BLL fiberglass spiral chute
- Product Introduction: It is a gravity separation equipment that utilizes the inertial centrifugal force generated by the spiral rotation of the slurry to separate light and heavy minerals.
- Capacity: 0.15～16t/h
- Applications: The mineral processing spiral chute is mainly used to separate iron, tin, tungsten, tantalum, niobium, gold ore, coal mine, monazite, rutile, zircon and other metal and non-metallic minerals with sufficient specific gravity difference.
- Product Improvements: There are three kinds of mineral processing chute: fiberglass chute, wear-resistant rubber lining, and polyurethane rubber lining chute, for users to choose independently.
Advantages and Features
- Huston spiral chute has high efficiency, high recovery rate, and accurate ore separation
- is light in weight, rust-proof, wear-resistant, and corrosion-resistant
- takes up little space, consumes less water, has a simple structure, and does not require power
- has low operating cost and long service life
- has strong adaptability to fluctuations in ore feed volume, concentration, particle size, and grade
- the spiral chute is cheap, easy to install, easy to operate, small investment, and fast in return
- The friction formed on the emery surface makes the mineral processing effect better than other plastic surfaces.
Working Principle
The uniform slurry is slowly fed to the surface of the spiral groove through the feeding trough installed at the head end of the spiral groove for sorting. The tail end of the spiral groove is equipped with a valve block product interception groove, which divides the sorted products into three types according to grade along the radial direction. Use the position of the adjusting valve block to change the interception width of each product, and the product accumulation hopper will collect and export the intercepted multi-head ore flows separately. The cross section of the spiral chute and the slope change of the curve are particularly suitable for the selection of fine particles.

Case Study
Except for a small number of larger particles, the ore from a concentrator plant in Haibin, Shandong is mainly distributed in the -0.15mm particle size. The mine occupies a small area but has a large processing capacity. In order to increase the service life of the spiral chute, Huston spiral chute manufacturer specifically added wear-resistant rubber to the inside of the spiral chute to increase the wear resistance of the machine according to the site selection and processing capacity of the customer’s factory. It is also acid and corrosion resistant. During the customer’s actual use of the machine, the mineral stratification was obvious, and the service life of the machine was extended by half a year compared with ordinary chutes.
