Refractory Materials for Rotary Kiln

Introduction

Rotary kiln is mainly used for non-ferrous metal metallurgy, refractory industry, cement and chemical industry. We are professional on manufacturing refractory bricks and monolithics for these industries.

Our refractory materials have good thermal shock resistance, mechanical resistance, which can protect the kiln body from the damage of high temperature and air current and extend working life of the kilns.

zhengzhou Jansincere refractory Co., Ltd.

Jansincere Refractories always firmly believe that the intention to do the product, adhere to product innovation, and ultimately to win the trust of customers
