Accura Collaidal Mill Bearings

Accura collaidal mill bearings are a critical part of any mill. They are made of hardened steel, and are designed to last for the life of the machine. They can be purchased in a variety of sizes and configurations. These types of bearings are also designed to be very accurate, which is important when it comes to grinding and sizing materials. They are also very easy to maintain, and will continue to work for many years to come.

LVDT 161 determines distance between mill rotor 180 and stator 178

Accura collaidal mill bearings comprise a series of slots extending across the rotor's inner surface. Each slot is angled relative to the next one. This configuration provides a pressure-popping effect which helps pre-macerate the incoming fluid and facilitates mixing.

An annular region around the rotor's circumference is also added to provide an increased mill rotor/mill stator gap. This is designed to help establish a cavitation field, which complements the shear-based fluid processing.

The slots on the rotor are also angled relative to the slots on the stator. This increases the rotor's pitch, counteracting the effects of a slower rotor speed. The center of each slot is 0.0125 inches wide. This varies from "d" to "D" based on the rotor's diameter.

A triangular-shaped support bracket 210 extends from the mill housing 116 and is attached to the rotor by a series of bolts. A knob 214 is also attached to the support bracket. This knob rotates a bearing sleeve 148, which moves axially. This bearing sleeve adjusts the gap between the mill rotator 180 and the stator 178. This gap can be adjusted from 0.001 inches to 0.050 inches in preferred embodiments.

Increasing rotor diameter

Increasing rotor diameter with accura collaidal mill bearings enables more efficient fluid processing. The invention involves a motor driven shaft which changes the gap between the mill rotor and the mill stator. This gap can be adjusted mechanically or electronically. The gap can be adjusted from 0.001 inches to 0.050 inches in a preferred embodiment.

The invention includes a mill rotor 180 with a primary processing surface 310. The rotor is designed to provide uniformly high shear forces to the fluid as it moves through the gap. The rotor's axial length is 5.0 inches and its center diameter is 1.562 inches. The rotor's pitch angle is a' which preferably matches the angle of the rotor's axis of rotation 320. The pitch angle is also increased with increases in rotor diameter.

The rotor 180 is supported on a shaft 130. The shaft is moved axially relative to the mill body 110. A thrust bearing 148 supports the shaft 130. A timing belt 160 engages the thrust bearing 148 and rotates the shaft 130. The timing belt is driven by a stepper motor 200. This motor is controlled by a computer 202.

Hard to calibrate

Accura collaidal mill bearings are characterized by a support system for the timing belt. The timing belt is used to regulate the gap between the mill stator and the mill rotor. The design of the belt is based on the use of a thrust bearing supported in a threaded sleeve. This system provides a clear separation between the rotor and the stator and allows the bearing to be positioned in an independent position.

The support system in accura collaidal mill bearings is comprised of a triangular shaped support bracket 210, which is mounted by a series of bolts 212. The bracket 210 extends from the connecting section housing 116. The bracket 210 contains a knob 214, which allows the adjustment of the gap between the stator and the rotor. The adjustment of the gap is controlled by a simple hand operated knob. Alternatively, a stepper motor arrangement can be used to control the gap.
