Product Description

Product Description

Lining the buckets of open-pit excavators improves the efficiency of overburden operations in "soft" soils. "Polyceramoplast" is resistant to low temperatures (down to −250 °C) and hardly reduces the internal volume of the bucket. 

Given that different zones of the bucket experience different loads (abrasion, freezing), zoned lining is applied: the composition of the plates is selected according to the required wear resistance and anti-adhesion. For each type of bucket, formulations and fastening methods have been developed to prevent plate detachment.

The residual soil on lined surfaces does not exceed 5% of the lined area per cycle, which speeds up the entire loading-unloading process and eliminates metal wear. Worn plates can be easily removed and replaced with new ones without prolonged downtime.

Company Profile

Shenyang Gelar Composite Materials Co., Ltd. is a joint venture invested by the Europe-based Gelar group, utilizing advanced European technologies and specializing in the R&D, production and sales of high-performance engineering plastics. As the manufacturing base of the European enterprise in China, we produce high-quality products by advanced production equipment, strict quality control system and continuous R&D capability. Our "polyceramoplast™"product series are composite materials manufactured from ultra-high-molecular-weight polyethylene (UHMWPE) and modified additives through modification technologies. Among them, the polyceramoplast™ α,β,γ series—polyceramic composites—benefit from unique production technology and specialized equipment, significantly enhancing the modified properties of UHMWPE to achieve superior wear resistance and anti-adhesion performance. 

Gelar aim to become a world-leading high-performance engineering plastics and composite materials manufacturer.

FAQ

Q:
Is there any confirmation that when using such lining on an excavator bucket, wet and frozen soil will not stick? Have any tests been conducted?

A:
Tests were conducted in 2011. Currently, commercial lining of buckets to prevent adhesion and freezing is being carried out—the technology is well established. For feedback, please contact the general email address.

Q:
Is it possible to use Polyceramoplast-Omega plates for grader/dozer blades (municipal equipment)? Is it possible to use them for excavator tooth points? Comparisons with steels such as 17G1S, 65G, and others are needed.

A:
Blades for graders/dozers can be manufactured: the Basis, Alpha, and up to Beta grades are suitable. Omega is too brittle for these purposes.

No grade of UHMWPE will "last" longer than the mentioned steels: steel has higher strength, hardness, and wear resistance. The advantage of Polyceramoplast is its slipperiness and hydrophobicity; such blades are suitable for delicate contact (for example, with paving slabs).

For excavator tooth points—no, the hardness is insufficient.

Q:
What is the procedure for setting the warranty period for products (policy)?

A:
Typically, we provide a warranty for the material's compliance with the technical specifications (wear resistance, tensile strength, impact toughness, etc.)—this can be considered the policy and the main aspect of the warranty.

In individual cases, we provide a warranty for the performance of the lining or product in a specific unit/mechanism (for example, a "turnkey" bucket)—for up to 1 year. The decision is made based on a completed questionnaire.

Q:
Which plates are most suitable for excavator buckets working with ore?

A:
The optimal choices for bucket lining are Polyceramoplast-Alpha and Polyceramoplast-Beta. Alpha—higher anti-adhesion properties (areas with the greatest adhesion/freezing). Beta—higher wear resistance (areas with high abrasive load). By combining the two grades, we achieve a uniform service life for the lining.

Important: soft soils—not higher than category 4. Ore does not fall into this category. Alpha and Beta have been successfully used in hoppers and chutes with ore, but in buckets—they are unlikely to perform well due to different mechanics.
