The machine with a stainless steel casing is a tabletop machine and has standard specifications.
Currently, desktop machines are available from size 101 (0.2ℓ) to size 22 (4ℓ).
If you would like a stainless steel housing for machines of 7 liters or more including large machines or conventional machines,
We will respond individually (as an options), so please contact us.
Please contact us for stainless steel coating that has durability and rust prevention effect.
It is an option, but it is possible by setting the rotation speed on the inverter and programming on the control panel.
Please contact us .
The Desktop model（D series） can be changed in standard specifications.For the conventional type, the rotation speed can be changed by installing an inverter (as an options) Please contact us if you wish to install the option.
It has been confirmed that the Ishikawa type stirring and crushing machine D series (stainless steel housing) operates the machine in an atmosphere of inert gas such as argon gas or nitrogen gas in the glove box.
However, please contact us when using the machine in a decompressed (vacuum) glove box.
The conventional machine of the Ishikawa type stirring and crushing machine has a control panel of the machine, electric wiring, and an electric system such as an explosion-proof motor that is outside the explosion-proof area, and the pulleys and belts are used to drive the motor power to the machine shaft and It is moved to the mechanical part such as gears.
Please contact us for details when using in the explosion-proof area.
The Ishikawa type stirring and crushing machine puts the material into the open type mortar for processing, so while operating the machine, check the state of the material in the mortar (visually) or stop the machine. It is easy to take out a part of the material and check the progress of the processing. Since you can check the condition of the material to be processed, you can change the processing conditions such as adding additional material or changing the rotation speed of the pestle, which is very convenient for condition setting in product development.
The crushing function of the Ishikawa type stirring and crushing machine has multiple functions such as grinding, compression and shearing.
While selecting the most suitable machine according to the conditions such as the type of material and the throughput, we also offer individual support such as improvement.Please contact us for details.
The contact point with the mortars and pestle top of the Ishikawa type stirring and crushing machine is By moving along with the rotation of the pestle, the grinding force is repeatedly applied to the foil to gradually crush the foil.
Please contact us for the prescription and handling method for foil metal as well depending on the type and amount.
Experienced staff will respond.
Depending on the input amount (processing amount) of the material, the high viscosity band can be processed up to about several hundred thousand mPa sec as a guide.When processing high-viscosity materials, it is recommended to use with a dosage that is less than the "processing volume" set for each machine size.
Larger machines tend to have higher stirring and crushing capacity.
Regarding the relationship between material viscosity, input amount, and processing volume, we recommend that you evaluate your material after processing it with an actual machine.
Also, during the experiment, our experienced staff can help you with the actual processing of the material together with you.
The size that can be crushed depends on the processing material.
Depending on the processing method and material, micron-level crushing is possible, but we recommend that you evaluate your material by processing it with an actual machine.(Please contact us "Inquiries regarding machine selection")
There are several ways to adjust the agitation force of the machine.
By changing the spring constant built into the pestle, you can adjust the force with which the top of pestle pushes the mortars, change the shape of the pestle (the pestle), change the material of the pestle, agitate/rotate the machine . Please contact us
We have an EB type machine that uses electric heat to boil water. Product guide EB type (electric hot water roasting type)
By attaching a heat insulating material to heating and cooling type (the EB type) of the Ishikawa type stirring and crushing machine and using oil instead of hot water as the heat medium, it is possible to perform stirring and crushing while heating up to about 120°C.
If you wish to perform stirring and crushing while warming to 120°C or higher, please contact us.
For stirring and crushing while cooling, the process is performed by putting cold water into the double pot (with outer pot) machine to cool the pot from the outside or connecting a chiller. If you would like a machine with a cooling device in the machine body, please contact us.
Lot management is possible for each mortar (pot). Processing with the Ishikawa type stirring and crushing machine is batch processing in mortar units, so lots from a small amount. Can be managed.
Please check if you can send us a picture of the nameplate or parts of the machine so we can judge it.
Please see the Maintenance page. You can see the how to check the nameplate and how to check the mortar type (model name)/serial number)
The inside of the porcelain mortar wears away due to friction with the pestle and friction with the processing material, and a step is created between the outermost track of the pestle top and the outside of the track.
If this step exceeds about 5 mm (for a size A porcelain mortar , the allowable size of the step varies depending on the size), there is a high possibility of damage due to vibration or shock during stirring and crushing. The size of the step due to the abrasion of this mortar is one guide, and the inside of the mortar may be worn unevenly, so we recommend that you bring a spare mortar in case of unexpected damage to the mortar.
Our company has machine design, assembly processing and each professional,
Since we are firmly inheriting the technology at the time of our founding 120 years ago and manufacturing parts,
Modification, repair, and overhaul are also available.
However, it may be expensive in terms of cost, so we will consult with you after making an estimate. ：
Please make sure that the power outlet is plugged in.
If the machine does not work even if the outlet is plugged in, please check if the original power source (whether the breaker is ON) is on or not.
Loosen the oil drain screw near the oil leak and drain the oil.
If you do not know how to remove the oil, or if the oil leakage does not stop even after removing the oil, please contact us.
Please check the model and serial number on the nameplate and , please contact us our design and sales staff will handle it.
You can use the experimental machine for trial in the introduction test room in our factory to evaluate the Ishikawa type stirring and crushing machine and respond to the experiment. Please contact us.
Please contact us with the materials and chemical names used in the introduction test room in advance.
The Ishikawa Kojo is located in Tatsumi, Koto-ward, Tokyo, including offices, introduction test rooms, and factories. How to access the Ishikawa Kojo
