NC-type planetary differential is used in horizontal and vertical spiral unloading settling centrifuge, it owns the advantages of high carrying capacity, small diameter, compact structure, high transmission efficiency and big difference ratio range etc. It fits perfectly in the greater power, speed and differential speed, special in the centrifuge of high separation factors and large output torque.
<!--[if ppt]--><!--[endif]-->
NC-type differential generally use two drives, and input pulley generally have radial unloading device that it can bear greater radial force.
<!--[if ppt]--><!--[endif]-->
Precision hardened gear and internal gear, advanced design and manufacturing process are coordinating with advanced processing equipment, the major parts have passed the balancing test that can meet the performance of the centrifuge under the high speed and small vibration frequency.
<!--[if ppt]--><!--[endif]-->
When NC-type differential is debugged, it should allow both ends of the outer cover to fix by balancing correction. After deduplication, corresponding mark should be signed on both ends of the cover and the corresponding position on the internal gear so that it can be disassembled again.

Ordering notice:
Please provide type, transmission ratio, and pulley parameters when you order the NC series products.
NC series products have two lubrication methods:
1. Input pulley unloading device has been added 3 # lithium base grease before they go out the factory, and grease can be injected after three months used. When too much grease injected, they may squeeze out from a crack in the pulley and the input cover after the initial operation, but it will not impact use.
2. Differential host uses thin oil lubrication and do not inject grease when leave the factory. So, it must be injected N220 extreme pressure gear oil (for winter) or N320 extreme pressure gear oil (for summer), or other lubricating oil has the same properties. The amount is 80% of the volume, or max after unbolt with the oil filling port 30 degrees from the highest point of vertical deflection. The oil should be changed after first 300 hours usage. Meanwhile, the residual oil should be removed completely during changing. After the first oil change, it needs to change the oil per every use of 1000 ~ 1500 hours (according to the working condition).
3. It is strictly prohibited running under the conditions of oil shortage.
We also can make non-standard design according to customer’s requirements.

  • The suitable centrifuge model is only for reference, the unit should be selected according to actual use of the industry and the operation of the centrifuge.
  • This series can provide ratio of differential ratio with 11, 17, 23, 29, 35, 43, 59, 71, and 87.
  • BC39B is under development.

AnchorOrdering notice:
Please provide type, speed ratio, and lubrication method when ordering.
BC series divided into thin oil lubrication and oil lubrication. If use the grease lubrication, then the products have complete oil before they go out (No. 3 lithium grease). But, it should be injected the same grease again until complete after the machine installation and debugging,
We suggest selecting the standard products to ensure the delivery term and sparing parts supplying. Meanwhile, we can also design all types of differential according to customer’s requirements.

Horizontal Spiral Unloading Filtering Centrifuge

Horizontal Spiral Unloading Filtering Centrifuge

Horizontal Spiral Unloading Filtering Centrifuge

Horizontal Spiral Unloading Filtering Centrifuge is used for separating suspensions upon the filtration concept. For the suspended solid particles in the size range of 0.1~9mm, the centrifuge is able to perform solid-liquid separation or dewatering effectively, and provide washing function. The centrifuge is characterized by continuous operation, automatic discharge, high dewatering rate of solid phase, compact construction, high separation efficiency, convenient manipulation and maintenance, and occupying less space. With the centrifuge, the cost involved in the heat drying of the solid phase will be eliminated. The parts that are susceptive to wear off have been protected with wear resistance materials. So the centrifuge is extensively suitable for solid-liquid separation and dewatering in industries such as chemical engineering, foods, synthetic fibers, mineral metallurgy, pharmaceuticals and light industry.

NOTE:The practical production capacity is related with the nature of feedstock and separation requirements.

Main technical parameters:

Model Diameter of the bowl(mm) Maximum speed(r/min) Separation factor(xg) Productivity(m3/h) Motor power(kw) Weight(kg) Dimensions(L*W*H mm)
