Circulation Tube: suitable for low-viscosity materials that need recycling and reflux for grinding, such as soy milk, mung bean drinks, etc. Rectangle Inlet: suitable for high and medium viscosity materials that don't need reflux or grinding, such as peanut butter, chili sauce, etc. PRODUCT PARAMETERS 
Note: The type without machine seal is mainly appliable for processing materials of high concentration or sauce materials such as peanut butter, tahini, animal meat, fish, vegetables, etc. Note: The type with (double-end) mechanical seal can be connected to pipes for continuous multi-circulation, and the head is about 4 meters. PRODUCT STRUCTURE Colloid mill is a processing machine of fine grinding and crushing fluid materials, mainly consist of motor, adjust unit, cooling unit, stator, rotor, shell and etc, widely used in various industries. 
1.Both rotor and stator are made of stainless steel, the rotor rotates at high speed and the stator keeps static, which makes materials passing the toothed bevel bear great force of shear and friction. 2.There is a pair of conical rotor and stator rotating at high speed inside a colloid mill. When materials pass the gap between the stator and rotor, they bear great force of shear, friction, centrifugal force and high-frequency vibration, finally making materials ground, emulsified, homogenized and dispersed. 3.It's high efficiency of grinding ultra-fine particles by force of shear, grinding and high-speed stirring. And crush and grinding by relative movement of the disc tooth-shaped bevels. Colloid Mill is an ideal wet-crushing equipment. Materials are ground, emulsified, crushed, mixed, dispersed and homogenized under forces of high-frequency vibration and high-speed vortex. WORKING PRINCIPLE The basic work principle of colloid mill is that fluid or semi-fluid materials pass the gap between fixed tooth and rotation tooth which are relative high-speed interlocking to make materials bear strong shearing force, frictional force and high-frequency vibration force. Grinding is by the relative motion of toothed bevels, one rotates at high speed, the other keeps static. In that case, materials passing the toothed bevels are greatly sheared and rubbed. At the same time, those materials are under forces of high-frequency vibration and high-speed vortex, which make them ground, emulsified, crushed, mixed, dispersed and homogenized, finally fine finished products are achieved.
Rotation Disc and Static Disc High Shear High Speed 2,900RPM to ensure the quality of grinding materials. 
Q&A Question: Can the colloid mill grind corn, millet, soybeans, mung beans, red beans, rice and other grains? If yes, how fine can it be? What is the output? Answer: 1. Fresh corn (without water) can be ground for each model, and the grinding effect is better after adding water. The specific output is based on different models, please consult our sales staff for details. 2.The rice cannot be ground by adding water directly, but the rice that can be crushed by hand after soaking for a long time can be ground. It is recommended to add more water for grinding; 3.Regarding mung beans, red beans, mung beans and soybeans, it is recommended to soak them for a long time before grinding. The fineness of corn, red beans and mung beans after grinding can reach below 300 mesh, and the fineness of soy beans after grinding is about 80-150 mesh. The colloid mill is a fine grinding equipment, mainly used for secondary processing of materials. The higher the hardness of the material itself, the more difficult it is to be ground, and the greater the impact on the service life of the equipment. Different materials have different grinding fineness. If you need technical support, please consult our sales staff. Question: Can the colloid mill grind bones? Answer: The colloid mill cannot grind hard objects such as bones. The material is easy to get stuck in the cavity, wear the grinding disc, and cause the motor to load. Please do not do that. Otherwise, it may cause the equipment damage, that is man-made damage and not covered by the warranty. Question: Can the colloid mill grind seafood? What is the output? How fine is it? Answer: The colloid mill can grind seafood. Since seafood contains salt, its chlorine content is relatively high, and it is corrosive to metals. It is recommended to choose stainless steel 316L with better corrosion resistance for colloid mills. Stainless steel 304 has weak corrosion resistance and is easy to rust. Before grinding, it is recommended to compare the size of the seafood with the size of the hopper port of the colloid mill. If it is easy to block the hole, you need to choose a screw feeder, and better cut the seafood into small pieces to prevent blocking the feeding port, unable to enter the cavity, and cannot be ground. If you need more technical support, please contact us. Note: The flow data on the parameter table is based on the flow of water, not the actual material output. Question: What is the difference between the split type and the vertical type of the colloid mill? Answer: Their functions are the same, and their models of the same specifications have the same output. But they are different in appearance and structure. The motor of the split colloid mill is installed on the side, even after the equipment is working for a long time, the seal of its cavity is aging, causing liquid leakage, and it will not cause damage to the motor. The motor of the vertical colloid mill is installed directly and vertically at the bottom. If liquid leakage occurs, the motor may be easily short-circuited and cause damage to the motor. The split type has relatively better performance and higher price, but the vertical type is economical and more cost-effective. You can choose the most suitable type and model according to your budget and actual needs. Question: Can the colloid mill handle high-viscosity materials? Such as honey, oyster sauce, glue? Answer: High-viscosity materials can be directly discharged by the colloid mill, but it is necessary to consider the effect of high temperature on the materials. It is not recommended to use a colloidal mill for honey processing, because the temperature of the material is easy to rise during the processing, and high temperature will affect the taste. Oyster sauce can be processed with a colloid mill, but the higher power models should be chosen for recycling materials. Question: Can the colloid mill solve the problem of agglomeration of materials, such as protein powder, starch, salt in oyster sauce or MSG? Answer: Yes, no problem. Question: Can the colloid mill grind chili/pepper? Answer: Yes. It is recommended to chop the chili/pepper first, the smaller the better, and add a screw feeder at the inlet of the colloid mill. It is best to remove the chili seeds, otherwise the seeds will easily enter the groove of the gear and cannot be ground. If so, there are still many unprocessed chili seeds in the final product of chili sauce. Question: Can the colloid mill grind vegetables? Can you grind fruits, such as pipa, grapes, and apples? Answer: Vegetables: Vegetables with high water content are recommended to be finely chopped first, the finer the better. A screw feeder is added to the feed port of the colloid mill, and the material can be processed without adding water. But vegetables with low water content and high fiber, such as celery, shiitake mushrooms, kelp； bamboo shoots, water spinach, cabbage, carrots, seaweed, etc., need to be added with water, the more the better, and the higher model of the colloid mill the better grinding performance; (For low fiber vegetables, the theoretical grinding fineness can reach 200 meshes. High-fiber vegetables cannot be completely ground, there will be a lot of fibers in the finished product); Fruits: It is recommended to chop the fruit first. If the fruit has strong fluidity after crushing, such as oranges, apples, small tomatoes, pears, watermelons, pipa, and grapes, you can grind them in a circular tube. If the fluidity is poor after crushing, such as durian and banana, add some liquid first and then start grinding if adding liquid is allowed to ensure the strong fluidity. If it is adding liquid is not allowed, you need to use the square outlet, and if there is any nucleus, try to remove it first. Apples, pears and watermelons do not need to be pitted, but for fruits with large pits, they must be pitted first. In addition, fruits, especially fruits with poor fluidity, should avoid high temperatures during the grinding process, so as not to affect the taste. Question: Can the colloid mill grind peanuts, almonds, cocoa beans, sesame and other products? How fine is it? What is the output? Answer: The colloid mill can grind materials with high oil content, including peanuts, almonds, cocoa beans, cashews, sesame, etc. They need to be roasted or fried first, and the feed port needs to be with the screw feeder, and the applicable models should be with at least a 4kw motor. The output of different models is quite ditferent, please consult our sales staff for details.
