Munson Machinery releases new abrasion-resistant rotary batch mixer

Published by , Assistant Editor
Dry Bulk,

Munson Machinery, a world leading manufacturer of mixing/blending equipment, has released a new model, 700-THX-50-ARI rotary batch mixer. This machine blends abrasive materials such as concrete, premix, mortar mix, glass/cullet, fibreglass, refractories, tungsten powder and ceramics, in 1 - 3 min. with minimised abrasive wear or product degradation.

The mixer features abrasion-resistant steel material contact surfaces, internal mixing flights with easy-to-replace wear plates and radial seals for dust-tight operation.

It has a useable batch capacity of 1.4 m3 or 1 815 kg, and achieves uniformity with equal efficiency from 15% to 100% of rated capacity, regardless of disparities in the bulk densities, particle sizes or flow characteristics of batch ingredients, according to the manufacturer.

Its horizontal rotating vessel contains proprietary mixing flights that tumble, turn, cut and fold material gently, preventing degradation and imparting minimal energy to the batch. A stationary inlet and outlet at opposite ends of the vessel allow hard piping to upstream and downstream conveyors, process/packaging equipment or storage vessels.

Unlike mixers with stationary vessels that force agitators through the batch, the drum requires only a 7.5 kW motor for rotation in most applications. Optional 15 kW motors are available for mixing of materials with bulk densities in the range of 3.2 gm/cc.

The rotating vessel and internal flights lift and direct the entire batch into the discharge spout for evacuation with no residual ‘heel’ of material requiring manual removal, eliminating waste and allowing rapid cleaning.

The mixing vessel rotates on exterior trunnion rings, eliminating the need for internal shaft seals that are prone to failure when mixing abrasives.

It is equipped with an optional cage-style intensifier that is independently powered. Mounted at the inlet end of the vessel, the intensifier promotes uniform dispersion of non-free-flowing and other difficult-to-blend materials, imparting shear to reduce agglomerates into discreet particles.

Also optional are internal spray nozzles for uniform distribution of liquids over the bed of moving material.
