example 1

[0046] Example 1: A project AC-16 mixture uses four kinds of aggregates, namely crushed stone 9.5-19mm (A material), crushed stone 4.75-9.5mm (B material), crushed stone 2.36-4.75mm (C material), mechanism Sand 0-2.36mm (D material)

[0047] grouping:

[0048] The cold aggregate is divided into two groups according to the specifications and sizes: the first group is A material and C material; the second group is B material and D material.

[0049] One group contains the finest cold aggregate, corresponding to No. A feeding system; the other group is coarse cold aggregate, corresponding to No. B feeding system.

[0050] Corresponding to No. A feeding system cold material group: crushed stone 4.75-9.5mm (B material), machine-made sand 0-2.36mm (D material)

[0051] Corresponding to No. B feeding system cold material group: crushed stone 9.5-19mm (A material), crushed stone 2.36-4.75mm (C material)

example 2

[0056] Example 2: A project AC-25 mixture uses six kinds of aggregates, namely crushed stone 19-31.5mm (material A), crushed stone 9.5-19mm (material B), crushed stone 4.75-9.5mm (material C), crushed stone Stone 2.36-4.75mm (D material), machine-made sand 0-2.36mm (E material), natural sand 0-4.75mm (F material).

[0057] grouping:

[0058] Machine-made sand 0-2.36mm (material E) and natural sand 0-4.75mm (material F) with similar specifications are counted as one and placed in the same group, then

[0059] The cold aggregate is divided into two groups according to the specifications and sizes: the first group A feed system is A material, C material, E material and F material; the second group B feed system is B material and D material.

[0060] The ratio of E material and F material is controlled from the cold material feeding system.

[0061] Mesh selection:

[0062] The first group A No. feeding system, the maximum particle size is 31.5mm, the intermittent interval is 9...

Abstract

The invention relates to a separation feeding-type hot mix intermittent asphalt mixture blending machine and a production technology therefor. The separation feeding-type hot mix intermittent asphalt mixture blending machine mainly comprises cold aggregate feeding systems, drying rollers, dedusting systems, powder systems, hot aggregate elevators, a hot aggregate screening machine, a hot aggregate storehouse, a metering system and a mixer. The separation feeding-type hot mix intermittent asphalt mixture blending machine is characterized in that the separation feeding-type hot mix intermittent asphalt mixture blending machine comprises the two cold aggregate feeding systems, the two drying rollers, the two dedusting systems, the two powder systems and the two hot aggregate elevators; the two cold aggregate feeding systems comprise a cold aggregate feeding system A and a cold aggregate feeding system B; cold aggregates are separated into two groups according to specifications, wherein one of the two groups comprise the best fine cold aggregates and is corresponding to the cold aggregate feeding system A and the other one comprises the coarse cold aggregates and is corresponding to the cold aggregate feeding system B; the hot aggregate screening machine is provided with two separation vibrating screens with separation sieve apertures; and the two separation vibrating screens are corresponding to the two groups of the cold aggregates separated according to the specifications. The separation feeding-type hot mix intermittent asphalt mixture blending machine can solve effectively the problem of shortage of a cold aggregate storage space of the existing intermittent blending machine, improve screening ability, reduce energy consumption, increase individual output and improve production efficiency.

Description

technical field [0001] The invention belongs to the field of road construction machinery, in particular to a batch mixer for producing asphalt mixture and a production process thereof. Background technique [0002] With the rapid development of highway construction, the usual equipment in the production of hot-mix asphalt mixture is batch mixer, which mainly includes cold material system, drying drum, dust removal system, powder material system, and hot aggregate hoist. , hot aggregate screening machine, hot aggregate bin, metering system, mixer and finished product bin. The equipment is a factory-type complete set of equipment that mixes dry-heated aggregates of different particle sizes, fillers and asphalt according to the design ratio at a specified temperature to form a uniform mixture. The batch mixer is a relatively independent mixer. The units are linked to form a mixer-centric system. [0003] Due to the variety of materials used in our country, the variability is ...
