Compared to pressure homogenizers, colloid mills are initially centrifugal devices. The fields currently promoted include food industry, chemical industry, daily chemical industry, construction industry, other industries, plastic industry, textile industry, papermaking industry, coal flotation agents, and the environmental protection production needs of nanomaterials industries. Their advantages are simple structure, easy maintenance and operation, and suitability for materials with high viscosity and larger particle sizes. The main disadvantages are also determined by their structure. Proper usage and maintenance of colloid mills are crucial. Due to the centrifugal motion, the flow rate is not constant, and it varies greatly for materials of different viscosities. For instance, the same equipment can show a flow rate difference of over 10 times when processing thick paint materials and thin milk fluids; secondly, due to the high-speed friction between the rotating stator and the material, a significant amount of heat is generated, causing the treated material to change; thirdly, the surface is prone to wear, and after wear, the refining effect decreases significantly.

The internal gear structure offers structural advantages with a compact design and low energy consumption; the colloid mill motor is only 55KW. Imported stator and rotor core components, with unique anti-corrosion and wear-resistant materials, ensure a lifespan of over 200,000 tons. The colloid mill motor is controlled by a variable frequency drive, featuring minimal current shock and adjustable speed according to requirements. The colloid mill gap can be adjusted within the range of 0.1 to 5mm. It allows for the successful single-pass grinding of asphalt with up to 20% polymer content, with SBS particles as small as 0.1μm. The shearing and grinding capacity is 10 times that of a standard colloid mill, significantly reducing the asphalt's dwell time at high temperatures and preventing high-temperature aging. It can shear and grind various modified asphalt types, including SBS, SBR, EVA, PE, rubber powder, and rock asphalt.

Colloid mill equipment is horizontally mounted on a level concrete foundation and secured with foot bolts (it may not be secured depending on the working conditions). Check that all fastening screws are tightened (the rotor center screw is an M12 screw). Before use, turn the rotor with a wrench to check for contact with the stator and for any jamming; if any of these conditions are present, do not start the machine. Check and connect the power lines (three-phase AC, voltage of 380V, machine with protective grounding) and ensure the direction of rotation of the rotor matches the arrow on the base (rotating clockwise). Connect the cooling water and pay attention to the in and out water mouth signs. When starting the motor, first use the momentary switch to check for any noise or vibration. If anything is abnormal, immediately stop the machine, eliminate the fault, and then try again. After operation, clean the residual material inside the stator and rotor while the machine is running, first rotating the large chuck counterclockwise by no less than 90° before cleaning. Always pay attention to the grinding operation and running time before use. If anything abnormal occurs, stop the machine immediately. When disassembling the stator assembly (please note that the stator assembly 1, 2, and 3 cannot be disassembled), first remove the hopper and the in and out water nozzles, loosen the cover screws, remove the scale disk, grip the handle, rotate counterclockwise to remove the large chuck, and then lift the mill head cover to remove the stator assembly. Do not hit it hard to avoid damaging the belt wheel and destroying the machine's precision. After replacing it, secure it with nuts and screws, then install the power start device (users with conditions can also install an ammeter and indicator lights or a variable frequency drive, etc.). After connecting the power, pay special attention to the starting rotation direction, determine if the motor is rotating in the correct direction, or check if the direction from the feed pipe is consistent with the 'red warning sign' rotation arrow on the colloid mill. Do not allow for no-load rotation (insufficient liquid in the cavity) or reverse rotation.
