Hornblende is black and, like all amphibole minerals, is characterized by two perfect cleavages that intersect at about 60° or 120°. Instead of breaking in broad, single cleavage planes like the micas, the cleavage surface of an amphibole mineral tends to display a large number of small, offset planes that help give the mineral a splintery appearance.
The large number of small offset cleavage planes may make it tough to spot the angles at which the two cleavages intersect. The solution is to slowly rotate the mineral in your hand and spot the flashes of reflected light. Even if offset, multiple parallel cleavage surfaces will reflect the light at one time. If you keep track of how far you rotate a given sample, you can estimate whether the two sets of flashes occur at 90° or 60°/120° from each other.
Introduce Of
Hornblende, amphibole grinder mill
Hornblende, amphibole grinder mill is for super-fine grinding materials with hardness less than 6 in Moh‘s scale and humidity less than 6 percent such as kaolin, limestone, basalt, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds. The granularity (or final size) of the finished products can be freely adjusted between 325-3000meshes (0.045-0.005mm), and the capacity (ton/hour) ranges from 0.4T/H to12T/H depending on the final size and the grinding materials.
Detailed Product Description about Hornblende, amphibole grinder mill
Hornblende, amphibole grinder mill is mainly applied to grind non-inflammable, non-explosive and brittle materials with Mohs’ hardness under six. Such as calcite, chalk, limestone, dolomite, kaolin, gypsum, and talc etc, totally more than 100 kinds of materials. Product fineness can be controlled between 300~3000 mesh (47~5 micron)
Production Line Configuration of Hornblende, amphibole grinder mill:
The whole set HGM
Hornblende, amphibole grinder mill consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems
Working Principle of Hornblende, amphibole grinder mill:
The main bearing and each dial are driven by electromotor of main machine through reducer, and numbers of rollers, which are rolling in the ring, are driven by dial through plunger. After crushed by hammer crusher, the big materials become small ones and are sent to storage hopper by elevator and further sent to the middle of first dial evenly by the electromagnetic vibrating feeder and feeding pipe. The materials will be driven to the edge of dial by centrifugal force and fall down into the ring, crushed and grinded by roller, and become powder after production of three rings. The high pressure centrifugal blower will inhale air from outside and blow the crushed materials to classifier. The rotating turbo in the powder concentrator will make the coarse powder return to the mill and reground, while the fineness will mix with the air and go into the cyclone and be discharged in the discharge bin, which is at the bottom of it. The air, which mixed with very little fineness, will be purified by impulse duster and discharged by blower and muffler.
