Tenda Plastic Extruder Screw Barrel

The geometry of the conveying elements enables a good transport of the product through the extruder. Each conveying element is characterized by its number of flights, its length in millimeters, and its pitch. The pitch is defined as the axial length in millimeters, required for a complete thread. Conveying elements with a large pitch have a greater conveying effect than those with a small pitch. These elements are used to forward the material e.g. at feed openings, in order to avoid that pressure increases excessively at the openings.

Kneading elements

Kneading elements are mostly used for dispersive mixing, but they are also used for distributive mixing processes. They consist of kneading discs with a certain thickness. Like the conveying elements there are several parameters by which the kneading elements are characterized. These parameters include the number of flights, the staggering angle between sequential kneading discs (in degrees), direction (clockwise or counter-clockwise) and the element length (in millimeters) . 

Backward-pumping elements

Backward-pumping elements give a good distributive mixing and as the name implies they transport the product upstream instead of downstream. They are used for performing a more longitudinal homogenization.

Other screw elements

Tenda, headquartered in Nanjing, China, is a global manufacturing and trading company in the field of high performance plastics and rubber processing equipment, extrusion solutions, masterbatch and compounding, etc. Its unit Nanjing Tengda Extrusion Company is a professional manufacturer of twin screw extruder, single screw extruder, two stage extruder and its related auxiliaries.

Ultrasonic Heat Meters(Ultrasonic Calorimeters) are kind of energy meters measuring the flow rate and heat exchange through the ultrasonic method. The ultrasonic Heat Meters get the heat consumption value through the temperature sensors. The ultrasonic heat meters are mechatronic product based on the microprocessor and high precision sensors. Comparing with the Water Meters, electornic meters and gas meters, the ultrasonic heat meters need much more complicated designs and higher technology demand. Ultrasonic heat meters is kind of high technology products with mechanism, electronics and information technology. At present, the ultrasonic heat meters are more often used in many industries,through Ultrasonic Heat Metering,can accurate to do what you want.

      Ultrasonic heat meters are consisting of flow rate sensor, temperature sensor and calculator, which has the advantages in high tense construction and easy installation. We adopt the quality ceramic transducers which guarantee the high accuracy and stability of the ultrasonic heat meters. The ultrasonic heat meters have the characteristics as following: non mechanical movement, non wear and tear, non influence from the bad quality water and low cost maintenance; horizontal or vertical installation; installed in inlet water tube or return water tube according to customers` request (should be chosen in advance); adding the RS485 according to customers` demand to reach the aim of remote meter reading in order to be centralized management.
