The use of horizontal twin-shaft forced mixer, the shell with sufficient rigidity and strength to ensure strong mixing capacity, stirring evenly and quickly. It achieves good mixing effect for all kinds of dry concrete, semi-dry concrete and plastic concrete. The designed multi-angle stirring arms can avoid the phenomenon of concrete sticking on the shafts. When the motors working the mixing shafts are counter rotation. The mixing blades make the materials remain on boiling motion. Meanwhile, under the action of shearing force from stirring arm, the materials are mixed fully in a short time. The unique shape of the stirring arm also participates in the mixing operation, thus greatly reducing the mixing time.

Each group of the mixing blade can be adjusted easily on the direction of wear force, until it must be replaced. The mixing blade are made of high-strength and impact resistance of high-chromium wear-resistant alloy cast iron. The performance index of the mixing blade meets the standard of JG/T5045.1-93, among which HRC≥58，impact value≥5.0N.m/ mm², bending strength 600N/mm².

The liner of twin-shaft concrete mixer is made of high-chromium wear-resist alloy cast iron. Its performance index meets the standard of JG/T5045.2-93, among which HRC≥54，impact value≥7.0Nm/m㎡, bending strength≥600 N/m㎡. The normal life time will be more than 40,000 mix batches.

The deceleration system of twin-shaf concrete mixer is the closed planetary reduction mode with flywheel end synchronization. It is compact structure, high transmission efficiency,easy maintenance and long life time. It can meet the mixing requirement of different slump concrete production.

The shaft end sealing device: the shaft end supporting structure and sealing structure separation, so as to prevent sealing device malfunction in case the bearing damage. The advanced pneumatic sealing is optional.

The lubrication system of twin-shaft concrete mixer adopts the most advanced automatic grease filling system. The grease is supplied to different greasing point along the pipeline respectively. The grease into all greasing points and sealing chamber plays the role of lubrication sealing. The computer-controlled Intermittent grease injection mode ensures the minimum grease consumption while the shaft end sealing runs reliably.
