Rotary batch mixer

The new 700-THCX-600-MSL blends abrasive materials in six to eight minutes with total uniformity and little to no shear, degradation or heat. Constructed of carbon steel, the mixer is intended for demanding applications, including packaged concrete; has a useable batch capacity of 600 cu. ft.; and, achieves uniformity with equal efficiency from 100 percent to 15 percent of rated capacity, regardless of disparities in batch ingredients’ bulk densities, particle sizes or flow characteristics.

The horizontal rotating vessel contains proprietary mixing flights with replaceable wear liners made of abrasion-resistant steel that tumble, turn, cut and fold material gently, preventing degradation and imparting minimal energy to the batch. The flights also direct the material toward and through a stationary, pneumatically-actuated plug gate valve for total discharge, eliminating residual that would otherwise be wasted or require manual removal prior to cleaning.

Powered by dual 60-hp drives, the rotating drum is supported at each end by two oversized trunnion rings that ride on heavy-duty alloy roller assemblies, providing long life with minimal maintenance. The design eliminates the need for an internal shaft with seals contacting material. To contain dust, the 700-THCX-600-MSL has one seal at the inlet, which is mounted externally to allow rapid, inexpensive replacement.

Twin side doors and a sliding intake chute provide unobstructed access to the mixing vessel interior, intake spout and seal area. A stationary inlet and outlet at opposite ends of the mixer allow hard connections to upstream and downstream conveyors, process/packaging equipment or storage vessels. — Munson Machinery Company, Inc., Utica, N.Y., 800/944-6644;
