One. Overview

Name: LB1000 forced intermittent fixed asphalt concrete mixing plant

Model: LB1000 type

Rated productivity: 80 t/h (water content 5%, aggregate temperature 170℃)

Form: Fully automatic computer control, forced intermittent fixed asphalt concrete mixing equipment

Working voltage: 380 volts / 50 Hz

Total installed capacity: 270 kw (fuel oil, excluding finished product warehouse)

280 kw (coal-fired, excluding finished product warehouse)

245 kw (gas, excluding finished product warehouse)

Main technical features of this equipment:

A. Modular design, CAD computer-aided design, compact structure, reasonable layout, convenient installation, transition and maintenance.

B. The key parts of the equipment are manufactured with reference to Japanese and European and American technologies. The main parts of power, control and machinery are all international famous brand products, which are excellent in performance and durable.

C. The mixer mixing head, mixing arm and liner are replaceable structures, made of wear-resistant materials, and the service life is not less than 105 batches.

D. The weighing element adopts American Media products, which has a long service life, and the output signal is stable and accurate. The measurement accuracy of aggregate can reach ≤±0.5%; the measurement accuracy of stone powder can reach ≤±0.3%, and the measurement accuracy of asphalt can reach ≤±0.25%.

A． The computer control system automatically corrects the impact of material flow and flying materials in the air; the unique form of secondary asphalt weighing, that is, after the weighing starts, the system is weighed to 75% of the set value. After the aggregate and stone powder are weighed, the system After automatic calculation based on the actual value of the weighing and the set bitumen content (%), the remaining bitumen is added to ensure that the oil-stone ratio of the mixture reaches the best state.

B． A. The computer programmable controller adopts the German Siemens brand, and the upper computer is an industrial computer imported from Taiwan to ensure the stability and reliability of the equipment.

C． B. Independently developed control system software, and its friendly operation interface makes it easy for operators to master and operate; stable performance and not easy to lose data.

D． C. The bag material in the bag filter adopts NOMEX fiber produced by American Dubang Company to ensure high dust removal efficiency and long service life: the flue gas dust discharge capacity is ≤50mg/Nm3.
