1.4 Rubber liners have higher capacity of anti-wearing by fatigue and anti-wearing by grinding than metal liners, especially in the case of hard ore, when rubber liners will generally provide a service life 2-4 folds longer than that of metal ones. However, its capacity of anti-wearing by rolling and pressing is weaker, and it can not hold well repeated impact by large steel balls. Therefore, rubber liners are applied more on both feed-end and discharge-end heads of primary ball mills, on both feed-end and discharge-end heads and shells of regrinding mills and the discharge-end head of autogenous mills.
1.2 The damping and absorbing functions of rubber liners reduce noise, and the noise from rubber liners is normally lower by 10-15dB than that from metal ones;
EPDM RUBBER POND LINERS: The characteristics of an EPDM rubber sheet is determined both by the particular EPDM compound (mixture of ingredients) selected. Since any rubber made primarily of EPDM polymer can be called EPDM rubber, there are many types of EPDM and simply purchasing an EPDM sheet for use as a pond liner can be risky in the absence of information about the other ingredients which make up the majority of the formula. For example, certain curing compounds, fire-retardants, and fillers commonly used in EPDM roofing sheets rubber can be toxic to aquatic life. Pond-grade EPDM rubbers must be specially formulated and tested to be safe for plants, fish, and other aquatic life. We offer two pond-grade EPDM sheets: Pond EPDM and Conservation Technology EPDM, both of which have a long track record of safe use for pond lining.
POND EPDM: Pond EPDM is our most popular and affordable EPDM rubber pond liner. It is manufactured with the talc process (see above) which leaves a mineral talc residue that gives it a slightly shiny surface: sheet color can vary from dark black to charcoal gray, depending on the amount of talc present. White streaks of talc may be present, but will usually disappear with time. Standard sizes in 45 mil thickness follow. Sizes shown in plain type are stock sizes that generally ship within 24 hours. Sizes in italics are not stock sizes and may involve shipping delays.
