Nneɛma a wɔde hyɛ mu no nkyekyem ne sɛnea wɔde di dwuma .

Mprempren, yɛkyekyɛ wear-a ɛko tia nkataso no mu akuw anan sɛnea nneɛma ahorow no te, a ɛyɛ ceramic lining, alloy lining, rɔba lining ne wear-ɛko tia composite lining. Nnuru titiriw a ɛwɔ ceramic lining plate mu ne alumina. Esiane sɛ ceramic ne ade titiriw nti, ɛyɛ mprɛte bi a wɔde dade a ɛntaa nsi a ɛyɛ oxide a wɔde di dwuma sɛ ade a wɔde to paanoo na wɔsan de ade titiriw a wɔde nkata so di dwuma no na ɛyɛ. Alloy lining plate yɛ ɔkwan bi a ɛyɛ super tough lining plate a wɔde alloy cast iron ayɛ no sɛ ade titiriw na ɛne tempered surface no abɔ mu. Ɛdefa rɔba a wɔde akata so mprɛte no ho no, ebetumi de n’ankasa elastic buffer ne corrosion resistance adi dwuma yiye de ayɛ ahobammɔ adwuma pa, ɛyɛ nea wɔde nhyɛso kɛse vulcanization mfiridwuma na ɛyɛe titiriw. Ɔporɔw-ɛko tia composite liner yɛ liner a ɛkorɔn bi a ɛka mfaso a ɛwɔ ceramic liners ne alloy liners so bom. Nneɛma a wɔde di dwuma-senthost steel plate wear-senthost steel plate no nyɛ adwumayɛ pa, twitwa, welding, ne nsiesie nko, enti, wɔde di dwuma kɛse.
