Chromite is lack or brown, The main ingredient of chromite FeOr2O3. It is shaft and granular crystal system. The hardness is 5.5 and density is 4.3 g/cm3. Because melting point of chrome oxide is 1900?,so can adjust high-temperature friction coefficient or decrease high temperature heat recession , clean the friction couple in the high temperature to increase the efficiency of the brake. Chromite can applied in brake pad drum brake or clutch.The recommended regular consumption is 2?8%
density: 4.3-4.6/cm3
chrome oxide content: =30%
screen analysis: +S 200
Their transmission and braking functions are based on the loads created by the supply of power to the clutches and brakes. Thus they are applicable to a great variety of automation systems.
DLZ1 series consist of a clutch,a brake, a transmission axis,a hood and a base. They feature no racing torque, durable, reliable and easy to install.
Powder brake
When no current flow in the magnetic coil, powder is being attached to in put drum side by centrifugal force as separate in put drum and out put drum. So the torque is not transmitted. If coil is exited by electric current, magnetic flux is generated, then torque is transmitted by the friction between powder and working side.
