High-Speed Mixer

High Speed Mixer Introduction

High speed mixer, also known as high mixing machine or high speed agitator, is a traditional batch-type powder and granule mixing equipment for the plastics processing industry. Featuring a vertical cylindrical stainless steel tank, it relies on high-speed rotating paddles to complete mixing and dispersion, drying and dewatering of powders, plastic pellets, various additives, color powders and color masterbatches within a short time, as well as simple modification under friction heating conditions. Apart from the plastic & rubber sector, this equipment is also widely applied in lithium battery raw materials, fine chemicals, pharmaceutical & food, refractory materials, non-metallic minerals and other industries.

Features & Advantages of High Speed Mixer

Efficient Mixing: High-speed rotation of bottom paddles creates circulating vortex flow. Materials tumble up and down inside the tank for dispersion. A single mixing cycle only takes 3~10 minutes. Micro dosage color powder, stabilizers and lubricants can be dispersed without segregation, and material uniformity remains stable across batches.

Wide Application Range: It supports mixing of powder, liquid and solid materials, compatible with PVC resin, plastic pellets, color masterbatch, inorganic mineral powder, lithium battery powder, pharmaceutical & food raw materials, rubber additives and other materials.

Simple Modification: Materials heat up automatically through mutual friction during high-speed stirring. The tank adopts jacket structure, which can be connected with external heating or cooling medium. It meets requirements for drying of regular materials and additive adsorption, and also realizes simple surface activation and coating modification of powders, suitable for small-batch modification processing.

Wear-resistant & Easy to Clean: The tank is standard equipped with mirror polished 304 stainless steel. The smooth inner wall prevents material adhesion and simplifies cleaning. For working conditions with high-hardness mineral powder, paddles can be fitted with tungsten carbide wear-resistant coating to extend service life of core components, balancing versatility and cost performance.

Closed Dust-proof Design: Equipped with pneumatic locking lid and side-opening pneumatic discharge gate. The main shaft can adopt multiple sealing types including packing seal, skeleton seal and mechanical seal. Combined with dust removal device, it achieves dust-free closed production.

Working Principle of High Speed Mixer

The high speed mixer drives the main shaft via motor and reduction mechanism. Materials are fed into the mixing tank from the top feeding port. Driven by high-speed rotating paddles, materials undergo repeated shearing, collision and dispersion in a short time, delivering higher mixing efficiency than ordinary stirring equipment.

During continuous tumbling, collision and shearing, materials of different weight and particle size are rapidly mixed evenly. Heat generated by friction between materials enables self-heating. Hot or cold medium can be passed into the tank jacket for basic temperature adjustment to complete material drying, additive adsorption and simple modification of powder surface activation. The machine can be matched with auxiliary equipment such as dust collector, vacuum degasser and automatic liquid spraying system.

Frequently Asked Questions about High Speed Mixer

Can high speed mixer be used together with grinding mill?

It can be matched with grinding equipment, yet only suitable for batch intermittent feeding. It cannot be directly and hermetically connected continuously to the discharge end of the mill. Ground mineral powder needs to be stored in silo first, and fed into high speed mixer in batches via screw conveyor for modification and mixing. Please note that under this mode, the mill and mixer operate independently with dedicated operator for feeding, which is generally adopted for small-batch production projects.

How to select common paddles for high speed mixer?

Three-blade Paddle: Standard configuration in the industry. It delivers fast material circulation and high mixing & dispersion efficiency, suitable for most working conditions of PVC, plastic pellets and conventional mineral powder mixing with the best cost performance.

Wear-resistant Thickened Paddle: Tungsten carbide sprayed on surface. Designed for high-hardness mineral powder such as calcium carbonate and quartz to reduce paddle abrasion and extend equipment service life.

Wall-scraping Paddle: Equipped with scraper structure for tank wall to prevent ultra-fine powder adhesion and accumulation on wall, suitable for mixing color powder and high-viscosity additive systems.

What is the difference between high speed mixer and high-speed powder modifier?

High Speed Mixer: Batch-type powder and granule mixing equipment. It can finish mixing and dispersion, drying & dewatering of powders, plastic pellets, various additives, color powders and color masterbatches in a short time, as well as simple modification under friction heating. Suitable for plastic compounding, material homogenization and pre-treatment of small-batch powder.

High-speed Powder Modifier: Upgraded modification equipment developed on the basis of high speed mixer. It can be connected to the rear end of grinding mill, featuring stronger sealing performance and precise temperature control. It integrates powder dispersion, additive coating and powder surface modification functions. The powder achieves uniform coating and high activation rate to meet refined modification requirements for high-end powders.
