliable safety, low noise & low waste.

Areas of Application:

1. Ceramic.

2. Pigment. (Paint/ink/color/coating)

3. Agriculture. (Tea / Chinese herb / plant / Coffee beans / etc)

4. Pharmaceutical production (Medicine/Drug)

5. Solid waste treatment. (Soil / metal / Plastic)

6. Mine. (Ore/stone/metal/litharge/lithium/alumina/coal/chrome/graphite/ lead/etc)

7. Construction ( Stone / glass / cement / concrete / sand / slag )

8. Powder metallurgy; / Abrasive materials;

9. catalysts production and recycling;

10. Chemical.

11. Others (Comestic / makeup / clinker / pearl /linestone / etc )


Working Principle:

The grinding sample is comminuted by high-energy impacts from grinding balls and friction between balls and the grinding jar wall.

Main Programs

Single direction without timing: samples need long or non-stop milling

Single direction with timing: samples need to be milled in one direction for a designated amount of time before automatic shutdown

Bi-direction with timing: i.e. samples need to run clockwise for 1.5 hours, then counter-clockwide for another 1.5 hours and so on, for 15 total hours, before the machine shuts down itself

Single direction with paused interval and timing: i.e. samples need to run for 0.5 hour, then pause for 1 hour, then run for another 0.5 hour in the same direction and pause for another 1 hour, for 10 cycles before auto shutdown

Bi-direction with paused interval and timing: i.e. samples need to run clockwise for 0.8 hour, pause for 0.5 hour, then run counter-clockwise for 0.8 hour, for 20 cycles, before auto shutdown.


Please note: For this DECO mill, you require two or four grinding jars of your choice and the corresponding number of grinding balls. The grinding jar material must also be harder than the material to be ground. In normal cases, grinding jars and balls of the same material are used. To shorten the grinding time, larger or heavier grinding jars and grinding balls with a higher density can be used. However, the standard packages of the mill doesn't include the grinding jars or balls. They must be ordered as accessories.
