The rotor scale has accurate measurement and high cost performance. Shandong Lingrui can be customized

Rotor scale
Product overview
LR - PRW series powder rotor scale is a special scale for continuous weighing, batch metering and batching of powder materials Use metering equipment
It is especially suitable for the measurement of powder materials with strong fluidity, such as fly ash, pulverized coal, etc
Widely used in building materials, cement, chemical industry, coal, mining, ceramics, glass, metallurgy, grain, chemical fertilizer, feed, port, electric power, coking and environmental protection Insurance and other industries

working principle
Lr-prw powder rotor scale adopts ring balance weighing and metering structure, which is composed of reducer motor, rotor and disc
The scale body is supported by weighing support, and the inlet and outlet are soft connected
The powder material flows evenly in the half circumference of the inlet and outlet
The weight of the material in the half circumference is accurately detected by the weighing sensor
The weighing signal is converted from a high-precision digital transmitter to a digital quantity of 0 ~ 1 million on site
The signal is sent to the microprocessor controller without attenuation by digital transmission
The instantaneous flow is calculated and compared with the set flow, Change the feeding amount of the feeding equipment according to the difference to stabilize the material flow at the set flow, so as to calculate the cumulative amount of materials according to the instantaneous flow accumulation

To ensure precision Accurate feeding and advanced feedforward adjustment are adopted Section 3 U-S control system, the 3u-s control system adjusts continuously according to the set feeding amount Save powder and balance the speed of the lock, and achieve very fine Accurate, stable and continuous feeding
Rotor scale with dual control function & mdash& mdash; On the premise of controlling the feeding stability of the powder balance lock, the purpose of controlling the rotating speed of the rotor scale and improving the measurement accuracy is achieved
