silica sand mining plant processing equipment

Silica Sand Raymond mill is a good option for grinding silica sand to fineness between 80-400 mesh. HC pendulum Raymond mill is an upgrade equipment with a higher grinding efficiency. Raymond mill is mainly applied in the grinding process of metallurgy, building materials, chemical, mining & mineral industries, and suitable for grinding medium hardness materials and hard materials. The mill is also used as a cement grinder, clinker grinder, gypsum grinder, limestone grinder, coal grinder, talc grinder, spar grinder, dolomite grinder, marble grinder, slag grinder

1.Reliable performance: this Silica Sand grinding machine using new technology plum blossom frame and pendulum roller device, the structure is more advanced. The whole set of equipment runs smoothly and its performance is more reliable

2.Energy saving and environmental protection: equipped with a pulse dust collector, the dust collection efficiency is as high as 99%, all the positive pressure parts of the host are sealed, and 3.High efficiency: our unique technology improves grinding process efficiency, the primary grinding process can be intensified for hard ores and material transport can be improved for soft ores

silica sand mining plant processing equipment

The coarse material is fed to the center of a round table rotated by an electric motor with gearbox. The material spreads down the slope of the central pile and further by centrifugal force. Conical grinding runners are pressed on the rotating material bed by means of hydraulic or pneumatic and occasionally also by spring force. The ground material passes a retainer ring at the periphery of the table, where it is picked up by a swirled air stream drawn from the lower part of the mill and lifted completely to the inlet of an internal separator. The coarse fraction is returned to the center of the table. From the separator outlet the final product reaches cyclones or filters for separation from the air, which is fully or partially recirculated to the Silica Sand grinding mill. The entire circuit is under negative pressure for dust free operation

experimental research on rheological and mechanical

Nano silica sol (NSS) grouting is an effective method to improve water blocking capacity of rock fracture and fine sand. However, the mechanical and rheological properties of NSS grout remain poorly investigated. We study the properties by (1) measuring gelling time of NSS grout with a different accelerator dosage, (2) measuring shear strength of NSS with fall-cone test, (3) measuring the permeability coefficient of NSS, (4) measuring uniaxial compressive strength (UCS) of NSS mortar with different accelerator dosage and different curing conditions, and (5) conducting scanning electron microscopy (SEM) tests on NSS mortars at the sample age of 28 days. A new parameter R is introduced to represent the amount-of-substance concentration ratio of silicon dioxide (SiO2) and calcium chloride (CaCl2) in the mixture of NSS grout and the accelerator solution. It is proven that the gelling time of NSS grout increases exponentially with the increase of R. The equation of real-time viscosity and permeability length is derived. The strength development of NSS and the stress–strain relationship of NSS mortar is observed. The corresponding relationship between the micromorphology and macro-mechanical properties of NSS mortar is revealed. Furthermore, the non-monotonicity of experimental data is discussed and a possible reason is given

The gelling time of NSS grout increases exponentially with the increase of accelerator dosage. The equation of fitted gelling time is derived through the gelling time test. The shear strength of NSS is measured through the fall-cone test. The permeability coefficient of the NSS is measured by the variable head permeability test. The stress-strain relationship of NSS mortar is revealed through the UCS test. The micro-morphology is observed through the SEM test. The weak bond of NSS explains why the stress is low and strain is large
