Founded in 1995 and as a member of China National Crane Conveyor Machinery Association, China Chuanda Conveyor Belt Co., Ltd. is a specialized spiral conveyor manufacturer and custom spiral conveyors designer of various kinds of conveyors, belts, pulleys, bearings, rollers, bushings and so on. Through modern scientific management, excelsior products and technological design, advanced production tools and strict testing methods, we have produced various types of conveyance equipment. In 2001, we were certified by ISO9001: 2000, which has ensured the reliability and stability of product quality. Also, we have passed Germany DQS authentication in the domestic same trade. We have established long-term relationships with some famous mechanical manufacturers both at home and abroad, such as Veit GmbH, Hashima, Oshima, Summit, and KDK companies.

The SSC Shaftless Screw or Spiral Conveyor is an alternative concept to the traditional shafted screw conveyor. Material is conveyed by an extra-heavy-duty shaftless screw that slides on a low-friction, wear-resistant liner inside the conveyor trough housing.
The U-section troughs, which are longitudinally divided, are manufactured in carbon steel or in 304 L / 316 L stainless steel, including an appropriate surface treatment. Fabricated parts except the screw, which is ultra-heavy-duty, are of the medium-heavy-duty type. The cross section of the lower part of the trough is slightly wider than the side channels to allow for the liner to be inserted in the lower trough part. After complete assembly of the trough the liner is kept in place by the upper trough side channels. At one trough end there is a vertical or flush-type outlet. At the drive end the screw conveyor is equipped with an end plate holding the end bearing assembly with flanged shaft coupling with the screw. The drive unit installed suits the application.
The SSC can be loaded from above into the open trough (standard), or through an inlet spout included in a bolted trough cover (option), or from the side through a special side inlet in the loading zone of the trough (option).

Application of Whole Tyre Crusher ZPS:
Mainly be utilized to crush whole tyres including steel wire radial tyres (meridian tyres) and common bias tyres (diagonal rubber tyres).
Structural Characteristics of Whole Tyre Crusher ZPS:
The abrasion resistant parts are made of special abrasion resistant materials (National Patent Product), they are characterized by long service life, low noise and small size. The crusher chamber coordinates with the right and left support mechanisms perfectly, the crushing power are transmitted efficiently, which ensures the good stability of equipments. The special rotary sifting device can send the unqualified fragments back to the crusher chamber and discharge the qualified fragments out the chamber, so it protects the after treatment equipments effectively. Advanced water cooling device is applied to take away the heat produced in time during crushing.
